BACKGROUND

[0001] The present disclosure relates generally to a system and method for designing and configuring objects in a workflow, and is particularly, but not exclusively suitable for configuring objects that utilize web-based services via a simple object access protocol (SOAP).

[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0003] Cloud computing relates to the sharing of computing resources that are generally accessed via the Internet. In particular, a cloud computing infrastructure allows users, such as individuals and/or enterprises, to access a shared pool of computing resources, such as servers, storage devices, networks, applications, and/or other computing-based services. By doing so, users are able to access computing resources on demand that are located at remote locations, which resources may be used to perform a variety computing functions (e.g., storing and/or processing large quantities of computing data). For enterprise and other organization users, cloud computing provides flexibility in accessing cloud computing resources without accruing large up-front costs, such as purchasing expensive network equipment or investing large amounts of time in establishing a private network infrastructure. Instead, by utilizing cloud computing resources, users are able redirect their resources to focus on their enterprise’s core functions.

[0004] Within the context of cloud computing solutions for data repositories, users may be asked to deal with ever increasing amounts of data, e.g., including certain date-based information stored in the data repositories. In fact, the amount of cloud- based and date-based data collected and stored in today’s cloud computing solutions, such as cloud-based repositories, may be orders of magnitude greater than what was historically collected and stored. Users tasked with automating and/or troubleshooting enterprise, IT, and/or other organization-related functions (e.g., incident tracking and/or help desk-related functions) navigate ever increasing amounts of date-based data to properly and efficiently perform their job functions. In certain embodiments, cloned data repositories may be created. With this in mind, the following embodiments are directed to improving the manner in which certain objects for certain data repositories, including cloned data repositories, may operate via

SOAP.

SUMMARY

[0005] A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below. [0006] Information Technology (IT) networks may include a number of computing devices, server systems, databases, and the like that generate, collect, and store information. As increasing amounts of data representing vast resources become available, it becomes increasingly difficult to analyze the data, interact with the data, and/or provide reports for the data. The current embodiments provide systems and methods for configuring events or actions that enable the retrieval, manipulation and/or transformation of data, in particular via an integration hub and “spoke” architecture. A spoke is a scoped application that has content dedicated to a particular application. As will be described in detail below, the integration hub and spokes enable the creation of software objects, such as flows, actions, and/or steps that make up a workflow. A workflow may be considered to be a series (e.g. a sequence) of logical steps, which represent events to be processed by a computing system using computing resources of that computing system and/or resources external to that computing system. One such spoke is a simple object access protocol (SOAP) spoke, which may be used to create data that controls workflows, and which enables access to objects and services that are accessible via a simple object access protocol (SOAP). The SOAP spoke may be invoked by a flow designer system as part of configuring and then executing a workflow. In particular, the SOAP spoke can be used by such a flow designer system to utilize SOAP functionality in order to interact with a variety of third-party services and/or objects as part of such a workflow.

[0007] In certain embodiments, a“wizard” system may provide for a graphical user interface (GUI) that includes textboxes, drop down menus, radio buttons, and other GUI controls. The GUI controls may be used to enter information useful in identifying and using the third-party services and/or objects that are accessible using SOAP via the SOAP spoke. The information may include connection information, authentication information, request information, language information (e.g., programming code or instructions), and so on. The wizard system may then automatically store configuration information that may be used via the flow designer to access the third-party services and/or objects via SOAP, as further described below.

[0017] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and enterprise- related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0018] As used herein, the term “computing system” refers to an electronic computing device that includes, but is not limited to a computer, virtual machine, virtual container, host, server, laptop, and/or mobile device, or to a plurality of electronic computing devices working together to perform the function described as being performed on or by the computing system. As used herein, the term“medium” refers to one or more non-transitory, computer-readable physical media that together store the contents described as being stored thereon. Embodiments may include non volatile secondary storage, read-only memory (ROM), and/or random-access memory (RAM). As used herein, the term“application” refers to one or more computing modules, programs, processes, workloads, threads and/or a set of computing instructions executed by a computing system. Example embodiments of an application include software modules, software objects, software instances and/or other types of executable code. [0019] Embodiments disclosed herein are directed to creating one or more components that utilize the simple object access protocol (SOAP) via a SOAP spoke. As used herein, the term“spoke” may refer to an application that is included as a subsystem of an integration hub. The term“integration hub” may be defined herein as a software system that may provide for“codeless” development and integration with the aforementioned spokes. More specifically, the integration hub may include or operatively couple with a flow designer system that provides “codeless” development of software via natural language and visual information presentation. “Codeless” development may be defined herein as software development where the creator of the software does not use a computer language., e.g., Java, Javascript, C#, and the like. Instead, the creator of the software may use natural language and visual tools to create the software, for example, by designing a flowchart-like process that may take certain inputs and executes certain actions, as further described below.

[0020] The integration hub enables the flow designer system to create certain automated processes without having to create code via traditional computer languages. Such automated processes may provide enhanced functionality by accessing any number of services, such as web-based services, that may include weather forecasting services, financial services, information technology services, engineering services and the like. Further, the flow designer system and/or integration hub may include or operatively couple with a SOAP“wizard.” As used herein, the SOAP wizard may refer to a setup assistant or user interface type that may present a user with a sequence of one or more dialog boxes that aid the configuration of objects and/or actions that make use of technologies such as REST and SOAP in order to invoke services that execute on third party computer systems. [0021] With the preceding in mind, the following figures relate to various types of generalized system architectures or configurations that may be employed to provide services to an organization accessing a cloud-platform, such as may be embodied in a multi-instance or multi-tenant framework on which the present approaches may be employed. Correspondingly, these system and platform examples may also relate to systems and platforms on which the techniques discussed herein may be implemented or otherwise utilized.

[0022] Turning to FIG. 1, a schematic diagram of an embodiment of a cloud computing system 10 in which embodiments of the present disclosure may operate, is illustrated. The cloud computing system 10 may include a client network 12, a network 14 (e.g., the Internet), and a cloud-based platform 16. In some implementations, the cloud-based platform 16 may be a configuration management database (CMDB) platform. In one embodiment, the client network 12 may be a local private network, such as local area network (LAN) that includes a variety of network devices that include, but are not limited to, switches, servers, and routers. In another embodiment, the client network 12 represents an enterprise network that could include one or more LANs, virtual networks, data centers 18, and/or other remote networks. As shown in FIG. 1, the client network 12 is able to connect to one or more client devices 20A, 20B, and 20C so that the client devices are able to communicate with each other and/or with the network hosting the platform 16. The client devices 20 may be computing systems and/or other types of computing devices generally referred to as Internet of Things (IoT) devices that access cloud computing services, for example, via a web browser application or via an edge device 22 that may act as a gateway between the client devices 20 and the platform 16. FIG. 1 also illustrates that the client network 12 includes a management, instrumentation, and discovery (MID) server 24 that facilitates communication of data between the network hosting the platform 16, other external applications, data sources, and services, and the client network 12. Although not specifically illustrated in FIG. 1, the client network 12 may also include a connecting network device (e.g., a gateway or router) or a combination of devices that implement a customer firewall or intrusion protection system.

[0023] For the illustrated embodiment, FIG. 1 illustrates that client network 12 is coupled to the network 14, which may include one or more computing networks, such as other LANs, wide area networks (WAN), the Internet, and/or other remote networks, in order to transfer data between the client devices 20 and the network hosting the platform 16. Each of the computing networks within network 14 may contain wired and/or wireless programmable devices that operate in the electrical and/or optical domain. For example, network 14 may include wireless networks, such as cellular networks (e.g., Global System for Mobile Communications (GSM) based cellular network), WiFi® networks (WIFI is a registered trademark owned by Wi-Fi Alliance Corporation), and/or other suitable radio-based networks. The network 14 may also employ any number of network communication protocols, such as Transmission Control Protocol (TCP) and Internet Protocol (IP). Although not explicitly shown in FIG. 1, network 14 may include a variety of network devices, such as servers, routers, network switches, and/or other network hardware devices configured to transport data over the network 14.

[0024] In FIG. 1, the network hosting the platform 16 may be a remote network (e.g., a cloud network) that is able to communicate with the client devices 20 via the client network 12 and network 14. The network hosting the platform 16 provides additional computing resources to the client devices 20 and/or the client network 12. For example, by utilizing the network hosting the platform 16, users of the client devices 20 are able to build and execute applications for various enterprise, IT, and/or other organization-related functions. In one embodiment, the network hosting the platform 16 is implemented on the one or more data centers 18, where each data center could correspond to a different geographic location. Each of the data centers 18 includes a plurality of virtual servers 26 (also referred to herein as application nodes, application servers, virtual server instances, application instances, or application server instances), where each virtual server 26 can be implemented on a physical computing system, such as a single electronic computing device (e.g., a single physical hardware server) or across multiple-computing devices (e.g., multiple physical hardware servers). Examples of virtual servers 26 include, but are not limited to a web server (e.g., a unitary Apache installation), an application server (e.g., unitary Java® Virtual Machine), and/or a database server, e.g., a unitary MySQL® catalog (MySQL® is a registered trademark owned by MySQL AB A COMPANY).

[0025] The inventors have recognized that there is a need to provide more efficient means of integrating the functionality of virtual servers 26 with functionality of external systems, such as systems 28. The systems 28 may provide, for example, for web-based services accessible via a simple object access protocol (SOAP). SOAP includes a messaging protocol that allows software that run on disparate operating systems (such as Windows and Linux) to communicate using Hypertext Transfer Protocol (HTTP) and its Extensible Markup Language (XML). The techniques described in further detail below enable the creation of SOAP components, which enable a workflow. Creating such components includes generating configuration data specifying from which external system 28 and from which local database (e.g. a virtual database 26) within data has to be ingested for that workflow. One example embodiment involves use of a SOAP wizard, which is suitable for proxying communications between the servers 26 and the external systems 28. Accordingly, web-based services such as weather forecasting services, financial services, information technology (IT) services, and so on, may be accessed from the virtual servers 26.

[0026] To utilize computing resources within the platform 16, network operators may choose to configure the data centers 18 using a variety of computing infrastructures. In one arrangement, one or more of the data centers 18 are configured using a multi-tenant cloud architecture, such that one of the server instances 26 handles requests from and serves multiple customers. Data centers 18 with multi tenant cloud architecture commingle and store data from multiple customers, where multiple customer instances are assigned to one of the virtual servers 26. In a multitenant cloud architecture, a particular virtual server 26 distinguishes between and segregates data and other information of the various customers. For example, a multi tenant cloud architecture could assign a particular identifier for each customer in order to identify and segregate the data from each customer. Generally, implementing a multi-tenant cloud architecture may suffer from various drawbacks, such as a failure of a particular one of the server instances 26 causing outages for all customers allocated to the particular server instance.

[0027] In another arrangement, one or more of the data centers 18 are configured using a multi-instance cloud architecture to provide every customer its own unique customer instance or instances. For example, a multi-instance cloud architecture could provide each customer instance with its own dedicated application server and dedicated database server. In other examples, the multi-instance cloud architecture could deploy a single physical or virtual server 26 and/or other combinations of physical and/or virtual servers 26, such as one or more dedicated web servers, one or more dedicated application servers, and one or more database servers, for each customer instance. In a multi-instance cloud architecture, multiple customer instances could be installed on one or more respective hardware servers, where each customer instance is allocated certain portions of the physical server resources, such as computing memory, storage, and processing power. By doing so, each customer instance has its own unique software stack that provides the benefit of data isolation, relatively less downtime for customers to access the platform 16, and customer-driven upgrade schedules. An example of implementing a customer instance within a multi instance cloud architecture will be discussed in more detail below with reference to FIG. 2.

[0028] FIG. 2 is a schematic diagram of an arrangement of a multi-instance cloud architecture 100 in which embodiments of the present disclosure may operate. FIG. 2 illustrates that the multi-instance cloud architecture 100 includes the client network 12 and the network 14 that connect to two (e.g., paired) data centers 18A and 18B that may be geographically separated from one another. Using FIG. 2 as an example, network environment and service provider cloud infrastructure client instance 102 (also referred to herein as a client instance 102) is associated with (e.g., supported and enabled by) dedicated virtual servers (e.g., virtual servers 26A, 26B, 26C, and 26D) and dedicated database servers (e.g., virtual database servers 104A and 104B). Stated another way, the virtual servers 26A-26D and virtual database servers 104A and 104B are not shared with other client instances and are specific to the respective client instance 102. In the depicted example, to facilitate availability of the client instance 102, the virtual servers 26A-26D and virtual database servers 104A and 104B are allocated to two different data centers 18A and 18B so that one of the data centers 18 acts as a backup data center. Other arrangements of the multi-instance cloud architecture 100 could include other types of dedicated virtual servers, such as a web server. For example, the client instance 102 could be associated with (e.g., supported and enabled by) the dedicated virtual servers 26A-26D, dedicated virtual database servers 104A and 104B, and additional dedicated virtual web servers (not shown in FIG. 2).

[0029] In the depicted arrangement, an integration hub system 110 may be operatively coupled to or include a flow designer system 112. The integration hub system 110 may enable the execution of third-party application programming interfaces (APIs), including objects, automated process, and so on, such as APIs that are associated with the external systems 28. The integration hub system 1 10 may enable use of one or more SOAP spokes 1 14 suitable for interfacing with the external systems 28 by using SOAP messaging. For example, automation processes created by the flow designer system 112 as further described below may use the SOAP spokes 114 to generate configuration data that enables an application running on the virtual servers to interface with the external systems 28.

[0030] As mentioned above, a spoke is a so-called scoped application containing content specific to a particular application. It is“scoped” because its functionality, and thus scope, is defined. In the depicted embodiment, a user of the of integration hub system 110 and/or the flow designer system 112 may be guided by the SOAP wizard system 116 to enter certain information, described in further detail below, in order to generate configuration data that enables a workflow to interact with services provided by the external systems 28. The SOAP wizard system collaborates with the integration hub system 110 to enable generation of configuration data that enables external SOAP services to be invoked as part of a workflow and on a development instance of the servers 26.

[0031] The configuration data created using the SOAP spokes 114 may then be published in an application repository. The application repository may then be used to create a test server instance running the scoped application (i.e. a similar SOAP spoke). Accordingly, the application may be more easily tested before being deployed. Once testing is complete, the application may be published in various ways, such as publishing to production instances of the servers 26, to online application stores, and/or via sharing facilities.

[0032] Although FIGS. 1 and 2 illustrate specific embodiments of a cloud computing system 10 and a multi-instance cloud architecture 100, respectively, the disclosure is not limited to the specific embodiments illustrated in FIGS. 1 and 2. For instance, although FIG. 1 illustrates that the platform 16 is implemented using data centers, other embodiments of the platform 16 are not limited to data centers and can utilize other types of remote network infrastructures. Moreover, other embodiments of the present disclosure may combine one or more different virtual servers into a single virtual server. Using FIG. 2 as an example, the virtual servers 26A, 26B, 26C, 26D and virtual database servers 104 A, 104B may be combined into a single virtual server. The use and discussion of FIGS. 1 and 2 are only examples to facilitate ease of description and explanation of discrete or functional concepts and are not intended to limit the disclosure to the specific examples illustrated therein. [0033] As may be appreciated, the respective architectures and frameworks discussed with respect to FIGS. 1 and 2 incorporate computing systems of various types (e.g., servers, workstations, client devices, laptops, tablet computers, cellular telephones, and so forth) throughout. For the sake of completeness, a brief, high level overview of components typically found in such systems is provided. As may be appreciated, the present overview is intended to merely provide a high-level, generalized view of components typical in such computing systems and should not be viewed as limiting in terms of components discussed or omitted from discussion.

[0034] It may be appreciated that the present approach may be implemented using one or more processor-based systems such as shown in FIG. 3. Likewise, applications and/or databases utilized in the present approach stored, employed, and/or maintained on such processor-based systems. As may be appreciated, such systems as shown in FIG. 3 may be present in a distributed computing environment, a networked environment, or other multi-computer platform or architecture. Likewise, systems such as that shown in FIG. 3, may be used in supporting or communicating with one or more virtual environments or computational instances on which the present approach may be implemented.

[0035] An example computer system may include some or all of the computer components depicted in FIG. 3. FIG. 3 generally illustrates a block diagram of example components of a computing system 200 and their potential interconnections or communication paths, such as along one or more busses. As illustrated, the computing system 200 may include various hardware components such as, but not limited to, one or more processors 202, one or more busses 204, memory 206, input devices 208, a power source 210, a network interface 212, a user interface 214, and/or other computer components useful in performing the functions described herein.

[0036] The one or more processors 202 may include one or more microprocessors capable of performing instructions stored in the memory 206. Additionally or alternatively, the one or more processors 202 may include application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and/or other devices designed to perform some or all of the functions discussed herein without calling instructions from the memory 206.

[0037] With respect to other components, the one or more busses 204 includes suitable electrical channels to provide data and/or power between the various components of the computing system 200. The memory 206 may include any tangible, non -transitory, and computer-readable storage media. Although shown as a single block in FIG. 1, the memory 206 can be implemented using multiple physical units of the same or different types in one or more physical locations. The input devices 208 correspond to structures to input data and/or commands to the one or more processor 202. For example, the input devices 208 may include a mouse, touchpad, touchscreen, keyboard and the like. The power source 210 can be any suitable source for power of the various components of the computing device 200, such as line power and/or a battery source. The network interface 212 includes one or more transceivers capable of communicating with other devices over one or more networks (e.g., a communication channel). The network interface 212 may provide a wired network interface or a wireless network interface. A user interface 214 may include a display that is configured to display text or images transferred to it from the one or more processors 202. In addition and/or alternative to the display, the user interface 214 may include other devices for interfacing with a user, such as lights (e.g., LEDs), speakers, and the like.

[0038] Turning now to FIG. 4, the figure is a block diagram illustrating an embodiment of the flow designer system 112 suitable for creating information flow objects 300 and for interfacing the flow objects 300 to the external systems 28 via the integration hub system 110. More specifically the block diagram depicts two SOAP spokes 114 which may be used, for example via the integration hub system 110 to interface the flow objects 300 with external systems 28 as part of a workflow. It is to be understood that the integration system 110, and/or the flow designer system 112 as depicted are examples only and may be included in or implemented using one or more of the virtual servers 26, the virtual DB servers 104, or a combination thereof. In the depicted embodiment, the flow designer system 112 includes a flow designer GUI 302, e.g., a visual information flow creation tool. The flow designer GUI 302 may provide for visual programming via natural languages as opposed to entering text representative of a computer program. The flow designer GUI 302 may include executable code or computer instructions suitable for creating, managing, accessing, and/or editing the flow objects 300. In the depicted embodiment, a single flow 301 is shown in the flow objects 300. It is to be understood that more than one flow may be provided in the flow objects 300.

[0039] The flow 301 may include a trigger 304 which may be“fired” or otherwise turned on by certain changed condition, such as a change in one or more records stored in a database (e.g., stored in the virtual DB servers 104). The trigger 304 may additionally be“fired” periodically, for example, as part of a schedule (e.g., hourly schedule, daily schedule, weekly schedule, monthly schedule, and so on). The trigger 304 may thus be used to initiate execution of other flow objects 300, such as sub-flow 306, Action 308, Action 310, and sub-flow 312.

[0040] In the depicted embodiment, the trigger 304 initiates execution of the sub flow 306. The sub-flow 306 may include Actions, control logic (e.g., Boolean logic, branching logic, termination logic), other sub-flows, and so on. The sub-flow 306 may additionally take in inputs and provide outputs. For example, output of the sub flow 306 may be used as input to the Action 308. The Action 308 may use the inputs provided to execute Steps 314, 316. The Action 308 may also include control logic. Steps, such as the Steps 314, 316, and may be self-contained code, such as scripts (e.g., Java, JavaScript code) provided by the manufacturer of the flow designer system 112. As an example, the flow designer system 112 may be provided by ServiceNow™ Inc., of Santa Clara, California, U.S.A., under the name flow designer™. The Steps 314, 316 may be additionally or alternatively provided by other third parties and/or coded by certain users, such as IT users.

[0041] Steps may include any number of functionality, such as requesting approval from other users of the servers 26, 104, creating records in a database table, editing the record in the database table, deleting the records in the database table, creating server tasks, logging messages, looking up database information, notifying of certain events (e.g., incidents, change requests, problems, changes to user records), executing scripts, such as JavaScript, sending email, waiting for a condition to occur, and so on. Action 310 may execute following Action 308. In turn, Action 310 may include Steps 318, 320, and upon completion of Step 320, sub-flow 312 may be executed. Once sub-flow 312 finishes execution, the flow 301 finishes. Flows, such as the flow 301, may not have outputs. The flows may be executable from external clients, such as a client coupled to the client network 12 shown in FIG. 1.

[0042] In the depicted embodiment, Steps 314 and 320 both are shown as using the SOAP Spoke 1 14 to interact with web service A 322 and web service B 322, respectively. More specifically, the Steps 314, 320 may be SOAP-based steps that may be created via the SOAP wizard 116. The SOAP spokes 114 may provide for functionality to send and receive SOAP messages. For example, SOAP envelope processing may be provided, based on an XML document. The XML document may include an envelope element identifying the XML document as a SOAP message. The XML document may further contain a header element with header information, a body element with call and/or response information, and a fault element containing error and status information. Further details of the SOAP spokes 114 functionality are described below.

[0043] FIG. 5a is a screenshot depicting an embodiment of a graphical user interface (GUI) 400 suitable for inputting certain flow objects 300 into a flow, such as the workflow, or flow, 301. The GUI 400 may be included in the integration hub 110 and used to create the flow 301 via the flow designer system 112. In the depicted embodiment, a graphical flow view 402 of a flow is shown. Indeed, the GUI 400 may be used to create and edit any number of graphical flow views that may then be executed as flow objects 300.

[0044] In the depicted embodiment, the graphical flow view 402 may start execution via a trigger 404. More specifically, if a certain user record is updated, then the trigger 404 may“fire” and execute Action 406. The Action 406 may then retrieve a set of tasks assigned to the updated user that have an open state. The retrieved tasks may then be further process via a“Do... Until” control logic. More specifically, a Do logic 408 may execute one or more Actions, such as Action 410, until the“Until” control logic 410 has its conditions met. More sub-flows and/or Actions may be added, for example, via the“+” control 414. As shown, natural language and visual composition via the flow designer 302 may be used to enable the creation of executable flow objects 300. The flow objects 300 may then be reused by clients connected to the network 12.

[0045] The afore-mentioned SOAP wizard 116 and the SOAP spoke 114 can be used to configure an action in a flow that is based upon SOAP messaging, alternatively referred to hereinafter as a SOAP step. As will be appreciated from the foregoing, creation of a SOAP step involves generating configuration data using the SOAP spoke 114 and the SOAP wizard 116. FIG. 5b illustrates representative GUI components 500 of the SOAP wizard 116. In the depicted embodiment, the GUI 500 may be used to aid a user into creating a SOAP step, such as the Steps 314, 320, by automatically configuring the required connections to a given SOAP endpoint (e.g., endpoint hosting a web-service). The SOAP endpoint typically includes connection information to a desired web service that is remote with respect to the cloud-based platform 16 and is hosted by the external system 28. Accordingly, a connection details section 502 may be used to enter connection information.

[0046] In the depicted embodiment, the connection details section 502 includes a connection dropdown list box 504 to provide for use of a connection alias or other connection, and a connection alias dropdown list box 506 that may be used to select a connection alias from a list. An endpoint section 508 is also depicted, which may be used to enter endpoint connection information (e.g., URL to use, IP address, port number, and so on).

[0047] A request details section 510 may be used to enter SOAP request details for a SOAP envelope. For example, the SOAP envelope may be built or created from an existing web services definition language (WSDL) source used to describe the web service, e.g., web services 322. To load an existing WSDL (e.g., a WSDL that may be stored in the virtual DB servers 104), a WSDL drop down list box 512 may be selected, which may list all WSDLs that are available locally. The user may alternatively activate a button 514 to launch a dialog box to access, via the networks 12 and/or 14, various WSDLs accessible from external servers 28. Regardless of how the user selects the WSDL (e.g., through local storage or from an external server), the GUI 500 parses the WSDL and then provides the XML that corresponds to the SOAP envelope in an editor section 516. The user may then select certain operations provided by the web service via an operation drop down list box 518.

[0048] A SOAP action corresponding to a selected operation is then listed in SOAP action section 520. The user may then enter certain values, such as input variables, error codes, error messages, response body information, response header information, status code information, output variables, and so on, via a data section (not shown). Additionally or alternatively, the user may edit the XML directly on the editor section 516. Such edits include importing input variables, for example dragging and dropping objects representing input variables, which are accessible via expandable portion 540 of the GUI 500 (in Figure 5b this portion is shown unexpanded).

[0049] Web services security (WS-Security) may also be provided via security section 528, including using security policies that specify how integrity and confidentiality is enforced on SOAP messages. The WS-Security may also specify certain security token formats to use, such as Security Assertion Markup Language (SAML), Kerberos, X.509, and so on. XML signature and XML encryption may also be used to provide for end-to-end security. An action outline section 526 may show all steps in an action. In the depicted embodiment, a single SOAP step and a single Representational State Transfer (REST) step is shown, but an action may include multiple steps, including steps of different types (e.g., SOAP steps, REST steps, steps based on flow designer system 112 functionality, and so on).

[0050] The techniques described herein also provide for creating custom HTTP headers when messaging via HTTP via an advanced section 529. Accordingly, a user may customize an HTTP header that is to be used during messaging of the SOAP envelope to add, for example, session id information, content type, content length, cache directives, and so on, that may be transmitted independent of the transport that the SOAP envelope may use. A name section 530 may be used to enter a name for a header field, and a value section 532 may be used to enter a value for the header field. A reset button 534 is also provided, suitable for resetting the SOAP envelope, for example, to enter new values. A save button 536 may be used to save the SOAP step, including the corresponding SOAP envelope. Each SOAP envelope may comply with W3C specifications, such as SOAP versions 1.1 and/or 1.2. Accordingly, the SOAP envelope (e.g., <envelope>...</envelope>) may include an optional SOAP header section having one or more SOAP headers (e.g.,“<header>...</header>” detailing, for example, application related information, and a body section (e.g., <body>...</body>) containing information intended for the recipient of the message. The SOAP envelope may be encapsulated or otherwise contained inside of and HTTP request (e.g., POST request). [0051] Once the SOAP step is configured as desired, the user may activate a publish button 538 Activation of the publish button 538 serves to make available the now- configured components of this SOAP step for use by one or more clients, such as the clients connected via the networks 12, 14. A SOAP step may be designated as private, for example when developing and testing the SOAP steps. Once the SOAP steps are tested, the user may change the scope to a broader scope, e.g. designate as public, and publish the steps and/or application via this publish button 538. The SOAP steps can be published in various ways, such as publishing to production instances, to online application stores, and/or via sharing facilities. Indeed, activation of the publish button 538 may then expose the now-configured components of this SOAP step that has been created to a variety of locations. Accordingly, the SOAP step, e.g., Steps 314, 320, may be more easily created, integrated, and reused into actions, flows, and so on, by a variety of clients.

[0052] FIG. 6 is a schematic diagram showing, in more detail, an exemplary arrangement of elements of the SOAP spoke 114. In this arrangement the SOAP spoke 114 comprises a database 601 and a client 603 that perform operations, including sending and receiving various messages. The database 601 may be a logical component of the virtual DB servers 104, described above, and in the presently described embodiment, it comprises tables that store step definition and instance tables that hold instances of configured SOAP steps.

[0053] The database 601 and client 603 interact with the flow designer system 112 to generate the components making up a given SOAP step as will now be explained, also with reference to FIG. 5b. As noted above, request details section 510 of the GUI 500 may be used to enter SOAP details for a SOAP envelope. For example, as described above the SOAP envelope may be built or created from an existing web services definition language (WSDL) source used to describe the web service. Access to a such an existing WSDL involves the flow designer system 112 sending a GetExistingWSDL message 605 to the database 601, which results in all previously stored WSDL files, along with a list of operations, to be sent back to the flow designer system 112 in a response. The request and response messages are shown schematically as steps 600(1) and 600(2). The contents of that response are used to populate sections of the GUI 500, such as list boxes 512 and 518.

[0054] Additionally or alternatively, a new WSDL may be loaded from a URL of an external server such as server 28 via button 514. Selection of button 514 causes the GUI to present edit boxes enabling a user to enter the URL of interest and credentials, if these are required to access the server 28, e.g. in the form of a username and a password. Thereafter and upon selection of a suitable UI command, the flow designer system 1 12 sends a LoadNewWSDLfromURL message 607 to client component 603. The contents of this message 607 comprise the URL of interest and credentials that were entered. The client component 603 may be conveniently configured to implement conventional REST services in order to access the specified URL (optionally using the credential information), retrieve the relevant WSDL and operations information, and store the retrieved information in the database 603. These request and response messages are indicated by steps 602(1 )-602(3). It will be noted that in the currently depicted embodiment, the database 603 returns a response to the flow designer component 112 at step 602(3), and this response comprises operations information that can be used e.g., in making the relevant operation(s) available for selection via list box 518 in the manner described above. In a similar manner, a WSDL created by a user using editor section 516 of the GUI 500 may be loaded into the database 603 by client 601 in response to a LoadNewWSDLfromDoc message 609, in which case the message 609 comprises a WSDL document, which may be syntax checked by the client component 601 prior to sending to the database 603 for loading into the relevant tables.

[0055] FIG. 6 also shows the flow designer system 112 sending SelectOperation message 611 to the database 603. Programmatically, this message is created and sent when an operation is selected via list box 518. The message is sent to the database 603 (step 604(1)), and this causes the database 603 to respond with a suitably configured SOAP message (step 604(2)) corresponding to the selected operation. This operation (i.e. SelectOperation message 611) may be invoked at the time of configuring a SOAP step, for example as part of testing during the aforementioned private testing phase, and it may also be invoked when executing an already configured SOAP step.

[0056] FIG. 7 is a flowchart illustrating an embodiment of a process 700 suitable for implementing SOAP requests and responses using components of a now- configured SOAP step, which may have been configured using the interface 500 in the manner described above. The process 700 may be implemented as computer instructions or code executable via the processor(s) 202 and stored in the memory 206. The process 700, for example, may be executed via the flow designer system 112 and/or the integration hub 110.

[0057] After a start block 702, the process creates (block 704) an HTTP request that contains a SOAP envelope, such as a SOAP envelope configured using SOAP request section 510 of GUI 500. It will be understood that this SOAP envelope may be one that is configured while setting up the SOAP step using GUI 500, and that process 700 may be invoked once or shortly after setting up the SOAP step. Alternatively it may be one that has been previously configured and is now being invoked as part of a workflow, for example as one of the action inputs 526 shown in FIG. 5b. In that case, the integration hub 110 will make a call to the SOAP database to retrieve relevant components of the configured SOAP step in the manner described above. Either way, the HTTP request may contain or otherwise“wrap” a SOAP envelope in XML and comprise various SOAP sections including a SOAP header section which may include one or more SOAP headers and a SOAP body section which may include one or more body sub elements as defined by SOAP W3C specification 1.1 and/or 1.2. For example, an HTTP POST request may be created, to include certain SOAP information described in more detail below. The process 700 may then set (block 706) an endpoint for the HTTP request based on connection information. For example, when using a WSDL, the path to the WSDL may be used. Connection information may be connection information previously provided via the connection details section 502 of the GUI 500.

[0058] The process 700 then determines (decision 708) if authentication has been configured for the HTTP request. If authentication has been configured, then the process 700 adds (block 710) an authentication header to the HTTP request. If no authentication has been configured (see decision 708) or after adding authentication (block 710), the process 700 then adds (block 712) a SOAP action to the HTTP request. For example, a SOAP action that was selected via the SOAP action section 520 of the GUI 500 is added (block 712).

[0059] The process 700 then determines (decision 714) if HTTP headers are configured. For example, HTTP headers may be configured by the user via the advanced section 528 of the GUI 500. If HTTP headers are configured in this way, the process 700 then adds (block 716) the HTTP headers to the HTTP request, for example based on the information previously entered in the advanced section 528 of the GUI 500. The process 700 may then determine (decision 718) if WSS Security is enabled. For example, WSS Security may have been enabled via the WSS Security section 528 of the GUI 500.

[0060] If WSS Security is enabled (decision 718), the process 700 applies (block 720) WSS Security to the SOAP request envelope. For example, certain security policies may be applied based on user preferences. The process 700 then creates (block 722) the SOAP envelope, for example, by adding a SOAP header section and a SOAP body section to the HTTP request based on the information gathered in previous blocks of the process 700. That is, XML corresponding to the SOAP envelope is written into the HTTP request to comply with W3C specifications, such as SOAP versions 1.1 and/or 1.2 specifications.

[0061] The now SOAP-formed HTTP request is ready to be sent (block 724), for example, to the external system 28 so that the external system 28 can process the request and return results. With reference to blocks 726 and 728, responses to such a SOAP-formed HTTP request can be referred to as“data pills.” It may be understood by this term that the response sent by the external system 28 is a data item that is the flow designer system 112 for use in subsequent processing of e.g. a workflow of which this SOAP step is a part.
