Event Processes are composite applications created as event-driven assemblies of microservice components. They represent the orchestration of data flow across customized microservice components distributed across the ESB network. 

Event Processes in Fiorano are designed to connect disparate applications in a heterogeneously distributed environment. Event Processes allow the logical process design to be mapped directly to physical microservice components distributed across the ESB network.


Fiorano eStudio enables intuitive visual configuration of all the elements of an event process including the components of the process, the data flow or routes between components, deployment, profile information, and layout. The event process metadata contains all the required information in XML format, which is stored in the repository.

The Fiorano eStudio enables you to create applications, configure profiles of servers and manage connections.


For detailed information on eStudio application, refer: eStudio section.

Creating an Event Process Project

A new Event Process can be developed to meet your customized requirements, which has to be built on an Event Process Project.

To create a new Event Process Project, log on to eStudio and open Server Explorer panel (Window > Show View > Other > Fiorano > Server Explorer) in the Online Event Process Development view, and perform the following actions:

  1. Right-click the Event Process Repository, and then click Add Event Process.

  2. In the Customize Event Process dialog box, provide an appropriate name, choose the category (under which the Event Process falls) from the Category drop-down and click Finish.

  • Names will appear in sequential order by default, for example, Event Process1, Event Process2, Event Process3 etc.
  • To create a new category under Event Process Repository, enter a new name in the Category drop-down field.
  • In the Offline Event Process Development view, the above steps can be followed in the Event Process Repository (Window > Show View > Other > Fiorano > Event Process Repository) panel.

Creating a Chat Event Process

Chat component initiates a chat session on two or more nodes of a Fiorano Network. This event process also demonstrates how messages flow from one microservice to the other in a Fiorano Network. 

To create an Chat Event Process application,

  1. Create an Event Process with a unique name (saved as 'Chatting_Test' in this example) that represents the process.


    To open an already added event process, do any of the following under the category where the new Event Process is added :

    • Double-click the Event Process.
    • Right-click the Event Process and click Open.


    Event Process name appears on the title. The format of this name is: <EP Name>:<Version number> [Environment]Environment which can be edited in the Properties section.

  2. Bring the component to the Fiorano Orchestrator following any one of the options below:
    • Click the category on the Micro Service Palette to display the microservices under the particular category and drag the component to the Fiorano Orchestrator.


      In case the Micro Service Palette is not visible, open it from Show View in Window menu.

    • Right-click on the Fiorano Orchestrator, go to Insert and click Service Instance.  Type the name of the service, select the microservice that's displayed and click OK.
    • Type the service name in the Micro Service Palette Search option, drag the microservice that is displayed.
  3. Repeat the above action to bring another chat component.


    Notice that these components carry default names: chat1 and chat2.

Connecting Ports to create a Route

After adding the components, they need to be linked by an Event Route so that  data flows between the two microservice instances. 

To create a route between the two components, perform the following actions:

  1. Click the output port (OUT_PORT) of chat1 and drag to the input port (IN_PORT) of chat2. This creates a connection between chat1 and chat2 which appears as route1.

  2. Similarly, create a connection between OUT_PORT of chat2 and IN_PORT of chat1, which creates route2.            


Similarly, you can copy the required components one by one from Micro Service Palette to the Fiorano Orchestrator, and then logically connect the components between their respective input port and output ports.


To run this application, follow the steps provided in Running Simple Chat Event Process section which explains about the execution of a sample event process named 'Simple Chat' present in eStudio application.

Using a Sample Event Process to create a new Event Process

Sample Event Processes are predefined examples that come with the eStudio where components will be configured and connected making it ready to work/execute. A new Event Process can be created or build-upon these predefined ones by saving it into a different category and customizing it as required.
To create an Event Process from a Sample Event Process:

  1. In the Server Explorer palette of eStudio, double-click (or right-click and select Login) EnterpriseServer to login to Enterprise Server.


    Server Explorer palette generally appears by default on opening the application, but in case it does not appear, open it from Window > Show View). 

  2. Double-click (or click on the Expand button) EnterpriseServer, right-click Event Process Repository, and then click Add Sample Event Process.

  3. In the Add Sample Event Process dialog box, choose the required examples by selecting the check boxes adjacent to the Event Process names or choose all of them by clicking Select All button and then click Finish. The Samples are available under Event Process Repository.

  4. In the Event Process Already Exists pop-up, click the below buttons as required:

    • Rename: An Event Process Customization page dialog box appears where either of the below can be done:

      • Change the name and click Finish to save the Sample Event Process with a new name in the Sample Event Process list.
      • Change the Category by choosing from the Category drop-down or typing a new name which creates a new Category.
    • Overwrite: Overwrites the Event Process to the predefined ones that come along with the system. This is used when any changes are made to the predefined sample, which needs to be reverted to the original one.
    • Ignore: Closes the dialog boxes without any changes made.
    • Ignore All: Does the same as Ignore, but used for more than one item selected (where all of them need to be ignored and dialog boxes closed)

Using a Remote Microservice Instance in an Event Process

To add a microservice with a specific configuration from an existing Event Process, right-click the Orchestrator, go to Insert and click Remote Service Instance. Then select the required service instance and click OK.

Configuring Components

Though all the components available in eStudio carry a basic configuration to run an Event Process by just connecting the IN_PORT and OUT_PORT, the configuration requires change based on scenarios.
There are two sections where all the settings related to a component are present where the run-time behavior of the component can be changed.

Configuration Property Sheet (CPS)

To view/customize the configuration attached to a component, use any one of the two options below in the Orchestrator:

  • Double-click the component.
  • Right-click the component and click Configure.

CPS appears as a dialog box or wizard where the options are more or less self-explanatory. The configuration can be tested at any point of time (on most of the components that require the option) while configuring properties by clicking Test button. It can also be saved till a particular instant, choosing to revisit, by clicking Save and Close.

  • The Examples available in the Documentation Home screen help you understand the various capabilities of Fiorano Microservices.
  • The Category sections in the Pre-built Microservices page describe each Attribute present in the respective Component CPS panels.
  • Common Configurations section describe the options that are common in most of the Component CPS panels.


To view/edit properties, use any one of the two options below in the Orchestrator:

  • Right-click the component and click Properties.
  • Open from Window > Show View

Properties section generally appears below the three windows involved in the previous sections above: Server Explorer, Orchestrator and Micro Service Palette.
Properties section has subsections where values can be edited based on the requirement, such as General, Deployment, Execution, Log Manager, Log Module Instances and Runtime Arguments.


Common Configurations section describe the options available in the Properties panel.
