Description

Depending on the type of communication (Synchronous / Asynchronous), on the role played by GreenVulcano® ESB (active / passive) and on the response management, it is possible to have from a minimum of one to a maximum of four operations constituting a single interaction client - server.


GreenVulcano® ESB Configuration

GreenVulcano® ESB is configured for managing four paradigms of communication:

Synchronous-Synchronous

Synchronous-Synchronous

The Synchronous-Synchronous paradigm takes place following the Client -> GreenVulcano® ESB -> Server direction.


The following table shows its properties:

Client GVESB Workflow Number Server
Communication Synchronous 1 Synchronous

Synchronous-Asynchronous

Synchronous-Asynchronous

The Synchronous-Asynchronous paradigm takes place following the Client -> GreenVulcano® ESB -> Server direction.


The following table shows its properties:

Client GVESB Workflow Number Server
Communication Synchronous 1 Asynchronous

The decoupling of communication can happen in two ways:

  1. plugin->server->jms
    GreenVulcano® ESB, using a plugin, invokes the serve and wait its response into a queue jms, bmq, etc.
  2. jms->server->jms
    GreenVulcano® ESB enqueues into a jms queue shared with server and wait for the response into another jms queue.

Asynchronous-Synchronous

The Asynchronous-Synchronous paradigm takes place following the Client -> GreenVulcano® ESB -> Server direction.
