What's new in this release

WSO2 EI 6.3.0 is a major release that is shipped with the features explained below.

Introducing the Micro Integrator profile

In comparison with the conventional ESB profile, the start-up time of the Micro Integrator profile is considerably less, which makes it container-friendly. Thus, it is ideal for microservices in a container-based environment. Almost all the important features that are available in the ESB profile are available in the Micro Integrator profile as well. The database-based registry is not available in the Micro Integrator profile. Instead, it has a file system-based registry, which provides the same functionality.

The below features of the conventional ESB profile are removed from the Micro Integrator profile because they are not required for a deployment based on a Microservices Architecture (MSA).

  • The Management Console

  • Support for multiple tenants in a single virtual machine

  • SVN-based deployment synchronization

  • Hot deployment for CAR files and Synapse artifacts

  • Built-in Hazelcast-based clustering and task coordination

Also, currently, the Micro Integrator profile will entail the following limitations.

For more information on the Micro Integrator profile, see Working with the Micro Integrator. Also, for instrcutions on trying out a simple use case using the micro Integrator proifle, see Sending a Simple Message to a Service Using the Micro Integrator.
