You can set up a WSO2 Enterprise Integrator cluster with a third-party load balancer as depicted in the diagram below.
The following sections give you information and instructions on how to cluster different profiles of WSO2 EI:
- For most of the production deployments, which involve multiple profiles you need not share the Registry DB or User DB among different profiles. Instead, you need to share them only within the instances of the same profile.
- The third-party load balancer is not applicable for the message broker profile.
- The Micro integrator profile of WSO2 EI does not support clustering yet. For more information on the Micro Integrator profile, see Working with the Micro Integrator.
