WSO2 Enterprise Integrator, deploying cluster with multiple machines

1
votes

I'm trying to understand clustering of WSO EI. We can deploy each instance of WSO2 to separate Virtual Machines and place load balancer to make them work as one.

However, there are several questions which documentation does not answer.

  1. Where shared database should be located? Do I need to deploy separate Virtual Machine just for database?
  2. Where loadbalancer should also be located?

I can understand how to create cluster when single Virtual Machine is being used, but when its about multiple Virtual Machines it is hard to understand.

When I want to launch multiple instances in one Virtual Machine, it has its own question:

It depends. As you understand all instancess shall share a single database, technically it is not important where the database is (separate VM, one of the wso2ei VMs, ..). However - most of the time you deploy multiple VM for reliability reasons and then the reliability should concern the database too. Then separate DB instances (or DB service) would be more appropriate.

Where loadbalancer should also be located?

It is the same consideration as for the databases.

Yes. Create copies, set their port offset and you're good to go.
