WSO2 key manager

Question

I am working on implementing API Manager 1.5.0 in a clustered envrionment. The store and publisher are together on one node, the key manager and gateway clustered on other servers.

We have multiple gateway nodes in a cluster (we don't have an ELB but are using DNS round robin entries to balance between IPs).

When working through the document: http://docs.wso2.org/display/CLUSTER420/Clustering+API+Manager it indicates that "versions above 1.3 should use the same user store and that Governance Registry and Key Manager should be on the same gateway node." Does it mean logically? Because I'm planning on having a cluster of servers for Gateway and Key Manager products.

Prior to API Manager 1.4.0 the publisher and store could use different user stores. Normally publisher app is used by internal developers of an organisation (due to this the user store being used by publisher can reside in a highly secured network). Since the store app is meant to be used by external users, user store for this can come from a leniently secured network. Multitenancy was introduced in API Manager 1.4.0. If API Manager is configured to have several tenants, then it's required to use the same user store for publisher and store. Same is applicable for registry database. If you are planning to create a multi tenanted APIManager environment, then publisher, store, key manager and gateway should have governance and config mounts created. And the same database should be used as the underlying database.
