Couchbase provides a standalone Moxi component that enables scalable deployments across multiple web application servers. The best practice is to install one standalone Moxi per web application server, and then point web applications to the standalone Moxi instance on its own server. The Moxi component then communicates directly with the Cluster Manager (specified via the HTTP/REST URL supplied upon Moxi startup). This Moxi component communicates with the Cluster Manager and is aware of cluster settings and changes.
