Sizing a Couchbase Server 2.0 cluster

When looking to deploy a Couchbase cluster, perhaps the most common (and important) question that comes up is: How many nodes do I need?

While there are obviously many variables that go into this, the basic idea is to evaluate the overall performance and capacity requirements for your workload and dataset, and then divide that into the hardware and resources you have available. For a high-level and visual discussion on these factors as well as general practices for running a Couchbase cluster in production, see one of my recent Couchbase Conference presentations: Couchbase Server 2.0 in Production 24x7

The sizing of your Couchbase cluster is going to be critical to its stability and performance. Your application wants as many reads as possible coming out of cache, and the IO capacity to handle its writes. There needs to be enough capacity in all the various areas to support everything else the system is doing while maintaining the required level of performance.
