Best practices

Let's understand some best practices and considerations that you, as an administrator, need to keep in mind while configuring a Couchbase cluster.

Cluster design

While designing a Couchbase cluster, we need to think in terms of RAM, CPU cores, the number of nodes, and disk I/O:

• RAM: The most crucial component in a Couchbase cluster is the RAM. The optimal response will be provided by the cluster whenever most of the working set data required by applications is located in the RAM. Hence, proper sizing of the RAM is required for good performance. The administrator should calculate the proper working set data and allocate enough memory for storing it to provide optimal performance, since all reads and writes will occur directly through the memory.

• Nodes and cores: How many nodes should be there in a cluster? It's better to have more nodes than fewer nodes with high-capacity hardware resources. After calculating the required memory, you can find out the number of nodes required...
