Clustering

For increased reliability and performance, Liferay can be clustered. This way, if one server fails, another server continues serving data.

Liferay can be configured in both a horizontal clustering or vertical clustering approach. In a horizontal cluster, each node runs on a separate machine. In a vertical cluster, multiple virtual Java machines run on a single machine.

Here you’ll learn how to

  • Configure a database for a clustered environment
  • Configure Elasticsearch for a clustered environment
  • Run two Liferay nodes in a horizontal cluster

The first step is configuring a database.

Let’s Go!
