Load balancing

Load Balancing with LogicalDOC

The purpose of this configuration is to maximize the performances distributing the CPU and RAM loads among a set of nodes called a cluster. The most part of the stress in a large installation is due to the operations of parsing, indexing and search. So care must be taken in the full-text engine.

We will use the following technologies:

• JGroups to cluster LogicalDOC instances
• Solr as indexing and search engine

Poposed configuration

• Load balancing: hardware balancer
• Database: the database is shared among all nodes. It could be a clustered database.
• Filesystem: we will use a shared filesystem common to all nodes. We can use the multiple volumes and/or dedicated NAS.
• Application Server: each node is a single LogicalDOC instance with its own full-text engine
