High Availability and linear scalability
Neo4j HA architecture provides clustering of Neo4j servers and implements a master-slave
architecture.
As shown in the preceding diagram, each Neo4j server instance has two parts: one is the
Neo4j HA database and the other is the cluster manager. Neo4j HA database is responsible
for storing and retrieving the data, and cluster manager is responsible for ensuring a HA
and fault-tolerant cluster.
Neo4j HA database directly communicates with the other instances for data replication
with the help of cluster manager.
The following are the features provided by cluster manager:
• Maintaining and tracking of live and dead nodes
