Install Pulse on Multiple Nodes (Docker)

Pulse can scale horizontally as the number of nodes or cluster size increases.

Pulse is distributed among two nodes, as illustrated in the following deployment architecture diagram:

Deployment Architecture

The diagram also shows how independent modules like Logsearch, TSDB, and FS Analytics addons can be hosted separately to distribute workload and avoid resource bottlenecks on a single server.

If the number of nodes or clusters set for a Pulse instance is significant, running all of the components on a single node may cause performance concerns.
Provides Data-High-Availability. You can set up a MongoDB (ad-db), Elasticsearch (ad-elastic) cluster for data storage and replications.

Components that can be run in stand-alone mode:

ad-db
ad-tsdb
ad-logsearch
ad-fs-elastic
ad-graphql
ad-proxy
ad-ldap
