Installation topologies
This page describes recommended starting points for Pulsar deployments.
-
SANDBOX (or Pulsar Standalone) is an all-in-one single-node deployment that is useful for taking Pulsar for a test drive.
-
DEVELOPMENT is a 3-node deployment that is not highly available, but able to maintain parity with the TESTING environment.
-
SINGLE REGION TESTING ENVIRONMENT is a highly-available 3/3/3 deployment.
-
HIGH-AVAILABILITY PRODUCTION ENVIRONMENT is a highly-available deployment replicated across 3 zones in 1 region.
|
The number of nodes in a highly available cluster depends on the number of zones in the region. We recommend aligning the replication factor with the AZ count, so in this example, 3 zones and a replication factor of 3. |
