Supported HA Search
On-premise HA Search supports two kinds of HA configurations: single data center and multiple data centers.
You can configure your On-Premise Search nodes in either of these HA configurations:
- Single data center, described in Designing single data center HA configuration
- Multiple data centers, described in Designing multiple data center HA configuration
High-Availability Configurations
-
Local High-Availability in a Single Data Center
- This ensures availability in a single data center deployment through the use of redundant and load-balanced nodes for the web application, cache, document conversion, and databases.
-
Geographically-distributed High-Availability Across Multiple Data Centers
- This configuration ensures availability across multiple data centers in the event of a disaster affecting the active data center through the use of redundant (but not hot) nodes for the web application, cache, document conversion, and databases. Note that you cannot have Jive running in multiple data centers simultaneously.
Cloud environments differentiate between local and geographically-distributed high-availability setups, allowing for optimized disaster recovery strategies and seamless failover processes across data centers.
To understand what you need for your HA search configuration, see Capacity and scaling considerations and Required nodes for an On-Premise HA Search service.
The following diagram shows the simplest HA configuration for search.
