High availability and workload sharing

Use these topics to learn about high availability and workload sharing.

WebSphere Application Server high availability
The WebSphere® Application Server high availability framework eliminates single points of failure and provides peer to peer failover for applications and processes running within WebSphere Application Server. The WebSphere Application Server high availability framework also allows integration of WebSphere Application Server into an environment that might be using other high availability frameworks, such as HACMP, in order to manage non-WebSphere Application Server resources.
Workload sharing
You can configure multiple service integration messaging engines to distribute workload across multiple application servers. This allows you to scale out your system to handle larger workloads.
High availability
You can make messaging engines highly available in the service integration environment.
Service integration high availability and workload sharing configurations
The configuration of messaging engines in service integration is very flexible. You can have a single messaging engine that does not provide high availability or workload sharing. With a cluster bus member, you can have a single highly available messaging engine. Alternatively, with a cluster bus member, you can have multiple messaging engines that share workload, or that share workload and also provide high availability.
