6.2.2 Benefits
Workload management provides the following benefits to WebSphere applications:
- It balances client processing requests, allowing incoming work requests to be distributed according to a configured WLM selection policy.
- It provides failover capability by redirecting client requests to a running server when one or more servers are unavailable. This improves the availability of applications and administrative services.
- It enables systems to be scaled up to serve a higher client load than provided by the basic configuration. With clusters and cluster members, additional instances of servers can easily be added to the configuration. See 6.4, WebSphere Application Server clustering, for details.
- It enables servers to be transparently maintained and upgraded while applications remain available for users.
- It centralizes administration of application servers and other objects.
