A single controller within the cluster manages this synchronization. The facility assures that the same version of an application is evenly distributed. Application Center 2000 greatly simplifies overall administration with an integrated management console that supports both local and Web browser-based access. A single application image is used in order to understand underlying definitions and to avoid conflicting configuration instructions. Application scaling Clustering multiple servers is the underlying scaling technology supported by Application Center 2000.
Clustering enables servers to work in unison to support applications.
In scaling application servers in this fashion, load balancing can be achieved to assure greater throughput to end users and to maximize backend processing. As discussed later, the fail-over capacity greatly enhances reliability and availability. Application Center 2000 does not require that supported applications have pre-existing clustering APIs. Programs do not have to be modified in order to be supported in this environment. One of the greatest advances made by Application Center 2000 is reduced setup time by clustering applications servers.
