“Data caching is a very important consideration for J2EE
applications. Data caching limits the number of remote invocations
in distributed applications and improves performance of web
applications by reducing the number of calls to the persistent data
stores. Even though caching improves performance and makes your
architecture work, it can, in fact, complicate design and introduce
such complexities as concurrent code and cluster-wide
synchronization.“Once it has been decided that data caching is an integral part
of the architecture, choosing the right caching solution can prove
to be difficult. There is always an option to implement a caching
solution from scratch. This approach can have its advantages, but
will inevitably affect the project’s cost and timeline. Another
solution is to choose one of the open-source caching
products…”
