About this feature:

A basic principle of SOA is the decoupling of applications and services. This leads to increased changes to existing applications and services, as well as more frequent creation of new ones. Because more services and applications are now creating, accessing, updating, and deleting (CRUD) operational data, the ability to establish concurrent control, transactional integrity, and response performance is more important and more challenging than ever. Significantly more data is generated with CRUD operations, and the amount is unpredictable. The ability to dynamically scale the enterprise data repository and to ensure reliable availability of data services - even when the database reaches full capacity or becomes unavailable - is critical.

One of the important benefits of an SOA is the opening of legacy applications and their data stores to much wider use. An associated challenge, however, is that the legacy asset may not be architected in a way that supports the transactional demands resulting from that wider use. By providing a buffer against the legacy data store, a data grid can serve as a caching layer that scales linearly to extreme levels. IT does not have to re-architect the legacy asset; the data grid enables IT to offer broader access with high service levels.
