The business grid function in WebSphere Extended Deployment extends the WebSphere
Application Server to accommodate applications that need to perform long-running work
alongside transactional applications. Long-running work might take hours or even days to
complete, and consumes large amounts of memory or processing power while it runs.
While IBM and other companies have advanced application platforms to help with the task
of batch processing as an architect or application designer, it is important to ensure that your
applications have a strategy to minimize the duplication of code and fragmentation.
Application.Resiliency
As more applications are designed to participate in Service-Oriented Architectures, they
increase their dependency on resources outside of their control. Applications make calls to
external interfaces, such as databases, LDAP, messaging servers, SOAP-based Web service
calls, or even HTTP-based services. Suddenly, the performance of an application depends on
the external interfaces of other applications and services (Krishnamurthi & Bultan, 2005).
The availability or poor performance of external services potentially impacts the availability
of the dependent exploiting applications.
