There is considerable attention being paid to service oriented architectures (SOA) and their promise of leveraging new and existing application components - services - in composite applications that may span multiple business units within an organization. While the construction, or enablement, of these services is well defined, what is often left as an assumption is that once deployed, the service will simply be available. The reality is that if consideration is not given to the reliability, availability and recoverability of your services, then you may find yourself leaping from the frying pan and into the fire. This presentation will discuss the use of service virtualization and grid technology to enable service execution. Using existing grid technologies, organizations can achieve guaranteed, horizontal scaling of service execution across the entire computing infrastructure, regardless of demand. The result is an infrastructure for deploying, managing and scaling services that delivers the confidence that, when called, your service will be available.
