Service-Oriented Architectures (SOA) offer a flexible solution to the integration of systems, applications, protocols, data sources, and processes into a cohesive system to support critical business operations. A major challenge in these service-based systems is how to ensure the availability and reliability of web services upon which user applications and services are built. This paper describes a highavailability SOA platform for deploying and integrating enterprise applications. This SOA platform has been used to deploy and integrate multiple large enterprise applications that are used throughout Motorola for the past few years.
