SOA is widely adopted for easy integration, development flexibility and leverage, and business agility. However, the inherent complexities and overheads in today's common SOA platforms make the running of stateful business-critical applications seem impossible. In this session, we will demonstrate that SOA ceases to be an oxymoron to high performance when exploiting simple and open, yet powerful technologies such as Spring and Space Based Architecture as the SOA execution environment. We will outline a clear path for turning existing applications into linearly scalable architectures that scale on-demand across a pool of machines, while discussing issues such as loose versus tight coupling, event driven messaging, synchronization, SLAs and high availability, and migration of legacy applications.
