a good post about how to solve puzzle architectural/integration/merge problems using soa technologies

How can you keep a large, redundant, entrenched, heterogeneous portfolio alive and responsive to the business, while building for the future?
_The go-forward application portfolio should be services-based, and product offerings should be assemblies (compositions) of services, business processes, events, and user interfaces, packaged by industry, and configurable by end customers.
_For incremental gains (refresh, new features, migration), services and data stores developed for the go-forward application should be injected into the existing applications.
_To facilitate interactions across domains and/or redundant systems, the existing applications should have access to a common integration mechanism.
_Since no one can afford to start from scratch, the existing applications can be mined for assets that serve as providers in the go-forward portfolio.
