Functionally decompose an enterprise server-side application into collection of services that can be developed, deployed and scaled independently

A successful application typically grows in complexity as developers implement more and more features. At some point the application becomes so complex that modularity breaks down and it degenerates into an unmaintainable ball of mud. Agile development and deployment becomes impossible. The development team can no longer keep up with the needs of the business.

The Microservices Architecture pattern functionally decomposes the application into a collection of services that are easier to understand. Each service can be developed, deployed and scaled independently. The velocity of the development team increases dramatically.

For a full description of this pattern see the Microservices Architecture Pattern.
