The REST paradigm for application modernization and integration

Monolithic and massive applications are being modernized and migrated to cloud environments in order to reap all the originally envisaged benefits of the cloud computing model. Microservices are emerging as the most optimized building block to produce enterprise-scale applications. Not only for development but also for application modernization, microservices are being touted as the most suitable approach. That is, legacy applications are being systematically partitioned into multiple interoperable, portable, publicly discoverable, network accessible, reusable, composable, fine grained, technology-agnostic, containerized, horizontally scalable, and independently deployable microservices.
