Nirmata is an enterprise platform that uses Netflix OSS like Eureka, Zuul, Ribbon, and Archaius to build cloud applications. It allows users to model their business services and deploy them along with infrastructure services to sandbox environments using Docker containers. Services are deployed by launching Docker containers from a central repository in a specific order to ensure dependencies are met. Nirmata addresses challenges in running Docker containers together by configuring ports, service communication, and dependency injection.
