Docker has matured and is expanding from being predominantly used in the build and test stages to production deployments. Similarly, microservices are expanding from being used mostly for green-field web services to being used in the enterprise as organizations explore ways to decompose their monolith to support faster release cycles. Running microservices-based applications in a containerized environment makes a lot of sense, for both build and test as well as for runtime in production. Docker and microservices are natural companions, forming the foundation for modern application delivery. However, managing microservices and large-scale Docker deployments poses unique challenges for enterprise IT. This talk describes the modern requirements for building, deploying, and operating microservices on a large-scale Docker-ized infrastructure. It covers
