Beschreibung

Together, microservices and Docker containers are dramatically improving the way large organizations build, deploy, manage, and scale their applications. Now, for the first time, there's a complete, practical guide to using them together.

Parminder Kocher shows how to leverage these technologies and paradigms to drive exponential improvements in DevOps effectiveness, on-demand scalability, application performance, time-to-market, reuse, and application reliability. He also explains why microservices and containers should be deployed in combination -- and why deploying only one or the other can make things worse, not better.

Microservices and Containers also offers indispensable detailed guidance for migrating monolithic application architectures to microservices and containers. Kocher presents a complete transition roadmap, plus a start-to-finish case study showing how to transition a large SOA system to microservices.
