Course Description
This course kicks off by showing you the steps involved in making your application cloud-ready. Moving on, it delves into the various aspects involved in deploying your application and running it on Cloud Foundry. It also shows you how Spring Boot and PCF tremendously increase developer productivity. Later, we address the core challenges that Java developers face while developing PCF applications, such as understanding what PCF is and why companies adopt it. Then you'll delve deeply into more advanced topics such as integrating apps with the circuit-breaker dashboard, the cloud discovery server, and the config server. We will also cover highly-available PCF deployment models, as well as common CI pipelines to PCF with Jenkins. Further, we will explore the theory behind Hystrix and the circuit breaker pattern, and go on to learn patterns for config repositories and the config server.
