Course Overview
A very important part of modern software development is the new discipline of Cloud-enabled microservices, and part of this is PAAS (Platform as a Service) which allows deploying such apps into production with the minimum effort. This course will introduce the participants into microservices and to its implementation with the Pivotal Cloud Foundry.
Audience
The course is intended for software architects and engineers.
