Microservices
Description
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 various frameworks
