Description

This training course will enable the attendees to understand the value proposition of Microservices as well as the implementation of this technology. You will learn about the pros and cons of breaking up the monolithic applications prevalent in the enterprise space and converting them into Microservices-based solutions.

Spring Boot is a technology stack that builds on the popular Spring Framework to allow Spring-based applications as stand-alone jar files that host their own web servers. This approach works nicely with deployment automation and rapid scaling. In this course, we will implement Microservices using Spring Boot.

Linux containers are changing the way companies think about service development and deployment. Containers play a vital role in the modern data-center, and Docker is leading the way. In this course, we will show how to package and deploy your Microservices using Docker.
