Video Description

Build smaller, lighter, and faster microservices for JVM languages

In Detail

Microservices are an architectural method and pattern for application development. Microservices is an architectural style and pattern that is becoming hugely popular and is adopted by many organizations because of the advantages that it offers. It is an approach to building asynchronous, non-blocking, and failure-resilient applications.

This learning path begins by showing you how to build smaller, lighter, and faster services that can be implemented easily in a Java production environment. We then move on and focus on building microservices in Scala. It addresses the best practices and common pitfalls in microservice architecture and useful implementation strategies in Scala. Finally, we cover how to build reactive microservices using Akka and Akka HTTP, which adhere to the principles underlying the Reactive Manifesto.

Prerequisites: Experience with Java and Scala is necessary
