Learning Path: Akka: Building Applications and Microservices with Akka

Video Description

Know the art of creating applications and microservices

In Detail

If you’re looking at building distributed, concurrent, fault-tolerant and scalable applications with ease, Akka is the go-to tool for it. This Learning Path delivers a clear and practical introduction to the Akka toolkit, explaining the key components you need to know to get up and running with developing applications of your own. You will learn about the actor system, how to create hierarchical structures in Akka, and how to make routes in order to send messages to other actors. We will look at other use cases such as building an actor that can change its behavior during runtime. You will then create stateful actors, work with a cluster system, and work with remote actors.

Then, this Learning Path will make you understand how to build Reactive microservices using Akka and Akka HTTP, which adhere to the principles underlying the Reactive Manifesto. You will delve deeper into concepts such as Responsive, Resilient, Elastic, and Message-Driven and will see how microservices should be designed to adhere to those principles. By the end of this Path, you’ll be well-versed in creating applications and microservices.
