Who This e-book Is For
If you're a developer who's enthusiastic about construction fault-tolerant, scalable dispensed functions utilizing Scala and Akka, then this e-book offers you a bounce commence. you have to be accustomed to Scala, yet no previous wisdom of Akka and reactive programming is required.
What you are going to Learn
- Explore useful programming utilizing Scala
- Design an asynchronous, non-blocking purchasing cart program utilizing Futures
- Understand the Akka actor version and the connection among actors and threads
- Use the Actor Supervision characteristic to construct a fault tolerant and resilient application
- Create your personal allotted process framework utilizing an Akka cluster
- Take a glance less than the hood to achieve viewpoint at the Akka engine
- See a accomplished case examine of a key worth shop with concurrent reads and writes
- Model a finite nation computer utilizing state-driven actors
Today’s web-based functions have to scale quick to take on the calls for of recent clients. Reactive programming is the answer constructed to make sure the fault tolerant and strong scaling that's crucial for pro functions. Reactive programming in Scala and Akka offers a superb platform to enhance low latency resilient, concurrent web scale purposes at the Java digital Machine.
This accomplished consultant can help you become familiar with the ideas of reactive programming with a view to construct a powerful dispensed method in Scala and Akka. Written in components, you'll first take a walkthrough of the reactive, asynchronous, and practical recommendations in Scala sooner than targeting Akka and attending to grips with the main points of real-world use cases.
Begin with an creation into useful reactive programming, prior to relocating directly to writing asynchronous program with non-blocking constructs in Scala. Get conversant in the idea that of actor-based concurrency utilizing Akka, and contours resembling Akka remoting, routing, and patience functions to construct disbursed functions. learn how to scale functions utilizing a multi-node Akka cluster and unit attempt Akka actors and familiarize yourself with kingdom machines and the way to enforce state-driven actors utilizing Akka. ultimately, placed your talents to the attempt with a case research the place you are going to simultaneously and asynchronously shop and retrieve facts from a key worth shop. through steadily operating during the Akka techniques, you won't in simple terms have the capacity to write your personal disbursed procedure, but in addition have fun with the hidden complexity in the Akka ecosystem.
Style and approach
This accomplished advisor walks you thru the fundamentals of reactive programming in Scala and Akka, explaining one of the most usually used constructs to the main complicated beneficial properties, and taking you thru construction a full-blown dispensed procedure with the aid of real-world examples.
