Akka anti-patterns: Stateless actors

What is the importance of actors and why stateless actors make little sense? In this article, Manuel Bernhardt briefly explains the main purpose of actors and their state.

Trivial pursuit

How well do you know your Akka trivia?

It’s time for another programming pub quiz! This week, we’re testing your knowledge about Akka. Do you know everything there is to know about this toolkit for building concurrent applications on the JVM?

How-to

A tour of Akka cluster – Cluster sharding

The tour of Akka cluster continues! In the previous article, we learned how to use techniques for making a reactive payment processor resilient to failure using Akka Cluster. Here, Manuel Bernhardt takes a closer look at how to scale out the reactive payment processor application using cluster sharding.

Let's go exploring!

A tour of Akka Cluster – Akka distributed data

How can we make building distributed systems easier? In this article, Manuel Bernhardt explores one useful tool in the Akka toolbox: Akka Cluster. Today, we’re taking a closer look at one module, Akka Distributed Data, and how it can be used to build an example reactive payment processor.

Actors are analogous to Lego or Minecraft blocks

Akka clusters: All about Cluster Aware Actors

The fundamental building block of Akka actor systems is an actor. In a way, actors are analogous to Lego or Minecraft blocks: With the simple building blocks of Lego and Minecraft, it is possible to craft magnificent structures. In this article, Hugh McKee, developer advocate at Lightbend tells you everything you need to know about cluster aware actors.

How Akka is used to create distributed systems or clustered virtual machines

Akka clustering and remoting

While there is a wealth of documentation around Akka, based on Lightbend’s real-world experience with users and customers over the last few years, they realized that there is a need for tutorial-style tips that focuses on different aspects of Akka. In this post, Hugh McKee focuses on Akka clustering vs. Akka remoting.

SMACK — Next generation Big Data

Big Data becomes Fast Data

Big Data is changing. Buzzwords such as Hadoop, Storm, Pig and Hive are not the darlings of the industry anymore —they are being replaced by a powerful duo: Fast Data and SMACK. Such a fast change in such a (relatively) young ecosystem begs the following question: What is wrong with the current approach? What is the difference between Fast and Big Data? And what is SMACK?

Akka anti-patterns: being out of touch with the hardware

Choosing Akka as a tool is often – if not always – driven by the need for good performance. Surely, the actor model itself is appealing as a means for organizing and reasoning about code, but this isn’t in itself a good reason enough to use the Akka toolkit.

Event-driven architecture

Reactive Microservices with Scala and Akka

In this article, Vaughn Vernon, author of “Implementing Domain- Driven Design”, “Reactive Messaging Patterns with the Actor Model”, and “Domain-Driven Design Distilled”, will teach you a first approach method to designing microservices, giving you a workable foundation to build on. He will introduce you to reactive software development and summarize how you can use Scala and Akka as a go-to toolkit for developing reactive microservices.

JAX Magazine — October 2016 — Reactive programming with Scala, Lagom, Spark, Akka and Play

Reactive programming is gaining momentum but people are still reluctant to jump on the bandwagon. To help you overcome the fear of the unknown, we decided to ask Scala, Lagom, Spark, Akka and Play experts to explain how these elements coexist and work together to create a reactive universe. This JAX Magazine issue is packed with goodies — it’s our treat!
