Course Description

In this course, we will learn how to write long-term, fault-tolerant distributed applications using Event Sourcing and Akka Persistence. You'll write 1500+ lines of Akka code yourself, with guidance, and you will become a rockstar.
This course is for Scala/Akka programmers who need to design critical and long-lived distributed applications.
You probably know Akka already:
  • it speeds up the development of concurrent applications by as much as 10x
  • its demand has exploded
  • it's a highly marketable skill
  • it's incredibly fun - once tasted Akka and Event Sourcing, you'll never want to get back to databases
I like to get to the point and get things done. This course
  1. deconstructs all concepts into the critical pieces you need
  2. selects the most important ideas and separates them into what's simple but critical and what's powerful
  3. sequences ideas in a way that "clicks" and makes sense throughout the process of learning
  4. applies everything in live code
The end benefits are still much greater:
  • a completely new mental model around persistence
  • a more marketable resume
  • more enjoyable work - Akka is fun!
This course is for established programmers with experience with Scala and Akka at the level of the Rock the JVM courses. I already assume a solid understanding of general programming fundamentals.
This course is NOT for you if
  • you've never written Scala code before
  • you've never worked with Akka
The course is comprehensive, but you'll always see me get straight to the point. So make sure you have a good level of focus and commitment to become a badass programmer.
I believe both theory and practice are important. That's why you'll get lectures with code examples, real life code demos and assignments, plus additional resources, instructions, exercises and solutions.
I've seen that my students are most successful - and my best students work at Google-class companies - when they're guided, but not being told what to do. I have exercises waiting for you, where I offer my (opinionated) guidance but otherwise freedom to experiment and improve upon your code.
Definitely not least, my students are most successful when they have fun along the way!
So join me in this course and let's rock the JVM!Who this course is for:
  • Scala and Akka developers who need to design long-term fault-tolerant systems

Yes sir!! This course carries on from the Akka Essentials one, so if you follow along both, it should be no problem. It is about half the size from the first one, BUT a) It is advanced, so be prepared and b) be prepared to be amazed! Daniel explains the topics in detail and in depth so that the code, as well as the infrastructure, make sense. Having done all this work with simple actors, persistent ones seem like the next logical step. Thanks Daniel, see you in Akka Streams!!

Another great and high-quality course by Danial, as expected. Some complex topics are clearly explained with great practical examples.

Superb course! I highly recommend it if you are going to use akka your next project!

I've been using akka for a couple of years now, but I've never had the chance to work with persistence. This course was a very good and practical overview of what we can achieve with this feature.

Daniel delivers another quality course! His enthusiasm for the subject matter makes things even better.The course is well designed with useful examples.I would have liked a little more in-depth examples around the different serialization frameworks that can be used with Akka rather than writing your own.Would love to see a future update to the course that reflects what I believe it supposed to be the 'default' style of building actor systems with Akka now (Akka Typed)

I really enjoy the lessons of Daniel Ciocrlan and I have not missed any of his courses in the Scala universe ... This course in question is no different, its content is very good, I just wish I had used more "immutable state" in The Exercises. I'll have to look elsewhere. However, the course is very worthwhile

Excellent course to learn Akka persistent, with complete examples

Amazing way of explaining complex topics in a very crisp & clear manner.

Best teacher out of all teachers from classes I took from Udemy

Same as previous Rock The JVM courses: high-quality, lot of hands-on material with great examples. Learned a lot during this one too.

This course has learned so much about akka persistence that it is no longer the mystery. I think the main benefit are best practices (especially with event adapters pattern) that can save a lot of work when applying them from the begging.

I simply loved the approach on many topics that were covered very easily for a learner to grasp without much hassles to handle.:)
