- Grow as an engineer in this ultimate guide to ZIO 2.0.
What is ZIO?
ZIO is a Scala toolkit that allows us to write powerful, concurrent, and high-performance applications in Scala using pure functional programming.
Zay What?!
ZIO describes what it means to perform an “effect” in your code. It is a powerful model that allows us to compose any kind of actions, deal with parallelism, concurrency and coordination, all strongly typed with Scala’s unparalleled type system.
On top of the main ZIO “effect” type, the ZIO library comes with powerful tools built on battle-tested practices and design patterns, so we can write more easily composable code.
The end result is powerful applications, fewer bugs, more expressive and easily understandable code, and most importantly, more peace of mind and productivity for us as Scala developers.
This is what you’ll learn in this course.
How This Course Works
How this ZIO course works
ZIO is pragmatic and so are we.
As with anything at Rock the JVM, this course is hands-on. We start from first principles and don’t assume any ZIO experience. We discover ZIO effects and how to use them, then we’ll learn how to compose complex code, how to introduce parallelism and concurrency to our applications, how to run critical code flows safely and how to test everything, all through practical examples and exercises. In total, we write more than 3000 lines of code in this 13-hour course.
It’s not just about the ZIO APIs, though - this course will teach you timeless principles for pure functional programming and high-performance applications so that you can take them with you even if you stop using ZIO (or Scala).
This course deconstructs and sequences all the important topics in ZIO. You don’t need any other resource once you start. Just sit back and do the work with me on camera.
In this ZIO course, we go from practice to theory, until pure functional programming gets deep in your bones as a Scala developer.
You can write both Scala 3 and Scala 2 in this course, as we support both.

My team is expanding the use of Akka in our products so I needed a quick introduction on this topic. I have tried a couple of courses but the introduction to Akka was always too abrupt, too hard to comprehend. I blamed Akka for this as being too hard to explain. This was until I was exposed to the Rock The JVM courses which were an absolute delight when it comes to presenting such complex topics in such an easy to understand way. And Daniel has not stopped at Akka but has added to his portfolio amazing courses on Scala and Spark too. It seems like he is quite enjoying taking such challenges like complex technologies and making them so simple for everyone. I have instantly recommended Daniel’s work to my team, which helped them immensely with taking their skills to a new level, and I do recommend these courses to anyone who wants to have the fastest ramp-up in these tough but popular technologies.

From Scala, to Akka, to Spark, Daniel delivers exceptional material in each and every one of these technologies. I’ve been using them for a long time and there is always something new I will discover from him. The level of detail he gets into as well as the way he delivers material is mindblowing. I personally find his latest course Spark Optimization pure gold and one of a kind. I’ve been using Spark for a year now and I haven’t even thought how much you can leverage query plans to make such optimizations. I can’t stop thinking every time, how he manages to go so deep - because using a technology is one thing, but knowing its internals so well and how everything works behind the scenes is another story when it comes to distributed systems. Long story short Daniel is definitely the best instructor I’ve come across and each one of his courses is the best resource you can find online. Kudos for all your work and knowledge sharing.

Daniel’s courses on Scala and Big Data are the best in class. I’ve been in touch with Daniel’s teaching and courses since early 2018. The first course that I took from him was Scala & Functional Programming; I was skeptical about it because over the internet there are many courses you can find, but few really worthy. I remember the very first day when Daniel started to speak and shared his examples - I started to love Scala, and then more as we went on. I am with Scala for the last 5 years now, but never ever has anyone explained to me or gave me comparable resources to Rock the JVM. Daniel gave me a shift in life and helped me crack top tech company interviews. His courses on big data are a must for any aspiring big data developer or data enthusiast. I highly recommend Daniel as an educator both online and on campus.

Meet Rock the JVM
Daniel Ciocîrlan
Founder, Rock the JVM
I'm a software engineer and the founder of Rock the JVM.
I started Rock the JVM out of love for Scala and the technologies it powers. They are amazing tools, and I want to share as much of my experience with them as I can.
I've taught Java, Scala, Kotlin and related technologies such as Cats, ZIO and Spark to 100,000+ students at various levels. I've held live training sessions for companies including Adobe and Apple, taught university students who now work at Google and Facebook, run Hour of Code for 7-year-olds, and taught more than 50,000+ kids to code.
I have a Master's Degree in Computer Science and I wrote my Bachelor and Master thesis on Quantum Computation. Before learning programming, I won medals at international Physics competitions.
