Track Overview

Evolving Java

The Java is Dead meme continues in 2020, 10 years after it started!  Unsurprisingly enough, the Java ecosystem just keeps evolving, with new innovations that continue to drive large enterprises, cloud infrastructure and has Trillion's of dollars worth of commercial activity run on it each year.  This year at QCon we look at the important innovations in the Java space that will directly impact you in the short term future.  

There has been a number of innovations around running Java in a Cloud Native environment. Quarkus is a leading light here, allowing you to build and deploy native image applications that are Java-compatible. Deploying Java applications efficiently on Docker was a struggle 5 years ago, but now Java is a leader in language support for containers and we look at the latest work to optimize this even further.  The global migration from Java 8 to 11 is finally taking place, and major enterprises are now planning their move, we bring you a field report by one of the world's most exciting digital banks! Looking a little further forward we finally have a working implementation of Records and Sealed Types that you can use to build more efficient data structures. Lastly, for the bold, there's a new Java compiler in town called Graal that some claim has massive performance benefits. But how does Graal really execute code, as compared to Hotspot today, that question is answered in this track before you take the plunge!"

How the HotSpot and Graal JVMs execute Java Code

When Java was released in 1995 it was slow, a reputation it has carried for many years… Today Java can give performance that is comparable to C++ and can emit instructions that are more optimal than code which is statically compiled. But how?  This talk will explore practical examples...

Java in Containers - Part Deux

Containers are everywhere in modern cloud workloads, but that doesn’t mean everything's roses! Container isolation imposes a de-facto additional complexity layer, i.e. a virtual machine, and running unprivileged containers is not a simple task. How do containers affect the ergonomics of...
