Migrating Java applications to the cloud
Java is a popular framework that’s been a foundation for many enterprise applications for over 20 years. But lately, those enterprises have run into trouble: moving their applications to the cloud. This migration promises more security, reliability, and easier scaling, but it can be daunting with an older framework like Java. The host, @robertdouglass of Platform.sh, asks,
“With all these older versions of applications floating around in this huge plethora of runtimes and variants, does that make it harder for organizations to “lift and shift”, or to adopt cloud native philosophies?”
Speakers from Red Hat, the Eclipse Foundation, and Paerra address the Java toolbox that can help ease this transition.
Java toolbox for developers
- Jlink -- A command-line utility which helps modularize your application and makes it possible to build your own JVM
- Graal.vm -- A compiler that helps existing Java applications run faster, provide extensibility with scripting languages, and create ahead-of-time or just-in-time compiled native images
- Transformer -- An Eclipse project that takes your application to the Jakarta EE namespace so you don’t have to recompile
- Jakarta EE --The new name and face of Java EE, with all the same benefits: maturity, reliability, stability, and large community. Jakarta EE is a more enterprise-ready, cloud-ready, and microservice-ready version of Java.
What should hype up developers about working with Jakarta EE? Ivar Grimstad of the Eclipse Foundation says, “If you want to be future-proof and to be productive right away, you can write less code, less configuration, and less boilerplate to get up and running using Jakarta EE than any other framework.”
Make your life easier with Java tools
Launching Java-built applications to the cloud can be difficult, but developers can minimize bumps by putting tools like Jlink, Graal.vm, Transformer, and Jakarta EE to work. Robert Douglass sums it up: “Stability, backwards compatibility, safety, and boringness are the hallmarks of the Java ecosystem these days, and they are really attractive features when the very act of software development is so fraught with risk.”
