Still Running Java the Old Way? Here's Why OCI Changes Everything

Java on OCI: Performance, Security, and Advanced Management

Recently, I had the opportunity to present at Oracle about the benefits of running Java workloads on Oracle Cloud Infrastructure (OCI).

Java has evolved significantly over the years, and when combined with OCI, it offers a range of advantages for developers and businesses looking for high performance, security, and simplified management.

Here are some of the key points I covered in my presentation:

1. Java LTS and Continuous Updates

Java provides Long-Term Support (LTS) versions, receiving quarterly security patches and semi-annual feature updates, ensuring that applications running on OCI remain secure and optimized.

2. Java Management Service (JMS)

The Java Management Service is a powerful tool that operates across three key areas:

• Discovery: Automatically inventories Java applications on specified machines.
• Manage: Enables runtime management directly from the OCI console, allowing for easy installation, removal, and updates.
• Insights: Generates reports on JDK version migrations, assessing the effort required and identifying necessary code changes. It also provides security and performance analyses, detecting bottlenecks using Java Flight Recorder.

3. GraalVM: The Java Performance Revolution

GraalVM is a game-changer in Java optimization, offering two compilation modes:

• JIT (Just-In-Time): Adapts in real-time, undergoing a "warmup" phase.
• AOT (Ahead-Of-Time): Produces a native image, fully compiled to machine code, eliminating the need for a JVM. This can accelerate application startup by up to 100x.

Imagine a container that typically takes 2 minutes to start, with native image, it could be up and running in seconds! But performance isn’t just about AOT; GraalVM’s JIT is already more optimized than the traditional JDK, offering a 25% performance boost just by switching from the standard JDK to GraalVM JDK.

4. Java EPP: The Best of Both Worlds

For workloads that cannot yet migrate from Java 8 but still need the benefits of newer JVM versions, Enterprise Performance Pack (EPP) is the perfect solution. It allows applications to run with the JVM from Java 17 without requiring code refactoring, delivering better performance and security.

All These Benefits, Just by Running Java on OCI!

If your company uses Java, running it on OCI can take your applications to the next level in performance, security, and intelligent management.
