Foojay Podcast #55: Embedded Java, Part 2

Mon, 01 Jul 2024 08:21:42 +0000

As a backend developer, you may not realize that Java was initially born on embedded devices like set-top boxes and gateways. We discussed this topic for the first time almost three years ago in Foojay Podcast #2 with James Gosling, Johan Vos, Erik Costlow, and Frank Delporte .

In this episode #55, we look into the history of the Java Micro Edition and how things evolved. Nowadays, with processors becoming increasingly powerful, we can run the exact same Java runtime on any Linux system, from the biggest cloud servers to the smallest Raspberry Pi Zero.

Reduce Java Application Startup and Warmup Times with CRaC

Tue, 16 May 2023 11:21:12 +0000

When a Java application runs, the JVM goes through the process of loading, initializing, and optimizing the code used by the application, including libraries, frameworks, and other components to reach the optimal performance level.

Each time the application restarts, it has no record or memory of previous times it has run and the work it performed.

As a result, it has to restart, extending valuable startup and warmup times and using precious resources.

Azul Provides the CRaC in AWS SnapStart Builds

At Azul, we are very excited about the Amazon Web Services launch of SnapStart for Lambdas .

SnapStart is based on the CRaC (Coordinated Restore at Checkpoint) API developed in OpenJDK, which was originated and led by Azul.

What is the CRaC API?

The CRaC API provides a common way for Java applications to coordinate with underlying checkpoint/restore mechanisms, allowing Java code to work seamlessly and portably across various checkpoint/restore mechanisms as they become available.
