Why Spring Teams Don't Need a Second Runtime for AI Agents

Wed, 10 Jun 2026 19:02:58 +0000

A JVM-native runtime for building, governing and operating AI agents on existing Spring infrastructure.

Every time a Spring team decides to add AI agents to a production system, the story tends to follow the same arc. A few prototypes are built, several frameworks are evaluated, and then a new reality emerges: the project is no longer just about adding agents. It is about operating a new platform.

With that new runtime come new deployment pipelines, new monitoring mechanisms, additional security reviews, and new operational responsibilities.

AWS Nitro and CPU Graviton Meets Unikernels

AWS Nitro and CPU Graviton Meets Unikernels: Java and Quarkus on ARM64 AWS Graviton with Nanos Unikernel

Java and Jakarta EE Truly Meet Unikernels

The key message of this article is simple and strong:

any Java or Jakarta EE application is already ready to benefit from the advantages of unikernels.

Java and Jakarta EE, including modern frameworks such as Quarkus, can immediately take advantage of the unikernel model without waiting for new languages, new runtimes, or radical rewrites.

Sustainable Software Engineering: Input Requested!

Wed, 21 Aug 2024 09:49:20 +0000

The Foojay community has a strong tradition around the creation of content on all things Java and OpenJDK. Since about a year ago, the community has a group of people that are working on a book with tips and information on Sustainable Software Engineering. For some of the topics in the book, we are looking for data to either support claims that are made, or inform us on the best direction to write a topic.

Achieving High Throughput Without Sacrificing Latency

Fri, 02 Feb 2024 09:39:47 +0000

Latency and Throughput

In discussions on performance, it is common to encounter the terms Latency and Throughput to describe the characteristics of a software component.

We can define these terms as follows:

Latency is a measure of the time taken for one thing to occur. For example, it could be the time taken to respond to a change in the price of a financial instrument that could influence the decision on whether to buy, or sell. It could be the time taken for a component monitoring some external device to respond to an indication of a change in the status of that device (like a change in temperature reported from a thermometer).

Foojay Podcast #38: Java in the Cloud

Mon, 25 Dec 2023 12:02:46 +0000

Java was born in 1995, when the internet as we know it today didn’t exist yet.

Cloud servers, Docker, Kubernetes, distributed systems, scaling up and down… these things are now part of our daily job, but Java wasn’t originally designed for it.

In this episode, we want to learn if the recent evolutions in OpenJDK, and ongoing related projects, will make Java a full Cloud member.

State of Java Survey

Tue, 23 May 2023 05:47:41 +0000

Do you ever wonder what OpenJDK distributions and what Java versions your peers are using? Java-based infrastructures and languages? How many are running Java applications in public clouds?

THE SURVEY DESCRIBED BELOW IS NOW COMPLETE, NO MORE RESPONSES CAN BE ACCEPTED.

Azul has been gathering all that data from a survey of Java users, running until 6:30pm CT on June 15, 2023. If you want to participate, the survey takes about 10 minutes, and we’ll hook you up with the report after the survey is complete. Plus you’ll be helping to add to our collective knowledge. Plus you’ll be entered into a drawing to win prizes like an Apple MacBook Pro laptop or a set of AirPods.
