Monitor your Quarkus native application on Azure
Introduction Quarkus is a general-purpose Java framework focused on efficient use of resources, fast startup, and rapid development. It allows developers to create and run services in the Java Virtual Machine (JVM) or native binary executables (native mode). In this blog post we are going to focus on using Quarkus to create and monitor a native mode Quarkus application on Azure. A simple service will be created from scratch to demonstrate the capability of sending OpenTelemetry data to Azure. Why native? Quarkus Native Mode refers to building and running a Quarkus application as a native binary executab...
Jakarta EE and Quarkus on Azure – June 2025
Hi everyone, welcome to the June 2025 update for Jakarta EE and Quarkus on Azure. It covers topics such as DevServices support of Quarkus Azure Extension, and comprehensive guides on implementing Quarkus applications monitoring and Liberty applications monitoring. If you're interested in providing feedback or collaborating on migrating Java workloads to Azure with the engineering team developing Jakarta EE and MicroProfile on Azure solutions, please complete this short survey on Jakarta EE migration. The team of product managers, architects, and engineers will promptly get in touch with you to initiate close col...
Announcing Azure Command Launcher for Java
Optimizing JVM Configuration for Azure Deployments Tuning the Java Virtual Machine (JVM) for cloud deployments is notoriously challenging. Over 30% of developers tend to deploy Java workloads with no JVM configuration at all, therefore relying on the default settings of the HotSpot JVM. The default settings in OpenJDK are intentionally conservative, designed to work across a wide range of environments and scenarios. However, these defaults often lead to suboptimal resource utilization in cloud-based deployments, where memory and CPU tend to be dedicated for application workloads (use of containers and VMs) but s...

The State of Coding the Future with Java and AI – May 2025
Software development is changing fast, and Java developers are right in the middle of it - especially when it comes to using Artificial Intelligence (AI) in their apps. This report brings together feedback from 647 Java professionals to show where things stand and what is possible as Java and AI come together. One of the biggest takeaways is this: Java developers do not need to be experts in AI, machine learning, or Python. With tools like the Model Context Protocol (MCP) Java SDK, Spring AI, and LangChain4j, they can start adding smart features to their apps using the skills they already have. Whether it ...
Important Updates to Container Images of Microsoft Build of OpenJDK
Mariner Linux 2.0 will reach its End-Of-Life (EOL) in July of 2025 and will be replaced with Azure Linux (version 3.0). To ensure a smooth transition for our customers and partners, the Java Engineering Group (DevDiv JEG) behind the Microsoft Build of OpenJDK has developed a migration aligned with this timeline. This strategy takes effect on June 30, 2025, coinciding with the official EOL date for Mariner Linux 2.0. Our Strategy This way we can ensure a reasonable balance between security by default and alternatives for our customers who need to roll back to previous versions despite...
