Queue-Based Load Leveling Pattern (Starring Phi4, LangChain4j and Azure Service Bus)
In this blog, we’re exploring the Queue-Based Load Leveling pattern—a powerful method for smoothing out workload spikes Why Choose Queue-Based Load Leveling? In today's fast-paced software environment, dynamic workloads are common. The Queue-Based Load Leveling pattern decouples the production and consumption of tasks by introducing a queue between them. This allows producers and consumers to work independently, preventing system overload during traffic spikes. For small, monolithic applications, in-memory queues might suffice. However, as applications scale or adopt distributed architectures, these simple...

MWA pattern: Strangler Fig
Author’s Note: After announcing the Modern Web App (MWA) pattern (https://devblogs.microsoft.com/java/introducing-the-modern-web-app-mwa-pattern-for-java), we now focus on one of its many pattens - the Strangler Fig pattern. This pattern incrementally modernizes a legacy Java application by “strangling” targeted areas and replacing them with new microservices or minimal web apps. We’ll explore an example showing how to integrate this approach and smoothly transition from a monolith to modern microservices. MWA pattern: Strangler Fig Introduction In today's fast-paced technological landscape, modern...

Announcing Javac support in Visual Studio Code Java
Hi everyone, we are pleased to announce partial support of Javac as the underlying compiler in Visual Studio Code Java, JDT, and JDT-LS. The effort to provide this support has been a joint collaboration with Red Hat and Microsoft and is nearly a year in the making. This change aims to ensure timely support for the latest Java features and align Java language support on VS Code more closely with common build tools (such as Maven, Gradle). Many of our users have shared the desire for a more seamless, out-of-the-box development experience, and we believe introducing Javac is a strong first step toward making that...
