How to Prevent Reactive Java Applications from Stalling
Modern applications must work smoothly on high loads and with a high number of concurrent users. Traditional Java applications run blocking code and a common approach for scaling is to increase the number of available threads. When latency comes into the picture, many of these additional threads sit idle, wasting resources. A different approach increases efficiency by writing asynchronous non-blocking code that lets the execution switch to another task while the asynchronous process completes. Project...
Build Spring Microservices and Dockerize Them for Production
In this post, you’ll learn about microservices architecture and how to implement it using Spring Boot. After creating some projects with the technique, you will deploy the artifacts as Docker containers and will simulate a container orchestrator (such as Kubernetes) using Docker Compose for simplification. The icing on the cake will be authentication integration using Spring Profiles; you will see how to enable it with a production profile. But first, let’s talk about microservices. Understand...
Spring Boot 2.1: Outstanding OIDC, OAuth 2.0, and Reactive API Support
Spring Boot 2.1 was recently released, eight months after the huge launch of Spring Boot 2.0. The reason I’m most excited about Spring Boot 2.1 to me is its improved performance and OpenID Connect (OIDC) support from Spring Security 5.1. The combination of Spring Boot and Spring Security has provided excellent OAuth 2.0 support for years, and making OIDC a first-class citizen simplifies its configuration quite a bit. For those that aren’t aware, OIDC is...
