EVOLUTION OF JAVA USAGE AT NETFLIX

Summary from the TLDR Web Dev newsletter

Netflix heavily uses Java for its backend apps. It started with a microservice architecture that evolved over time to incorporate new technologies. Initially, the company employed Groovy scripts and reactive programming for tailored API responses. It has since migrated to GraphQL Federation for a unified API, removing the need for custom backend layers. Netflix uses recent Java versions for performance gains and actively uses Spring Boot.
