In this conversation, Jim Grisanzio from Java Developer Relations talks with Paul Bakker, an engineer and Java architect in California. Paul is a staff software engineer in the Java Platform team at Netflix. He works on improving the Java stack and tooling used by all Netflix microservices and was one of the original authors of the DGS (GraphQL) Framework. He is also a Java Champion, he's published two books about Java modularity, and he's a speaker at conferences and Java User Groups.

Java Is Everywhere at Netflix

Paul will present "How Netflix Uses Java: 2026 Edition" at JavaOne in March. The session updates previous year's talk because Java keeps evolving at Netflix. "Netflix is really staying on the latest and greatest with a lot of things," Paul says. "We're trying new things. And that means there's always new stuff to learn every year."

Java powers both Netflix streaming and enterprise applications used internally and supporting studio teams. "Java is everywhere at Netflix," Paul says. "All the backends, they are all Java powered." Why Java? It comes down to history and practicality. The original team members were Java experts, but more importantly, "Java is also just the best choice for us," he says. The language balances developer productivity and runtime performance. At Netflix's scale with thousands of AWS instances running production services, runtime performance is critical.

Netflix engineers stay closely connected with development at OpenJDK. They test new features early and work with preview releases or builds before official releases. When virtual threads appeared, Netflix engineers tested immediately to measure performance gains. Paul says they give feedback on what works, what doesn't work, and what they would like to see different. This just demonstrates the value of being involved with OpenJDK, and Paul says they have a really nice back and forward with the Oracle engineering teams.

The microservices architecture Netflix adopted years ago enabled the company to scale. This approach has become common now, but Netflix pioneered talking about it publicly. Breaking functionality into smaller pieces lets teams scale and develop services independently. Most wor
