Java?! **[CodeHead](https://daily.dev/sources/codehead)** · 4 min read · 181 upvotes · 31 comments ## Summary Netflix leverages Java for its backend, despite its reputation as outdated or verbose. Java's performance, scalability, and mature ecosystem make it a reliable choice for Netflix's microservices. With tools like Spring Boot, Netflix efficiently manages its vast streaming services. The use of Java demonstrates the company's preference for dependable technology over trends. ## Full article daily.dev links to this article rather than hosting it.

And if Netflix can keep millions of streams running smoothly with Java + Spring Boot, then we can definitely build solid systems without chasing every hype. **@alx\_dsz** · 20 upvotes > I can't understand why this information is so shocking to people. > > I guess the dev community watches too many influencer videos hyping the next new framework or _comparing languages_ instead of serious content and books on actually engineering. **@balive053** · 6 upvotes > And so is Amazon... and Java is probably the most prevalent language across Big Tech.
