Bytebytego How Netflix Really Uses Java Paul bakker discusses netflix’s use of java, emphasizing the use of microservices, rxjava, hystrix and spring cloud. Netflix’s java architecture in 2025 isn’t a relic of the past, but a deliberate, modern engineering system. what makes it interesting isn’t the choice of language, but the way that choice is continuously reevaluated, optimized, and aligned with real world constraints. In this post, we will look at the evolution of java usage at netflix in light of the overall architectural changes that have taken place to support the changing requirements. The java stack has significantly evolved alongside netflix's architectural changes to meet evolving requirements. all backend applications at netflix are java based, covering internal tools, studio software, and the netflix streaming app.

Mobile and web: netflix has adopted swift and kotlin to build native mobile apps. for its web application, it uses react. frontend server communication: netflix uses graphql. backend services: netflix relies on zuul, eureka, the spring boot framework, and other technologies. Netflix engineer, paul bakker, discussed netflix's use of java and its evolving architecture. they have a plethora of java applications and are moving towards graphql federation. Here’s how it really works. when you click “play” on netflix, you initiate a series of operations that span continents, data centers, and thousands of microservices. netflix isn’t just a streaming platform; it’s a distributed engineering marvel serving over 270 million users across the globe.
