Much of the chatter about GenAI is writing new code, but that's a small part of our work. Adam Tornhill talks to me and my Thoughtworks colleagues about how AI can help with refactoring.

Netflix is one of such OTT use case, which is universally followed for learning’s: one of aspect I am presenting here, Netflix’s use of Java!

Netflix is predominantly a Java shop.

Every backend application (including internal apps, streaming, and movie production apps) at Netflix is a Java application. 

However, the Java stack is not static and has gone through multiple iterations over the years.

Here are the details of those iterations:

1 - API Gateway
Netflix follows a microservices architecture. Every piece of functionality and data is owned by a microservice built using Java (initially version 8)

This means that rendering one screen (such as the List of List of Movies or LOLOMO) involved fetching data from 10s of microservices. But making all these calls from the client created a performance problem.

Netflix initially used the API Gateway pattern using Zuul to handle the orchestration.

2 - BFFs with Groovy & RxJava
Using a single gateway for multiple clients was a problem for Netflix because each client (such as TV, mobile apps, or web browser) had subtle differences.

To handle this, Netflix used the Backend-for-Frontend (BFF) pattern. Zuul was moved to the role of a proxy

In this pattern, every frontend or UI gets its own mini backend that performs the request fanout and orchestration for multiple services.

The BFFs were built using Groovy scripts and the service fanout was done using RxJava for thread management.

3 - GraphQL Federation
The Groovy and RxJava approach required more work from the UI developers in creating the Groovy scripts. Also, reactive programming is generally hard.

Recently, Netflix moved to GraphQL Federation. With GraphQL, a client can specify exactly what set of fields it needs, thereby solving the problem of overfetching and underfetching with REST APIs.

The GraphQL Federation takes care of calling the necessary microservices to fetch the data. 

These microservices are called Domain Graph Service (DGS) and are built using Java 17, Spring Boot 3, and Spring Boot Netflix OSS packages. The move from Java 8 to Java 17 resulted in 20% CPU gains.

More recently, Netflix has started to migrate to Java 21 to take advantage of features like virtual threads.

"Now I'm a pretty lazy person and am prepared to work quite hard in order to avoid work." Martin Fowler #refactoring #softwareengineering #softwarearchitecture

Önceden bahsettiğim, veterinerimizin "artık yurtdışına kod yazacağım, zaten kodun tamamını bilmem gerekmiyormuş, belli bir kısmını yapsam yetiyormuş" tadındaki fikirlerine, mikroservis mimariler ile çakışan nokta atış, bu taze kitaptan geliyor;
"Beyond the choice of technology and the signal that sends, there is the actual experience of working as a developer using this architecture. The clear separation of a microservice architecture into different domains can mean that it is easier for a new developer to get up to speed, because they don’t need to understand the whole system, just the part they are working on. That goes for supporting the application too. It should take much less time to learn how to support a small application than the whole of a monolith."
