By Jennifer Shin , Tejas Shikhare , Will Emmanuel In 2022, a major change was made to Netflix’s iOS and Android applications. We migrated Netflix’s mobile apps to GraphQL with zero downtime, which involved a total overhaul from the client to the API layer. Until recently, an internal API framework, Falcor , powered our mobile apps. They are now backed by Federated GraphQL , a distributed approach to APIs where domain teams can independently manage and own specific sections of the API.

Applications nowadays are distributed as microservices all over the cloud. Organizations use Kubernetes to manage these applications at scale, which has brought great flexibility and agility for development teams. However, microservices and multicloud applications have given rise to new challenges. Now, it is harder to configure communication between distributed services and secure the data in transit.

It answered correctly that the number was non-prime, but when it told me the number’s prime factors, it was clearly wrong. It also generated a short program that implemented the widely used Miller-Rabin primality test.
