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.

Kubernetes adoption survey executive summary. Modern, cloud-native computing is impossible to separate from containers and Kubernetes adoption. While Kubernetes is still a relatively young technology, a large majority of global enterprises use it to run business-critical applications in production. The rapid adoption is driven—and challenged by—an ever-growing ecosystem of Kubernetes technologies that add advanced platform features, such as security, microservice communications, observability, s

“Set it and forget it” is the approach that most network teams follow with their authoritative Domain Name System (DNS). If the system is working and end-users find network connections to revenue-generating applications, services, and content, then administrators will generally say that you shouldn’t mess with success. Unfortunately, the reliability of DNS often causes us to take it for granted.

What Is Distributed Tracing? The rise of microservices has enabled users to create distributed applications that consist of modular services rather than a single functional unit. This modularity makes testing and deployment easier while preventing a single point of failure with the application. While applications begin to scale and distribute their resources amongst multiple cloud-native services, tracing a single transaction becomes tedious and nearly impossible.

Docker is a containerization technology that allows developers to package and deploy applications in lightweight, portable containers. These containers are isolated from the host operating system, which makes them portable across different environments and eliminates the “works on my machine” problem. Docker is a popular platform for creating and managing containerized applications; however, several alternatives for Docker can also be used for this purpose.

As teams moved their deployment infrastructure to containers, monitoring and logging methods changed a lot. Storing logs in containers or VMs just doesn’t make sense – they’re both way too ephemeral for that. This is where solutions like Kubernetes DaemonSet come in. Since pods are ephemeral as well, managing Kubernetes logs is challenging. That’s why it makes sense to collect logs from every node and send them to some sort of central location outside the Kubernetes cluster for persistence and l
