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.

If you use Windows, you will want to monitor Windows Events. A recent contribution of a distribution of the OpenTelemetry (OTel) Collector makes it much easier to monitor Windows Events with OpenTel. You can utilize this receiver either in conjunction with any OTel collector: including the OpenTelemetry Collector. In this article, we will be using observIQ’s distribution of the collector.

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

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.

Kubernetes is a widely used open source system for container orchestration. It allows for seamless running of containerized workloads across different environments. However, managing Kubernetes optimally can be a daunting task due to its complex architecture. Properly monitoring a Kubernetes cluster or any related environment can be difficult. Effective resource provisioning and management is a critical aspect of a Kubernetes cluster.

If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be?
