Yes, you can run VMs on Kubernetes with KubeVirt

Containers and Kubernetes are awesome technologies that enable applications to run without a heavy operating system (OS), as using a virtual machine (VM) would require. Container-first, cloud-native applications are the future, but not every application is suitable to be cloud-native. KubeVirt allows you to run your virtual machines alongside your containers on a Kubernetes platform.

Our users were also accustomed to a certain SLA standard — a 2-second page load time could have been acceptable a few years ago, but waiting more than a second for an Instagram post is unthinkable nowadays. When systems get more complex, with strict latency requirements and a distributed infrastructure, an uninvited guest crawls up our systems — request failure.

Keeping sync fast with automated performance regression detection

Sync is a hard distributed systems problem and re-writing the heart of our sync engine on the desktop client was a monumental effort. We’ve previously discussed our efforts to heavily test durability at different layers of the system. Today, we are going to talk about how we ensured the performance of our new sync engine.

Production testing with dark canaries

Back in 2013, one of our large backend services wanted support in Rest.li for dark canaries. The service, at the time, involved duplicating requests from one host machine and sending it to another host machine. This was added via a Python tool to populate the host-to-host mapping in Apache ZooKeeper along with a filter to read this mapping and multiply traffic.
