Posted on November 2, 2023, Level intermediate Resource Length medium
We'll take a look at how we wire (most of) it up. In particular, we'll go over the role of the Platform.sh edge layer, and describe in detail how we network hosts and containers together. From the networking perspective, our job is to make sure that a request directed towards your web server reaches the right container, and that container is able to communicate with other containers that your hosted application depends upon, all while making sure that someone else's container cannot talk to one of your containers.

How Grafana Labs uses and contributes to OpenCost, open source project for real-time cost monitoring in Kubernetes
Posted on February 10, 2023, Level beginner Resource Length medium
While more and more teams are adopting Kubernetes as their standard container orchestration technology, cost insight is lacking. Teams often don't know how much they're spending, where in their organization they are spending, or what is driving their infrastructure cost increases. OpenCost helps alleviate this problem by bringing real-time cost monitoring to Kubernetes workloads with a solution that encompasses both an open specification and an open source project.
