PlanetScale has deployed millions of Amazon Elastic Block Store (EBS) volumes across the world. We create and destroy tens of thousands of them every day as we stand up databases for customers, take backups, and test our systems end-to-end. Through this experience, we have an unique viewpoint into the failure rate and mechanisms of EBS, and have spent a lot of time working on how to mitigate them.

ttyd is a simple command-line tool for sharing terminal over the web.

At Mercado Libre, managing over 30,000 microservices and supporting 16,000 developers requires a robust and scalable solution. To address these challenges, we adopted Kubernetes (K8s) as the core engine of our internal platform, Fury. This article explores how Kubernetes streamlined our infrastructure management, accelerated software delivery, and improved cost efficiency, enabling our developers to focus on innovation and product creation.

TL;DR Istio proxy costs for 10-nodes GKE cluster reduced from $3065 to $185 per month.

Kubernetes RBAC has some tricky areas where the behaviour you get might not be exactly what you expect, and sometimes as in this case, those unexpected behaviours are not very apparent!

In this article I will explain how you can safely fail over a rook-ceph Monitor to a new Kubernetes node.

I hope I will save you some time and if you find the content useful please leave a clap.Also let me know in the comments of the article if you need professional help with a common topic.

container-startup-autoscaler (CSA) is a Kubernetes controller that modifies the CPU and/or memory resources of containers depending on whether they're starting up, according to the startup/post-startup settings you supply. CSA works at the pod level and is agnostic to how the pod is managed; it works with deployments, statefulsets, daemonsets and other workload management APIs.

We all can agree that the most important purpose of a post-incident review (or post-mortem) is to learn from incidents. Implied in this learning is improving the system (people, processes, technology, and their interactions). All my reflections on the “5 Whys” technique refer back to how the technique enhances our learning (or not) from incidents.

Some thinking, trade-offs, theory building, and method-making one might ended up doing, in the course of bringing Infrastructure as Code (IaC) discipline to brownfield (and greenfield) services, at a small regulated fintech company, having a smaller engineering team that serves several business units, including one of India's largest national tax gateways. Only somewhat easier than reading a long compound sentence without pausing for breath. Phew.
