The true cost of Kubernetes: People, Time and Productivity

While writing a comparison of Kubernetes and Koyeb, we tried to determine how much operating a Kubernetes cluster really costs. This section of our comparison took us hours to write and ended up being so long that we decided to write a dedicated post about it. Kubernetes is a proven technology, but the true cost is often underestimated: this post investigates the actual financial costs of using Kubernetes.

Building a Multi-Region Service Mesh with Kuma/Envoy, Anycast BGP, and mTLS

We recently wrote about how the Koyeb Serverless Engine runs microVMS to host your Services but we skipped a big subject: Global Networking. This is a deep dive to understand the life of an end user's request for a service hosted on Koyeb. We explore the technology and components that make up our internal architecture by following the journey of a request from an end-user, through Koyeb's Global Edge Network, and to the application running in one of our Core locations.
