Write a Kubernetes-ready service from zero step-by-step #k8s

Sun, 17 Dec 2017 19:48:00 +0000

If you have ever tried Go, you probably know that writing services with Go is an easy thing. Yes, we really need only few lines to be able to run http service. But what do we need to add if we want to prepare our service for production? Let’s discuss it by an example of a service which is ready to be run in Kubernetes.

Introducing conduit - a service mesh for kubernetes #k8s

Tue, 05 Dec 2017 16:14:00 +0000

Today, we’re very happy to introduce Conduit, our new open source service mesh for Kubernetes.

We’ve built Conduit from the ground up to be the fastest, lightest, simplest, and most secure service mesh in the world. It features an incredibly fast and safe data plane written in Rust, a simple yet powerful control plane written in Go, and a design that’s focused on performance, security, and usability. Most importantly, Conduit incorporates the many lessons we’ve learned from over 18 months of production service mesh experience with Linkerd.
