admin 2 weeks ago in

In 2019 I published a blog: Kubernetes Storage Performance Comparison. My goal was to evaluate the most common storage solutions available for Kubernetes and perform basic performance testing. I had results for GlusterFS, CEPH, Portworx and OpenEBS (with cStor backend). This blog has been popular and I received a lot of positive feedback. I’ve decided to come back with few updates on progress in the…

At Lyft, we chose to move our server infrastructure onto Kubernetes, a distributed container orchestration system in order to take advantage of automation, have a solid platform we can build upon, and lower overall cost with efficiency gains. Distributed systems can be difficult to reason about and understand, and Kubernetes is no exception. Despite the many benefits of Kubernetes, we discovered several pain points while…
