Beyond Block and File: COSI Enables Object Storage in Kubernetes

With COSI, Kubernetes cluster users are able to manage object storage in a standardized, native way. Storage vendors are able to expose their object storage solution through COSI without ever touching Kubernetes code. Storage is able to meet current needs, and everyone wins.

Kubernetes has been invaluable in developing today’s applications. There are other options for container orchestration systems, but Kubernetes is recognized as one of the most popular and mature options. Let’s now look at the power of this system, its limitations and the innovation that has made it even more usable and beneficial.

Kubernetes: A Quick Overview

For those unfamiliar with Kubernetes, it’s an orchestration system used to deploy and manage containerized applications. In a cluster, Kubernetes ensures the running state always converges to specifications provided by application developers.

The system uses abstract “objects” to define an API. The objects are resources that developers can use to run their application (like containers and load-balancers), how many instances are desired, and where in the cluster an application is allowed to run, etc. These abstractions allow developers to focus on their application instead of the environment it will run in. It also encourages application architectures that are very portable, scalable and resilient.
