Kubernetes vs OpenStack: What are the differences?
What is Kubernetes? Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops. Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
What is OpenStack? Open source software for building private and public clouds. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.
Kubernetes and OpenStack are primarily classified as "Container" and "Open Source Cloud" tools respectively.
Some of the features offered by Kubernetes are:
- Lightweight, simple and accessible
- Built for a multi-cloud world, public, private or hybrid
- Highly modular, designed so that all of its components are easily swappable
On the other hand, OpenStack provides the following key features:
"Leading docker container management solution" is the primary reason why developers consider Kubernetes over the competitors, whereas "Private cloud" was stated as the key factor in picking OpenStack.
Kubernetes is an open source tool with 55K GitHub stars and 19.1K GitHub forks. Here's a link to Kubernetes's open source repository on GitHub.
Google, Slack, and Shopify are some of the popular companies that use Kubernetes, whereas OpenStack is used by PayPal, HubSpot, and Wikipedia. Kubernetes has a broader approval, being mentioned in 1046 company stacks & 1096 developers stacks; compared to OpenStack, which is listed in 67 company stacks and 50 developer stacks.
