OpenStack vs Rancher: What are the differences?
Developers describe OpenStack as "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. On the other hand, Rancher is detailed as "Open Source Platform for Running a Private Container Service". Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
OpenStack belongs to "Open Source Cloud" category of the tech stack, while Rancher can be primarily classified under "Container Tools".
Some of the features offered by OpenStack are:
On the other hand, Rancher provides the following key features:
- Manage Hosts, Deploy Containers, Monitor Resources
- User Management & Collaboration
- Native Docker APIs & Tools
"Private cloud" is the top reason why over 35 developers like OpenStack, while over 89 developers mention "Easy to use" as the leading cause for choosing Rancher.
Rancher is an open source tool with 11.9K GitHub stars and 1.34K GitHub forks. Here's a link to Rancher's open source repository on GitHub.
According to the StackShare community, Rancher has a broader approval, being mentioned in 89 company stacks & 35 developers stacks; compared to OpenStack, which is listed in 67 company stacks and 50 developer stacks.

- Consume too much unnecessary resource by just running rancher agent alone;
- Hard to recover from system failure
- Bad performance of load balancing (compare to dokcer swarm built-in LB or others).
The whole infrastructure is managed through Rancher. It provides a simple interface to all the underlying tools - Docker, HAProxy (automatically configures load balancer from the containers).
IaaS for our core private cloud, and with AWS, HP Helion, and Rackspace to burst to public clouds to create a multi-sourced hybrid cloud setup.
Currently looking to move to Swarm or Kubernetes due to a few issues I have with Rancher.
