Docker Datacenter vs Rancher: What are the differences?
Developers describe Docker Datacenter as "Develop and manage apps at any scale". Docker Datacenter is an integrated solution including open source and commercial software, the integrations between them, full Docker API support, validated configurations and commercial support for your Docker Datacenter environment. 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.
Docker Datacenter and Rancher are primarily classified as "Containers as a Service" and "Container" tools respectively.
Rancher is an open source tool with 11.8K GitHub stars and 1.31K GitHub forks. Here's a link to Rancher's open source repository on GitHub.

- 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).
Currently looking to move to Swarm or Kubernetes due to a few issues I have with Rancher.
We use Rancher for container orchestration and automated deployment pipelines.
