Docker vs. SUSE Rancher

You are going to be able to find the most resources and examples using Docker whenever you are working with a container orchestration software like Kubernetes. There will always some entropy when you run in a container, a containerized application will never be as purely performant as an app running directly on the OS. However, in most scenarios this loss will be negligible to the time saved in deployment, monitoring, etc.

SUSE Rancher as a management tool becomes useful on a larger scale. Small deployments not so much. If someone also requires Kubernetes capacity or storage, Rancher is an excellent choice. Also, without Kubernetes' skills, it is unlikely that Rancher deployment is going to be a success. Then again if someone else is managing your Kubernetes capacity, setting up the software's capacity will yield greater control. Rancher is not a very integrated solution similar to others in the market.

• Packaging of application to limit the space occupied
• Ease of running the application
• Provide multiple ways to handle the application issues and integration of different components like pipeline, ansible, terraform etc

• Public and private cloud infrastructure providers based on K8s CAPI
• REST API that can be used to integrate company services with Rancher
• GUI that is easy to learn and use in daily operations
• Builtin GitOps automation solution based on Fleet project
• It is fully open source

• Docker hub image retention policy can be relaxed
• Docker hub policies can be more developer friendly
• Docker CLI help section can be improved
• Image and container storage (local) management can be optimized

• No possibility to snapshot Projects. You can snapshot and restore the whole Kubernetes cluster, but not a Project or Namespace. For this, you have to use external tools.
• You cannot detach the Rancher-created Kubernetes clusters from Rancher management.

I have been using Docker for more than 3 years and it really simplifies the modern application development and deployment. I like the ability of Docker to improve efficiency, portability and scalability for developers and operations teams. Another reason for giving this rating is because Docker integrates CI/CD pipelines very well

Overall it deserves an 8 out of 10. The platform is very easy to use as long as the UI is stable. We have had a few buggy versions in the past. However the CLI is excellent and the platform is simple to manage and maintain. It is easy to deploy and offer for company wide use which increases utilization and ROI.

Haven't seen any outages, fatal/unrecoverable errors in my usage so far. Enough said.

Docker Desktop. The CPU high usage is a known issue. Needs fixing. Otherwise, it is great overall. Would not use anything else still.

The documentation is quite complete and there is a very active community that is willing to collaborate and answer questions for those who are just starting out.

The reason why we are still using Docker right now is due to that is the best among its peers and suits our needs the best. However, the trend we foresee for the future might indicate Amazon lambda could potentially fit our needs to code enviornmentless in the near future.

We started using SUSE Rancher in the early days and spent a large amount of time getting to know and love it. This was before the days of some of the likes of Amazon Web Services who may now provide a cheaper but less feature-rich alternative to SUSE Rancher, however we have yet to explore this.

The investment for small environments is quite significant. There has to be a compelling case to enhance the areas where SUSE Rancher brings in value to make such a financial leap. There is also a free version to test the value propositions, which will help support the user's buying decisions. More clusters, more volume, more tasks and more complexity in the environment equals more value that Rancher can provide.

It is the only tool in our toolset that has not [had] any issues so far. That is really a mark of reliability, and it's a testimony to how well the product is made, and a tool that does its job well is a tool well worth having. It is the base tool that I would say any organisation must have if they do scalable deployment.

• Reduces the number of virtual machine which impacted our quarterly billing
• Using docker with proxy we run multiple application on same port on same host.
• impact on billing is we have to provide docker training to the people who are working on it.

• Shortens "Time-to-Market" factor for new business applications or implementing new functionalities. From 1 to 50 microservices-based business applications in 6 years.
• 24/7 availability, generates more money. There are many infrastructure components that are regularly powered-off for maintenance or upgrade, bur we rarely are turning off our downstream Kubernetes clusters where our business applications lives.
• Single Point of Contact with platform maintenance and development Team, eases implementation of new business applications
