Docker vs. Mirantis OpenStack for Kubernetes

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.

Mirantis is well suited for someone who doesn't mind spending money but doesn't quite want to commit to a cloud provider like AWS. It is also well suited for small or junior technical teams that don't have the skills, experience, or time to run their own openstack clusters.

• 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

• Can be deployed and run on bare metal on premises clouds
• Is highly reliable and highly scalable
• One of the good performance private cloud IAAS platforms available around

Incentivized

• 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

• Mirantis OpenStack managed services are expensive. Very expensive for a start-up.
• I'd personally like to see a little more under the hood details in the status pages.
• Mirantis could also benefit heavily from a free "light" version that start-ups could use to run their own cloud. Maybe coupled with advertising or some sort of surveys.

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

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 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.

Mirantis OpenStack for Kubernetes is easily manageable and has seamlessly configurable containers. It also has high reliability and security, which is certainly a positive point for this product. Overall I think it is a worthy competitor in the market to compare for your needs.

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.

• Mirantis did help our business figure out if openstack was right for us.
• Using Mirantis I felt a bit cheated on understanding the deep technical knowledge of how openstack works. But that being said that is probably a value add more than a detractor for most people.
• Using Mirantis was considerably cheaper than AWS.
