CoreOS rkt

CoreOS rkt is well suited for any development environment where operating systems and hardware are not homogeneous. CoreOS rkt allows us to write code on one machine with the confidence that it will work on any other. This has been immensely helpful as our developers are often switching to the latest and greatest machines and operating systems. CoreOS rkt is less suited for environments that are not Software as a Service. There is often no need to bring the entire developer environment and associated dependencies when delivering a one time product. In these environments CoreOS rkt just adds unneeded overhead.

Kubernetes

  1. Kubernetes is very easy to get started and to set up
  2. It has various deployment options, file systems and service types making it suitable for several use cases besides Machine Learning
  3. Extends the functionality of Docker's rich functionality making it a deadly combination
  4. The rough edges in file system, utilization and resource management should be fixed to be adopted as a standard in a company
  5. Its extremely vast Python library makes it easy to build services on top of kubernetes. However the API is quite complex and documentation is quite poor

Pros

CoreOS rkt

  • Running a secure container without messing up with low-level details
  • Very clear and straightforward approach to building a container
  • A way to go for new projects thinking of containers
  • Comprehensive and well-written documentation compatible with UNIX keep it simple way of thinking

Kubernetes

  • Cost-effectiveness, Kubernetes is free and open source.
  • Scalability, Kubernetes works regardless of how many pods it's managing; be it ten or a thousand.
  • Low overhead, Kubernetes adds very little performance cost per developer per machine. The benefits of having a managed system vastly outweigh the minor performance cost.
  • Large market share, Kubernetes is one of the top container orchestration tools used by developers today. This has been immensely helpful when finding new talent who are familiar with Kubernetes.

Cons

CoreOS rkt

  • Market share, it's often very difficult to find new talent who use CoreOS rkt.
  • Lack of wow features, CoreOS rkt doesn't necessarily offer any immediate advantages over other container solutions.

Kubernetes

  • Speed of error detection - many times, in attempting to fix a problem, I found that kubernetes just had a delay in handling an automated fix. By changing the system, I was playing a cat and mouse game with kubernetes' attempts to auto-fix the error.
  • Sensible logging - many of the logs are difficult to decipher and too verbose to be useful.
  • The learning curve is high - it took many months of working with Google, in which both I and Google Support Engineers learned a lot about how Kubernetes works. The learning curve is not for people looking for quick and easy out of the box.

Documentation for Kubernetes is better than usual, and there are a variety of paid support offerings available from a variety of consultant shops. Explicit examples for specific features are sometimes hard to come by due to the wide array of features available, and the documentation can be overwhelming. Further, without any first-party paid offering, it's sometimes hard to know who to reach out to for support.

Kubernetes

Docker Swarm is not as advanced as Kubernetes and there are no out of the box solutions for auto scaling and deployment strategies. Docker swarm doesnot have much experience with production deployments at scale. Swarm has a smaller community, and less frequent releases as compared to the very big Kubernetes Community and its rapid releases.

Return on Investment

CoreOS rkt

  • Developers spend less time configuring and more time coding.
  • Less time training developers as CoreOS rkt lets them use whatever hardware and operating system they want.
  • Reduced our IT costs, solutions are containerized using CoreOS rkt meaning they can write one solution with many developers in mind.

Kubernetes

  • We switched from Chef, so we got a HUGE amount of ROI by switching our microservices over to Kubernetes 8. A lot less code, a lot easier to test, and immutable images means we have just one build and that artifact goes through all the environments.
  • Automated deploys are SUPER easy with Kubernetes 8. We just have simple scripts listening on a GitHub repo for changes that applies/creates all the Kubernetes 8 pieces we need. Everyone has the power to deploy to any of the clusters through code and code reviews.
  • Shrunk our devops need dramatically, everything just works.
