    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
    K8s should be avoided - If your application works well without being converted into microservices-based architecture & fits correctly in a VM, needs less scaling, have a fixed traffic pattern then it is better to keep away from Kubernetes. Otherwise, the operational challenges & technical expertise will add a lot to the OPEX. Also, if you're the one who thinks that containers consume fewer resources as compared to VMs then this is not true. As soon as you convert your application to a microservice-based architecture, a lot of components will add up, shooting your resource consumption even higher than VMs so, please beware. Kubernetes is a good choice - When the application needs quick scaling, is already in microservice-based architecture, has no fixed traffic pattern, most of the employees already have desired skills.

    Pros
    Open Source
    • 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
    • Complex cluster management can be done with simple commands with strong authentication and authorization schemes
    • Exhaustive documentation and open community smoothens the learning process
    • As a user a few concepts like pod, deployment and service are sufficient to go a long way

    Cons
    Open Source
    • 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
    • Local development, Kubernetes does tend to be a bit complicated and unnecessary in environments where all development is done locally.
    • The need for add-ons, Helm is almost required when running Kubernetes. This brings a whole new tool to manage and learn before a developer can really start to use Kubernetes effectively.
    • Finicy configmap schemes. Kubernetes configmaps often have environment breaking hangups. The fail safes surrounding configmaps are sadly lacking.

    The Kubernetes is going to be highly likely renewed as the technologies that will be placed on top of it are long term as of planning. There shouldn't be any last minute changes in the adoption and I do not anticipate sudden change of the core underlying technology. It is just that the slow process of technology adoption that makes it hard to switch to something else.

    Kubernetes
    It is an eminently usable platform. However, its popularity is overshadowed by its complexity. To properly leverage the capabilities and possibilities of Kubernetes as a platform, you need to have excellent understanding of your use case, even better understanding of whether you even need Kubernetes, and if yes - be ready to invest in good engineering support for the platform itself

    Most of the required features for any orchestration tool or framework, which is provided by Kubernetes. After understanding all modules and features of the K8S, it is the best fit for us as compared with others out there.

    Return on Investment
    Open Source
    • 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.

    • Because of microservices, Kubernetes makes it easy to find the cost of each application easily.
    • Like every new technology, initially, it took more resources to educate ourselves but over a period of time, I believe it's going to be worth it.
