    KVM is the best solution in the case you need to test and turn up any virtual environment with limited vCPU/RAM resources. The obvious area of its use is a network environment when we want to avoid being tied to one type of hardware/vendor and being able to swap from one instance to another with no downtimes. The use of a vSwitch (that supports VLAN tagging) is a significant bonus for network engineers that some other hypervisors do not provide.

    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
    Red Hat
    • KVM is really good at providing fast and reliable virtualization for Linux guests
    • Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
    • KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well

    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
    Red Hat
    • KVM itself doesn't ship with a management interface
    • KVM itself is a bit complicated to handle
    • KVM needs Qemu to virtualize Windows guests

    • 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.

    Usability
    Red Hat
    It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

    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
    Red Hat
    • Fast provisioning of new servers.
    • Huge drop of the cost of servers compared to bare metal.
    • Easy upgrades of resources, sometimes now even requiring a server restart.

    • 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.
