VM-based applications need to be refactored so that they can be containerized. ![]() Another way to deal with this is to use tools like KubeVirt that allow you to manage your VMs and containers through a unified platform making it easy to gradually migrate your virtual machines to containers. This isn’t ideal as you will not be able to fully benefit from containers. The container will work as a VM, but you’ll be able to run the application using a fraction of resources VM used. In that case, you can “lift and shift” the entire application to a container. However, not all applications can be broken down into services. This process is time-consuming as it may involve rewrites and some modifications to the original application. The idea is to have them as loosely coupled as possible in order to leverage containers’ full potential. Teams should take their time to chalk out how they’ll be able to break their existing applications down to independent components. Your development and operations teams should be able to work in tandem with a shared cloud-native mentality to ensure a strong foundation. Application migration is a long process and rushing it can prove detrimental to your organization’s goals.Īnother important thing to ensure before diving into migration is whether your team is prepared for the task at hand. You should avoid going all in and making too many changes all at the same time. The cloud is certainly the better option, however, if you are looking to advance slowly, you can deploy containers on-premises and migrate them to the cloud in the future. Organizations willing to take up this task should be clear on what environment they’ll be deploying their containers on (on-prem or the cloud). The most important step while beginning your migration journey is to layout the blueprint. Let’s take a look at steps you should take to ensure a smooth transition from virtual machines to containers. However, not everyone knows where to start or how to go about such a big shift. Organizations want to leverage the advantages that containerization has to offer. Shift virtual machines to containers seamlessly With containers, rolling out updates or modifications isn’t a hassle as you can roll out changes quickly without having to worry about the entire application going haywire. Essentially, containers do what VMs do, but with additional features like flexibility and scalability that make containers ideal for microservices-based applications. Containers are also portable since they don’t rely on the OS and can be migrated to and from different public cloud providers. Containers are completely isolated and don’t consume a lot of resources as they only virtualize the application and not the entire OS. Each VM needs to be configured based on the application that you will be running on it.Ĭontainers, on the other hand, are lightweight components that can share the same operating system. Having separate operating systems makes it hard to relocate or migrate applications and at the same time running separate instances of OS needs more resources. VMs are completely isolated from the host and require a separate operating system to operate. VMs are heavy virtual instances of hardware that are hosted on a single physical server. However, the difference is in the execution of the concept. VMs and containers are similar in theory as both offer an isolated environment to develop and host applications. In this article, we discuss the best practices to follow if your organization is in the process of transitioning from virtual machines to containers. And, with tools like Kubernetes, containerization became easier and more efficient. Containerization has proved to be a game-changer and has taken the IT world by storm. Enter Docker with its container technology. However, the costs to migrate outweighed the need to switch to a more flexible and scalable platform. Over the last couple of years, the cloud emerged as an incredible new way of hosting and managing previously virtualized workloads. With exponentially growing sizes of workloads, it is not just hard but also expensive to create and manage virtual machines as they consume considerable CPU and memory resources. ![]() However, as it is with everything in technology, VMs are starting to give way to newer alternatives. With modernization, the idea of breaking these servers into smaller, independent, hardware-like partitions was brought to reality by VMs. ![]() Before VMs, there were physical servers that were hard to manage. Virtual machines have been an important part of workloads in organizations for a really long time.
