VMs: What’s the difference?“Įngineers can use containers to quickly develop applications that run consistently across a large number of distributed systems and cross-platform environments.

The absence of a guest host significantly reduces the size of a container, making it lightweight, fast and portable.įor a full rundown on the differences between containers and VMs, see “ Containers vs. A container, on the other hand, includes only an application and its libraries and dependencies. With traditional virtualization, each VM contains a full copy of a guest operating system (OS), a virtual copy of the hardware needed to run the OS, as well as an application and its associated libraries and dependencies.
Both are based on virtualization technologies, but while a container virtualizes an OS, a VM leverages a hypervisor - a lightweight software layer between the VM and a computer’s hardware - to virtualize physical hardware. One way to understand the concept of a container is to compare it to a virtual machine (VM).
#Is docker and kubernetes the same portable#
A container stands alone it is abstracted away from the host operating system (OS) - usually Linux - which makes it portable across IT environments. What is a container?Ī container is an executable unit of software that packages application code with its dependencies, enabling it to run on any IT infrastructure. To do so, it’s important to start with the foundational technology that ties them together: containers. In this post, we’ll explore the fundamentals of Kubernetes and Docker and take a look at the advantages of using them individually and in tandem. And while they excel in their respective areas, they also are complementary and can be powerful when combined. They are, in fact, fundamentally different technologies and don’t compete - it’s not an either/or question. A lot of people want to know which option is better, but that question is based upon a misconception. When it comes to container technologies, two names emerge as open source leaders: Kubernetes and Docker. This post looks at how the two powerful technologies can complement each other. Although many people want to compare Kubernetes and Docker, it's not actually an either/or question.
