VM a.k.a Virtual Machine, I guess everybody knows already what it is. But Container? Probably you just heard about it recently and that’s likely what brings you here – what are the main differences between a Container and a VM. Aren’t they the same?
They are the same – in terms of virtualization. Both technology – Container and VM – enables virtualization. However, fundamentally they are different.
Differences between a Container and a Virtual Machine
VM is virtualization at machine level – that’s why they got the name as virtual machine. They have separate or should I say – dedicated – predefined resources: CPU, Memory and Hard disk space.
While Container is aiming to be more efficient than a VM. Container is virtualization at operating system level.
Or in more friendly language:
Think a Virtual Machine (VM) is a computer or a laptop but virtual and it sits inside a container everybody knows as a VM.
While Container is – put it in simpler terms – think of it like an application/program, but virtual – it sits inside a container what today people called as Container (and the process is called containerization). To note, it’s not necessarily just one program or one process. Inside a Container, it could be sets of programs or processes.
Here’s some other differences.
|Virtualization||Machine level |
(contains CPU, RAM, HDD)
|Operating system level|
since it’s a whole computer
since only a handful of
processes / programs
|OS-wise||A separate full OS from host||Share kernel with host|
|Great for||Providing functionality|
just like a normal
|Cloud ready application,|
process, apps or programs
|Known names||VMWare, VirtualBox||Docker, Kubernetes|
Well, in case you still don’t get the differences between the two, I don’t blame you. But here’s a YouTube video which probably can help you to better understand what is a Container and how is it different from Virtual Machine.
Hopefully, after reading and seeing the video above, now you know the fundamental differences between a Container and a Virtual Machine.
Is Container always better than VM?
Since Container is smaller in size, cloud-ready and doesn’t need a lot of resources (sharing directly with host), so is Container always the choice to go?
Well, depends on your use case. Containers are known and best for non-interactive, headless and stateless apps. So if the programs, processes or applications are not meeting those criteria, they may not be a good candidate to be containerized.
