6 Top Container Vs. VM Quick Differences

In the cloud computing age, Containers play prime role. Containers concept supports by Docker, and VMware supports Virtual machines. Performance-wise these two not the same, then this post is for you to know the differences between these two.

6 Top Container Vs. VM Quick Differences

Virtual Machine.

  1. Virtual machines form on top of the host operating system. So each VM plays in separate Os, which means the operating systems are not sharable.
  2. When you add more VMs, each will consume CPU and RAM resources.
  3. Virtual machines boot is slow.
  4. Moving the software workloads to the cloud is a bit hard in VM technology.
  5. Software licenses support, in the case of VMs, is heavy.
  6. Security maintenance is laborious, as you need to take care of all the VMs.

Container Benefits Over VM.

  1. One Os is enough for containers – can have many of these in one Os.
  2. Containers take less CPU and RAM because the operating system is one.
  3. Software licensing support for Os is minimal.
  4. Portability wise these are ultra-fast.
  5. Creating a container with the software workload is easier.
  6. Moving software workloads to the cloud is smoother.
