  • Virtual machines boot is slow.
  • Moving the software workloads to the cloud is hard in VM technology.
  • Managing Software licenses is expensive
  • Security maintenance is laborious, as you need to take care of all the VMs.

  • Containers take less CPU and RAM because the operating system is one.
  • Software licensing support for Os is minimal.
  • Portability wise these are ultra-fast.
  • Creating a container with the software workload is easier.
  • Moving software workloads to the cloud is smoother.
