- Containers are the next evolution of virtualization. Containers are a lightweight way to package up an entire application and make it portable, so that it can easily move between hardware platforms. In traditional virtualization, we have hardware that supports a hypervisor and then that hypervisor supports guest virtual machines. Each one of those guest machines runs its own operating system and applications, allowing the applications to function somewhat independently of the hardware. You can move a virtual machine from hardware to hardware, as long as the machines are running the same hypervisor. And one of the downsides to traditional virtualization is that virtual machines are somewhat heavy. Each one has to have its own operating system and components. If you're running 10 different windows virtual servers on a hypervisor, you have the overhead of running 10 different copies of windows at the same time.…
