Hardware virtualization provides a list of advantages such as scalability, security, isolation, etc. by using hypervisors for sharing physical hardware with virtual machines (VMs). At present, virtual machines are not the only form of virtualization, as containers have also become quite popular. While VMs share physical hardware of underlying machines, containers share the kernel of the underlying operating system. Containers are not lightweight virtual machines, but are standardized executable packages used to deliver applications, including applications that are developed by using the microservice-based software architecture, and include all components necessary to run applications.
