An analysis of container-based virtualization technologies

Container-based virtualization is a lighter virtualization idea than hypervisor technologies since it is a newer concept. It has a significantly reduced overhead and excellent isolation since it does not emulate any hardware. Instead of creating separate containers for each virtual machine, the fundamental concept is to create isolated containers that utilize the same kernel as the host system. Virtualization at the operating system level, often known as container-based virtualization, is a lightweight virtualization technique. Instead of replicating hardware, the emphasis is on creating a more efficient environment by utilizing the same kernel across all operating systems. As a result, virtualized apps or systems must share the same kernel. Such technology may help networking testbeds like Tomato since it enables multiple virtual computers to operate in parallel. Three Linux container-based virtualization solutions will be discussed in this paper. These are Open VZ, Linux-V Server, and LXC. Each technology's major characteristics and ideas will be addressed.
