The following article describes Docker and Traditional Virtualization. Docker is an open-source platform that allows developers to build, package, and deploy applications as lightweight, portable containers. It uses operating-system-level virtualization to run multiple containers on a single host, with each container sharing the host’s kernel. In traditional virtualization, a hypervisor is used to create virtual machines that emulate a complete […]
