Understand the basics of VMware container technology

VMware vSphere has long been the dominant platform for server virtualization. However, in recent years, container technology has rapidly gained ground in the company, prompting the company to develop its own VMware container management tools.

Containers are a bit like virtual machines, but with some important differences. First, containers do not contain a full stack, but rather use a basic system that shares multiple containers. Secondly, containers are usually non-permanent, although there are ways to keep the container's data. Third, container technology originated in the Linux world and in the past required an infrastructure and set of management tools that were completely separate from the organization's server virtualization platform.

VMware added container support to vSphere with a feature called vSphere Integrated Containers (VIC) to address this growing interest. VIC seamlessly integrates containers into the vSphere infrastructure, which simplifies container deployment and management for VMware administrators.

Most importantly, all VIC components are open source and VMware does not require additional licenses that go beyond what vSphere normally requires.
