Compartmentalization that comprises both virtualization and containerization is the new normal for IT agility. Virtualization has been the enigmatic foundation for the enormous success of cloud computing. Now with the containerization idea becoming ubiquitous and usable, there is a renewed focus on using containers for faster application building, deployment, and delivery. Containers are distinctively fitted with a few game-changing capabilities and hence there is a rush in embracing and evolving the containerization technologies and tools.

Essentially a container is lightweight, virtualized, portable, and the software-defined environment in which software can run in isolation of other software running on the same physical host. The software that runs inside a container is typically a single-purpose application. Containers bring forth the much-coveted modularity, portability, and simplicity for IT environments. Developers love containers because they speed up the software engineering whereas operation team loves because they can just focus on runtime tasks such as logging, monitoring, lifecycle management and resource utilization rather than deployment and dependency management.
