The software enabling this technology comes in many forms, with Docker as the most popular. The recent rise in popularity of container technology within the data center is a direct result of its portability and ability to isolate working environments, thus limiting its impact and overall footprint to the underlying computing system. To understand the technology completely, you first need to understand the many pieces that make it all possible. Join us this weekend as we learn about Containers.
Before we get started, many ask what the difference is between a container and virtual machines? Editor Petros Koutoupis explains: Both have a specific purpose and place with very little overlap, and one doesn't obsolete the other. A container is meant to be a lightweight environment that you spin up to host one to a few isolated applications at bare-metal performance. You should opt for virtual machines when you want to host an entire operating system or ecosystem or maybe to run applications incompatible with the underlying environment.
