Docker Overview Overview Docker is the organization driving the container movement and the sole container platform provider to address every application over the hybrid cloud. Today's businesses are under great pressure to digitally transform but are controlled by existing applications and infrastructure though rationalizing an ever more diverse portfolio of clouds, datacenters and application architectures. Docker enables right freedom among applications and infrastructure and developers and IT ops to unlock their prospective and creates a product for better collaboration and innovation.
A little intro to LXC: LXC (LinuX Containers) is a OS-level virtualization technology that allows creation and running of multiple isolated Linux virtual environments (VE) about the same control host. These isolation levels or containers can be used to either sandbox specific applications, or even to emulate a completely new host. LXC uses Linux's cgroups functionality, that has been introduced in version 2.6.24 to allow the host CPU to higher partition memory portion into remoteness levels called namespaces. Note that a VE is distinct from an electronic machine (VM), as we will see below. Docker, previously called dotCloud, was started as a part project and only open-sourced in 2013. It is really an extension of LXC's capabilities. This it achieves employing a high-level API that gives a light virtualization solution to perform processes in isolation. Since it's based on LXC, a Docker container does not consist of a separate operating-system, instead it utilizes the operating systems own functionality as supplied by the underlying infrastructure. So Docker acts as a portable container engine, packaging the application and all its dependencies in an electronic container that will operate on any Linux server.
