Linux containers are hugely complicated and not user-friendly. Having realized the fact that several complexities are coming in the way of massively producing and fluently using containers, an open-source project got initiated with the goal of deriving a sophisticated and modular platform comprising an enabling engine for simplifying and streamlining the life cycle phases of various containers. This means that the Docker platform is built to automate the crafting, packaging, shipping, deployment, and delivery of any software application embedded inside a lightweight, extensible, and self-sufficient container. Docker is positioned as the most flexible and futuristic containerization technology in realizing highly competent and enterprise-class distributed applications. This will make deft and decisive impacts on the IT industry, as instead of large monolithic applications distributed on a single physical or virtual server, companies are building smaller, self-defined and sustainable, easily manageable, and discrete ones. In short, services are becoming microservices these days in order to give the fillip to the containerization movement.

The Docker platform enables artistically assembling applications from disparate and distributed components and eliminates any kind of deficiencies and deviations that could come when shipping the code. Docker, through a host of scripts and tools, simplifies the isolation of software applications and makes them self-sustainable by running them in transient containers. Docker brings the required separation for each of the applications from one another as well as from the underlying host. We have been hugely accustomed to VMs that are formed through an additional layer of indirection in order to bring the necessary isolation. This additional layer and overhead consumes a lot of precious resources and is hence an unwanted cause of the slowdown of the system. On the other hand, Docker containers share all the resources (compute, storage, and networking) to the optimal level and hence can run much faster. Docker images, being derived in a standard form, can be widely shared and stocked easily for producing bigger and better application containers. In short, the Docker platform lays a stimulating and scintillating foundation for optimal consumption, management, and maneuverability of various IT infrastructures.

The Docker platform is an open-source containerization solution that smartly and swiftly automates the bundling of any software applications and services into containers and accelerates the deployment of containerized applications in any IT environments (local or remote systems, virtualized or bare metal machines, generalized or embedded devices, and so on). The container life cycle management tasks are fully taken care of by the Docker platform. The whole process starts with the formation of a standardized and optimized image for the identified software and its dependencies. Now the Docker platform takes the readied image to form the containerized software. There are image repositories made available publicly as well as in private locations. Developers and operations teams can leverage them to speed up software deployment in an automated manner.

The Docker ecosystem is rapidly growing with a number of third-party product and tool developers in order to make Docker an enterprise-scale containerization platform. It helps to skip the setup and maintenance of development environments and language-specific tooling. Instead, it focuses on creating and adding new features, fixing issues, and shipping software. "Build once and run everywhere," is the endemic mantra of the Docker-enabled containerization. Concisely speaking, the Docker platform brings in the following competencies:

• Agility: Developers have the freedom to define environments and the ability to create applications. IT operation teams can deploy applications faster, allowing the business to outpace the competition.
• Controllability: Developers own all the code from infrastructure to application.
• Manageability: IT operation team members have the manageability to standardize, secure, and scale the operating environment while reducing overall costs to the organization.
