Docker is a platform thats open source and enables developers to build and manage cloud applications efficiently with tools tailored for personal use as well, as education and business settings.
Using Docker on your computer offers an efficient method to deploy applications consistently and quickly across different platforms This makes it a favored choice for testing new ideas rapidly and deploying projects reliably for clients, around the world.
This tool was created from scratch as a platform, for users of any expertise level to utilize a top tier collection of operating system level virtualization software enabling them to create highly adaptable web applications using individual containers.
The web applications that are created can be conveniently used on any up to date Windows PC or Mac computer well as Linux systems and can be scaled to work in house or, through public and private cloud services.
Originally introduced to the public as an available project in 2013 this Platform as a Service (PaaS) solution underwent significant development over the following ten years offering an efficient web application platform tailored for individuals, groups and enterprises of varying scales through five unique subscriptions – Docker Personal, Pro, Team, Business and Scout.
The platform comes in premium options with easy access to various functions such as automated division of tasks and enhanced security measures including the ability to run multiple containers on a single virtual machine server, for improved scalability.
