Overview
Docker is one of the popular and container-based tools used to create, deploy and run applications on cloud and on premises. Docker is a key component for the strategic investment in any company. An organization can take advantage of the agility and portability benefits that Docker containers provide across the application lifecycle, organizations planning to optimize these applications for their digital and hybrid cloud initiatives require a broader containerization strategy.
Docker is one type of open-source solution for the management of isolated containers. Docker always helps to put software code in containers. For this reason, it can be used in other systems without the necessity to create resource-intensive virtual machines. The software can be managed either via a hybrid Cloud or with the help of existing physical hardware resources. Docker Containers are virtualized abstract objects that interconnect code into dependencies (e.g., frameworks, config files, libraries, etc.). They are used for the building and deployment of lightweight applications that can be installed in a package on one machine (server or powerful computer). The containers finally boost performance and save memory, consuming far less resources than traditional virtual machines (also called hypervisors).
