Decoding Docker Cloud - the state-of-the-art open-source software container
Docker is an open-source software container system. A container system helps a software to run glitch-free when it is moved from one environment (like from design to production). The container will have all the necessary facilities like tools, operating system, code, host, libraries, etc. that the software will need to function without experiencing issues.
Unlike in traditional virtual machine (VM), where the entire ecosystem for running the software is created completely, Docker PaaS allows applications to run on the same LInux Kernel. Only such infrastructure that the kernel does not have is shipped along with the software. This helps reduce a large chunk of unnecessary space of the applications thus boosting its agility significantly.
Who uses Docker containers?
Docker containers are meant primarily for:
1. Developers
2. Administrators
Its dual benefit ensures a steady presence in most Devops operations. Docker cloud empowers developers to focus on the programming alone without having to be distracted or worry about the end system where it will ultimately run on. Moreover, they also get access to a wide variety of applications that are ready to fit in and function in the Docker container platform.
This also translates into a major benefit for operations staff and system administrators. The ready availability of applications reduces the need to develop or manage additional applications. It simplifies their task while delivering equal performance as in a native VM environment.
When to use Docker containers?
Docker is ideal for use in the following scenarios:
• When configuration needs to be simplified for application running
• When the differences arising in code pipeline movement is to be reduced
• When developer productivity is to maximized at zero dollar cost
• When all existing server systems need to brought under one roof
There is much use case scenarios to Docker containers. From debugging to multi-tenancy Docker can help run diverse applications run smoother and easier without being bogged down by system indifferences.
