Is Docker Perfect for Databases?
Docker – a Revolutionary Container Platform
Before going into the analysis, let’s have a brief idea about Containers and Docker. A Container is an executable package of software designed to provide an isolated environment for applications to run in a host server. They have all the necessary code, runtime, libraries etc. to provide a safe environment for the application software. Prominent enterprises like Uber, Facebook, Google etc are using Containers in a very high scale. Docker is a software container platform and is used to create container units on host machines. Many such units share the host’s OS, RAM, Processor and other resources. Disk usage is minimized by sharing filesystem layers and common files. Docker containers help in many aspects for Software Lifecycle, starting from development to deployment and implementation. It provides an agile continuous integration platform with isolated units for development teams, with development, test and production environments. It makes a server compatible for a wide variety of software applications that have different dependencies. Docker makes the host platform portable and distributed by virtue of its self sufficient and isolated container feature. All these come along with reduced need of computing power and space, since Docker Containers use the same Kernel in a host, rather than VMs using separate guest OS.
