Why Docker is popular?
Docker gained its popularity due to its impact on the software development and deployment. The following are the some of the main reasons for docker becoming popular:
- Portability: Docker facilitates the developers in packaging their applications with all dependencies into a single lightweight containers. It facilities in ensuring the consistent performance across the different computing environments.
- Reproducibility: Through encapsulating the applications with their dependencies within a container it ensures in software setups remaining consistent across the development, testing and production environments.
- Efficiency: Docker through its container based architecture it optimizes the resource utilization. It allows the developers to run the multiple isolated applications on a single host system.
- Scalability: Docker’s scalability features facilitated the developers in making easier of their applications handling at time of workloads increment.
What is Docker?
Docker is a set of Platforms as a service (PaaS) products that use Operating system-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and therefore use fewer resources than a virtual machine.
