Why to use Docker?
Docker can be used to pack the application and its dependencies which makes it lightweight and easy to ship the code faster with more reliability. Docker make its very simple to run the application in the production environment docker container can be platform independent if the docker engine is installed in the machine.
- Resource Efficiency: Docker helps in maximizing the resource utilization by running the multiple containers on a single host. It helps in reducing the infrastructure costs and improves the efficiency.
- Version Control: It simples the versioning for the applications and their dependencies ensuring the consistency and making easier of collaboration across the teams.
- Microservices Agility: It enables the adoption of microservices architecture, promoting the scalability, flexibility and fault isolation agile application development.
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.
