In layman terms, Docker means a person employed in a port to load and unload ships.
Technically, it is a software platform that builds, test, and deploy applications quickly.
It is a set of platform-as-a-service (PaaS) products that use OS-level virtualization to deliver software in packages called containers.
Docker packages an application and dependencies in a virtual container and ships it out as one package.
This enables flexibility and portability; enabling to run the application on on-premises, public cloud, or private cloud.
No need to set-up and configure the environment each time to test or deploy code; Docker automates development to deploying process.
It consists of:
- Docker Enterprise: Premium and ideal for enterprises
- Docker Community: Open source and ideal for individuals and small teams
With Docker, it is easy to
- build and run distributed microservices architectures
- deploy code with continuous integration & delivery pipelines
- build highly-scalable data processing system
- create a fully-managed platform
Enterprises like JP Morgan Chase, Inc., etc. implement Docker to scale their application.
32000+ Github Stars & 80B Container Downloads shows its acceptance worldwide.
Docker helps to build modern applications and can surely help to stay competitive in the ever-changing world
