Quick and rapid deployment - It takes less time to the deployment process, Even containers for every process does not require to reboot an Operating system.
Separate isolation for each resource - Docker makes separation on your application. It ensures the container has its resource that is isolated from other containers. Docker also ensures that each application uses only those resources which are assigned to it. they can not access the resources which are allocated by others.
Portability - As Docker can able o bundled all dependencies and application together, that allow to easily move between development, test and production environments.
Continuous testing and deployment - It ensures consistency in environments from development to production. Its handled all internal configuration and dependencies.
Multi-cloud platform - Almost all cloud computing providers, Amazon Web service(AWS) and Google Compute Platform(GCP) provides Docker’s support. Docker can be run inside Amazon EC2 instance, Rackspace server, Google Compute Engine instance, etc.
Security - Docker ensure that applications that are running on containers must be separated or isolated by each other. Manage whole traffic control flow.
Docker is implementation of Containerisation. This technology helps is creating applications that are highly consistent in different environments. They make code less prone to environment related issues and promotes the use of Microservies architecture.
