What is Docker?
Docker is an open platform which provides the ability to run an application in a loosely isolated environment called container.
Docker enables you to separate your applications from your infrastructure which enables us to manage our infrastructure in the same ways you manage your applications.
Why even Use Docker?
# Fast and Consistent delivery of your applications
Containers can be created locally and pushed to testing environment and execute automated and manual tests after if testing is successful, it is automated to production.
Just like that...So Containers are the best for continuous integration and continuous delivery (CI/CD) workflows.
# Responsive Deployment and Scaling
Docker's Portability and lightweight nature makes it easy to dynamically manage workloads.
Docker containers can be run on your local laptop, your virtual machine in a data center, cloud providers and even in hybrid environments.
# Running More Workloads on the same Hardware
Fast and Lightweight nature also provide a viable, cost-effective alternative to hypervisor-based virtual machines. Docker is your choice when you have few resources and in need of perfection.
