Docker allows developers to package applications and dependencies into standardized units called containers that can run on any Linux host. Containers are created from Docker images, which are blueprints that define what is in the container. The Docker daemon manages building, running, and distributing containers, while the Docker client allows users to interact with the daemon. Docker Hub is a registry for Docker images, and containers provide benefits like standardization, portability across clouds, and easier management of microservice architectures.

1. Docker Containerized Approach

2. What is Docker?
● Help to package an application with all its
dependencies into standardized unit
● Easily deploy application on host operating system
i.e. Linux
● Plug and play like feel
● Great usability for dev-ops and developers

3. How do they do it?
● Docker image - blueprint for application.
● Docker container - create running instance of
application from docker image.
● Docker daemon - background services that manages
building, running and distributing containers.
● Docker client - allows user to interact with daemon
● Docker Hub - registry for docker images

4. How do they do it?

5. Why should I use it?
● Standard APIs
● Open Source and Great community
● Almost every cloud provider has docker as service
● Changed faced of technology landscape
● Easy to handle microservice architecture
● Be with trend and see how we get benefits

6. Why should I use it?
● Just in number, in mid 2014, Google claimed it runs
around 2 billions containers per week
