Why Docker Popular ?

Why Docker Popular-

1. Portability: Docker ensures that applications run consistently across any environment, from a developer's personal laptop to the production server, avoiding the common pitfall of encountering bugs and inconsistencies due to environment-specific differences.
2. Efficiency: Containers share the host system's kernel and do not require an operating system per application, making them lighter and faster than traditional virtual machines. This efficient use of system resources translates to faster start-up times and more scalable solutions.
3. Isolation: Docker provides application isolation, which improves security and allows multiple containers to run simultaneously on the same host without interference. Each container has its own filesystem, ensuring processes are separated and resource usage is controlled.
4. Version Control and Component Reuse: Docker images can be versioned, shared, and reused. This is akin to version controlling the entire environment. Developers can push their Docker images to a registry (such as Docker Hub) and pull them down for use without needing to set up environments manually.
5. CI/CD : Docker simplifies the development process by allowing developers to create local environments that match production systems. Additionally, Docker works well with continuous integration and deployment (CI/CD) systems Automating the deployment process and ensuring that applications are deployed consistently.
