DevOps is a set of practices, principles, and cultural philosophies that integrates software development and IT operations to improve collaboration, automate processes, and enable the continuous delivery of high-quality software with greater speed, reliability, and scalability.
DevOps majorly consists of following areas-
- ⏳ Version Control System
- 🐳 Containers
- ☸️ Container Orchestration tools
- 🛠️ Infrastructure as Code
- ⚙️ Continuous Integration and Continuous Delivery
- 🚀 GitOps
Git is a distributed version control system used to track changes in source code during software development, enabling multiple developers to collaborate efficiently, manage code history, and maintain different versions of a project.

Docker lets you run applications in isolated environments, independent of the operating system. So that we don't need to test our application in all kinds of operating systems and runtimes.

Infrastructure as Code (IaC) is the practice of defining and managing infrastructure using code instead of manual processes. Servers, networks, databases, and cloud resources are described in machine-readable configuration files and provisioned automatically.
Terrform is one of the most poplular IaC tool.
