Fundamentals of Devops

1. Collaboration & Communication:

 In traditional models, developers (Dev) and operations (Ops) teams work in silos, often causing delays and miscommunication. DevOps encourages constant collaboration between both teams, ensuring smoother workflows and faster delivery.

2. Automation

 DevOps focuses on automating repetitive tasks, like testing, deployment, and configuration management. This ensures faster and more consistent results while reducing human errors.

3. Continuous Integration (CI)

 Continuous Integration involves regularly merging code changes from multiple developers into a central repository. Automated tests run to check for issues, ensuring that the code is always in a deployable state. This practice helps detect problems early, making it easier to fix bugs.

4. Continuous Delivery (CD)

 Continuous Delivery is about automating the release process, so that software can be delivered to production with minimal manual intervention. This ensures that new features and bug fixes are rolled out quickly and reliably.

5. Monitoring and Feedback:

 Continuous monitoring of the application and its environment is essential to detect issues, track performance, and gather feedback. This feedback loop allows teams to make improvements and prevent future issues.

6. Infrastructure as Code (IaC):

 Infrastructure as Code means managing and provisioning IT infrastructure (like servers, networks, etc.) through code and automation. This makes it easier to scale and manage environments, while also reducing errors due to manual configurations.

7. Version Control:

 Using version control systems (like Git) allows teams to track changes, collaborate on code, and roll back to previous versions when necessary. This is fundamental in a DevOps environment to keep code organized and safe.

8. Microservices:

 Instead of building large, monolithic applications, DevOps encourages breaking down applications into smaller, independent services (called microservices). Each service can be developed, tested, and deployed independently, making it easier to scale and maintain.

9. Cloud Computing:

 DevOps teams often leverage cloud platforms (such as AWS, Azure, or Google Cloud) for hosting and scaling applications. Cloud platforms provide the flexibility and resources needed for continuous integration and delivery.

10. Security (DevSecOps):

 In DevOps, security is integrated early in the development process, rather than as an afterthought. This approach is called DevSecOps, which ensures that security practices and checks are automated throughout the CI/CD pipeline.
