Part 2: Understanding the Stages of DevOps

As I wrap up Day 1 of my learning journey, I explored the various stages involved in DevOps, their purposes, and tools commonly used at each stage. Here's what I learned!

Stages of DevOps

1. Version Control

   • Purpose: Maintains different versions of the code. It is essential when multiple developers are working on the same codebase, as it systematically stores changes, making it easier to correct errors.

   • Example Tool: Git

---

2. Continuous Integration (CI)

   • Purpose: Automates the process of compiling, validating, code reviews, unit testing, and integration testing for each update in the code.

   • Example Tool: Jenkins

---

3. Continuous Delivery (CD)

   • Purpose: Automates the deployment of the built application to test servers, ensuring it is ready for further validation.

   • Example Tool: Selenium

---

4. Continuous Deployment

   • Purpose: Automatically deploys the tested application to the production server for release.

   • Example Tool: Docker

---

5. Continuous Monitoring

   • Purpose: Monitors the application and infrastructure in production to identify and resolve issues quickly.

   • Example Tool: Splunk

---

Key Takeaway

DevOps is a continuous process that integrates development and operations seamlessly. Each stage has a specific role, and tools like Git, Jenkins, Docker, and Splunk play a crucial role in automating and streamlining the workflow.

What’s Next?

That’s it for the basics of DevOps! From tomorrow, I’ll begin my journey into "Linux for DevOps" to build a strong foundation for managing systems effectively.
