In this series, we will learn one of the most important skills in the post-2025 tech era — DevOps Because nowadays, cloud computing is used everywhere, and DevOps is the bridge that helps teams build, deploy, and scale applications efficiently on the cloud.
This is the first tutorial, where we’ll cover the fundamentals:
What is DevOps?
Why does DevOps matter?
Whether you are a frontend developer, backend engineer, complete beginner, or someone transitioning into DevOps, this series is designed for you.
Even if you work in AI, Cybersecurity, Cloud, or Software Engineering, understanding DevOps is no longer optional — it’s a core skill for building, deploying, and scaling real-world systems.
We’ll start from the basics and gradually move toward production-grade practices, helping you build a strong DevOps mindset along the way.
Let’s get started.
What is DevOps?
DevOps is a set of practices, processes, and a culture that improves software delivery by ensuring:
a) Automation – reducing manual work across build, test, and deployment
b) Quality – delivering reliable and stable software
c) Continuous Testing – detecting issues early and frequently
d) Continuous Monitoring – observing system health and performance in real time
In simple terms, DevOps help s teams build, test, deploy, and operate software faster and more reliably.
Why there is DevOps?
10 years before when DevOps system was not the there the system looks like this :
Developer first write the code.
Then “System administrator” upload the code to a server everyone can check the code and use that for tests.
Then “tester” , install all the code along with the system configuration to run and test the code.
Then it go for pre-production after that it’s ready to go to production/ client.
All total it will take 10-12 days just to go from Development to Production/Client.
DevOps Era:
Developer first write the code.
Then it’s go to DevOps team.
Then it go for pre-production after that it’s ready to go to production/ client.
Unlike pre-Devops era, In DevOps era All total it will take 3-4 days just to go from Development to Production/Client.
Ending note :
DevOps isn’t about becoming an expert overnight — it’s about owning the system end to end.
If you can write code and understand how it runs, fails, and scales, you’re already on the DevOps path.
