If you want to build a career that involves automation, cloud, CI/CD, monitoring, deployment, and handling real-time infrastructure, then DevOps is one of the best and most in-demand career paths in IT today. Almost every modern company follows DevOps culture to speed up development and improve application reliability. This increases the need for skilled DevOps engineers every year.
🔹 What is DevOps?
DevOps = Development + Operations
It is a culture, practice, and set of tools that brings the development team and operations team together. The goal is to deliver software faster, more reliably, and with fewer failures through automation and continuous integration/deployment pipelines.
Main purpose of DevOps:
- Automate build, testing, and deployment
- Reduce development time and release faster
- Improve application performance and reliability
- Create scalable and secure infrastructure
- Monitor production applications
- Reduce manual work using automation
