Need Insights for Devops

Insights would be incredibly helpful.

To give you some background, I have 6 years of experience, having worked at IBM and currently at TCS. My work has primarily involved Azure, Terraform, and Azure DevOps, but mostly in support roles, so I haven't had the opportunity to gain in-depth, hands-on experience.

Now, I’m looking to seriously build my knowledge and skills in DevOps. Based on your experience, could you please advise me on where to start and which tools or technologies I should focus on? For example, what should I learn for CI/CD, scripting languages, etc.?

Your guidance would mean a lot to me. Thank you in advance!
