9. More often than not we hear shift left in DevOps. What is it?

Shift Left is a practice intended to find and prevent defects early in the software delivery process. The idea is to improve quality by moving tasks to the left as early in the lifecycle as possible. Shift Left testing means testing earlier in the software development process.

10. What does CAMS in DevOps stand for?

CALMS is a framework that assesses a company's ability to adopt the DevOps processes, as well as a way of measuring success during a DevOps transformation. The acronym was coined by Jez Humble, co-author of “The DevOps Handbook,” and stands for Culture, Automation, Lean, Measurement, and Sharing.
