CloudWatch
CloudWatch is Amazon's tool for keeping an eye on cloud-based systems and applications. Think of it like a dashboard that shows how well computer systems are running in the cloud. It helps technology teams track important measurements, spot problems before they become serious, and automatically respond to changes. It's similar to other monitoring tools like Datadog or New Relic. When you see this on a resume, it usually means the person has experience making sure cloud systems run smoothly and efficiently. You might also see it referred to as "AWS CloudWatch" or "Amazon CloudWatch."
