Site Reliability Engineering - approach that applies software engineering principles to infrastructure and operations. Like having software developers who specialize in making systems reliable and scalable.
SRE teams write code to automate operations tasks, design systems for reliability, and set error budgets to balance innovation with stability.
SRE (Site Reliability Engineering) is an operating model and set of practices, not a single cloud service. All major cloud providers offer building blocks SRE teams commonly use (monitoring, logging, incident management, CI/CD, IaC), but there is no direct one-to-one managed service called “SRE” on AWS, Azure, Google Cloud, or OCI.
