Down to the exact invocation • Use custom labels for intelligent logging, filtering and advance searching • Setup auto-triaged alerts based on custom triggers End-to-end App Automation • Leverage deployment templates & frameworks with built-in best practices to create functions, APIs, databases, and event source mappings • Automate backups and disaster recovery mechanisms through intelligent routing • CI/CD toolchain integration A large event driven serverless application may have 100s of services firing off millions of events per minute. NoOps is critical in ensuring application sustainability during test, deploy, log and monitor Automate Security • Setup rules engine for cloud security, cost optimization, and governance • Automate security guardrails ensuring real time enforcement of security policies (e.g. encryption, access requirements) Local Debugging And Testing • Develop and test locally in prod-like environment • Tighten development loop by finding issues locally before deploying to the cloud.
