AWS Lambda cold starts were killing our API. Provisioned concurrency fixed it! Went from 2-3 second cold starts to consistent 200ms responses. The cost increase was minimal compared to user experience improvement. Also optimized our function packages - smaller bundles = faster starts. #serverless #lambda #aws #performance

Implemented blue-green deployment. Zero-downtime releases are now our standard! AWS CodeDeploy handles the traffic shifting automatically. Rollbacks happen in seconds if health checks fail. The team deploys with confidence now - even on Fridays. Well, maybe not Fridays. #deployment #devops #cloud #zerodowntime

Monitoring stack complete: Prometheus + Grafana + AlertManager. No more surprises in production! Created custom dashboards for each service. Alert fatigue was real at first - tuned thresholds over 2 weeks. Now we get meaningful alerts that actually require action. On-call life improved dramatically! #monitoring #prometheus #grafana #observability

Just migrated our entire infrastructure to AWS. The cost savings with reserved instances are incredible! Went from $15k/month to $8k/month by right-sizing instances and using Savings Plans. The migration took 3 months but the ROI was achieved in just 6 months. Planning and tagging were crucial! #aws #cloud #infrastructure #costoptimization
