CloudFront CDN reduced our bandwidth costs by 40%. Cache invalidation is the only hard part! Set up origin shield to reduce load on our servers. Custom cache policies per content type. The edge locations make a huge difference for global users. Just remember: there are only two hard things in CS... #cdn #cloudfront #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

VPC peering between our staging and production accounts. Network isolation done right! Each environment has its own AWS account. Transit Gateway connects them when needed. Security groups are locked down to specific CIDR blocks. The network diagram finally makes sense to auditors! #aws #vpc #security #networking

Terraform tip: Always use modules for reusable infrastructure. Our deployment time dropped by 60%! Created modules for common patterns - VPC, EKS cluster, RDS. New environments can be spun up in 15 minutes instead of days. State management with S3 backend and DynamoDB locking is rock solid. #terraform #iac #devops #automation

Container security scan found 3 critical vulnerabilities. Always scan before deploying! Integrated Trivy into our CI pipeline. Base image updates are now automated with Dependabot. Created a policy that blocks deployments with HIGH or CRITICAL findings. Security is everyone's responsibility! #security #docker #devops #containersecurity

Ansible playbooks for configuration management. Consistent servers across all environments! Idempotent tasks mean running playbooks multiple times is safe. Vault handles secrets encryption. Integrated with our CI/CD for automatic configuration drift detection. Infrastructure as code all the way down! #ansible #automation #devops #configmanagement

Docker Compose for local development, Kubernetes for production. Best of both worlds! The key was making the configs as similar as possible. Environment variables bridge the gap. Developers can run the full stack locally with one command. Onboarding new team members is now a breeze! #docker #kubernetes #devops #development

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
