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

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

Implemented GitOps with ArgoCD. Infrastructure changes are now version-controlled and auditable! Every change goes through PR review. Rollbacks are just git reverts. The sync status dashboard gives us confidence that production matches our repo. Compliance team loves the audit trail! #gitops #argocd #kubernetes #devops

Load balancer configuration matters! Switched to least connections algorithm and improved response times. Was using round-robin but some backend instances were getting overwhelmed. Added health checks with proper thresholds. Also implemented connection draining for graceful deployments. #nginx #loadbalancing #cloud #performance

Azure DevOps pipelines are surprisingly powerful. Parallel jobs cut our build time in half! Set up a matrix strategy for testing across environments. Artifact caching reduced redundant work. The integration with Azure resources is seamless. Template reuse across projects saves so much time! #azure #cicd #devops #automation

Disaster recovery drill successful! RTO of 15 minutes achieved with our backup strategy. Tested full region failover on AWS. Route53 health checks trigger automatic DNS failover. Cross-region RDS replicas were the key. Documented everything and trained the team. Sleep better knowing we're prepared! #disasterrecovery #cloud #backup #businesscontinuity

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
