Problem: Manual ECS deployments caused downtime and rollback risks.
Solution: Automated CI/CD pipeline using CodePipeline, CodeBuild, ECR, and ECS Blue-Green strategy to deploy new versions safely.
Outcome: Achieved 0% downtime deployments and reliable, automated production rollouts.
Problem: Instances ran 24/7 increasing cost.
Solution: Lambda + EventBridge schedules to start/stop tagged EC2.
Outcome: ~40% cost savings off-hours.
Problem: No unified monitoring/alerts.
Solution: Grafana, Prometheus, Loki, Promtail, Blackbox, Node Exporter.
Outcome: Faster detection, lower MTTR.
Problem: Manual web deployments.
Solution: S3 hosting + CloudFormation infra + CI/CD pipeline.
Outcome: Reliable, one‑click releases.
Problem: Required secure migration of apps and DBs.
Solution: Hardened firewalls (Sophos/SonicWall), web servers, and databases with staged cutovers.
Outcome: Zero security incidents post‑migration.
Problem: Need secure hybrid connectivity.
Solution: Public/private subnets, VPN (OpenVPN), ALB, RDS MySQL/MongoDB.
Outcome: Scalable, secure architecture.
