CloudGuard
Production-Grade Resilient AWS InfrastructureA self-healing, multi-AZ AWS infrastructure built from a custom VPC — Auto Scaling, CloudWatch-driven alerting, and a fully version-controlled provisioning pipeline, designed for high availability with zero single points of failure.
- Architected a multi-AZ Auto Scaling Group inside a custom VPC using Launch Templates & Golden AMIs, eliminating single points of failure across the EC2 fleet.
- Designed CloudWatch alarm-driven scaling policies (CPU-based scale-in/out) wired to SNS notifications for real-time infrastructure health alerting.
- Enforced least-privilege access using scoped IAM roles and policies, keeping provisioning and scaling actions tightly permissioned.
- Authored a 10+ step IaC-style provisioning pipeline, version-controlled via Git — simulating production-grade operational runbooks and repeatable delivery.
- Built for high availability: Auto Scaling Group spans multiple Availability Zones so instance or AZ failure doesn't take down the service.
- Established proactive incident visibility — CloudWatch alarms fire before capacity issues become outages, not after.
