Solution: Diagnosed auto-scaling misconfiguration, restored instances in 12 minutes, implemented failover architecture.

Result: 100% uptime recovery, prevented $600K potential loss

Problem: Monthly AWS bill jumped from $8K to $47K due to unmonitored data transfer and idle resources.

Solution: Identified NAT gateway overuse, terminated zombie instances, implemented cost alerts and reserved instances.

Result: Reduced monthly costs to $9.5K, saved $450K annually

Problem: Critical patient records inaccessible due to S3 bucket policy error, violating HIPAA compliance.

Solution: Emergency IAM policy correction, implemented role-based access control, enabled CloudTrail auditing.

Result: Access restored in 8 minutes, HIPAA compliance maintained

Problem: 200+ on-premise servers needed migration to AWS with zero downtime requirement and data loss risk.

Solution: Phased migration strategy using AWS Migration Hub, database replication, comprehensive testing protocols.

Result: 100% successful migration, zero data loss, 3 weeks early

Problem: Production database experiencing constant timeout errors, affecting 2M+ users during live streaming.
