AWS Elastic Disaster Recovery (DRS), Amazon EC2, Amazon EBS, Amazon RDS, Amazon ALB, Amazon VPC, AWS IAM, Amazon CloudWatch
Built a cross-region DR architecture with rapid recovery, non-disruptive drills, and ransomware resilience.
The client is a fast-growing EdTech company focused on delivering scalable and interactive digital learning platforms across India. The organization relies heavily on cloud infrastructure to support live sessions, content delivery, and student data management, making high availability and disaster resilience critical to its operations.
RTO Reduced
RPO Achieved
Improved business continuity
The organization lacked a cross-region disaster recovery mechanism, defined RTO/RPO objectives, and a database failover strategy, creating significant downtime risk for live classes and assessments. Manual recovery processes, inability to conduct non-disruptive DR drills, and limited visibility into DR readiness further exposed the organization to operational gaps during critical incidents.
• Implemented a pilot-light DR architecture using AWS DRS across Mumbai (primary) and Hyderabad (DR) regions.
• Deployed EC2 web server, bastion host, ALB, and Amazon RDS in the primary region with private subnet isolation.
• Configured cross-region RDS read replica in Hyderabad for database failover readiness.
• Established VPC peering between regions with configured security groups and routing for seamless connectivity.
• Installed AWS Replication Agent on source servers to enable continuous replication to the DR staging subnet.
• Tested end-to-end failover by triggering recovery jobs, promoting RDS read replica to primary, and redirecting traffic to the DR region.
Achieved 15-minute RTO and 30-second RPO with cross-region DR, enabling non-disruptive drills, high availability, and resilience against outages and ransomware.
