Our approach & solution
enreap designed and implemented a secure On-Premises to AWS Disaster Recovery architecture, leveraging Amazon EC2 for the application tier and Amazon RDS for SQL Server for the database tier. The solution incorporated encrypted replication, controlled DNS failover, real-time monitoring, and structured DR drills to validate recovery objectives and operational readiness.
Site-to-Site VPN Connectivity
Enabled secure connectivity between the on-premises environment and the AWS Mumbai Region for reliable disaster recovery operations.
Highly Available Application Infrastructure
Deployed the application tier on multi-AZ Amazon EC2 instances to ensure resilience and high availability.
Managed Database & Secure Replication
Implemented Amazon RDS for SQL Server with KMS encryption, SSL/TLS, and SQL Server Log Shipping for secure, low-latency replication.
Controlled Failover & File Synchronization
Used GoodSync for continuous application file synchronization and Cloudflare DNS for controlled traffic redirection during DR events.
Monitoring, Governance & Compliance
Strengthened security and operational visibility through IAM least-privilege access, Amazon CloudWatch, AWS CloudTrail, and Amazon S3 for centralized backup and log storage.
