On-Premises Data Center & Disaster Recovery on AWS Cloud
Client Overview
A mid-sized Manufacturing company with a global presence faced challenges with outdated on-premises data center (DC) and disaster recovery (DR) infrastructure. The company sought a scalable, resilient, and cost-effective cloud solution to enhance performance, reduce costs, and ensure business continuity.
Business Challenges
- Legacy Infrastructure: Frequent downtime and inefficiencies due to aging on-premises hardware.
- High Operational Costs: Significant expenses associated with maintaining DC and DR infrastructure, including hardware, licensing, and operational support.
- Scalability Constraints: Inability to dynamically scale resources for high availability and failover readiness.
- Security & Compliance Requirements: Strict regulatory requirements demanding advanced security measures and disaster recovery capabilities.
- Remote Workforce Enablement: Ensuring secure access to critical applications and data in case of disasters or infrastructure failures.

Solution Overview
AWS Cloud for Data Center & Disaster Recovery
To address these challenges, a hybrid migration and disaster recovery strategy was implemented, leveraging AWS services for high availability and resilience.
1. Assessment & Planning
- Conducted a comprehensive infrastructure audit to evaluate on-premises DC and DR capabilities.
- Developed a cloud migration roadmap, prioritizing mission-critical applications and DR policies.
- Chose AWS EC2 for compute, RDS for database management, S3 for scalable storage, AWS Backup for DR, and AWS Managed Microsoft AD for directory services.
- Implemented AWS Landing Zone and Control Tower for governance and compliance management.
2. Hybrid Connectivity Setup
- Configured a site-to-site VPN and AWS Direct Connect for secure, low-latency communication between on-prem and AWS.
3. Primary Data Center Migration:
- Migrated applications and workloads using AWS Server Migration Service (SMS) and AWS Database Migration Service (DMS).
- Transitioned storage to Amazon S3 and EBS with lifecycle policies for cost optimization.
- Deployed AWS Managed Microsoft AD to extend authentication services securely.
4. Disaster Recovery Implementation:
- Configured AWS Elastic Disaster Recovery (AWS DRS) for real-time replication and failover.
- Leveraged Amazon Route 53 for DNS failover automation.
- Deployed AWS Backup for automated, policy-driven backup and restore capabilities.
- Implemented multi-region replication to improve resilience and data availability.
5. Security & Compliance Enhancements:
- Enforced AWS IAM, Security Hub, CloudTrail, and GuardDuty for access control, monitoring, and threat detection.
- Ensured compliance with financial regulations using AWS Artifact and Audit Manager.
6. Validation & Optimization
- Conducted DR testing, failover simulations, and workload performance validation to ensure recovery objectives were met.
- Fine-tuned AWS Auto Scaling policies for optimized resource allocation.
- Decommissioned legacy on-prem DR infrastructure after successful validation.
- Utilized AWS Cost Explorer and Trusted Advisor for continuous cost management and efficiency improvements.
Business Impact
- 50% cost reduction by eliminating on-prem DC and DR infrastructure and optimizing AWS resources.
- Improved resilience with multi-region AWS DR strategy and automated failover.
- 60% security enhancement with AWS-native security and compliance controls.
- 99.99% uptime achieved through high availability, disaster recovery automation, and failover mechanisms.
- Seamless remote workforce support with secure cloud-hosted applications and directory services.
Conclusions
By migrating its data center and implementing AWS-based disaster recovery, the enterprise achieved a secure, resilient, and cost-effective cloud infrastructure. The solution ensured business continuity, enhanced security, and improved operational efficiency with minimal downtime.
