The client, a leading banking institution based in Gabon, Africa, aimed to enhance their operations by building a new core banking application. Their goal was to establish a reliable infrastructure that combined the benefits of an on-premises data center for primary operations and a Disaster Recovery (DR) solution hosted on AWS.

The client required a robust and scalable hybrid infrastructure to:

• Host the new banking application in their on-premises data center.
• Ensure a reliable Disaster Recovery (DR) environment on AWS.
• Maintain real-time synchronization between the on-premises data center and AWS DR.
• Secure communication between the two environments through VPNs and firewalls.

We implemented a hybrid infrastructure solution to meet the client’s requirements:

1. On-Premises Data Center Setup:

• Configured the on-premises data center remotely, including:
• Firewalls and VPNs for secure access and connectivity.
• Switches and Servers for efficient networking and compute resources.
• Virtualization to enable flexibility and scalability for the new application.

2. AWS DR Implementation:

• Deployed a highly available DR environment using AWS services:
• EC2: For scalable compute instances to host the application in the DR environment.
• EFS & S3: To store application data securely with high durability and availability.
• Elastic Load Balancer (ELB): To ensure high availability and distribute traffic during failover scenarios.
• Auto Scaling: To automatically adjust resources during DR activation.
• Amazon RDS: For a managed and scalable database solution.
• Site-to-Site VPN & Custom VPN Gateways: To establish secure, low-latency connectivity between the on-premises data center and AWS.

3. Real-Time Synchronization:

• Configured data replication to ensure the on-premises data center and AWS DR remain in sync in real-time, providing seamless failover capabilities.

4. Support and Monitoring:

• Implemented ongoing monitoring using AWS CloudWatch and other tools to track performance, uptime, and security.
• Delivered 24/7 support and maintenance, ensuring the infrastructure remains optimized and secure.

After the project implementation, the client achieved:

• • High Availability and Reliability: The hybrid solution ensures uninterrupted banking operations with seamless failover to AWS in case of disruptions.
  • Scalability: The AWS DR environment automatically scales to handle load spikes during emergencies.
  • Real-Time Synchronization: The on-premises and AWS DR infrastructure maintain real-time data synchronization, ensuring zero data loss.
  • Enhanced Security: VPNs, firewalls, and custom gateways ensure secure communication between the two environments.
  • Operational Efficiency: The client now benefits from a modern, scalable banking application with reliable DR capabilities.
