AWS Disaster Recovery Implementation Project for Government Infrastructure
Overview
The AWS Disaster Recovery Implementation project focuses on establishing a robust disaster recovery solution for government infrastructure using AWS cloud services. This implementation ensures business continuity, data protection, and minimal service disruption through a comprehensive DR strategy covering 12 critical servers Including web and database servers.
Primary Goals and Objectives
- Implement a highly available disaster recovery solution for critical government services
- Meet compliance requirements for government operations
- Implement Secure VPN Tunnel between primary Data Center and AWS Cloud
- Ensure data protection and quick recovery capabilities
- Minimize downtime during disaster scenarios
Features and Functionalities
RTO/RPO Implementation:
- Recovery Time Objective (RTO) of 30 minutes achieved through AWS EDR service and pre-configured AMIs
- Recovery Point Objective (RPO) of >5 minutes maintained via continuous Block level data replication
- Regular testing and validation of recovery procedures
- Automated health checks and monitoring
Data Replication:
- Continuous data synchronization between primary and DR sites
Security Compliance:
- Implements government-grade security measures and compliance requirements
Monitoring & Alerting:
- Comprehensive monitoring using Zabbix and Grafana
Key Components
Production Environment:
- 12 On Premises servers for critical applications
