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.
AWS Disaster Recovery Implementation Project for Government Infrastructure
Overview
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
- Automated health checks and monitoring.
- Monitoring & Alerting:
Comprehensive monitoring using Zabbix and Grafana
- Regular testing and validation of recovery procedures.
- Data Replication:
Continuous data synchronization between primary and DR sites
- Security Compliance:
Implements government-grade security measures and compliance requirements
