This advanced atelier focuses on designing a robust multi-region disaster recovery (DR) architecture using AWS Transit Gateway, VPC, and complementary services. Participants will create an enterprise-scale architecture that ensures high availability, scalability, and optimal cost efficiency. You'll integrate services for cross-region data replication, automated failover using Route 53, and design considerations for latency optimizations. Through a series of tasks, you will implement real-world DR solutions that can withstand regional failures without data loss while minimizing downtime. This atelier prepares you for solutions architect roles where designing for failure is key, leveraging AWS's global infrastructure designs. By the end of this atelier, you will have built a production-ready multi-region DR environment, understanding the intricacies of multi-region networking, resource sharing, and cross-region failover mechanisms.
Your company, TechCraft Inc., is a multinational enterprise with a critical e-commerce platform. To ensure continuous delivery of services especially during a regional outage, the CTO has mandated the implementation of a multi-region disaster recovery (DR) solution. The primary requirements are: achieve a Recovery Time Objective (RTO) of less than 15 minutes and a Recovery Point Objective (RPO) of no more than 5 minutes. Additionally, the business needs cost-effective use of AWS resources to maximize the current cloud budget. To meet these requirements, you'll use AWS Transit Gateway for inter-region network connectivity, Route 53 for managing DNS failover, and S3 Cross-Region Replication for data storage. Analyze latency metrics to ensure minimal service interruption and perform exercises to automate failover processes.
