Final answer:
To reduce latency and add automatic failover, a solution architect should recommend implementing Amazon Route 53 for DNS routing and failover, as well as AWS Global Accelerator to optimize traffic routing, combined with a multi-region deployment of the application resources for high availability.
Step-by-step explanation:
To reduce internet latency and add automatic failover across AWS regions, a solutions architect should consider implementing a multi-region approach, leveraging services such as Amazon Route 53 and AWS Global Accelerator. Route 53 provides DNS services that can route users to the nearest region and perform health checks on the endpoints, redirecting traffic in case of failure. AWS Global Accelerator improves application performance by directing user traffic to the nearest AWS edge location and then leveraging AWS's backbone network for optimized routing to your application endpoints in different regions.
- Implement Amazon Route 53, a scalable and highly available Domain Name System (DNS) web service, to manage traffic across various regions through geographic DNS routing and active-active or active-passive failover configurations.
- Use AWS Global Accelerator to minimize latency by routing user traffic through the AWS global network infrastructure.
- Design the application to be region-agnostic by decoupling dependencies and ensuring that it can handle region failovers seamlessly.
These solutions should be combined with well-architected multi-region deployments of your application resources using services like Amazon Elastic Load Balancing (ELB) to ensure high availability and resilience against regional outages.
