What should a solutions architect do to meet these requirements?
Use AWS Global Accelerator with health checks.
Use Amazon Route 53 with a geolocation routing policy.
Create an Amazon CloudFront distribution that includes multiple origins.
Create an Application Load Balancer that uses path-based routing.
Explanations:
AWS Global Accelerator improves the availability and performance of your application by routing user traffic to the optimal endpoint based on health checks and latency. It automatically redirects traffic to healthy endpoints in different AWS Regions, ensuring low latency and high availability without relying on IP address caching.
Amazon Route 53 with a geolocation routing policy can direct users to the nearest endpoint based on their geographic location, but it does not provide the same level of automated failover and health checks across AWS Regions as Global Accelerator. Additionally, it may not handle real-time changes in endpoint health as effectively.
Amazon CloudFront is primarily a content delivery network (CDN) and while it can improve latency for static content, it is not designed for real-time VoIP applications or automated failover across multiple AWS Regions. It also does not directly manage the health of backend services for VoIP calls.
An Application Load Balancer with path-based routing is useful for directing traffic based on URL paths but does not provide global failover across AWS Regions or optimize for latency like AWS Global Accelerator. It is typically used within a single region, limiting its effectiveness for global applications.
To the best of my knowledge, the answer is:
Use AWS Global Accelerator with health checks.
Based on what I know, the answer is:
Use AWS Global Accelerator with health checks.
