Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 647 discussion

Global Accelerator is a good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP, as well as for HTTP use cases that specifically require static IP addresses or deterministic, fast regional failover.

A - does exactly what is required Not B - Would rely on DNS caching (as it should not) Not C - CloudFront is not for VoIP Not D - ALB does not address any of the issues and would not support VoIP

automated failover across AWS Region + minimize latency -> Global Accelerator

VoIP ==> UDP ==> Global Accelerator.

AWS Global Accelerator: AWS Global Accelerator is a service that uses static IP addresses (Anycast IPs) to provide a global entry point for your applications. It routes traffic over the AWS global network to the optimal AWS endpoint based on health, geography, and routing policies. Health Checks: AWS Global Accelerator supports health checks, allowing it to route traffic only to healthy endpoints. This helps in achieving high availability and automated failover across AWS Regions.
