Which AWS services or features provide high availability and low latency by enabling failover across different AWS Regions?

Explanations:

Amazon Route 53 is a scalable DNS web service that allows for routing traffic globally and can direct users to different AWS Regions based on health checks and routing policies, enabling high availability and low latency.

Network Load Balancer operates at the connection level (Layer 4) and can distribute traffic across multiple targets within a single region but does not provide failover across different AWS Regions.

Amazon S3 Transfer Acceleration is designed to speed up file uploads to Amazon S3 using the Amazon CloudFront edge network, but it does not provide high availability or failover across regions.

AWS Global Accelerator is a networking service that improves the availability and performance of applications with users globally by directing traffic to optimal endpoints in different AWS Regions, ensuring low latency and high availability.

Application Load Balancer operates at the application layer (Layer 7) and is used to distribute traffic across multiple targets within a single region. It does not support cross-region failover directly.
