Final answer:
To lower latency and improve transfer speeds for global users, Amazon CloudFront and Amazon Route 53 are the most effective AWS services. CloudFront is a CDN that delivers content with low latency by caching content closer to users, while Route 53 is a DNS service that routes requests efficiently through AWS infrastructure.
Step-by-step explanation:
The AWS services that can assist with lowering latency and improving transfer speeds for global users are Amazon CloudFront and Amazon Route 53.
Amazon CloudFront is a content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. It does this by caching content in edge locations closer to end-users.
Amazon Route 53 is a scalable domain name system (DNS) web service that routes end-user requests to infrastructure running in AWS, such as Amazon EC2 instances, load balancers, or S3 buckets, helping to improve performance and reduce latency through its global network of DNS servers.
Amazon S3, Amazon EC2, and Amazon RDS are foundational cloud services for storage, compute, and relational database needs, respectively. They are essential for application functionality but by themselves do not directly lower latency or speed up transfers for global users like CloudFront and Route 53 do.
