Which AWS service would enable the company to improve the availability and performance of its applications?

Explanations:

Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations for faster access but does not provide static IP addresses or improve availability directly for all applications.

AWS Global Accelerator improves the availability and performance of applications by routing traffic through the AWS global network, providing static IP addresses that can be used for global applications.

Amazon S3 Transfer Acceleration speeds up the transfer of files to and from Amazon S3 but does not enhance application performance or provide static IP addresses.

Amazon API Gateway manages and scales API calls but does not provide static IP addresses or directly improve the overall availability and performance of applications.
