AWS Global Accelerator is the correct choice because:

• Static IP addresses: Global Accelerator provides static IP addresses that act as a fixed entry point for your applications, which is specifically mentioned in the question requirement
• Global availability: It uses the AWS global network to route traffic to optimal endpoints across AWS regions, improving availability
• Performance improvement: By using AWS's backbone network, it reduces latency and improves performance for global users
• Traffic management: It provides automatic failover between healthy endpoints, enhancing application resilience

While other services have their uses:

• Amazon CloudFront is a CDN for content delivery but doesn't provide static IP addresses
• Amazon S3 Transfer Acceleration accelerates uploads to S3 buckets
• Amazon API Gateway is for creating and managing APIs but doesn't provide the global traffic routing with static IPs
