Final answer:
To reduce latency and costs, the company can use Amazon CloudFront, a content delivery network, to deliver content closer to US users. They can also set up global application load balancers using Amazon Route 53 to distribute workload across EC2 instances in the US region. By utilizing these services, the company can improve performance and user experience.
Step-by-step explanation:
To reduce latency for users in the US, the Japanese company hosting their applications on Amazon EC2 instances in the Tokyo Region can utilize Amazon CloudFront, which is a content delivery network (CDN). Cloudfront has edge locations in multiple regions, including the United States, which can reduce the distance data needs to travel, thereby improving latency for US users. By caching and delivering content from edge locations closer to the users, CloudFront can help minimize latency and provide a faster user experience.
Additionally, the company can consider setting up global application load balancers (ALBs) using Amazon Route 53. ALBs distribute incoming application traffic across multiple EC2 instances located in different regions. By distributing the workload and sending US user traffic to EC2 instances in the US region, the company can minimize latency and improve performance for US users.
By using a combination of CloudFront and global ALBs, the Japanese company can reduce latency for US users and provide a better user experience while minimizing costs.
