Topic 1 Question 208
An online retail company is running a web application in the us-wast-2 Region and serves consumers in the United States. The company plans to expand across several countries in Europe and wants to provide low latency for all its users.

The application needs to identify the users’ IP addresses and provide localized content based on the users’ geographic location. The application uses HTTP GET and POST methods for its functionality. The company also needs to develop a failover mechanism that works for GET and POST methods and is based on health checks. The failover must occur in less than 1 minute for all clients.

Which solution will meet these requirements?
- Configure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the NLBs in each Region.
- Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the ALBs in each Region.
- Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create Amazon Route 53 public hosted zones that have failover routing policies.
- Configure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an Amazon CloudFront distribution. Configure an origin group with origin failover options.

  HTTP req, A&D out. Global Accelerator is closer to the user; it can react faster than Route 53.

- 正解だと思う選択肢: B
  Option A: While NLBs are performant, they are better suited for TCP rather than HTTP/HTTPS traffic. Option C: Route 53 might not meet the sub-minute failover requirement due to DNS propagation delays. Option D: CloudFront is more suited for static content, not necessarily for dynamic applications requiring HTTP GET and POST failover.
  
  Option B : ALB: Specifically designed for HTTP/HTTPS traffic and provides features like path-based routing and host-based routing. AWS Global Accelerator: Ensures low latency by routing traffic to the optimal region and provides quick failover mechanisms with health checks.
