An enterprise web application is hosted in the us-east-1 Region. Users located in Europe are experiencing high latency when accessing the application. At the same time, internal resources in the application VPC are unable to resolve the domain names of shared services hosted in a separate VPC. A Solutions Architect needs to optimize the network performance for global users and fix the internal resolution issues. Which of the following actions should the Solutions Architect take? (Select TWO.)
- Deploy AWS Global Accelerator to route user traffic over the AWS global network to the application endpoints.Answer
- Associate the Route 53 Private Hosted Zone of the shared services VPC with the application VPC.Answer
- CDeploy a single NAT Gateway in a single public subnet to handle all outbound traffic from the application instances across all Availability Zones.
- DConfigure AWS Transit Gateway using a Direct Connect Gateway for transitive routing between spoke VPCs without establishing Transit Gateway attachments.
- ESubmit a support ticket to request Application Load Balancer pre-warming to handle the standard baseline user traffic.
Answer
Deploying AWS Global Accelerator to route user traffic over the AWS global network, and associating the Route 53 Private Hosted Zone of the shared services VPC with the application VPC.
Deploying AWS Global Accelerator optimizes user access by onboarding traffic at edge locations near the users and routing it via the AWS backbone network, mitigating internet latency. Associating the Route 53 Private Hosted Zone with the application VPC ensures that resources within the application VPC can perform DNS queries for resources in the shared services VPC.
Step-by-Step Solution
Key Concept
Optimizing external user network performance using AWS Global Accelerator, and resolving internal cross-VPC DNS resolution using Route 53 Private Hosted Zones.
