Zorluk: ZorOptimizing Network Performance and Latency

An enterprise SaaS company has a multi-region application deployed in us-west-2 and ap-northeast-1 behind Application Load Balancers (ALBs). Users in Asia are reporting high latency and connection instability when connecting to the application's public endpoints. Additionally, the company's on-premises data center in Tokyo is connected to the ap-northeast-1 VPC via an AWS Direct Connect (DX) connection with a Private Virtual Interface (VIF) to a Virtual Private Gateway (VGW). The Solutions Architect must optimize global network performance, reduce latency for end-users, and enable transitive routing from the on-premises data center to both the ap-northeast-1 and us-west-2 VPCs. Which two actions should the Solutions Architect take to meet these requirements?

  1. Deploy AWS Global Accelerator and associate the regional ALBs with the accelerator to route client traffic over the AWS congestion-free global network.Cevap
  2. Create an AWS Transit Gateway in both regions, peer the Transit Gateways, and connect the on-premises Direct Connect connection via a Transit VIF to a Direct Connect Gateway attached to the Transit Gateways.Cevap
  3. C
    Associate the Direct Connect Gateway directly with the Virtual Private Gateways (VGWs) of both VPCs using the existing Private VIF to enable transitive routing between the on-premises data center and both regions.
  4. D
    Set up a Route 53 Resolver Inbound Endpoint in the ap-northeast-1 VPC to resolve the database domain names without associating the private hosted zone with the ap-northeast-1 VPC.
  5. E
    Consolidate all outbound traffic through a single NAT Gateway in each region to minimize routing hops and rely on standard ALB scaling to handle instant, massive traffic spikes.

Cevap

The correct actions are to deploy AWS Global Accelerator to route client traffic over the AWS global network and to establish peered AWS Transit Gateways in both regions connected to the on-premises Direct Connect link via a Transit VIF and Direct Connect Gateway.
Deploying AWS Global Accelerator optimizes end-user latency by routing traffic over the private AWS global network instead of the public internet. Setting up peered AWS Transit Gateways in both regions connected via a Transit VIF to a Direct Connect Gateway enables scalable transitive routing between the on-premises network and both VPCs.

Adım Adım Çözüm

1
Address client-side network latency and instability.
Deploy AWS Global Accelerator to onboard client traffic from Asia onto the AWS global network close to the users, bypassing the congested public internet.
Global Accelerator uses Anycast to route traffic to the nearest AWS edge location and then over the high-speed AWS backbone to the regional ALBs.
2
Address hybrid connectivity and transitive routing requirements.
Implement peered AWS Transit Gateways in us-west-2 and ap-northeast-1, and attach them to a Direct Connect Gateway using a Transit VIF.
Transit Gateway supports transitive routing between peered regions and on-premises networks, which standard VGW associations with Direct Connect Gateways do not support.
