Zorluk: OrtaHigh-Performing and Scalable Network Architectures

A company hosts a web-based educational portal on Amazon EC2 instances behind an Application Load Balancer (ALB) in the ap-northeast-1 Region. Users in South America are experiencing high latency and packet loss when accessing the portal over the public internet during peak hours. The solutions architect must implement a network architecture that minimizes latency, avoids public internet routing fluctuations, and provides a stable connection. Which solution should the solutions architect implement to meet these requirements?

  1. Deploy AWS Global Accelerator and register the Application Load Balancer as the endpoint. Direct the users to access the portal via the accelerator's static IP addresses.Cevap
  2. B
    Configure Amazon Route 53 with a latency-based routing policy to route the South American user traffic directly to the Application Load Balancer's DNS name.
  3. C
    Establish an AWS Site-to-Site VPN connection from the users' local networks to the VPC to bypass the public internet and automatically scale throughput.
  4. D
    Configure stateless Network ACLs on the public subnets to allow direct traffic to the EC2 instances, bypassing the Application Load Balancer to reduce network hops.

Cevap

Deploy AWS Global Accelerator and register the Application Load Balancer as the endpoint. Direct the users to access the portal via the accelerator's static IP addresses.
AWS Global Accelerator utilizes the AWS global network to route traffic from the edge location closest to the user directly to the Application Load Balancer. This avoids the public internet congestion, reduces latency, and decreases packet loss.

Adım Adım Çözüm

1
Analyze the user location and the host region to determine the source of latency.
Traffic from South America to the ap-northeast-1 Region (Japan) travels over multiple public internet service providers (ISPs), exposing it to routing fluctuations and packet loss.
Understanding the path of the network packets helps identify why public internet routing is suboptimal.
2
Evaluate AWS services designed to optimize global client-to-application traffic.
AWS Global Accelerator is selected because it ingresses traffic at the edge location closest to the user and routes it over the private AWS global network.
Using the AWS global network avoids the public internet and minimizes hops, jitter, and latency.
3
Associate the existing Application Load Balancer with the AWS Global Accelerator endpoint.
Traffic is routed efficiently from the global edge locations to the regional ALB.
This maintains the load balancing architecture while providing a high-performance network path.

Anahtar Kavram

AWS Global Accelerator optimizes network path performance for global users by routing traffic over the dedicated AWS global network instead of the public internet.
