The service functions as a sophisticated traffic director that dynamically guides user requests along the most efficient and reliable paths. Below is a comprehensive overview of the step-by-step processes that take place when a user connects to your application through AWS Global Accelerator.

Initiation of User Traffic Through Static IPs

Every interaction with AWS Global Accelerator begins when a user sends a request to your application via one of two globally anycasted static IP addresses provided by the service. These IP addresses remain constant, offering a fixed entry point that simplifies DNS configurations, firewall rules, and client-side integrations.

These static addresses are announced from multiple AWS edge locations across the globe using Border Gateway Protocol (BGP). This allows the user’s traffic to be directed to the edge location closest to their physical location—reducing latency from the very beginning of the connection journey.

Entry via the Closest AWS Edge Network Location

Once a user initiates a request, the traffic is routed into the AWS network through the nearest edge location. AWS maintains hundreds of edge sites strategically distributed across major metropolitan and internet exchange hubs. These entry points act as the digital gateways into the AWS global backbone network.

This proximity ensures that user traffic exits the public internet and enters AWS-controlled infrastructure as early as possible in its journey. Doing so not only minimizes exposure to congestion and volatility in public networks but also enhances predictability, reliability, and speed of delivery.

Intelligent Selection of the Optimal Application Endpoint

After entering the AWS global network, the user traffic is evaluated and dynamically routed to the most suitable backend endpoint. This selection process is based on multiple real-time metrics, including:

The physical distance between the user and each potential endpoint
The health status of application instances, as determined by automated health checks
The configured traffic weights and routing policies set by the application owner
The current performance statistics and network latency conditions across paths

This performance-based decision-making process ensures that every user session is connected to the best available resource, reducing round-trip delays and optimizing throughput.

Direct Transmission Through the AWS Global Backbone

Once the optimal application endpoint has been identified, user traffic is transmitted through AWS’s highly optimized global fiber backbone. Unlike traditional routing over the unpredictable public internet, this path remains entirely within the secure and monitored AWS infrastructure.

Traffic is encapsulated, directed, and delivered to the appropriate endpoint group in the chosen AWS Region—such as an EC2 instance, an Application Load Balancer, or an Amazon ECS service. Since the entire transmission occurs within AWS’s private network, users benefit from reduced jitter, lower latency, and minimal packet loss.

This approach is particularly beneficial for mission-critical services, where even minor disruptions in transmission can lead to negative user experiences or operational risk.

Ongoing Dynamic Routing Based on Live Performance Insights

AWS Global Accelerator doesn’t simply direct traffic once and forget it. The service continually monitors the health and performance of all registered endpoints using both active and passive checks.
