  • Deployment phases: Gradually increase traffic to new deployments to monitor performance.
  • Recovery scenarios: Limit traffic to an endpoint recovering from an outage to prevent overload.

To adjust the traffic dial, you simply specify a percentage that represents the amount of traffic to be directed to the endpoint group.

Endpoint Weights

Endpoint weights provide a mechanism to adjust the proportion of traffic sent to each endpoint within a group. This is beneficial when you want to:

  • Balance loads unevenly: Send more traffic to endpoints with higher capacity.
  • Conduct A/B testing: Route different amounts of traffic to test different versions of your application.

You assign a numeric weight to each endpoint, and AWS Global Accelerator distributes traffic proportionally based on these weights.

By utilizing these traffic flow management tools, you can ensure that your applications are not only highly available but also deliver consistent performance.

Health checks in AWS Global Accelerator

AWS Global Accelerator is designed to monitor the health of your application endpoints and route traffic only to healthy ones.

Here’s a detailed look at how health checks work within AWS Global Accelerator:

  • Endpoint Monitoring: AWS Global Accelerator continuously checks the status of each endpoint. When you add an endpoint to an accelerator, it must pass a health check to start receiving traffic.
  • Health Check Protocols: The service supports TCP, HTTP, and HTTPS protocols for health checks, ensuring that it can interact with a wide range of application types and confirm their operational status.
  • Automatic Health Checks: Health checks are performed automatically and regularly to ensure that traffic is not routed to failed or degraded endpoints.

  • Custom Routing Accelerators: It’s important to note that health checks are not used with custom routing accelerators, as these accelerators allow you to specify the exact destination for your traffic without automatic failover.

By leveraging AWS Global Accelerator’s health checking capabilities, you can ensure that your application remains available and responsive to your users, even in the face of individual endpoint failures. This contributes to a robust and reliable global application infrastructure.

Client IP Address Preservation

AWS Global Accelerator provides a way to improve the performance of your applications by optimizing the path that user traffic takes through the AWS global network. An important feature within this service is the preservation of client IP addresses. This feature is crucial for applications that require visibility into the original source IP for security measures, analytics, or application logic.

When using AWS Global Accelerator with an internet-facing Application Load Balancer (ALB) as an endpoint, client IP address preservation is enabled by default. This means that the source IP address of the client is preserved and passed through to the ALB, allowing the backend services to see the original IP address of the client.

For Network Load Balancer (NLB) endpoints, client IP address preservation can be enabled on a per-endpoint basis. This allows the backend services, such as EC2 instances, to receive the original client IP address, which can be used for processing client-specific logic or for maintaining client affinity.

Here are some key points about client IP address preservation in AWS Global Accelerator:

  • Default Behavior: For new ALB endpoints, client IP preservation is enabled by default.
  • Per-Endpoint Configuration: For NLB endpoints, client IP preservation can be enabled or disabled based on your application needs.
  • Source IP Visibility: Preserving the client IP address allows backend services to apply logic based on the client’s location or other IP-based attributes.
  • Security and Compliance: Knowing the client’s original IP address can be critical for security logging, compliance, and implementing IP-based access controls.

It’s important to note that for endpoints that do not have client IP address preservation enabled, the IP addresses used by the Global Accelerator service at the edge network will replace the client’s source IP address. This could impact applications that rely on the source IP for decision-making processes.

By leveraging client IP address preservation, AWS Global Accelerator ensures that your applications can maintain the benefits of client-specific processing while also enjoying the performance improvements provided by the service.

Terminating TCP connections from clients

AWS Global Accelerator enhances application performance by terminating TCP connections at the AWS Edge location nearest to the client. This feature is pivotal in reducing latency and improving the user experience for globally distributed applications. Here’s how it works:

  • Edge-Based Termination: When a client initiates a TCP connection, AWS Global Accelerator terminates this connection at the edge of AWS’s network, which is geographically closer to the user than the application’s endpoint. This reduces the distance that the initial TCP handshake has to travel, thereby decreasing setup time.
  • Performance Improvement: By handling the TCP termination at the edge, AWS Global Accelerator can improve client-to-endpoint performance by up to 60%, as the AWS global network is optimized for low-latency, high-throughput, and high-reliability data transfers.
  • Automated Routing: After the termination of the TCP connection at the edge, AWS Global Accelerator automatically routes the traffic to the most performant AWS origins in different Regions and/or Availability Zones.

The termination of TCP connections at the edge is a significant feature for applications requiring high performance and low latency. It is particularly beneficial for services that are accessed by users from various geographical locations.

Idle Timeout

AWS Global Accelerator is designed to optimize the path that user traffic takes to your application, improving performance and availability. An important aspect of this service is how it handles idle connections, specifically through the idle timeout setting.

Idle timeout refers to the period of inactivity after which a TCP connection is considered idle and can be terminated by AWS Global Accelerator. According to some sources, the default idle timeout for TCP connections in AWS Global Accelerator is 90 seconds. This means that if no data is sent or received over a connection for this duration, the connection could be closed.

Here are some key points to consider regarding idle timeout:

  • Default Timeout: The default idle timeout is set to ensure that resources are used efficiently, without maintaining unnecessary connections.
  • Adjustable Timeout: Depending on your application’s needs, you might need to adjust the idle timeout setting. This can be particularly important for applications that have long-lived connections with sporadic traffic.
  • Keep-Alive Messages: Implementing TCP keep-alive messages can help prevent connections from being closed prematurely due to the idle timeout.

It is essential to configure the idle timeout setting appropriately for your use case to maintain the desired level of connection persistence.

Remember, the proper management of idle timeout settings can contribute to the overall performance and reliability of your applications using AWS Global Accelerator.

The Role of Static IP Addresses

AWS Global Accelerator enhances the performance of your applications by providing static IP addresses as a fixed entry point for your users globally. These IP addresses are anycast from the AWS edge network, ensuring that user requests are routed to the nearest and most optimal endpoint.

Key Benefits of Static IP Addresses

  • Consistent Entry Point: Static IP addresses provide a consistent entry point for your applications, regardless of changes in the backend infrastructure.
  • Anycast Routing: The anycast capability of the static IP addresses allows for intelligent routing of user traffic to the nearest available endpoint, which can significantly reduce latency.
  • Simplified DNS Management: With static IP addresses, you can avoid the complexities of managing DNS records for multiple endpoints.
  • Enhanced Reliability: By default, AWS Global Accelerator offers two static IP addresses to ensure high availability. If one IP address becomes unavailable, the other can continue to serve traffic.

How Static IP Addresses Work

When you create an accelerator in AWS Global Accelerator, you receive two static IP addresses. These addresses are announced from multiple AWS edge locations around the world. As a result, when users send requests to these IP addresses, AWS Global Accelerator routes the traffic to the closest edge location, which then forwards the traffic to the most optimal endpoint based on performance, health, and configured policies.

Use Cases for Static IP Addresses

  • Global Services: For services with a worldwide audience, static IP addresses ensure that users have a consistent and reliable way to access your application.
  • Performance-Critical Applications: Applications that require low latency can benefit from the anycast routing of static IP addresses, which minimizes the distance data has to travel.

AWS Global Accelerator’s static IP addresses are a powerful feature for optimizing the performance and reliability of your applications. By leveraging these addresses, you can provide a better user experience for your customers around the globe.

How to use traffic dials and endpoint weights

AWS Global Accelerator enhances the performance of your applications by intelligently routing traffic to the closest AWS region and, subsequently, to the most optimal endpoints within that region. To fine-tune this routing behavior, AWS Global Accelerator offers two powerful features: traffic dials and endpoint weights.

Traffic Dials

Traffic dials allow you to control the flow of user traffic to different AWS regions. By default, traffic is directed to the region nearest to your users for the best performance. However, you can adjust the traffic dials to:

  • Redirect traffic away from regions that are over capacity.
  • Perform maintenance on a region without affecting your service’s availability.
  • Gradually increase traffic to a newly added region.

This functionality is particularly useful for managing global traffic during peak loads, maintenance windows, or when scaling out to new regions.

Endpoint Weights

For more granular control within a region that has multiple endpoints, you can assign weights to each endpoint. Endpoint weights dictate the proportion of traffic that each endpoint will receive. This is especially useful for:

  • Load balancing traffic across multiple Network Load Balancers, Application Load Balancers, or Elastic IPs.
  • Implementing A/B testing or blue/green deployments to roll out new application changes safely.

By adjusting endpoint weights, you can ensure that a specific endpoint does not become overwhelmed with traffic and that users experience consistent performance.

To implement these features, you can follow these steps:

  1. Access the AWS Global Accelerator console.
  2. Select your accelerator and navigate to the endpoint group you wish to configure.
  3. For traffic dials, adjust the percentage to control the amount of traffic directed to the region.
  4. For endpoint weights, assign the desired weight to each endpoint within the group.

Remember, the traffic dial is set to 100% by default, which means all traffic is routed to the endpoint group. Adjusting the dial down will proportionally reduce the traffic to that group.

By leveraging traffic dials and endpoint weights, you can optimize the performance and reliability of your applications on AWS, ensuring that your users always have the best possible experience.
