AWS Global Accelerator

AWS Global Accelerator is a service that improves the availability and performance of your applications with global users. It provides two global static IP addresses that act as a fixed entry point to your application endpoints in AWS, helping you optimize routing and enhance the performance of your network traffic.

Key Features

• Global Static IPs: Provides two static IP addresses that act as a fixed entry point to your applications, making it easier to manage and route traffic.
• Improved Performance: Optimizes the path to your applications by routing traffic through the AWS global network, reducing latency and improving performance.
• Health Checks and Failover: Monitors the health of your endpoints and automatically routes traffic away from unhealthy endpoints to healthy ones.
• Traffic Dialing: Allows you to control the percentage of traffic routed to different endpoints, providing flexibility in traffic management.
• Integration with AWS Services: Works seamlessly with AWS services such as Amazon EC2, Elastic Load Balancing, and Amazon S3.

Architecture Overview

The following diagram illustrates how AWS Global Accelerator improves application performance and availability:

• Global Static IPs: Provides a fixed entry point to your application.
• Global Network: Routes traffic through the AWS global network to optimize performance.
• Endpoint Monitoring: Monitors the health of your application endpoints.
• Traffic Management: Routes traffic to the best performing endpoints based on health checks and routing policies.

Use Cases

• Global Applications: Improve the performance and availability of applications with global users.
• Disaster Recovery: Ensure high availability and failover capabilities by automatically rerouting traffic to healthy endpoints.
• Traffic Management: Control the distribution of traffic across multiple endpoints to manage load and optimize performance.
• Content Delivery: Enhance the performance of content delivery applications by routing traffic through the AWS global network.

Integration with Other AWS Services

AWS Global Accelerator integrates with several AWS services to provide a comprehensive solution for improving application performance and availability:

• Amazon EC2: Route traffic to EC2 instances across multiple regions.
• Elastic Load Balancing (ELB): Distribute traffic to multiple load balancers for improved performance and availability.
• Amazon S3: Improve the performance of content delivery for S3-hosted content.
• AWS Lambda: Route traffic to Lambda functions for serverless application deployments.
