AWS Global Accelerator

Introduction

AWS Global Accelerator is a networking service that improves the availability and performance of applications by providing optimized routing through AWS's global infrastructure. It accomplishes this by establishing endpoints that direct traffic through AWS network edge locations, bypassing much of the public internet infrastructure.

Key Features

AWS Global Accelerator can provide up to 20 static anycast IP addresses per accelerator.

Here are the key details:

• Each Global Accelerator gives you 2 static anycast IP addresses by default

Static IP Addresses

• Provides static public IP addresses for application endpoints

• These addresses remain constant even when underlying infrastructure changes

• Protected by AWS Shield by default for DDoS protection

Network Optimization

• Routes traffic through AWS's global network infrastructure

• Connects users to the nearest edge location

• Reduces latency by up to 60% compared to public internet routing

• Utilizes anycast IP addresses and BGP routing for optimal path selection

How It Works

1. Users attempt to access an application

2. Instead of traversing the entire public internet, traffic is directed to the nearest AWS edge location

3. Traffic then travels over AWS's optimized network infrastructure

4. Requests reach the application endpoint through a more efficient path

Common Use Cases

Public Applications

• Creates global static IP endpoints

• Directs traffic to the nearest edge location

• Improves global application accessibility and performance

Hybrid Networking

• Enhances VPN connection performance

• Provides a cost-effective alternative to Direct Connect

• Can connect to Transit Gateway for VPC routing

• Optimizes connections between on-premises data centers and AWS environment

Multi-Region Failover

• Supports endpoints across up to 10 regions

• Automatically routes to the nearest healthy endpoint

• Provides seamless failover during regional outages

• Maintains consistent IP addresses during failover events

Security and Protection

• Origin masking for enhanced security

• Built-in AWS Shield protection

• Helps protect applications from DDoS attacks

• Provides consistent security across global endpoints

Performance Benefits

• Up to 60% faster response times compared to public internet

• Reduced number of network hops

• Optimized routing through AWS infrastructure

• Improved global application availability

Technical Implementation

• Uses anycast IP addresses for edge location detection

• Implements BGP routing for traffic optimization

• Automatically routes to healthy endpoints

• Supports integration with AWS networking services

Best Practices

• Use for applications requiring global reach

• Implement for multi-region architectures

• Consider as a cost-effective alternative to Direct Connect

• Utilize for applications requiring DDoS protection
