AWS Global Accelerator

What is it?​

A service that improves the availability and performance of your applications using the AWS global network, offering static IPs and intelligent routing.

What is it for?​

Optimize global traffic routing, reduce latency, and improve availability for applications distributed across multiple AWS regions.

Use Cases​

  • Global application distribution
  • Multi-region load balancing
  • Traffic migration between regions
  • Disaster recovery
  • Gaming and real-time applications
  • Media streaming

Key Points​

  • Static IPs: Provides fixed global IP addresses
  • Intelligent Routing: Latency-based optimization
  • Health Checks: Continuous endpoint monitoring
  • Automatic Failover: Redirection in case of failures
  • Security: AWS Shield integration
  • Multi-Region: Support for endpoints in different regions

Comparison with Traditional DNS​

  • AWS Global Accelerator: Offers optimized routing on the AWS network, global static IPs, and automatic failover in seconds.
  • Traditional DNS: Relies on DNS propagation (which can take minutes or hours), doesn't offer network layer routing optimization, and has limitations for quick failover.
