Global Accelerator
Overview
AWS Global Accelerator is designed to improve global network performance by offering entry point onto the global AWS transit network as close to customers as possible using ANycast IP addresses
- Anycast IP's allow a single IP to be in multiple locations. Routing moves traffic to closet location
- 2 anycast IP Addresses
- All location of global accelerator edge locations wil use the pair of anycast IP addresses
- Traffic initially uses public internet before entering a Global Accelerator edge location
- from the edge, data transits globally across the AWS global backbone network
- increases the performance substantially
