Highly-Available, Global Traffic Managmement at Scale
summary
AWS Global Accelerator presents two static IPv4 addresses (optionally two IPv6) advertised via anycast from 104 PoPs, terminates client TCP at the edge to pipeline handshakes and claims ~60% throughput improvement, and is engineered for 4.5 nines when both IPs are used. Edge PoPs run two independent network zones with shuffle sharding and 4 BGP speakers per PoP moved into regions so route withdrawals shift traffic within minutes. Traffic management uses traffic dials and endpoint weights and preserves client IPs via encapsulation to VPC endpoints.
