how large traffic can ddos shield defend? 500Gbps offen occurs in games industry.

I think specific numbers are hard because of the varying types of DDoS attacks and nuance in how they are conducted. Vendors are hesitant to make very specific promises about those numbers.

The real answer is that average DDoS attacks are still far lower than 500 Gbps. (Google search "average size of DDoS attack" and comb through several recent reports and analysis). I've seen 150 Mbps to 5 Gbps reported as an average size.

A 2.3 Tbps attack was reportedly mitigated by shield.. You can find reports about this on several news sites.

I can't find any official numbers or limits in AWS Shield documentation. Again, likely because of nuance in how these attacks are conducted and customer's specific configurations.

Hey! DDoS shields can vary in capacity, but many services offer protection well above 500 Gbps, especially for the gaming industry. I’ve dealt with similar issues while working with Baddies Hub, and it’s crucial to choose a robust provider that can handle large-scale attacks. Always check their specs or reach out to support for specifics!

As per public documentation:

"Shield maintains DDoS mitigation systems at all points of ingress from the internet. When Shield detects a DDoS attack, for each point of ingress, it reroutes the traffic through the DDoS mitigation systems in the same location. This doesn’t introduce any observable additional latency, and provides a mitigation capacity of more than 100 TeraBits Per Second (Tbps) across all AWS Regions and all edge locations."
