I can only talk for AWS, not GCP or Azure, but there are services that can help mitigate DDOS attacks: Shield (https://aws.amazon.com/shield/ https://aws.amazon.com/shield/) is AWS's DDOS protection service. It's free and is basic protection against L3/4 attacks. Shield Advanced (same URL as above) is a big step up in price, but gives you access to 'improved protection' and a global response team. Cloudfront (https://aws.amazon.com/cloudfront https://aws.amazon.com/cloudfront) is a CDN with global edge locations. WAF (https://aws.amazon.com/waf https://aws.amazon.com/waf) is AWS's web application firewall service. It's less about DDOS and more about specific application attacks, but is part of the whole solution. For more detail, you can have a look at AWS's DDOS whitepaper: https://d0.awsstatic.com/whitepapers/Security/DDoS_White_Paper.pdf https://d0.awsstatic.com/whitepapers/Security/DDoS_White_Pap...
