I have an Elastic Load Balancer (ELB) on Amazon Web Services under DDoS attack (specifically a SYN flood) that Amazon has said occasionally hit over 2.4 million packets per second. While it hasn't taken the site down, it has been marginally effective at occasionally taking out a single ELB instance (there are 6-12 instances in the load balancer group) over the last week.
My obvious thought is- how bad is that level of traffic? Should I consider deploying my own load balancer solution on EC2 if ELB can't handle this much traffic? Or is this a pretty significant attack and would you say they are doing a pretty good job of mitigation?
