If I am an AWS customer I expect AWS to handle/prevent DDoS, same way as they do with S3 to achieve 11 9's availability (the files are saved in multiple AZs in the same region - Glacier IIRC copy files on different regions to avoid data loss in case of physical disaster).
One of the reason for choosing AWS is because AMZ has deep pockets and has the means (financial and technical) to fight against large DDoS attacks, while a smaller provider might not have to do that. Putting clients in a position to have to buy that sort of protection doesn't sound very smart to me.
If you are an AWS customer you should have done your due diligence and know that amazon won't do a very good job at that.
Someone will always have the upper hand in an arms race, and it's not service providers yet. It's just a matter of finding the choke point between their transit and your code.
Well, the whole point of AWS is not having to deal with the usual hosting stuff. They'll naturally have lots of customers with high expectations and very little understanding of how things work in the background.
I see so many people confused about this. Eleven nines is their durability guarantee, their availability that they guarantee is only 99.99%
availability means you'll get your bits immediately.
Durability is the % of your data that doesn't die. Eleven 9s means that if you store 1TB on AWS S3 you can expect to lose 10 bytes and still be within SLA.
As a very simplified example, imagine they are expecting to lose 2 servers every day, this percentage might be the probability of those two servers storing the same exact object (and thus, losing it irretrievably).
i.e. you could expect to lose 10 bytes of your 1TB every year if your stored it as a trillion one byte objects, but if you stored it as a single object you could expect to lose the whole thing once every hundred billion years, but none of it the rest of the time.
Offtopic but relevant. One of my customer moved their email to O365 without understanding the differences from being ON-Prem. Now they are struggling to adopt their business processes to then limitations MS imposes.
If the attack is tiny, sure. Otherwise they'll just cut you off.
Yet they get to claim inexhaustible capacity.
Amazon might wave the fee, but you are the first party responsible.
