The so-called "E"DOS is easy to solve. Just re-negotiate your contract
with the cloud service provider to exclude that traffic from your bill.
After all, if the cloud security provider's security is great, they
shouldn't have a problem giving their customers credit for those
problems which the cloud solves. No more "E" problems for thec customer,
the DOS risk is shifted to the service provider. But now the service
provider still needs to solve the same problem.
Oh, the cloud service provider won't negotiate, won't give you unlimited
service credits, want to charge extra for that protection, don't want to
make promises it will work, and so on :-)
The same unsolved problems from the 1970's mainframe/timesharing era still
haven't been solved with virtualization/cloud/etc.
