I'm not even that familiar with ASM but my concerns about using Akamais solution (which I've only briefly looked at) would run along these lines;
1) This solution wouldn't protect against DDoS attacks directly targeted at you if the attackers discovered your 'origin' IP addresses
2) I'd imagine your ability to build, test and customise your security policy will be limited as would your abilities in relation to responses to attacks
3) Your costs are not fixed
4) Are you really happy to 'outsource' your security, who is responsible if it fails?
I'm sure someone better informed than me where security is concerned will also provide some input.
