API Management Platforms

How'd,

It's cool I can now easily expose my app data to the world via a REST/SOAP/SAP API.
 
My issue is the platform doesn't support traffic control or throttling of queries per day/per second (malicious or accidental). I’ve read my paranoia can be put to rest (no pun indended) by using an external API Management Platform.
 
Can anyone recommend one or share their experience? (www.mashery.com, www.3scale.com …..)
 
Our case is likely to have 100’s of consumers with 1’000 of queries each per day.
 
Cheers
Steve

Hi Steve! 

I haven't come across this in real life, but there a number of people posting reviews of these products, namely analysts from Forrester or Gartner... 

Maybe someone else has experienced one of these platforms...

Cheers!
