I have an Amazon account with ec2 instances. we have a client which we need to interact with using soap. However, Amazon only lets us run X about of queries, and then we can not issue more from that process. To be sure, we've created a simple module, which is constantly blocked after 30 attempts or less. this (very simple) module run without an issue on any local machine we tried, and always fail on any Amazon ec2 instance no matter the size. We use NodeJS for the web interface, and the test script is an independent script. Anyone got this error?
You're getting rate limited by the API you're hitting, not AWS. There's no mechanism in AWS that would do this, especially not after allowing some to go through first, and especially not after a mere 30 queries.
