We are, for SPM <http://sematext.com/spm>.  On c1.medium instances, I

* Jetty receiving tens of thousands of metrics per second (in batches, so
the rate of HTTP requests is lower than that number_
* Kafka brokers
* ZK instances

So far we have not had issues with this. Knock on wood.  Disk IO is not
high, nor is the CPU usage.
