/me aerospike employee here - we did a live demo of running aerospike server on AWS EC2 during the fifth elephant last weekend at bangalore. The demo had 1M TPS and latency for 80/20 load (80% read, 20% write) was <1ms for >99.8% of queries.

This demo was done on 4 r3.4xlarge nodes - We did earlier runs on r3.2xl as well with similar results.

I didnt do a latency screenshot grab but those who saw the demo can comment..
