In 2009, I tested the computing performance of 'M1 small' EC2 instances. At this time it was the cheapest EC2 instances available, at $0.10 per hour.

Now 'T2 Micro' instances are available at only $0.013 per hour. I wanted to test how they compare to the old instances in terms of raw computing power, so I'll run the same good old Unixbench! Unlike the previous generation, it provides only 'burstable' performance, T2 instances are for workloads that dont use the full CPU often or consistently, but occasionally need to burst to higher CPU performance.
