The $0.40 cost per day I calculated includes multi-AZ HA, and your bursts would have to be fairly significant to overwhelm two t2 instances which are accumulating CPU credits 95% of the time - say around 600 requests per minute for a few hours.<p>Of course, this is all conjecture since I can&#x27;t actually view your workloads, but we&#x27;ve been performing this exercise for our own services, and the t2 series of servers is remarkably capable: especially given their cost. The original administrators thought (or were lead to believe) that we really needed the raw horsepower that c*.large+ instances offer... and they didn&#x27;t in most cases.<p>Routers, crud API wrappers, even some disk persistance applications all qualify as &quot;non-CPU intensive&quot;.
