In a pre-cloud world you want cpu utilization. In a post cloud world you cou utilization high. The mindset doesn’t seem to be shifting… I’d bet their cpu utilization is sub 10%<p>> Reserved Instances and committed usage, as part of a Private Pricing Agreement," he wrote. "This is a highly optimized budget."<p>Maybe the commitments are optimized, but definitely not the compute as they are running RoR
No matter what ends up said about the reasons, blaming vendors is a bad sign. AWS pricing is formulaic, and being “shocked” by it is an admission of being asleep at the wheel.
Could you estimate cost savings with a faster language rewrite?<p>Based on the programming language energy usage benchmark, Java is 32x faster than RoR.<p>Let's say you could you replace 32 instances with Java, that might help with the reserved instance coat as well.
