Of course we did this, but cost is not the only consideration.<p>Frankly, CPU-hours and TB-years are still within 5-10% of the total cost providing sequencing results to the patients. What is really important is that the cloud allows us to determine exactly our cost-per-analysis without paying for excess capacity or maintenance.<p>What matters also is reliability, redundancy, and peak capacity, where the cloud (both Google and the other provider) win hands down.
