Cost and Operational Load in Numbers

The marketplace's three schedulers cost 14,000 dollars a month in cloud infrastructure: 6,000 for A, 5,000 for B, and 3,000 for C. One scheduler sized for the midnight peak would cost about 8,000 dollars a month. The saving is 6,000 dollars a month, or 72,000 dollars a year.

Many proposals stop at that number, and it is the smaller part of the cost. The three schedulers also interrupt their on-call engineers about 9 times a week. They need about 15 hours a week of manual work, and about 30 engineer-days a quarter of upgrades
