Bank of America's CEO says it's saved $2B per year by building its own cloud
70000 servers in 23 datacenters – sounds awful. Why have it spread out so much?
350 million capex for 70k high end server DC setup may make sense.<p>$2B = 40% savings means their opex was $5B and now it's $3B. That is high expense. Guessing most of it is licensed software costs? Like Oracle on every single core?!?
