I guess its not exactly news that software companies are embracing the cloud, and its impact shows up in small but telling ways. I was looking at a set of projections one of my clients sent to us and one small expense line stood out. It was a $250 monthly charge increasing by $250 in about four-month increments. The $250 was what it cost him to fire up another virtual server at Amazon as his SaaS client base grows by a few hundred subscribers. Now think back a few years, or if youre old enough think back 30 years or so to the time-sharing days, and consider how you used to plan for datacenter growth.
