Hmmmm this story from Basemap and 37Signals in the cost of Cloud is really interesting to me. When I left Facebook™ I left with an internal post asking and discussions:

At what point or what scale does “Cloud” become too expensive.

The answer to this question may vary depending on your use-case / needs; but even at small-scale like running a home lab / mini dc like I do, the cost of cloud is insane (mostly in storage for me, but the compute would be kind of nuts too).

Remember kids:

Cloud™ is not cheaper.
