The Register concluded: The ongoing rash of data leaks caused by misconfigured clouds is the result of companies having virtually no visibility into how their cloud instances are configured, and very little ability to audit and manage them.

I’ve written several times about “cloud” availability/reliability. A recent article on Microsoft’s outlook.com service brought this back to my attention. This is Microsoft’s free service so there’s not really a lot of room to complain. This discussion is to compare the cloud solution to a self-hosted solution.
