Stefan over at EmailTide has a great article on hosted vs cloud based solutions for email. With services like Google Apps and Mobile Me increasing in popularity, migrating from a hosted enterprise solution to a “cloud based” one may seem more and more attractive, but as Stefan put it:

          “Last week’s outage at Google, recent repeat problems at Amazon’s S3 storage services and Apple’s “insanely grating” MobileMe launch highlight the need to carefully consider all aspects when weighing hosted vs. on-premise solutions.

Reliability is a big factor, but there is also the security aspect. Can you trust a large web service such as Google or Microsoft to keep your sensitive data secure? You really can’t be too careful in this regard-most companies share a large amount of confidential information via email.

Stefan lists 7 key issues you need to examine when considering moving your users into the cloud. It’s must reading for anyone wondering which solution is best for their business.
