Phil Wainewright writes that: “Cloud is no place for amateurs”. He makes the case that recent outages at IBM and T-mobile run facilities proves that big companies overestimate their competence at SaaS and Clouds.
I do not see this as an issue of big versus small, I think it is a matter of how reliable and rugged a system you are able to construct. A small company or an Enterprise could create a reliable cloud with the right kind of fault tolerance built in.

Emotionally, incidents like these strengthen the argument for internal on-premises Clouds constructed using SOA Layer and VMWare based fault tolerance.
