The article talks about some of the pitfalls of not having a SLA and
potential considerations you need to take into account to minimize the
risks of adopting cloud as an extension of your IT shop.
It should also be noted that the Cloud Standards Customer Council
(http://www.cloud-council.org/) just launched a new work group to
develop the Service Level Agreement Cookbook. This effort will be a
deep dive into the elements of a SLA and to provide an example of a
SLA for use by both cloud consumers and cloud providers.
