IT departments are starting to change the way they provide services to their users. We are seeing more adoption of SaaS delivery of applications and moving servers and storage to offsite providers like AWS, RackSpace, Drop Box, Box, etc. The reasons revolve around economics and flexibility. Lower to non-existent up front capital costs, lower cost of ownership and the ability to expand or contract compute and storage resources as needed, quickly and easily.
All of this change will have an affect on what IT related PS is delivered and how that delivery is made.
