I wrote a high-level overview of cloud hosting for SolTech:
What the cloud changes
Your local IT staff leaves the best practices to the experts who worry about security and patches fulltime. They still help with the setup of servers but focus more on the configuration and not the “build” piece as the cloud vendor can provide off-the-shelf configurations. This frees up your local IT staff to focus on support specific to your business.
There are some other specific advantages of the cloud infrastructure as well:
- Pay as you grow: Instead of paying in large 25K server purchases you pay as your needs increase slowly
- Geographic independence: Instead of one datacenter where you hope nothing happens you have increased fault tolerance and performance of multiple locations of your resources
- Easier deployment: Cloud vendors provide services that allow you to easily upgrade your services and rollback if there are issues
