5. Hope for BuyIT.com; Cloud To The Rescue.

BuyIT.com's problem sounded complicated to resolve. Indeed using traditional methods it was going to be an expensive endeavor to say the least.

Luckily, Cloud Computing has mature solutions to their problems.

BuyIT.com, can contact Microsoft (O365), or Google (Apps), and purchase Enterprise email for their staff at the marginal cost of approximately 10$ per user per month, or $100 per user per year.

The only things they are going to need in order to start sending emails are a domain name (www.buyit.com), the PC's they already possess, and an internet connection at their offices which they also already possess.

• No Construction, 
• No laundry list of hardware of software to purchase. 
• No long list of technical staff to recruit and employ.
• No Capital expenditure of any kind.
• Technical support is provided on a 24/7/365 basis by Microsoft.
• No need to worry about backups.
• No need to establish redundancy offsite for disaster recovery.
• No need to worry about security.

I've got to tell you, that sounds simple and inexpensive to me. 

One call to Microsoft and you can be up and running within minutes, not days, weeks, or months.

Unlimited Scale-Ability, simply log into the website and purchase more users.

No further need to worry about patches and upgrades. With these types of SaaS services, those will always be the responsibility of the provider and seamless to the end users.

Sounds like a pretty compelling argument to leverage Cloud Computing in some business situations.
