    23. 23. Examples of usage<br />Resizable Compute Capability<br />
    24. 24. Examples of usage<br />SaaS<br />Your current CRM package is not managing the load or you simply don’t want to host it in-house….use a SaaS provider such as Salesforce.com<br />Your email is hosted on an exchange server in your office and it is very slow…outsource this using Hosted Exchange.<br />
    25. 25. Examples of usage<br />You need to host a large file (5Mb) on your website and make it available for 35,000 users for only two months duration.
