The cloud is changing the paradigm behind enterprise class software by offloading the responsibility for the infrastructure to someone else. In the case of Office 365, that someone else is none other than Microsoft. Microsoft has invested heavily in building out data centers, installing computers, operating systems, backup systems, and maintenance plans.

Microsoft takes care of it all. When you use Office 365, you simply sign up and start using the products over the Internet. The result is that you don’t have to worry about the heavy lifting. You are free to focus on using the software instead of worrying about keeping the software running.

You have probably heard the expression that “it takes an army” to do something. When it comes to Information Technology, this saying rings true. When you start thinking about all the people and resources responsible for enterprise class software, the results can be mind-boggling.

You need networking people, operating system administrators, e-mail administrators, server administrators, domain administrators, DNS people, web developers, programmers, provisioning experts, backup engineers, infrastructure, maintenance, patches, backup generators, and the list goes on and on. It is no wonder that it used to take a very large company to adopt software, such as SharePoint.
