In the past, the traditional method for purchasing application software was to purchase the application on a DVD from a local store or wait 3-4 days for it to be delivered from Amazon. At that time, you would have to pay $300—$400 for the software. With the evolution of the cloud, there is now a tendency to obtain your applications through subscription services, where you pay a monthly fee and can download the application immediately. Two examples of this are:

• Office 365: Office 365 from Microsoft, where you would not only get your email but you would also get Skype, SharePoint, and Office applications.
• Adobe Acrobat Pro: Adobe Acrobat Pro is one of the premier applications that allows you to create and modify PDF files.
