Additional Use Cases and Their Protocols
In this section, we are going to look at additional use cases for subscription services, routing, switching, and Active Directory.
Subscription Services and Their Protocols
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 advent and evolution of the cloud, you can now obtain your applications through subscription services, where you pay a monthly fee and can download the application immediately. Two examples of this are as follows:
- Office 365: Office 365 is from Microsoft, where you not only get email services, but you 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.
