First and foremost the biggest difference is that a GUAPPLE has a Linux operating system and an iSweep appliance has a Windows operating system, however the differences don't stop there. A GUAPPLE's purpose is to update the CU*Base GOLD software, where an iSweep appliance updates the CU*Base eReceipts and Photo ID capture software. Additionally, the iSweep appliance uploads all the documents created by the eReceipts and Photo ID capture software and acts as a layer of redundancy in the eDocuments environment.

Therefore, in consideration of the above, two separate appliances are required because of the following reasons:

• The software that performs these tasks requires two different operating systems
• The appliances have distinctly different roles
• It is preferential to distribute work load
• It avoids single points of failure
