					Comparison of Google Apps
Premier Edition & Microsoft
Exchange Infrastructure
Introduction

Google Apps Premier Edition is Google’s Software as a Service (SaaS) solution for business
messaging, collaboration, and security. It includes Gmail, with integrated voice and video chat,
Google Calendar, Google Docs, Google Sites, and Google Video. Google Apps is a reliable, cost-
effective solution for keeping employees connected and improving their productivity.

Microsoft® Exchange Server is Microsoft’s on-premise solution for enterprise messaging. It includes
support for email, calendar, contacts, and tasks. It requires client software, typically Microsoft
Outlook®, to connect to these services. Microsoft Exchange is a mature product with a large installed
base across businesses of all sizes. The current version is 2007, but the previous version (2003) is still
in use and now there is new version Exchange 2010 which says you need 8 servers for ideal
implementation.

Remember 7 key differentiators when helping your customers compare Google Apps Premier Edition
and Microsoft Exchange Server 2003/2007: (1) initial investment, (2) maintenance, (3) uptime, (4)
collaboration, (5) security, (6) mobile access, and
(7) total cost of ownership.
