Sizing, designing, and configuration is an integral and one of the most critical parts of any Exchange
deployment. Also, this step involves consideration of a lot of factors that would affect the performance
and functioning of the messaging infrastructure. The main idea behind writing this book was to put all
the related information in one place in a stepwise and easy to understand manner.
There are many articles regarding sizing and designing of Exchange messaging infrastructure
including information on how to use the brilliant tools (like ‘Exchange Role Requirement Calculator,
Processor Query tool, etc.) provided by Microsoft Exchange team. However, this information was
scattered. Also, there was no clarity about where to start, what information to look for and what other
components/ factors are involved and how to incorporate all that information in the designing and sizing
process.
I would also like to the point that though the primary target audiences of this book are people who
work on sizing, design, and implementation of Exchange messaging infrastructure or people who are
eager to learn the same; this book would prove to be equally useful to anyone who wants to understand
an Exchange solution from end to end. These guidelines are intended for users who have a strong
knowledge of Microsoft Exchange 2010, 2013 and 2016
