Summary

In this first chapter, we had a look at the differences between availability and resilience, as well as an overview of the new architecture of Exchange 2013 and all the improvements it brings over the past editions of Exchange.

Throughout the following chapters, we will explore in depth about all these new availability and resilience features. We will see how to take full advantage of them through the design and configuration of a highly available Exchange 2013 infrastructure, starting with the CAS role in the next chapter.
