Introduction

This chapter covers the availability solutions offered by vCenter. We will look at configuring and tuning High Availability (HA) and Fault Tolerance (FT), reviewing different scenarios of using admission control, backup, and replication. You may be running vCenter with a trial license, which will work just fine if you decide to try some of these recipes.
