Implementing AlwaysOn Availability Groups

AlwaysOn Availability Groups provide a flexible option for achieving high availability, recovering from disasters, and scaling out read-only workloads. The technology synchronizes data at the database level, but health monitoring and quorum are provided by a Windows cluster.

This chapter demonstrates how to build and configure availability groups for both high availability (HA) and disaster recovery (DR). We also discuss aspects such as performance considerations and maintenance. We discuss using availability groups to scale out read-only workloads in Chapter 16.
