With this chapter's tried-and-true information, you can successfully install, configure, and administer a clustered instance of SQL Server 2014. In this chapter, you learn how a Windows Failover Cluster Instance (FCI) works, and whether it's the right solution for your organization. The newly adopted name is AlwaysOn Failover Cluster Instance as of SQL Server 2012, which is synonymous with Windows Server Failover Cluster. You learn how to choose between upgrading a previous version of a Windows Failover Cluster and building a new cluster; how to plan for clustering, including hardware and the operating system; and how to install SQL Server 2014 on a Windows Failover Cluster. Finally, you learn how to maintain and troubleshoot an operational instance of SQL Server on a cluster.
Although you can deploy a geographically dispersed cluster in Windows 2012 R2, this chapter primarily focuses on co-located clustering, as well as the most commonly deployed Windows Failover Cluster configuration.
