Businesses now need to run 24 hours a day, seven days a week, every single day of the year, and services must be kept online or customers will be lost. In today’s global marketplace, it is critical for these systems to always be available for companies to remain competitive and keep their users satisfied. Data center high availability can be achieved in several ways, but the most common and easiest is through the combination of server virtualization and failover clustering.
Failover clustering provides the very best high-availability solution for virtual machines (VMs) with fast and automated recovery, access to shared data and almost no downtime due to servicing. It offers high availability for planned downtime such as servicing, maintenance, upgrades, as well as for unplanned downtime, which could happen because of security threats, power outages or even natural disasters.
To learn more about it, read my whitepaper "Introduction to Hyper-V High Availability" introducing the scenarios, design considerations, features and best practices for keeping services online that are running on Microsoft’s virtualization and clustering platforms, Windows Server Hyper-V and Failover Clustering.
