This solution is mostly being used to deliver flexibility, high availability, and redundancy to accommodate production demand on an as-needed basis.
The main driver is consolidation, which is then complemented with the above-mentioned items. Hyper-V is a cost-effective platform that helped many companies I've been involved with to reduce data center administration and licensing costs drastically.
Once the platform is in place, it helps to control resources more accurately and on a consumption basis. By using the VMM (Virtual Machine Manager) you have full control of the fabric, workloads, templates and many more resources. Running Hyper-V Core also increases security and reduces update time-frames, which also helped us to increase our uptime and overall service delivery expectations.
