How Cirba Saved a Fortune 50 Bank $5.5 Million in Microsoft Windows Server Processor-based Licenses

An upcoming license renewal can be a blessing or a curse. Unfortunately for many organizations, it typically means ever increasing costs with environment growth for popular software packages like operating systems or databases. Below is the story of how one organization leveraged Cirba to actually reduce their licensing while still leaving room for required growth.

With a Windows Server Datacenter edition license renewal approaching, the bank saw a high risk for significant cost increases. The processor-based licensing model could enable the bank to take advantage of economies of scale and run more VMs per licensed physical host, saving the organization on Windows Server licensing. Unfortunately, the bank had no way to determine whether they really required Windows Server licenses for the 4000 physical hosts that were currently licensed. Not only that, the cost issue was about to be exacerbated with environment growth and potential further sprawl throughout the data center.

Cirba’s Software-Defined Infrastructure Control was chosen by the bank to address the issue. The Software License Control module is part of the solution’s Control Console and enables organizations to optimize VM sizing and placements considering all the utilization, technical, business and operational requirements including software licensing. The bank recognized the value Cirba brought in terms of balancing application demand with infrastructure supply to increase efficiency and agility while reducing performance and operational risk. Due to tight renewal timelines, Microsoft Server software licensing optimization became the top priority.

Within a few short weeks, Cirba was deployed and the analysis was completed to identify optimal VM placements, which significantly reduced the required Windows Server footprint in the environment. Cirba accomplished this by isolating the licensed VMs from those not requiring the licenses and maximizing the density of licensed components on physical hosts. By leveraging Cirba to control VM placements on an ongoing basis, the bank ensured Windows VMs were contained to the licensed physical servers.

The Results:

  • Using Cirba’s analytics the bank reduced its requirement from 4,000 to 3,400 licensed physical servers
  • The bank reduced its license requirement conservatively by just over 20% to allow for planned growth
  • The license savings totaled USD $5.5 million
  • The bank continues to use Cirba to automate VM sizing and rebalancing, ensuring continual risk mitigation, efficiency and software license optimization and containment.
