Anyone who owns the SQL® Server licenses for their organization will know that Microsoft® made a change to standardize on core-based licensing for the enterprise edition with the 2014 release in April.
For many this represents a change and introduces uncertainty about how core-based licensing will impact their environment and of course, costs. Many applications available today offer this kind of licensing for virtualized infrastructure. Whether an application is licensed by core or by CPU socket, the net result is the same, enabling you to effectively license an entire host and run as many instances of the application as you want on it.
The key to making these kinds of licensing models work for you is having the ability to optimize VMs placements in order to minimize the number of physical hosts that need to be licensed. This can be a big challenge for many organizations that don’t have an intelligent workload placement engine and instead rely on balancing tools like VMware® DRS® to place workloads. Many of the tools out there claim to offer licensing optimization and when in reality, they are really just tracking or containing the workloads to the existing number of licensed servers. This doesn’t help you with the core problem of how to reduce your license requirement – now.
Cirba has been helping our customers to safely minimize the number of licensed hosts by optimizing VM placements according to licensing requirements along with all other fit-for-purpose, utilization and technical requirements to:
- Optimize workload placements to both isolate licenses and increase VM density for the target license type. The net effect of this is an immediate reduction in the number of physical hosts requiring the licenses – on average 55%.
- Avoid future sprawl and contain VMs requiring those licenses to those hosts during rebalancing. Cirba also routes new VMs to the right environment and physical host considering its licensing requirements.
The impact of placing VMs this way on software licensing costs is significant. One recent analysis done for a customer for Microsoft® SQL® Server Enterprise Edition reduced the license requirement by a total of 400 physical hosts. That’s big dollars for any organization!
In fact, Cirba has saved organizations an average of 55% on licensing requirements for software packages like Microsoft® SQL® Server, Microsoft® Windows® Server, Oracle® database, IBM® Websphere®, and CA® Application Performance Management (Wily®). In an enterprise environment that translates to millions in software licensing savings.
