Licensing in Virtual Environments – Six Steps to Containing Costs

In licensing terms, virtualisation can be an untamed beast.

Yes, you can save money with virtualisation, reduce power costs, air conditioning overheads and floor space in expensive data centres – but the licensing bill for a virtual environment can be horrendous if not configured appropriately.

I spoke with Andrew Harcourt managing consultant at Holme Rose Consulting who specialise in Software Asset Management programs for large organisations. Here he offers his advice for companies looking to license virtual environments appropriately and offers six steps to containing costs;

“Companies need to take into account licensing at the outset”

1. Seek Advice – Don’t shy away from virtualisation as a strategy but make sure you pass the project through a SAM sanity check before proceeding. There are significant benefits to virtualising large parts of the data centre & desktop over and above the direct cash ones mentioned in your introduction. In a large enterprise the move from rigid physical environments to more agile & flexible virtual environments is very significant.

However, project teams need to think about how they are going to manage and maintain the virtual environment on an ongoing basis and whilst software licensing is but one part it is one that could push any virtualisation programme from cash benefit to cash liability.

The worst case scenario is for an organisation to re-buy original unconsolidated hardware because the virtual environment ends up being so expensive in licensing terms. An effective SAM program will help an organisation assess which applications are worth considering for easy virtualisation and those that will require commercial support from Procurement teams to deliver the most cost effective licensing terms. A simple factory production line for applications that are to be virtualised is the best solution.

2. Double Check Inventory – Many discovery tools quite simply fail to inform adequately what is happening in virtual environments, they are not as good as they should be. Tools need to get under the hood of a virtual host and find out not only the configuration of the physical host but also the configuration of the virtual machines themselves. Many existing tools simply state ‘This is your hardware and you have VMware installed’. You need to be more thorough and check the configurations of the virtual machines.

3. Soft or Fixed Partitions – You also need to be very careful about whether the virtual machines have soft or fixed partitions. What are the boundaries of the resources being made available by the hypervisor to those virtual machines / servers?

A large engineering client we have worked with recently focused all of their efforts on making their virtual environment work, with no consideration of the licensing implications. The client used soft partitions, which means the virtual servers in use contract & expand based on demand. The applications that they had deployed had licensing models based on what hardware COULD be used rather than actual usage and the client ended up having a very expensive solution. On this occasion we engaged successfully with the publisher to obtain some flexibility in their terms, however it is much better and cheaper to do this work at the start of the project.

Similarly for Citrix, not only do you need to know the hardware & software profile to establish that Citrix is installed but you also need to know what applications are published to the user. How many users are applications published to? Can they have more than one session of the application open at a time? How is access to groups restricted?

4. Expect Greyness From Software Vendors – Software vendors have anxieties about loss of revenues in the current climate so expect more audit activity. However the growth in the economy is limited and companies are looking to do more with less. Any ambiguity regarding licensing in virtual environments is in the vendors favour enabling them to exploit uncertainty and maximise revenue.

5. Be Pragmatic – No company is ever going to be 100% compliant in a virtual environment, it is about putting the right portfolio of management tools in place, having the right information to hand, managing a pool of licensing and reviewing it regularly. With some applications, set boundaries rather than fixed levels, a pool of entitlement that can flex with the business and importantly discuss via vendor / supplier management teams your medium and long term infrastructure plans with your key publishers.

6. ROI – Software Asset Management is unfortunately mainly seen as just protection from vendor audits, but it IS very much more than that. Deployed properly it WILL deliver significant savings. In January this year Computer Weekly detailed seven strategies to survive the recession, Virtualisation was at number one and Software Asset Management was at number two….
