- The perception that mainframes, such as IBM’s System z, are a dying platform built on old technology is applying pressure on IT leaders to determine the future viability of this platform and whether it’s still the right fit for their organization.
- Similarly, the high cost associated with a single mainframe creates negative perceptions and pressure to reduce those costs. Capacity-related licensing costs, in particular, have long been a sore point for IT leaders.
- A skills shortage, particularly for advanced mainframe skills such as system programming, is a critical concern for many companies.
Our Advice
Critical Insight
- Support for Linux and Windows on System z, as part of a hybrid computing model, has generated renewed interest in mainframes (e.g. 80 new mainframe clients between 2010 Q3 and 2011 Q3, and 86% year-over-year MIPS growth in 2011 Q2).
- Mainframe total cost of ownership (TCO) has historically been lower than the equivalent capacity in other platforms, such as commodity servers. The introduction of the zEnterprise 114 in 2011 at a lower price point (starts at $75K), further improves the TCO comparison. In addition, organizations are also leveraging specialty engines and sub-capacity reporting to reduce licensing costs.
- While there is a skills shortage, there is also an abundance of training available that is helping to address that issue (for example, over 150 universities and colleges offer mainframe courses). Similarly, key vendors in the mainframe market offer training.
Impact and Result
- If you are facing a resourcing crisis - or to prevent one - use the advice in this solution set to overcome a skills shortage.
- Use our TCO tool to properly evaluate your mainframe’s cost effectiveness, and then follow our recommended strategies for reducing mainframe costs and leveraging the mainframe to optimize your infrastructure to also reduce overall IT costs.
- If you’re considering moving off the mainframe, use this solution set to evaluate migrating off, using a hosting provider, or staying with the mainframe.
