A project I’m working on for an approximately half-billion dollar company in the health care industry has forced me to revisit Hyper-V versus VMware after a long period of inattention on my part, and it has become apparent that Hyper-V has made significant progress as a viable platform for at least medium enterprises. My key takeaways include:
Hyper-V has come a long way and is now a viable competitor in Microsoft environments up through mid-size enterprise as long as their DR/HA requirements are not too stringent and as long as they are willing to use Microsoft’s Systems Center, Server Management Suite and Performance Resource Optimization as well as other vendor specific pieces of software as part of their management environment.
Hyper-V still has limitations in VM memory size, total physical system memory size and number of cores per VM compared to VMware, and VMware boasts more flexible memory management and I/O options, but these differences are less significant that they were two years ago.
For large enterprises and for complete integrated management, particularly storage, HA, DR and automated workload migration, and for what appears to be close to 100% coverage of workload sizes, VMware is still king of the barnyard. VMware also boasts an incredibly rich partner ecosystem.
For cloud, Microsoft has a plausible story but it is completely wrapped around Azure.
While I have not had the time (or the inclination, if I was being totally honest) to develop a very granular comparison, VMware’s recent changes to its legacy licensing structure (and subsequent changes to the new pricing structure) does look like license cost remains an attraction for Microsoft Hyper-V, especially if the enterprise is using Windows Server Enterprise Edition.
As a follow-up to my blog post yesterday, there’s another area that’s worth noting in the resurgence of interest in BC preparedness, and that’s standards. For a long time, we’ve had a multitude of both industry and government standards on BCM management including Australian Standards BCP Guidelines, Singapore Standard for Business Continuity / Disaster Recovery Service Providers (which became much of the foundation for ISO 24762 IT Disaster Recovery), FFIEC BCP Handbook, NIST Contingency Planning Guide, NFPA 1600, BS 25999 (which will become much of the foundation for the soon to be released ISO 22301), ISO 27031, etc. There are also standards in other domains that touch on BC, security standards like ISO 27001/27002.
And when you come down to it, several of the broad risk management standards like ISO 31000 are applicable. At the end of the day, the same risk management disciplines underpin BC, DR, security and enterprise risk management. You conduct a BIA, risk assessment, then either accept, transfer or mitigate the risk, develop contingency plans, and make sure to keep the plans up to date and tested.
In my most recent research into various BCM software vendors and BC consultancies, as well as input from Forrester clients, BS 25999 seems to be the standard with the most interest and adoption. In the US at least, part of this I attribute to the fact that BS 25999 is now one of the recognized standards for US Department of Homeland Security’s Voluntary Private Sector Preparedness Accreditation and Certification Program. The other standards are NFPA 1600 and ASIS SPC.1-2009. I’ve heard very few Forrester clients mention the latter as their standard.
During the last 12 to 18 months, there have been a number of notable natural catastrophes and weather related events. Devastating earthquakes hit Haiti, Chile, China, New Zealand, and Japan. Monsoon floods killed thousands in Pakistan, and a series of floods forced the evacuation of thousands from Queensland. And of course, there was the completely unusual, when for example, ash from the erupting Eyjafjallajökull volcano in Iceland forced the shutdown of much of Western Europe’s airspace. These high profile events, together with greater awareness and increased regulation, have renewed interest in improving business continuity and disaster recovery preparedness. Last quarter, I published a report on this trend: Business Continuity And Disaster Recovery Are Top IT Priorities For 2010 And 2011.
During Interop, I attended two sessions on disaster recovery and backup in the virtual world, topics that are near and dear to my heart and also top of mind for infrastructure and operations professionals (judging by the number of inquiries we get on those topics). First up was How Virtualization Can Enable and Improve Disaster Recovery for Any Sized Business which was very interesting (and very well attended). The panel was moderated by Barb Goldworm, President and Chief Analyst, FOCUS, and the panelists were: George Pradel, Director of Strategic Alliances, Vizioncore; Joel McKelvey, Technical Alliance Manager, NetApp; Lynn Shourds, Senior Manager, Virtualization Solutions, Double-Take Software; and Azmir Mohamed, Sr. Product Manager, Business Continuity Solutions, VMware.
Barb kicked off the session with some statistics on disaster recovery that can help people build the business case for it: 40% of business that were shut down for 3 days, failed in 3 years. She also cautioned that you have to test DR regularly and under unexpected circumstances.
