Hyper-V vs. vSphere…and the Winner Is Service Manager?

Posted on Updated on

I often get asked why I like Hyper-V or why I don’t like VMware. The answer, strangely, isn’t about technology. Anybody that knows me well, knows that I’m not a technology bigot. Meaning I don’t get fanatical about particular companies or pieces of technology. In my house we have six tablets. A Surface RT, a Surface Pro (soon to be replaced by a Pro 2), 3 Android tablets, and an iPad. They all get used on a regular basis. There is no favourite.  Just a preference for one device over the other based on the particular use case in question and the strengths of each device at addressing that use case. I’ve used VMware products for years and I like them. They have met many of the requirements I’ve had for a long time.

So how does this relate to Microsoft vs. VMware? Well, I see a lot of fanaticism over VMware. A large percentage IT Pros really love it and many are fanatical about it. They are quick to criticize alternatives (like Hyper-V) without having all of the facts. Another issue is that most people see the results of past consumption and mistake it for current market trends. Let me explain that with an example. Currently Android phones outsell iPhones however, most people see more iPhone sin use that Android phones because iPhones have been around longer have had past sales success. What is being seen is phones that were purchased over the last several years still in use.

Enough digressions. Back to Microsoft and VMware. Historically, VMware has had the edge over Microsoft in the hypervisor market. With Hyper-V 3, most experts would agree that the gap has narrowed enough that for most organizations, the differences are insignificant from a pure technical capabilities perspective. It’s like choosing between a Honda and a Toyota. Both vendors have offerings in every major segment. Most consumers would be equally well served by a Camry or an Accord but preferences still abound. In the virtualization world, there are many other factors to consider such as migration costs, retraining, new licensing, etc. VMware has had very strong technical offerings for a long time and the investments made by many organizations can’t easily be shifted. Of course, historically, there are many examples of a technically superior product being eclipsed (BetaMax vs. VHS, Amiga vs. PC, FLAC vs. MP3). It also isn’t about first or early movers in a market. Consider Blackberry losing 33% market share in 2012 while Android now has nearly 80% market share in the smartphone market. Of course, depending on when you read this the current market share may be very different.

So back to my previous statement “It isn’t about technology”. I’ve shown examples of a superior product losing out as well as examples of an early mover with a dominant market position being eclipsed by a relative newcomer. If not technology, what’s it about then?

Well, I’m an IT Pro. Any IT Pro worth his salt will tell you that the three key elements of a successful IT rollout of any system are People, Process, and Technology. Not necessarily in that order, but all three ingredients are required for success.

As I’ve mentioned previously, VMware has great technology and Microsoft is no slouch either. We can remove people from the equation since both Microsoft and VMware have access to the pretty much the same talent pool and really, the people that matter most aren’t the vendor’s staff but the enterprise customers’ datacenter staff. So a talented VMware administrator could easily be a talented Microsoft administrator. Using the same logic, you might conclude that the processes that are used in enterprise datacenters would also be a wash between VMware and Microsoft implementations and for the most part you’d be right. However I believe Microsoft has an edge. Here’s why:

Microsoft has a long history of supporting cloud/online services that process billions of transactions a year. Consider Hotmail/Outlook.com, XBOX Live, Office 365, Azure, as a few examples with revenue Microsoft has had to develop some fairly robust processes for managing their datacenters. This isn’t new for Microsoft. Consider the ITIL based Microsoft Operations Framework (MOF) currently at version 4.0 has been around since 2000. VMware doesn’t have an online services history to learn the hard lessons of datacenter management or the history of helping customers manage their datacenters from a process perspective. Microsoft has taken the battlefield tested processes they’ve used for over a decade and incorporated many of them into one of the newer and lesser known products in the System Center suite, Service Manager.

Service Manager helps organizations align business processes with technology delivery to create efficiencies in service delivery. The product is tightly integrated with the rest of the system Center suite (especially products like Operations Manager, and Configuration Manager) as well as Active Directory.  The rich CMDB provided by Service Manager helps to manage the inevitable VM sprawl that accompanies virtualization.  It is also  a great platform to bolt on a  SAM/ITAM solution like the one from Provance (Full disclosure:  Provance is headquartered a few kilometres from my homeand I know many of their staff professionally – We’ve worked on joint projects and I’ve had more than a few drinks with them over the years.).

Until VMware has a similar offering, organizations that want to enable IT Service Management (ITSM) best practices, will find it much easier with a Microsoft private cloud solution than with a VMware solution.

BTW – Market share numbers for last year shows an interesting trend in the hypervisor adoption rates:

Are we in the midst of a Blackberry like decline for VMware?

VMware ESX vs. ESXi

Posted on Updated on

VMware shops weigh ESX vs. ESXi

Some interesting quotes fromthe article:

“People that have never done anything with VMware are all going with ESXi,” said Singler. “Unless they need special hardware monitoring or have existing scripts, there’s no reason not to go with it.”

“Enterprise ESXi shops say the lightweight hypervisor offers many advantages over the full-blown version. In terms of security, ESXi’s smaller footprint and lack of Linux service console makes it harder for hackers to tamper with or for administrators to make mistakes on.”

“VMware’s made no secret of the fact that the ESX console is going to be end-of-lifed,” Wolf said. So while it’s still there in vSphere 4, “I’d be surprised if it was still there in version 5. Customers are going to have to plan on that in the next 24 to 36 months.” Part of that planning process is to select management tools that already support ESXi.”

Most interesting quote:

“We have made no secret of the fact that ESXi is the preferred and better architecture.

Vice-President of Product Marketing, VMware Inc.

Hyper-V vs. VMware: Which is cheaper?

Hyper-V vs. VMware: Which is cheaper?.

A few key quotes from the article:

“So while VMware’s initial acquisition cost is much higher than Hyper-V’s, VMware allows for much denser VM configurations and permits RAM overcommit for higher memory utilization rates”

“…users interested in Hyper-V today tend to be small and medium-sized businesses and remote offices that already use Windows Server; Hyper-V is built into that familiar system and allows them to run hundreds of VMs at a lower cost than VMware…”

“large data centers that are serious about VM availability and density continue to rely on VMware, not the first version of Hyper-V”
