VMware vs. Microsoft is the hot debate in virtualization these days, but what about proprietary vs. open source hypervisors?
Forrester Research has an interesting take on that topic. The firm’s new report, “Are Open Source Hypervisors Viable for You?” says the recession will drive more businesses to consider open source virtualization. I’m not sure I agree.
In most other technology markets, the “open source is free/cheap, and more people want free/cheap things when the economy is bad, so more people want open source” argument holds up. But to paraphrase Allen Iverson, we’re talking about virtualization! Not other markets. Not other markets. We’re talking about virtualization!
Ever notice that when you talk to someone about virtualizating, it always seems to come down to, “So, what’s your consolidation ratio?” Everyone seems to care only about the number of virtual machines you can house on a single host system. While consolidation ratios are important, they’re yesterday’s news!
Virtualization is about so much more than just shrinking the footprint (physical and carbon) of your data center. Think about it: What does virtualization really do for you? It encapsulates your workloads (servers) into a collection of files that are consistent, that are portable, that are uncoupled from hardware, and that can be copied from location to location. Let’s look at each of these benefits individually:
You may have heard this morning that Oracle acquired Sun Microsystems. Like Ron Burgundy, it’s kind of a big deal.
Most of the early reaction to the news has focused on the fallout in the database market. Oracle, the market leader, now owns the biggest thorn in its side, Sun’s open source MySQL.
But the real legacy of the Oracle-Sun acquisition could be its effect on the virtualization market — particularly on VMware.
Bricks (standard rack-mount servers) are a known entity. You’ve been buying and deploying them forever. You are comfortable with bricks.
Blades (blade servers) are cool. They’re small. They look really neat in your rack. Your vendor really wants you to buy blades.
The question is, which platform is right for your virtual infrastructure? I’m here to say that, for the majority of environments, blades are the right answer. Why’s that, you ask? Well, it’s really pretty simple. Virtualization is all about simplifying your environment. It’s about having consistency in platform and in process/procedure. It’s about rapid provisioning and rapid recovery from failures. It’s all about commoditizing your IT infrastructure to enhance support to your line of business applications.
There has been a lot of mud slinging and FUD raising among virtualization vendors lately as the quest to rule the virtualization space continues.
One vendor will release information about its product, comparing performance, pricing or features to another vendor, with the other vendor firing back with its own response shortly thereafter. With all this going on, who are you to believe if you are in the market to adopt a virtualization solution in your own environment?
Comparisons by vendors themselves are always biased; after all, they want you to buy their product and not a competitor’s. Performance comparisons between vendors — even by third parties — don’t always tell the big picture and can be difficult to interpret.
I’ve been involved in many data center virtualization projects and one thing that continues to amaze me is that, far too often, the senior management team has no way of knowing if the project is a success. Oh sure, the manager of the data center is thrilled! He’s got only 10% of the systems he had before the project began — but what does that mean to the CxO? Absolutely nothing!
The CxO doesn’t care how many servers are in the data center. He doesn’t care if those servers are running below 10% utilization. He couldn’t care less that there are now only 500 network cables rather than the original 15,000. He doesn’t even really care that the cost of power and cooling has been slashed by 75%. In the grand scheme of things, all those savings amount to a few decimal points in the overall corporate budget. If you want to get your CxO excited, you need to demonstrate that you’re favorably impacting something that he does care about — his line of business applications.
VMware and its supporters have made like Mr. Burns and released the hounds on Microsoft.
The object of their ire is the “Top 10 VMware Myths” video, which features two Microsoft execs trying (sometimes a little too hard) to show why Hyper-V is better than VMware. Viewers on Microsoft’s own site called the video “embarrassing” and said “we deserve better than this,” but that criticism pales in comparison to reaction on other blogs.
The award for Most Thorough Response goes to VMware’s Mark Chuang, who posted a 2,500-word rebuttal on the VMware Virtual Reality blog. Check out some of these zingers:
Microsoft has taken its virtualization marketing push and kicked it up a notch — BAM! — but it may be doing more harm than good.
The company’s new “Microsoft Mythbusters: Top 10 VMware Myths” video aims to dispel VMware’s claims about how good its own products are and how much Hyper-V stinks up the joint. Some viewers see it differently, however. They say Microsoft is in no position to talk and that smugness-tinged videos like this one are “embarrassing.”
I have to admit that I have been less than kind when it comes to Oracle’s virtualization software and licensing policies; I’ve written articles about their stubborn refusal to support their customers who use VMware, user frustrations with their licensing policies, and their unsubstantiated performance claims about Oracle VM being three times faster than other server virtualization software.
But, the newly released Oracle Enterprise Manager 10g Release 5 (10gR5) includes a VM Management Pack for Oracle VM that gives people using Oracle VM competitive features like high availability, lifecycle automation and application relationship management, making it a more attractive virtualization option.
Oracle’s Xen-based hypervisor runs on x86-64 Intel- and AMD- based systems and can support any operating system that runs on those platforms. Oracle officially certifies Linux and Microsoft Windows to run as a guest OS. The Oracle VM management tool (Oracle VM Manager) comes in the form of a Web-based interface that manages virtual server pools and performs tasks like live migrations.
The Oracle VM Management Pack 10gR5 gives users a way to manage their physical and virtual environments from one console. Some features include diagnostics of whether a problem is due to an application component, a virtual machine or physical resource issue and built-in configuration management that gives IT a way to track application relationships and analyze configuration changes.
The new management pack also lets you assign specific policies for virtualization, automated deployment through Oracle VM Templates for packaged applications, middleware, database, and Oracle Enterprise Linux. There are also lifecycle automation features for testing, deployment, patching and maintenance capabilities, including automated patching of operating systems and Oracle software running inside the guest VMs.
Lastly, Oracle VM users can now get high availability with new features that allow for server pooling, automatic load balancing and server failover. Many analysts say high availability is an absolute necessity when it comes to virtualization, so it’s great that Oracle decided to add that feature.
Perhaps I should start considering Oracle VM a contender in the virtualization market, especially against Microsoft Hyper-V, which doesn’t even have live migration yet. Or maybe not. Either way, it is an option.
If you run a ton of Oracle apps and you want to give Oracle VM a shot, it is free to download form their website. Oracle VM support per two-socket server costs $599, and includes access to software and updates through the Unbreakable Linux Network and 24X7 support. Oracle VM Premier Support costs $1,797 per two sockets for three years, and includes network access plus 24×7 support.
Ever since I learned last summer that VMware had leased a massive 100,000 square feet of data center space along the Columbia River in East Wenachtee, Wash., I’ve always assumed that they would eventually become a cloud computing provider, and not just a provider of the underlying cloud infrastructure software. Turns out I was wrong.
At a lovely dinner for press and analysts at L’ecrin in Cannes tonight, I had the pleasure of speaking with VMware’s CIO Tayloe Stansbury, who assured me that the company has no designs on becoming a cloud provider. Not that they didn’t consider it. But the more they thought about it, the more they came to the conclusion that it would be reckless to compete with their partners (folks like Savvis, T-Systems and Terremark), Stansbury said.
So what are they doing with that ginormous data center in East Wenachtee? Testing and development, pure and simple. “It’s one of the ironies of being VMware that we have to develop our code on physical hardware,” Stansbury said. In order to assure that ESX can effectively virtualize workloads on any x86 system, VMware’s R&D must test the code against every conceivable server and storage platform. These days, all that hardware is being shipped to East Wenachtee, where it runs on electricity that costs two cents per kilowatt hour, versus the 20 – 30 cents per kilowatt hour VMware pays for power in the places like Palo Alto and Cambridge, Mass.
So I stand corrected (it won’t be the first time). Going forward, I hope VMware decides to share further details about its new data center.
