David Greschler, Microsoft’s director of virtualization and cloud computing, has left the company.
Greschler and Douglas A. Brown of the popular virtualization site DABCC.com have founded a new virtualization and cloud community site, PaperShare. Greschler is CEO, and Brown is CTO.
I have a note into Microsoft asking who the new director of virtualization and cloud will be. Amy Barzdukas, a general manager for Microsoft’s Server and Tools Business, will have at least some role; she’s the company’s designated Hyper-V executive for press briefings at next month’s Worldwide Partner Conference. Barzdukas joined Microsoft in 1997 and has previously worked on consumer security and Internet Explorer.
Greschler was the co-founder of application virtualization vendor Softricity, which Microsoft acquired in 2006. During his time as director of virtualization and cloud, Hyper-V debuted and emerged as the number-two server virtualization platform — albeit a very distant number two — behind VMware.
PaperShare allows users (and vendors) to share white papers they think their friends and colleagues may be interested in, and it also includes social media aspects such as status updates, groups and messages. For more information, check out this interview with Greschler and Brown from VMblog.com.
UPDATE (3:15 p.m.): Edwin Yuen will replace Greschler as Microsoft’s director of virtualization and cloud strategy. Yuen also joined Microsoft as part of the Softricity acquisition, and he’s been another public face of Hyper-V over the past several years.
Pop quiz: Why did you buy your particular smartphone or tablet?
A. Because of its cool apps that let me make dinner reservations, hail a taxi to the restaurant and then watch ESPN while I’m in said taxi.
B. Because of its remote-desktop capabilities.
Chances are, you just answered A (or some variation of it). People buy mobile devices for the apps. Sure, they use their remote-desktop features, but only because it’s easier to carry an iPad all day than it is to lug around a laptop. (And because you look a lot cooler if you have an iPad.)
Everything being equal, people would rather run Windows applications natively than log into a remote-desktop app, spend five minutes figuring out how to double-click on an icon and then hope the WiFi doesn’t cut out.
Pop quiz part 2: What does this have to do with the virtualization market?
B. More than you’d think. Read on…
VMware and other remote-desktop middlemen keep trying to insert themselves into the mobile conversation with their clients for smartphones and tablets. This plays into VMware’s prediction of the death of the traditional operating system. The idea is that VMware’s virtual infrastructure technologies and cloud-based applications, along with the proliferation of mobile devices, will break IT free from the chains of Windows, allowing users to be more independent and more productive. (It will also really, really complicate enterprise device management, but they usually leave that part out.)
The departures of XenSource founders Simon Crosby and Ian Pratt from Citrix have generated plenty of buzz in the virtualization market today, with all eyes focused on the company’s next move.
Partners note that the bulk of Citrix’s XenServer product development and marketing machine remains intact.
“Considering that both [Pratt] and [Crosby] are primarily advocates and evangelists for virtualization/open source projects and the heavy technical lifting is done by the Citrix developers, I don’t think this will mean any changes to the XenServer product commitment by Citrix,” wrote Shannon Snowden, consulting partner with Citrix partner New Age Technologies in Louisville, Ky., in an email. “Additionally, if the new company solves the security concerns with cloud infrastructures, then Citrix will be a big beneficiary, so it’s a win-win departure for everyone involved.”
XenSource co-founders Simon Crosby and Ian Pratt are leaving Citrix Systems to tackle their next project: cloud security.
Crosby, Citrix’s CTO, wrote today on his blog that he and Pratt, a Citrix vice president, will be co-founders of a new cloud security startup called Bromium. Bromium remains in stealth mode, but Crosby hinted at its direction in his post:
I remain firmly of the view that virtualization can offer a new toolset that can help to deliver a more secure and trustworthy computing infrastructure. … We are fusing deep virtualization and security systems DNA to build a powerful set of tools that can offer continuous endpoint protection.
Gaurav Banga, the creator of Phoenix Hyperspace, is another co-founder of Bromium, whose investors so far include Andreessen Horowitz, Ignition Partners and Lightspeed Venture Partners. George Kurtz, worldwide CTO and executive vice president at McAfee, is a board member.
Crosby wrote that he and Pratt “will remain active in our stewardship, contribution to, and promotion of the key building blocks of open infrastructure: xen.org, OpenStack.org, OpenVSwitch.org, the Open Networking Foundation and other projects.” He also emphasized that Bromium “does not intend to compete with any virtual infrastructure or security vendor.”
Crosby and Pratt joined Citrix when the company acquired XenSource in 2007. In a statement, Citrix said, “While we will obviously miss their day-to-day presence as employees here at Citrix, we’re genuinely excited about the Bromium vision and believe it will address some much needed industry challenges that are highly complementary to the Citrix virtualization, networking and cloud strategy.”
Celebrities occasionally evolve beyond what made them famous. A great example is Jesse Ventura, who went from professional wrestling villain to governor of Minnesota. But others aren’t so lucky. Just look at Eddie Murphy’s singing career.
The same can be said for IT vendors. Apple grew from a fledgling computer maker to the world’s largest technology company by capitalizing on the iPod, iPad and iPhone. And now VMware is trying to pull off a similar transformation, using its core virtualization business to make inroads in other markets, such as business applications and cloud computing.
It’s too early to tell if these moves will pay off, but early indications show that VMware is getting its cloud message out there, according to the SearchCloudComputing.com 2011 reader survey. When asked, “Which vendors do you most associate with private cloud computing?” an overwhelming majority of the survey’s 500 respondents named VMware. (Google was a distant second, just edging out Salesforce.com and Amazon.)
These results are a testament to VMware’s marketing machine, which constantly reminds us that VMware is not just a virtualization company. It feels like every week VMware purchases another company, and each acquisition is an opportunity for VMware to point out, “Hey, we do cloud!”
PCI DSS 2.0 clarified that credit-card-handling organizations could, in fact, use server virtualization. But the question still remained: How, exactly?
A new information supplement from the Payment Card Industry (PCI) Security Standards Council attempts to answer that question. The supplement, produced by a PCI special interest group consisting of more than 30 merchants, vendors and security assessors, identifies the challenges of virtualizing PCI-regulated environments and advises organizations on how to implement virtualization in compliance with the Data Security Standard (DSS).
The summer hypervisor season is in full swing, and three blockbusters are capturing the attention of fans and critics alike. We already know about the upcoming releases of VMware vSphere 5 and Citrix XenServer 6.0, and now word on Microsoft Hyper-V 3.0 has leaked out, too.
French publication PC INpact reported last year that the next version of Hyper-V would be part of the Windows 8 operating system, and that indeed appears to be the case. Early this morning, Windows Now blogger Robert McLaws posted several screenshots of what he said is a leaked Windows 8 x64 build, which show Hyper-V as a feature that users can turn on or off through the control panel.
(The name of the next version of Hyper-V isn’t set in stone anywhere; PC INpact called it “Hyper-V V3” in its report last year, but McLaws went with “Hyper-V 3.0,” although none of his screenshots use that name. We’ll stick with that for now, but beware that it may change.)
Dr. Kieran Harty, VMware’s former executive vice president of engineering, is now tackling storage performance and management headaches.
His startup, Tintri, launched in March, after two and a half years in stealth mode, and it received $18 million in series C venture capital funding this month. The company’s product, VMstore, is a combination of hardware and software that aims to solve the problems of storage I/O performance bottlenecks and management complexity in virtual infrastructures.
VMstore is a 4U box that comes with 8.5 TB of usable capacity, comprised of a combination of solid-state Flash disks and SATA capacity. It uses inline data deduplication to compress virtual machine (VM) data so that up to 13 logical TB can fit into one unit. With compression and deduplication — as well as the ability to automatically move data to the Flash disks in small 8KB blocks, according to application demand — the appliance can store between 100 and 200 VMs per node, including high-performance databases, Tintri says.
EMC and VMware are as close as two vendors can get, but that doesn’t make them immune to integration problems.
An issue with some versions of EMC’s Engenuity Symmetrix VMax disk array microcode and VMware vSphere’s vStorage APIs for Array Integration (VAAI) has EMC warning users of potential hits to performance and data integrity.
An unspecified but relatively small number of users have experienced performance slowdowns as a result of using EMC’s VMax arrays at certain microcode levels with VAAI, according to a blog post written yesterday by Chad Sakac, EMC’s vice president for the VMware Technical Alliance.
Microsoft released a second beta of System Center Virtual Machine Manager (SCVMM) 2012 to a broader audience May 26, bringing the product another step closer to general availability.
Due out in the second half of 2011, SCVMM 2012 may bring greater feature parity with VMware’s vCloud Director. New features include new administrative roles and workflows for self-service portals, which are meant to support Infrastructure as a Service (IaaS), plus automated, wizard-driven provisioning of virtual machine (VM), network and storage hardware through Virtual Machine Manager.
