Is Windows 2012 Remote Desktop Session Host better than Citrix XenApp?

PresentationVirtualizationIs Windows 2012 Remote Desktop Session Host (RDSH) better than Citrix XenApp? Citrix XenApp 6.5 is a market-leading product. Citrix XenApp may well be the first product businesses consider when deploying applications or desktops from a centralised service. Windows 2012 is very new. Windows 2012 RDSH, as a new service, doesn’t have the same number of partners or administrators with detailed experience.

Still, it’s a very good question.

It’s a very good question because Microsoft has worked hard to ensure that RDSH is a solution viable not only for large enterprises, but small and medium scale businesses and not-for-profit organizations, as well. Windows 2012 RDSH builds on a mature technology, a technology that is the most-deployed centralized desktop virtualization solution.

Yet, are you going to end up reading this article and get to an “it depends” answer?  Let’s see.

Microsoft Hyper-V vs VMware vSphere

DataCenterVirtualizationOne topic that gets discussed quite often is Microsoft Hyper-V vs VMware vSphere, and a quick Google search for comparisons will return at least several hundred thousand hits. There seems to be a large number of posts and articles trying to make a case that one is better than the other by listing and comparing features of the hypervisors themselves one by one. The purpose of this post is not to claim that one platform is better than the other. Is that the best way to really compare the different virtualization technologies as a whole, or should we take a step back and really look at differences in approach for the virtual infrastructure and/or virtual ecosystems?

Gaining Visibility into The Cloud: Migration and Security

IaaSSecOn many a Virtualization Security Podcast I tend to mention that we need greater visibility into the cloud to judge whether Cloud Service Provider security measures are good enough. But why should we bother?  I am not saying we should not be concerned about a cloud’s security but that we should as tenants be concerned with clouds meeting our security, compliance, and data protection policies and requirements. Will a cloud service provider ever be able to meet a specific organizations requirements as well as the cloud service providers policies and compliance?

Cisco Nexus 1000v: Free unless you want Security

VirtualizationSecurityWhile not particularly new news, the next version of the Cisco Nexus 1000v will be free, unless you want the security features. This is an interesting shift from Cisco with respect to VMware vCloud Director, the Nicira purchase, furthering UCS, and Cisco within non-UCS data centers. However, given other announcements, with respect to OpenStack, perhaps this is more a play to level the playing field between cloud architectures? But what I find most interesting, is that the changes to the Nexus 1000v also align with the changes we see in the vCloud Suites from VMware. Continue reading Cisco Nexus 1000v: Free unless you want Security

Quest vWorkspace Returns

DesktopVirtualizationOh dear. Did I get it wrong. Three weeks ago I asked “What does the future hold for Quest vWorkspace?“, where I described vWorkspace (at that time unaccountably renamed Quest Workspace Desktop Virtualization) as being “no more than an unwelcome distraction” and suggested that the best thing for Dell to do, at least as far as the product was concerned, would be to sell it off to VMware or Teradici. Well, it looks like Dell can’t have taken my suggestion seriously, because this week vWorkspace is back! Continue reading Quest vWorkspace Returns

How Will VMware’s Distributed Storage Change their Relationships?

DataCenterVirtualizationAt VMworld 2012, VMware presented a Tech Preview of one of their latest ideas, which they termed “Distributed Storage”. So what exactly is this new technology? It is basically locally attached storage.

How is Distributed Storage new?

We know that VMware has allowed the use of local storage since inception; however, access to that storage was limited to the local host only, so it was only utilised for guests that were node-based, e.g., vShield appliances. To delve a little deeper you could use the analogy of a VSA (Virtual Storage Appliance), but unlike the VSA, which is a fully functioning virtual machine, this technology is actually part of the hypervisor.
