In the past, virtualization architects and administrators were told the best way forward is to buy as much fast memory as they could afford as well as standardize on one set of boxes with as many CPUs as they dare use. With vRAM Pool licensing this type of open-ended RAM architecture will change as now I have to consider vRAM pools when I architect new cloud and virtual environments. So let’s look at this from existing virtual environments and then onto new virtual and cloud environments. How much a change will this be to how I architect things today, and how much of a change is there to my existing virtual environments? Is it a better decision to stay at vSphere 4? Or to switch hypervisors entirely?
Ericom AccessNow is the first HTML5 client for Microsoft RDP/VMware View. An HTML5 offers the option of organisations delivering access to services not only from personal devices, or kiosk terminals, but from the growing range of devices that have a browser as their core OS such as the Chromebook. At the moment, this is a freely available resource – I’d recommend a look.
In a press release on June 29, 2011 AppSense announced that its User Virtualization Platform is now a core building block of HP’s new Client Virtualization Reference Architecture. Along with Microsoft, VMware and Citrix, AppSense User Virtualization has been recognized by HP as a crucial technology for a successful architecture that meets the goals for client virtualization.
Security in the cloud and the virtual environment is ‘all about the data’ and not specifically about any other subsystem. It is about the data. As such the data has something it knows (the contents of the data), something it is (its signature), and something it has (its digital rights) and since it has these three elements, the data has all it has identity. However, protecting the data requires us to put things between the data and the real world such as firewalls, and complex role based access controls, as well as methods to replicate the data to other locations in a non-intrusive mechanism. The goal to such replication could be to ensure multiple sites have the same data (such as a hot-site) or to have the data available in another locations in case of disaster.
As a delegate for Tech Field Day 6 in Boston, I was introduced to SRM Replication as well as ZeRTO a third party replication tool. They seem to be as different as night and day but are they? Both work within the vSphere environment to replicate virtual disks regardless of storage type, and apparently hook into the same location within VMware’s API stack. This shows a maturity of VMware’s API stack that until now has been unknown and secret. In this one area, Microsoft Hyper-V is beating VMware vSphere: The availability of well known APIs that are easy for Third Parties to use. I now see a change in VMware’s behavior, can they continue this growth?
Everywhere you look you hear more and more about cloud computing as well as hearing one of my favorite lines from a Microsoft commercial “Let’s take it to the Cloud…”. Companies are jumping on the cloud bandwagon in quite a big way. I wanted to point out and mention some stories and services that I am using personally and having good success with.
Apple has done quite well serving up the AppStore and iTunes for the mobile devices and Apple has recently announced that it was discontinuing MobileMe and replacing the service with iCloud. It can go without saying that this has been an invaluable tool for use with my iPhone and iPad.
RUM (also called End User Experience Management) is becoming a critical feature of modern APM solutions. This is being driven by the emergence of rich client platforms like Ajax, Adobe Flash, Adobe Flex, and Microsoft Silverlight as well as the emergence of the iPad and Android based tablets as platforms for client side business applications. These applications development trends when combined with virtualization, IT as a Service and Cloud Computing will make RUM into a critical capability for being able to assess how the end user is doing irrespective of what is happening to the deployment model of the back end application.
