Centralized management of VDI vs. physical computers saves on time and resources however depending on which kind of VDI deployment you have you could be realizing even more savings. Ideally the most efficient deployment type is Non-persistent / Stateless VDI, this is when you have one or many golden master VM’s that are then shared by a VDI pool. When your VM’s are Non-persistent / Stateless the user gets a fresh VM at login and at logout the VM gets recycled.
In a Non-persistent / Stateless VMware Horizon View deployment with Composer the admin creates a base image and performs a VM snapshot that is used as the starting point for the VM’s. When patch Tuesday rolls around and the admin will boot the golden master apply the patch and take a snapshot, the admin then needs to perform a recompose that will update all existing VM’s, and depending on the urgency of the update you might need to have users log off. This process will can take 1 or more minutes per VM.
Is there a better way?
I’ve been doing some updates to Chapter 23 of the eucbook – which I released with my co-author, Barry Coombs last year. The updates are ones that are centered around Chapter 13 which concerns the use of VMware’s vShield End-point solution. In case you don’t know this uses a management appliance (vShield Manager) together with 3rd party vendor (in my case Bitdefender) to offload the payload of AV protection away from your virtual desktops. Bitdefender has recently restructured their offering into what is called “GravityZone” which allows for protection of not just virtuals but physicals from their Control Center – interestingly it also supports the protection of mobile devices too.
Bitdefender GravityZone is the first security management solution to properly address the scalability and performance challenges that enterprises are facing today. Built from the ground up for heterogeneous environments, and using a unique design approach, GravityZone unifies control for virtualized, physical, and mobile endpoints. Organizations have the flexibility to deploy any or all of the three security services within GravityZone: Security for Virtualized Environments, Security for Endpoints, and Security for Mobile Devices.
Optimizing security management for the realities of cloud computing, virtualization, or BYOD is possible through innovation. The GravityZone approach provides organizations with a range of benefits including improved operations, simplified security workflows, increased performance, and reduced administrative efforts and costs. These are achieved through:
- Accelerated deployment by simply importing a virtual appliance
- Massive scalability – from the smallest to the largest installation, without performance issues
- Integration with Microsoft Active Directory, VMware vCenter, and Citrix XenServer for simplified deployment of physical and virtual endpoints
- Unified administration that eliminates point solutions and reduces administrative efforts
I figured there were enough changes to warrant spending my weekends updating the content.
Anyway, I’m free say that this chapter is now FREE to download (so no need to purchase the book). In conjunction with this promotion, Bitdefender have very kindly offered an extended 3-month evaluation for those in the community who want a chance to kick the tires of Endpoint – remember its now part and parcel of the vSphere release. I have 50 of these promotions available – and the first 50 qualify for PSO support.
It’s my very great pleasure to announce the general availability of the “Building End-User Solutions with VMware View” book is now available in hard-copy (paperback). To be honest it was a bit of trial getting there in the end, because for the first time I had issues with getting the PDF processed by LULU. I took 4 attempts at submitting our PDF, and each time it got bounced out of their system because of an issue. It took sometime to get to the bottom of the problem – but it turned out it was associated with a problem with both the file size and fonts. Yes, fonts. You’d think any PDF would be printable because its an encapsulated format – unlike say a Word .doc file which needs supporting “font” files to render the document for printing. According to our print the appearance of some Wingding3 Font types was the source of the problem!
Anyway, the whole business was wrapped up just before I left for Palo Alto a couple of weeks ago, and our sample copies of the hard-copy arrived whilst I was at VMworld. It was a bit of disappoint not have a hard-copy at the bookstore at VMworld. With that said it was more of a “physiological” thing. We would have probably only supplied about 50 books which would have raised about $500 for UNICEF. In the grand scheme of things we sell more online than we would at a conference. But it would have been nice to see it up there on the standards amongst my fellow authors!
The next step for us is sorting out a listing on Amazon – that means acquiring a ISBN for the book, and paying a small fee to LULU for handling the process for us. After that there is an opportunity to get the book listed on http://www.safaribooksonline.com/
For now the PDF and hard copy are now available. There’s two URLs.
