When layers become a problem

I have seen a lot of discussion on the subject of layering of software images to deliver virtualized client computing. There are some interesting opportunities here but also a number of serious potential issues. This is too big an area for a single blog post so I am going to look at this over a number of post in the coming weeks.

There are number of different ways the word ‘layers’ is used in client computing. Firstly, when we think of our software stack we unsurprisingly think of the layers that make up that stack. Those layers are typically operating system, applications and user environment. We then think about how we manage those layers, either as the complete unwieldy stack or individually. As  such we are thinking about layers as a handy shortcut for what we want to manage individually.

Another way that the word ‘layers’ is being used is as a way of splitting the stack into a large number of separate layers. A number of small vendors are launching early stage products to try and deliver solutions based on a layer per application with those layers being delivered selectively depending on the user. The problem here is that each of the layers then needs to be managed separately including the impact of every combination of layers. Many of the organizations I talk to have thousands of applications in use across the business, that means thousands of layers and a huge combinatorial problem.

The change between the two uses of the word ‘layers’ is dramatic: In one case we are referring to three layers that we want to manage individually in the other case attempting to manage thousands of layers in a way that may well prove to be impossible. As I think of managing all those layers I am reminded of the mess that usually results from my attempts at eating a Napoleon, also known to the French as a ‘Mille Feuille’ – thousand layers.

Virtualization Executive Summit Event Review

Last week I attended the Virtualization Executive Summit, a great event attended by almost 100 Senior IT Executives (CTO’s, CIO’s, CEO’s, VP’s, Director’s etc..) from very large, international organizations. As the name suggests, the event focused on Virtualization, with a large proportion of the end user interest being in Desktop Virtualization.

I have to say, it was a very well organized and thought-out event, with each of the delegates having individual time tables based on their areas of interest. These time tables accommodated both vendor boardroom presentation sessions along with 1:1 meetings with the vendors too, so a busy two days for all involved.

As part of our sponsorship package, I was presenting in the AppSense Boardroom Session. It appeared to be very well received (with some of the attendees saying it was the best session they had been to <- queue big ego boost for me lol). There was a great mix of people in the room, some who had deployed Desktop Virtualization and some that had also done stateless / non-persistent Desktop Virtualization with a user environment management solution (like AppSense ;-) ) which was a great validation for the others in the room who are still in their planning stages.

Nearly all of the many meetings we hosted focused on the attendee’s plans for desktop virtualization in 2010, and I am glad to say, they were also asking how AppSense could help enable them to adopt the non-persistent virtual desktop model.

Thanks to all of those who helped make this a great event, and thank you also to all those who attended and are driving forward with desktop virtualization..

Looking forward to the next one :)

Centralis use Citrix XenDesktop & AppSense for 3,000 users at Dudley PCT

Dudley Primary Care Trust (PCT) has worked with Centralis (a key Citrix & AppSense partner) to deliver a virtual desktop environment to over 3,000 staff.

Using Citrix XenServer, Citrix XenDesktop, Citrix XenApp and AppSense, Dudley PCT are able to provision desktops to their staff from just 16 Virtual Servers.

AppSense enables a single standardize image of the OS and Applications to be stored, managed and delivered as fully configured and personalized desktops to thousands of users at minimal operational cost.

The VDI Penny Is Starting to drop.

Enviroman (Oliver Sills, Product Manager for AppSense Environment Manager) was in the office the other day, pestering me about signing a petition to change the Environment Manager “colour” from green to Tangerine – something to do with some UK footy club. I told him the Budgie Smugglers don’t look any better in Tangerine, so stop sitting on my desk :-)

Just about then the phone rings, it was a Solution Architect from a large software company. “Tell him about Personalization”, Environman whispers in my ear. I covered the phone, told him to go way, and went back to the call.

Turns out one of his clients was trying to deploy 600+ Virtual Desktops, and it had just dawned on them that Policy, Profiles and the User Personality had become a nightmare to maintain when using a Non Persistent Pooled Desktop environment.

Think about it – each user, every time they log in, has a brand new base model PC.

This Client did a Proof of Concept – easy – P To V a couple of desktops, load a client, connect in using RDP – jobs a good’un – look Mum no hands – I’m doing VDI :-)

So then they ticked all the boxes, app compatibility – tick, ease of use – tick, centrally managed and deployed – tick, user acceptance – tick, user personalization – tick – hey, not so fast.

You CAN have a tick in that box if you are talking One to One, dedicated hosted virtual desktops for a small number of users – otherwise, you need to think again.

It’s like when I started talking to the Aussie market about AppSense back in 2004 “Yes I hear what you say, but I’ve only got 5 servers – it’s not a problem” 6 months later “Yes I hear what you say, but I’ve only got 10 servers – it’s not a problem” 6 months later “Our farm is out of control, now we have 15 Citrix servers we now understand what you guys were on about 6 months ago”

As we always say – we don’t hold a grudge – and we don’t ever say “I told you so”.  After all we’re from AppSense – we’re here to help :-)

Virtual Desktops are starting to ramp up, and unfortunately with some clients projects, the devil will be in the detail.

Like the client we are now helping, they thought the “Profile Stuff” built into the VDI solution would be the easy bit. “There’re tools built into the base product” they say – yes there are, but those built in tools can be compared to other in-built free software like NTBackup – yes it will backup a file, but it’s not granular enough, and it just won’t cut it in an Enterprise environment – that’s why companies invest in a Third Party backup products.

AppSense is exactly the same. Built in “Profile” tools or features are o.k. for a simple small deployment where one size fits all, but the reality is most organisations will need more.  The reason for this is simple, profile management tools are there to solve profile issues such as bloat and logon times.. they are not designed to be cross platform, cross delivery mechanism personalization solutions, not to mention the need for policy action control also.

It’s just not as easy as saying “We use Roaming Profiles and redirected folders” – try reimaging every PC in your business, every morning, and see if it causes a few hassles for users.

So we keep plugging away out there – educating the market in advance, some clients “get it” up front and they’re the ones with the smooth running, no surprises VDI projects.

As for the rest of you – we’ll be here, happy to answer questions, happy to show and tell – all with passion and enthusiasm.

After all – we’re from AppSense – we’re here to help :-)

• User Environment Management Overview
• Windows 7 and VDI Overview
• Eliminating the need for Roaming Profiles
• Rolling-back User Personalization Settings
• Automatically Blocking Unauthorized Executables

Migrating User Profiles And Existing Personalization Settings to Win 7 with AppSense

A major challenge in migrating existing users to Windows 7 is user profile data and desktop setup scripts. It’s highly unlikely that anything the user has done to their existing machine to personalize it will be compatible with the new Windows 7 desktop. The result? All upgraded employees have to re-personalize their desktop – not a quick task, especially as the process to make such personalization changes may require changing options and settings in new menu locations.

One of the most important things to consider in your Windows 7 migration project is the retention of all user-specific information (we call it the “user personality”) from the ‘old’ desktop and simply injecting this back into the new Windows 7 desktop following upgrade, ensuring a seamless experience to the user and a de-risked Win 7 migration. 

AppSense Environment Manager has been providing user profile migration solutions for global companies for several years, and fast becoming an essential component in many Win 7 migration projects.  AppSense automatically identify all existing personalization settings on the current OS platform, separate them from the desktop and store them independent of the desktop itself.  These settings can now be re-applied to the new Win7 OS platform, regardless of how the OS is hosted or delivered, either physical, virtual or provisioned..
