VDI Personalization and Configuration: Profile Management & Logon Scripts – not enough for multiple delivery mechanisms & OS platforms?

July 24, 2009

As a leading user environment management vendor, AppSense are in a unique position in that we have been involved many VDI projects and rollouts, of which the majority vary in architecture, technology and requirements.  One thing that does however remain the same between such projects is that of the requirement for user personalization management.

For many years the roaming profile provided user personalization in SBC environments, however as VDI deployments become more and more complex, with varying methods of desktop and applications delivery, along with multiple desktop operating systems and subsequently, profile versions, the roaming profile is no longer able to provide the user with their required settings in such (complex?) scenarios.

Furthermore, these desktops must now be constructed and configured based on the context of the user and/or connecting device.  i.e. mapping specific printers local to the user and device dependent on the location of the user logging on, or applying security policies to hide or remove access to network drives, folders, data and functionality such as copy and paste or print, again, based on the location of the user.  Whereby the desktop delivered to a user when connected locally inside the corporate LAN is different to that of the desktop delivered to the same user when connecting remotely from outside of the LAN.

One more point to consider is that of enabling the user to freely roam between the server hosted or provisioned virtual desktop, and the users local desktop device such as their PC or roaming laptop.  How do you as IT enable user settings to automically follow the user between different platforms?

AppSense Environment Manager was designed from the ground-up with functionality to accommodate the above requirements, making it, or, other user environment management solutions essential to the mass adoption of VDI on an enterprise scale.  In essence, AppSense provides the ability to encompass multiple delivery technologies and OS platforms by allowing the user to roam between the paradigms without any noticeable change to their desktop or user experience, enabling IT and the organization to benefit from flexibility, agility and lower TCO.  I do at this point want to highlight that this is different to the personalization management provided by the leading VDI vendors (Citrix, Microsoft, VMware etc), as their in-built functionality is typically designed for their delivery platform, not each other’s.   In essence, further to the advanced personalization and simplification of desktop management, AppSense also enables an organization to use combinations of both existing technologies, and (potentially) more importantly, any future VDI delivery technologies and vendors.
 
I have just found a very nice blog covering the functionality of not only AppSense Environment Manager, but also the base technology inherent within the leading VDI service providers – Citrix, VMware and Microsoft.  Hopefully from this blog post, and the information over at GenerationV, you will see how AppSense bridges the gap between the roaming user and a dynamic, flexible VDI model..

Fair-Sharing CPU usage on Citrix XenApp to ensure Quality of Service and Faster Response Times (With AppSense Performance Manager)

July 23, 2009

The Server Based Computing (SBC) such as Microsoft Terminal Server and Citrix XenApp model offers many unique challenges for both architects and administrators. There are concerns of security, availability of resources, performance and the costs of hardware, licensing and ongoing management. Due primarily to opportunities for cost reduction in hardware purchases however, server consolidation through ‘optimizing performance’ has been the main area addressed. Fewer servers also result in lower licensing costs, lower maintenance overhead, and reduced electricity and cooling costs. However, it has now become apparent the real issue with performance is not just financial, but one of user experience. There is an ongoing tradeoff betweenensuring users receive a consistent ‘end-user experience’ while maintaining the minimum amount of hardware. 

 

Before considering CPU usage, management and optimization, it is first necessary to clarify CPU usage. When a figure such as 60% CPU usage is quoted, what is actually meant is the CPU is being utilized at 100% for 60% of the time. This shows a high CPU value is actually an efficient use of resource, rather than a problem.

 

A CPU utilization of 100%, while considered a problem by many, actually means maximum use is being made of this resource, and therefore achieving maximum return on investment. Problems occur when requests exceed 100% CPU utilization, whereby resource contention and bottlenecks are formed – although, this can be solved by efficiently allocating the resource between the users and running applications.

AppSense Performance Manager is able to control CPU usage in many ways, and may be used to not only resolve CPU usage issues, but also to ensure CPU resource to mission critical applications and users.  In this post I want to cover one specific feature function within AppSense Performance Manager – Smart Scheduling, or sometimes known as CPU Fair Sharing.

Smart Scheduling
With Microsoft operating systems, during process initialization, a priority is assigned for the process to run under. Microsoft Windows 2003 has the following priorities:-
Realtime, High, Above Normal, Normal, Below Normal, Low.

A process which has a higher priority will be allocated CPU prior to a process with a lower priority. Most applications when launched are given a ‘normal’ priority. This means that these processes form a ‘queue’ for the CPU and will receive CPU time only when it is their turn. There are a few standard system processes which are assigned a higher priority, such as the ‘Windows Task Manager’ which is automatically assigned a ‘high’ priority. This ensures should the Task Manager process require CPU time it will be given it immediately.

A process may consume a maximum amount of CPU time, known as the quantum time. If the process does not require the full quantum time, for example if it requires further data, it is able to release the process prior to completion of the quantum time, thereby allowing another process access to CPU resource.

When an application Launches, there are many calls to the disk to access new data, and therefore the process consumes small parts of the quantum time. Processes which involve a large number of calculations, such as highly mathematical applications, tend to use all of the CPU quantum time and are therefore CPU intensive.  If the timeline of processes within the CPU are mapped out the problems become immediately apparent.

For example – Below, Process A is Microsoft Word launching; Process B is a resource intensive Microsoft Excel macro.

 

Blog1

Scenario 1:- Only Process A is running in this scenario, the application performs at full speed as it gets CPU resource when required and disk resource when required.

Blog2

Scenario 2:- Process A and Process B running. In this scenario it is evident that process A has been dramatically slowed down as there is a length of time where it is waiting for process B to relinquish the CPU. This can have dramatic effects on the responsiveness of the process, and obviously increases the time to wait. As process A and B both have equal priorities one process has to wait for the other to finish.

AppSense Performance Manager includes ‘smart scheduling’ technology that is able to share the CPU resource more efficiently between running applications. The priorities of the process are altered dynamically. The result being that processes requiring a small amount of CPU time tend to be given a higher priority than those which tend to monopolize the CPU.

Blog3

In this way the CPU time is divided equally amongst both processes ensuring that each has a share and no one process is hogging the CPU, causing others to wait. Process B receives much smaller chunks of CPU time but similarly its waiting time is also short, ensuring that the application appears responsive to the user, and therefore still falls within its time to wait. The effect of this process is greatly reduces the CPU queue length.

By interpolating between standard priorities, and dynamically adjusting the priority of each process, AppSense Performance Manager is able to ensure more efficient processor usage. More importantly, from a user perspective, no application is seen to “freeze”, ensuring application responsiveness falls within the acceptable ‘time to wait’ period.

Share Factors
In the above examples we assumed both process A and B are equally important and therefore require an equal use of resources. In most cases this is not a true representation of applications and users. Servers contain both mission critical applications and also users with varying degrees of ‘importance’. By implementing share factors within AppSense Performance Manager, these applications and/or users may be given a higher or lower share of CPU time.

If the process A is a mission critical process then it may be assigned a higher share factor. The effect of this is to raise the priority of the process so that it may have a longer CPU time before process A is given a higher priority.

Blog4

Here process B has been given a higher share factor resulting in process A waiting on process B. The difference now is the time process A has to wait is a value which is configurable by the Administrator. A further function of AppSense Performance Manager is the ability to apply application or system state control. An application may be defined as having a high share factor when in the foreground, a medium share factor when in the background, and a low share factor when minimized.

If we now look at things from a user point of view, the application they are currently working on will always be guaranteed to receive CPU time, and can therefore always be made to function within its required time to wait, hence “performing well”. Other processes continue to receive a share of CPU time ensuring that they also function. One key system state for SBC systems is the ‘disconnected’ state.

By assigning a relatively low priority to all other states we can ensure that users who disconnect from the server without logging out properly, do not continue to consume valuable CPU resource which is then made available to all other users.

In conclusion, Microsoft Windows operating systems go some way to addressing how applications make use of system resources, but it is clear that in situations of high resource usage, such as in SBC environments, they are challenged. AppSense Performance Manager addresses these shortcomings. It provides many methods of controlling critical system resources such as CPU, Memory (both physical and virtual) and Disk. It’s CPU scheduling algorithm ensures that even in times of maximum CPU usage the server remains responsive for each user and application. If necessary, weighting may be given to ensure minimum response times for mission critical applications and/ or users.
