VMware or Microsoft – A Look at VDI Supportability and More

A little ‘history before. Virtual Desktop computing has its way slowly clouding over that expected in the previous year . The benefits can be enormous if isolating the end user in a virtual desktop that looks and behaves like the PC everyday regularly. Of course, the return on investment has been very difficult to manage, especially when considering large deployments , and when performance must be guaranteed to meet or exceed the current computational requirements .

VMware VDI jumped into the ring for many years , mainly through a number of acquisitions , and in the early years has struggled to gain momentum against Citrix . After all Citrix owns this market for many years , almost single-handedly . Citrix has a piece of client connectivity so finely tuned that it was very difficult for other suppliers to compete in the space . The answer to this was the VMware license the Teradici PCoIP protocol . And so, in recent years , VMware has continued to take some market share in the face of Citrix VDI . Which brings us to the present.

Enter Microsoft Server 2012 study material  Remote Desktop Services (RDS ) . Most of us think of RDS simply as the traditional method of calculating the terminal server in which one part of the server installation on many desktop or application sessions for end users . The majority of companies are still using this traditional type of presentation of the application , as most of them offer virtual desktop. The reason ? ROI is much easier to show for terminal sessions than it is for individual virtual machines. An important note to make here , Microsoft has provided the operating system of the server to make this method can be trivial from the beginning. So when you hit the road Server 2012 , Microsoft certification training has delivered an offer for not much more complete than encourage those pieces that have performed so well , but also to bring Virtual Desktop Infrastructure (VDI ) computing to the next level in terms of fulfilling performance , ease of use , and last but not least, cost. From the connectivity protocol client (PSR) for the ability to deploy virtual desktops or traditional terminal services through a simple wizard integrated into Server Manager recently re-imagined , Server 2012 now plays a much more simple in the VDI space .

Architecture, Complexity, and Support


VMware requires different Windows servers in order to complete its offer VDI . On these servers , the administrator distributes the agent ( controller) , client connectivity and gateway , manager virtual machine image (composer ) of , and vCenter , while providing back-end infrastructure to accommodate these machines ESX virtual . Given a large deployment of VMware View? Think vCenter separate case because there are only so many allowed to vCenter virtual machines . So a manager must understand VMware View vSphere management , Windows Server management , networking, storage services desktop background images , desktop applications , and the list goes on .

When an engineer who proposes to implement a virtual desktop infrastructure should be the top priority should always be in your mind how I can make the desktop experience for the end user transparent , fast , responsive , flexible and , above all , clear . However, in the solution of VMware infrastructure architecture requires a great deal ‘ of time and training before any of these critical issues are addressed. That software can be installed easily , but how I can offer data deduplication, user profiles and virtualized applications ? Other applications are required , plug- ins for storage vendors and the like. Then the administrator must protect the gateway , the bandwidth management of the network, the use of CPU and memory monitor, end-user perception and the like. This sounds like a group of people do not ? The whole project can be exasperating to maintain control , let alone continue to adequately support over a period of time. Consider this, all the servers and the application described above requires changes as operating systems and hypervisors .

There are 22 points of contact and, in this diagram represents only a basic configuration of a single point of failure. When the hypervisor is updated, so does the Virtual Center, which in turn launches new VMware tools (agents) for each virtual machine. In the White Paper can be seen here, touts VMware customers need direct support from a single source, and I could not agree more. The question of the talks White Paper on providing support for desktops are not from Microsoft Certification Practice Tests , and although there are some customers who use Linux here and there, most virtual desktop work is done in Windows. So if you look at the chart above you can get an idea of the complexity of the model of support that come into play. Now check out the new wave of VDI technology:


Microsoft online training has built architectural deployment for each component of the solution RDS, as well as monitoring, ease of use and remote client connectivity directly to the assistant for VDI implementation. For example, instead of learning other software applications, in order to implement a given solution, Server Manager now provides a wizard driven system easy to deploy virtual computing environment for a given scenario. Administrators can implement an aggregate collection desktop, desktop computers, personal, and traditional terminal server, all from the same interface. The wizard will also help guide the technician through the entire process. As seen here in 13 shots or so, you can easily implement a VDI environment, and that’s before Server 2012 R2:

Storage, Linked Clones, Deduplication

VMware linked clones used to provide more desktop based gold a given image . Although this cloning technology really helped bridge the gap of storage utilization , VMware also uses other storage technologies from vSphere to further beautify your offer. Again, we have to be more of a software package. What storage provider is using the administrator ? They support various storage upgrades or plug -in? Imagine that users have become accustomed to their virtual desktops and a new image with the changes implemented then something goes wrong in the procurement process . Where to begin to solve the performance problems ? In the controller, the disk subsystem , or something in between ?

Insert the Windows Server 2012 R2 builds on the vision 2008R2/2012 Server and really , it dissociates from the competition. Virtual desktops can now have their underlying virtual disks placed on different storage tiers . In fact , the desktop for some users or groups of applications can be configured to use physical drives SSD , while under working loads slower SATA sit on the shelves. In addition, Server 2012 RDS also enable hot data cache to speed to get to these bits and bytes is even more incredibly fast . Some people may think this requires some special scripting or PowerShell , but it really is as easy as a few clicks in the Server Manager. Because deduplication technology introduced Server 2012 , Microsoft CBT the RDS team , ” Hey why not to VDI ? ” And now in 2012 R2 , deduplication VDI machines in real time is a reality. In my tests no loss of performance may be , in some cases , machines have quickly responded deduplicated unit due to caching technology dedup !

Now you may be wondering , “Okay what the entire file on the disk is written only happens once or block-level deduplication ? ” Well, the answer is no. The dedup really happens to a piece level . And pieces of data that match pointers are eliminated simply classified in the first data set that fit. This process is performed on a program and is configurable by the administrator. Server 2012 does not matter what type of memory you can use below the virtual machine. So let’s return to the stage offered at the controller level . I common desktop or desktop personal ? Of course , we should not rely on the complexity of the Linked Clone technology , at this point. Regardless of the type of execution ( shared or personal ), RDS can create multiple virtual machines and to give each of the different individuals , minimize duplication in the storage space up to 90% .

An important aspect that should not be left out, the windows operating system physical or virtual . Since Microsoft classes provides the operating system and integrates drivers for the ‘ hypervisor Hyper – V provided ” hardware”, without the need for special agents . This unique ability redefines the ‘ user experience in several ways. For example, connectivity protocols and interaction with these protocols desktop level . Streaming Charts RemoteFX has fallen by 50% in the release of Server 2012. To put this in perspective, RemoteFX Server 2012 and it was noticeably faster than 2008R2 . Another example , let’s say the desktop is displayed in portrait mode and end-user tablet is in landscape mode. Windows Server 2012R2 8.1 and automatically determine the occurrence of a change of perspective , redraw the screen in the right format , at the time . No special software or client required agents.

Say that again. “No special client software or agents needed.” He should have made ​​the title of this article .

With regard to the management of the original images , if an administrator uses System Center Configuration Manager that can serve your master images as good VDI environment and its physical equipment . The answer to this is another VMware to install software called Mirage , here we go again, another tool to learn , maintain, etc. When you circle back to the beginning of this conversation and discuss virtual desktop virtual desktop delivered by Windows original Terminal Server sessions , but it is even more beautiful on Server 2012 , I think we can close the loop of what should be considered the true all – in-one virtual desktop solution . The bottom line is that VMware has to begin consolidating all your software purchases in a hurry if they want to play seriously at this stage .
