Administrative – organizational virtualization solutions

This category of solutions is suitable for most administrative and organizational groups such as: insurances, municipalities, private companies, etc.

The first solution: VDI _ PCoIP, ICA & HDX

This solution is suitable for companies that have a virtual server platform or do not have any problems with its deployment.
In other words, this solution will not be economically justified for companies of less than 30 users, because the following items are required. (But it has special and inevitable attractive features that we will examine below):

  1. At least one server (or several servers to fully launch the features) to launch the virtual platform
  2. On the user side, we need PC or thin client or zero VDI client, which is the most optimal use of VDI zero clients.
  3. Knowledge of server and desktop virtualization required for setup and support

In general, there are four operation methods in this protocol:

  1. Each virtual machine can only be assigned to one user.
  2. Windows created a server as a remote server and distributed it to users after making the relevant settings (terminal service). (RDSH) in a way to give desktop session to users from the same machine.
  3. For the system, we introduce a template with all the programs we want to be on it.
    And this is the system that intelligently provides a copy of that template to every user who enters.
  4. We only provide the necessary programs to each user in a specific environment and do not provide the desktop environment to users (click for more details in the topic of virtualization).

Pay attention to the following figure (related to PCoIP):

PCOIP

The two protocols PCOIP and ICA/HDX are both interpretations of the VDI solution and have similar overall functionality. (4 above-mentioned methods), but each one has its own advantages and characteristics, which are in line with the policies of the two prominent companies, VMWARE and CITRIX. These two companies are among the pioneers in the field of virtualization (server and desktop) and we will discuss a comparison between these two protocols in the form of questions and answers.

Advantages of using this solution:

  • Easy management
  • Very high stability
  • Reduce maintenance and support costs
  • Centralized management from one place (ease of service from the headquarters to the queue)
  • Using low-cost Zero Client devices
  • No software dependency (Microsoft, Apple, Android)
  • Easy to upgrade software and hardware and low bandwidth consumption (suitable for use in WAN)

Disadvantages:

These products belong to the most prominent companies in the field of virtualization. And there is no technical fault, and if it is seen, it will be fixed in software updates.
Therefore, the disadvantages of this solution are those that are not optimal or cost-effective compared to other solutions, which we mention below:

This solution is perfect for administrative and organizational companies!

To answer this question, we examine the main policies of the two companies providing these products:

VMWARE: The products of this company (VMWARE) have been produced with the policy of maximally simplifying the use of virtualization for the use of a wide range of audiences and have the following features:

  • Ease of setup
  • Integrity in management
  • High stability
  • Avoiding details (compared to other types of virtualization solutions)
  • Up-to-date and progressive
  • High security
  • Being free (this issue will be discussed further in the form of questions and answers)
  • Availability
  • Synchronized and compatible with server hardware

ICA / HDX: These products are provided by Citrix company with the policy of optimal use of resources and bandwidth and providing the highest quality in user experience and with all the details.
which is the best enterprise solution and has the following features:

  • Management integrity
  • Maximum attention to specialized details
  • High flexibility (it has many features that can be changed according to the conditions)
  • High stability
  • The highest graphic experience and efficiency among all types of virtualization solutions
  • The lowest bandwidth usage rate among virtualization solutions

Since the main goal of these two companies is to provide a perfect experience, and having a very large customer community, they quickly fix the problems and bugs that are discovered.
And they are not technically flawed, but for this use case (administrative and organizational solutions in Iran), each one has advantages over the other, which include the following:

  • Compared to VMware, the Citrix solution is more complex in implementation and requires more specialized knowledge.
  • Compared to VMware, Citrix solution requires more and more complex infrastructure.
  • Compared to VMware, the Citrix solution is more efficient in bandwidth consumption.
  • Compared to VMware, Citrix solution has much more customization capabilities.
  • Citrix solution is more expensive compared to VMware (in terms of licensing)
  • Compared to VMware, Citrix solution is more efficient in consuming resources.
  • Compared to VMware, the Citrix solution has much fewer customers in Iran (due to the more specialized and expensive licenses).

This is how it works:

  1. Deployment of server virtualization
  2. Choosing a suitable device for users (PC, mini-PC, thin client or zero client)

The second solution: DDP

This solution is a desktop virtualization solution and is suitable for all administrative and organizational sets!

  • Regardless of the virtualization platform (as long as it is used in the virtualization platform, server virtualization capabilities will be added to it)
  • Regardless of the type of user (even for heavy and professional use, it is one of the best options)

In fact, this protocol (DDP) is an optimized version of Microsoft’s RDP protocol, which is modeled after the H.264 image standard and works as follows:

  1. The differential image is generated by the server.
    (That is, only the differences of the frame with the previous frame are produced, that is, only the pixels that change are streamed, and as a result, it puts much less load on the server)
  2. Images are compressed by a special algorithm. More than 80% less bandwidth consumption compared to RDP
  3. Compressed packets are encrypted by a special algorithm.

In this solution, we provide one or more hosts (operating system) to all or a group of users, which can:

  • Any version of the Windows operating system (XP, 7, 8, 8.1, 10, 2008R2, 2012R2, 2016R2 – 32&64Bit)
  • be physical or virtual.
  • virtual on any platform (VMware, Citrix, …).
  • A template in Horizon.
  • It could be a desktop PC!
DDP

The resources required for this protocol are calculated for both office and professional users and are as follows:

1- Office user:

  • Each user 1.5GB of RAM
  • One CPU core for every 2.5 users (we consider double the number of CPU cores that have hyperthreading).

2- Professional user:

  • Each user 2GB of RAM
  • One CPU core for every 2.5 users (we consider double the number of CPU cores that have hyperthreading).

Keep in mind to reserve 2GB of RAM for the host itself, for example, consider CPU I7 and 24GB of RAM for 20 office users.
The above sources are for the image resolution of 1336×768, which is a suitable resolution for monitors up to 20 inches in size.
It is considered that higher values require more resources and lower resolution values require fewer resources.
The above example is intended for optimal user experience and many customers use the above resources for even 30 Office users.

The type of operating system is also effective in the amount of resources; In terms of optimal use of resources, we rank operating systems as follows:

  1. SERVER 2012 R2
  2. WIN 8.1
  3. WIN 7
  4. WIN 10

Ram bass is very effective in system performance. (DDR4 RAMs should be used if possible)
SSD must be used for the operating system and programs for more than 5 users.
(SSD reading and writing speed is very effective in system performance, the optimal speed is about 500MB for reading and writing, for the number of users more than 30 people, you must use SSD plus RAID0.)

  • Optimum use of hardware resources (better than RDSH)
  • The possibility of using all the advantages of server virtualization (HA, BC, …)
  • Low consumption of network bandwidth (slightly more than Citrix and less)
  • Management and monitoring capabilities of the management panel (explaining the features below)

  • Eliminating the requirement of having a server and providing appropriate server services
  • User quality similar to PC (image quality and efficiency)
  • The most affordable solution available
  • High information security
  • Completely Persian
  • Use without the need to have special knowledge
  • The possibility of playing a desktop for all users
  • The possibility of online and simultaneous desktop monitoring of all users
