Best VDI Deployment Models and Best Practices

For better security of data, saving cost, giving remote access to the employees, and managing everything centrally, companies are adopting VDI deployment models. VDI stands for Virtual Desktop Infrastructure. It allows companies to have all their data in a cloud server and employees can use thin clients to log in to their remote desktop and do their job. Organizations with bring your own device (BYOD) programs can also reap the benefits of VDI deployment. In this article, we will have a detailed look at what VDI is, different VDI deployment models, and best practices. So, without any further ado, let’s get to it.

What is Virtual Desktop Infrastructure or VDI?

Virtual desktop infrastructure aka VDI is a technology that allows end-users to use virtual desktops from a different device. That means, if your company has done VDI deployment, you will be able to assign virtual desktops to your employees. These virtual desktops will be hosted in your centralized server and users can remotely access their virtual desktop from a different device which can be their own computer (if your company has a ‘bring your own device’ program) or thin clients provided by you.

Benefits of VDI Deployment

There are multiple benefits for your company when you have done VDI deployment. Not all organizations need to deploy VDI, but those who need, can reap these benefits from VDI:

1. Give your employees remote access to their virtual desktops

As the desktop is virtual, your employees can use any device with an internet connection to connect with their virtual desktops assigned by you and do their job remotely. Employees can use their own laptop or thin clients with low specs to log in to their virtual desktop and still perform tasks that require a powerful computer.

Graphic-intensive tasks like 3D rendering and modeling can gobble up a lot of processing power. If you want to give your employees the ability to work remotely from different locations without having to carry a powerful device, do VDI deployment and assign a powerful virtual desktop that your employees can access with any device remotely and still do the heavy processing.

2. Save a lot of money

Generally when you provide physical desktops to your employees, if you have a lot of employees working for your organization, you have to make a huge investment in purchasing all those physical machines. And some of your employees will require a desktop with higher specifications to do processing-heavy tasks. On the other hand, a normal low-spec PC will be more than enough for employees who just need an internet connection to perform day-to-day tasks which don’t demand a lot of processing power.

By doing VDI deployment, you can save a lot of money by reducing the cost of purchasing different types of physical machines for your employees. VDI will let you do all the processing on a centralized server. And your employees will be able to perform all their tasks from any device regardless of how low-spec the end devices are. This will reduce the cost of purchasing expensive hardware to make workstations for your employees.

3. Top-Notch Security

As all the data is stored and processing is done on a centralized server, there is no fear of employees losing their devices. Whatever happens with the end devices, your data will be safely stored on the centralized server.

4. Manage Centrally

As all the virtual desktops lie on a centralized server, it becomes easy to patch outdated software, change the configuration or update anything else on the system for the IT team. Everything can be managed from one single place.

Different Desktop Virtualization Deployment Models

There are 3 types of desktop virtualization deployment models available:

1. Virtual Desktop Infrastructure or VDI

VDI allows you to run the Operating System on a virtual machine that is hosted on a server. You can then provide the OS and application remotely to the virtual desktops of your employees. You will be able to allocate the resources like processing power, memory, drivers, etc. to each of the virtual desktops with the help of a hypervisor, depending on the tasks that will be performed on them.

2. Remote Desktop Services or RDS

RDS gives remote access to desktops and Windows applications to the users that are stacked on top of Windows Server OS. RDS gives us the ability to support multiple users with a single Windows Server instance. The server resources are distributed among all the users.

3. Desktop-as-a-Service or DaaS

When using DaaS, all the virtual desktops are served from a cloud infrastructure that is scalable. You can easily scale the resources that you need. The infrastructure is maintained by the cloud provider itself so that you can focus only on growing your business. But customization is a bit difficult to do with DaaS.

VDI Deployment Best Practices

Following best practices can make VDI deployment successful. Here are a few of them:

Consider End-User Requirements

Before deploying VDI, you need to properly list down the requirements for the end-users. Consider the total number of end-users, types of most used applications, need for special hardware, user profile persistency, required peripherals, authentication, monitor support, etc. before planning the VDI deployment.

Availability of VDI

Keep a close eye on the availability of hosts in a VDI cluster, redundant storage, power, and networking before planning the VDI. If any of these aspects isn’t handled properly, the availability of the VDI may suffer, cause an interruption in service and financial loss.

Thin Clients and Security

Invigilate the VDI system to make sure no unwanted or malicious software is installed on the virtual desktops by the end-users. If users have the ability to install software on their virtual desktops, they can unknowingly install malware. A non-persistent VDI configuration can be used to restore the settings to safe defaults once users log out. This will deprive the ability to install software by the end-users reducing the security vulnerabilities.

Control BYOD

You can make a list of device types that will be allowed to connect to the VDI. This will help you manage the device type support for VDI. Keep a close eye on which devices are accessing the VDI to prevent any breach.

Conclusion

We hope you have a good idea about the VDI deployment models and best practices by this time. Not every organization needs VDI, but for those who do, it can give significantly great results, save a lot of costs and provide better security of data and remote access to the end-users.
