Virtual desktop infrastructure (VDI) brings many benefits to desktop management. Virtual desktops are more convenient to manage and scale than physical desktops. For example, you can do the following tasks. \n

Manage virtual desktops centrally \n

VDI brings centralized management to your virtual desktop environment. Administrators can patch, update, and change multiple virtual desktops at the same time. They can also save and back up desktop data for disaster recovery. \n

Scale VDI as needed \n

Since all VDI sits on a central system, you can easily scale it up or down. You can make it more flexible by hosting in the cloud. You can use a cloud service provider to deploy and manage thousands of virtual desktops without having to worry about underlying hardware costs. \n

Increase accessibility \n

You can access virtual desktop environments from anywhere and on any device. This improves user experience because you can bring your own device to the workplace or gain seamless remote access from any location. VDI creates a highly personalized digital workspace, making it more convenient to work from home or remotely. \n

Maintain internal security standards \n

The VDI environment is highly secure because the entire infrastructure is under enterprise control. Sensitive data from multiple virtual desktops sit on a single physical server. You can secure this centrally managed server or host server to meet internal standards. Remote workers can access the data from any device by following suitable authentication processes. The remote machines do not pose a security risk, even if they are lost or stolen. \n

Lower costs  \n

VDI technology brings down IT expenditure because it reduces the hardware costs of purchasing new traditional desktops. It also reduces ongoing management costs because you can maintain virtual desktops by using software processes.","id":"seo-faq-pairs#what-are-the-benefits-of-vdi","customSort":"2"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#vdi","name":"vdi","namespaceId":"seo-faq-pairs#faq-collections","description":"

Virtual desktop infrastructure (VDI) has several use cases across different industries that employ remote workers, contractors, field technicians, and kiosk workers. We give some example use cases below. \n

Call centers \n

Call center employees use VDI solutions to access specific information and tools that they use to complete remote assistance tasks. This helps them streamline efficiency and reduce costs. \n

Remote work \n

Geographically dispersed employees use virtual environments to access the company network, applications, and resources without compromising security. \n

Regulatory compliance \n

Heavily regulated industries use VDI to secure confidential information. Remote data centers store sensitive information, and employees use virtual desktops to access it. This eliminates the problem of incorrect data access. \n

Third-party access \n

Contractors, business associates, and partner services sometimes require access to internal company systems. However, supplying company-owned hardware can be expensive, especially for shorter projects. A VDI environment is an ideal solution that minimizes security risk and gives efficient access to third parties.","id":"seo-faq-pairs#what-is-vdi-used-for","customSort":"3"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#vdi","name":"vdi","namespaceId":"seo-faq-pairs#faq-collections","description":"

vdi","metadata":{}}]}},{"fields":{"faqQuestion":"How does VDI work?","faqAnswer":"

Virtual desktop infrastructure (VDI) has a software layer that abstracts desktop functions, including the operating system functions. Virtualization technology decouples the operating system from the physical desktop. A software application acts as your desktop, on which you can install any operating system and applications. A VDI is a type of remote desktop virtualization because the virtual desktop is remote to the end user. \n

For example, typically, Microsoft Windows desktops are physical machines with Microsoft Windows installed on them. However, virtualized desktops could have a Linux desktop sitting on a Windows server machine. You could access this Linux desktop from your Mac computer without having to install Linux on your machine. \n

A VDI environment consists of two main components: a virtual machine and a connection broker. \n

Virtual machine \n

Virtual machines are the foundation of any desktop virtualization solution. They are machines within machines. A software machine runs on an underlying physical machine or host server. The hypervisor is the software that makes this possible. It partitions the host server into many virtual servers with their own operating systems. These virtual machines use the hypervisor to access the memory, CPU, and other resources of the host server. They create individual virtual desktop environments that end users can connect with remotely. \n

Connection broker \n

The connection broker is the software that facilitates the remote connection between end users and the hypervisor-installed server. When a user connects to the remote desktop services, this software layer authenticates the user and gives them access to their virtual desktop environment. It also facilitates interactions between the remote user and the virtual desktop. For example, the connection broker provides screen updates and sends mouse clicks and keystrokes to the virtual desktop.","id":"seo-faq-pairs#how-does-vdi-work","customSort":"4"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#vdi","name":"vdi","namespaceId":"seo-faq-pairs#faq-collections","description":"

There are two types of virtual desktop infrastructure (VDI) deployment methods: persistent VDI and nonpersistent VDI: \n

Persistent VDI deployment \n

Persistent VDI deployments are remote desktops that are saved for individual end users. Multiple users have persistent desktops that they can customize and reuse repeatedly. \n

Nonpersistent VDI deployment \n

Nonpersistent VDI deployments are single-use desktop instances. The centralized server creates a new generic desktop for every user and then destroys the desktop after use. Nonpersistent desktops are cost effective when organizations have a large workforce using business applications for repetitive administrative tasks. For example, call center employees require a standard set of applications for their work. Any data they create is stored remotely in the business application. You can set up a new nonpersistent VDI for them in every session, and it will not cause them to lose any work.","id":"seo-faq-pairs#types-of-vdi","customSort":"5"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#vdi","name":"vdi","namespaceId":"seo-faq-pairs#faq-collections","description":"

  Two types of VDI services use cloud infrastructure: fully managed and desktop as a service. \n

  Fully managed VDI service \n

  Fully managed VDI service is VDI management software that is available as a cloud-based service for your administrators. The service supports administrators by providing features like existing desktop image templates, built-in security and data encryption, and management of operating system licenses. Administrators perform the deployment, monitoring, application life cycle management, and other tasks to implement the service for your organization. \n

  Desktop as a service \n

  Desktop as a service is a third party that supports the implementation of managed VDI services. They deploy the fully managed service for your organization and also take over administration responsibilities, reducing the need for in-house IT capabilities. For example, Virtusa Desktop-as-a-Service is a scalable and flexible turnkey solution that you can deploy in just three days to allow your entire global organization to immediately begin working remotely. It supplies a full set of services, such as application lifecycle management, endpoint delivery, and ongoing VDI monitoring.

    What is VDI (Virtual Desktop Infrastructure)?

    Virtual desktop infrastructure (VDI) is a software tool to centrally create and manage virtual desktops. Virtual desktops are software applications that mimic real desktop computers. VDI technology creates a virtual desktop on a central server, and remote users can access this desktop from any physical machine over the internet. VDI quickly and efficiently sets up many virtual desktops to provide secure remote access to internal business applications and services. Thus, using VDI, you can cost effectively and flexibly scale up any enterprise desktop infrastructure.
