Thanks to modern technological innovations, businesses can access a wealth of solutions to boost flexibility, improve security, streamline operations, and manage desktop environments. Desktop virtualization offers a practical approach to achieving these goals. This guide will provide a detailed perspective on how desktop virtualization works and the significant benefits it can bring to your organization.
What is Desktop Virtualization?
Desktop virtualization allows users to create and utilize a simulated workstation environment, granting remote access to a desktop from a connected computing device (such as a laptop, smartphone, or tablet). The virtual version of the desktop environment and operating system exists separately from the original device or client.
How Does Desktop Virtualization Work?
Desktop virtualization can be implemented through several methods, typically categorized based on whether the operating system instance is local or remote:
-
Local Desktop Virtualization: In this model, the operating system runs directly on a client device with the help of hardware virtualization. All processing and workloads occur on the local hardware. This approach is beneficial when users do not need a continuous network connection and can rely on local system resources to meet their application requirements. There are a few limitations since this model cannot share resources or virtual machines (VMs) across a network to mobile devices or thin clients.
-
Remote Desktop Virtualization: This model involves running operating systems and applications on a server within a data center. Users interact with these systems via a client device, such as a laptop, smartphone, or thin client. This setup allows for centralized management of applications and desktops, optimizing hardware usage by providing remote access to shared computing resources. This approach offers greater flexibility and control over the computing environment.
Desktop Virtualization Deployment Models
Choosing the best desktop virtualization solution primarily depends on your organization’s needs. With a few different deployment models available, you can select one that fits your goals for flexibility, scalability, and ease of management.
Virtual Desktop Infrastructure (VDI)
In VDI, the operating system operates within a virtual machine (VM) located on a server in a data center. The desktop interface is transmitted over the network to the end user’s device, allowing them to use the desktop and its applications as if they were running locally. Each user has their own dedicated VM running its own operating system. The resources, including drivers, CPUs, and memory, are managed by a hypervisor, which allows multiple VMs to run side by side on the same server.
Remote Desktop Services (RDS)
Remote Desktop Services (RDS), also known as remote desktop session host (RDSH), allows users to remotely access desktops and applications through a centralized server operating system. Applications and desktop environments are delivered via a remote desktop protocol, enabling multiple users to share a single server instance. This setup makes RDS a cost-effective option compared to VDI, as it supports numerous simultaneous users on a single server; however, it is important to ensure that the applications used are compatible with the server operating system to avoid any functionality issues.
Desktop-as-a-Service (DaaS)
DaaS hosts VMs on a cloud-based backend managed by a third-party provider. DaaS is scalable, flexible, and often deploys faster than on-premise solutions. It shares numerous benefits of cloud computing, such as support for fluctuating workloads, usage-based pricing, and access from any internet-connected device. Depending on your specific goals, DaaS may have certain customization limitations compared to other desktop virtualization options.
How Desktop Virtualization Benefits Your Organization
Desktop virtualization offers numerous advantages that enhance flexibility, security, and efficiency for businesses, such as:
-
Resource Utilization: Centralizing IT resources in a data center improves efficiency by pooling resources. This eliminates the need to push OS and application updates to individual devices. With desktop virtualization, any device—whether it’s a desktop, laptop, tablet, or smartphone—can access virtualized applications. IT departments can deploy less powerful, less expensive client devices since they are primarily just used for input and output.
-
Remote Workforce Enablement: Desktop virtualization facilitates remote work by allowing new user desktops to be provisioned in minutes. IT support can focus on virtualization servers without worrying about the end-user device. Users can access key applications from anywhere with internet connectivity. When a user leaves the organization, their virtual desktop resources are returned to the central pool, ensuring efficient resource management.
-
Enhanced Security: Desktop virtualization provides a high level of security by separating the desktop image from the physical hardware. Centralized security control allows IT to manage hardware security needs on virtualization servers and implement robust identity and access management with role-based permissions. This setup limits users to accessing only the applications and data they are authorized to use. Additionally, since data is not stored on end-user devices, there is no risk of data loss if a device is lost or stolen. The virtual machine delivering the desktop can be a carefully controlled environment managed by an enterprise IT department, significantly reducing the risk of security breaches.
-
Simpler Administration: With desktop virtualization, IT teams can manage computing needs more efficiently. Maintaining a single VM template for employees with similar roles or functions simplifies updates and patches, saving time and IT resources. This centralized management helps decrease the complexity associated with maintaining individual computers.
-
Cost Savings: Desktop virtualization can shift IT budget allocations from capital expenditures to operating expenditures. Compute-intensive applications require less processing power on end-user devices when delivered through VMs hosted on data center servers. This can extend the lifespan of older or less powerful devices. Cloud-based Desktop-as-a-Service (DaaS) solutions offer a pay-as-you-go model, making them a cost-effective alternative to significant initial investments in on-premise infrastructure.
-
Improved Productivity: Employees benefit from easier access to enterprise computing resources. They can work from any location, at any time, using any supported device with an internet connection. This flexibility can boost both productivity and job satisfaction.
-
Support for Many Different Device Types: Virtual desktops can be accessed from various devices, including laptops, desktops, thin clients, zero clients, tablets, and mobile phones. This versatility allows users to enjoy a full desktop experience anywhere, regardless of the operating system of their device.
-
Agility and Scalability: Deploying new virtual machines or applications is quick and easy, and they can be just as easily removed when no longer needed. This scalability allows businesses to adapt quickly to shifting needs and demands.
-
Better End-User Experiences: Users benefit from a feature-rich experience without losing functionality they rely on, such as printing or access to USB ports. Desktop virtualization ensures that the user experience remains consistent and reliable, no matter the device used.
Best Cybersecurity Practices for Desktop Virtualization
Maintain a secure virtual desktop environment by implementing a well-rounded cybersecurity strategy that includes:
-
Superior Firewall Protection: The firewall is the first line of defense against cyber threats. Ensure your virtual desktop provider offers advanced firewall protection to protect your network from unauthorized access and cyberattacks.
-
Identity Management Protection: Implementing strong identity management is crucial for desktop virtualization. Use single sign-on (SSO) with multi-factor authentication (MFA) to verify user identities and mitigate the risk of unauthorized access.
-
Web Browser and Device Security: Role-based access control (RBAC) must be used to restrict access to specific web browsers and applications based on job responsibilities. Additionally, remote wipe and device lock capabilities should be enabled to enhance security for devices used to access virtual desktops.
-
Malware and Virus Protection: Deploy comprehensive malware and virus protection solutions to stay ahead of evolving threats. Partner with vendors that provide continuous updates and advanced protection against sophisticated malware and viruses.
-
Remote Management: Centralize the monitoring and management of virtual desktop systems. This allows for round-the-clock oversight of workstations, network equipment, and servers, enabling quick identification and response to suspicious activities.
-
Data Backups: Regularly back up data and applications to ensure quick recovery in case of a security breach. Automatic backups provide peace of mind and enhance the resilience of your virtual desktop infrastructure.
-
Mobile Device Protection: As employees increasingly use personal devices for work, it’s vital to manage and monitor these devices to maintain security. Implement solutions that allow centralized control over these devices to ensure compliance with security policies.
-
DDoS Detection: Utilize advanced tools to detect and mitigate distributed denial-of-service (DDoS) attacks.
-
BYOD Considerations: Implement a comprehensive Bring Your Own Device (BYOD) policy to manage personal devices securely. This includes establishing clear policies for device use, providing training, and ensuring limited access based on job roles. Centralize security management for these devices, using cloud-based virtual desktops to reduce risk, and have a robust process for decommissioning devices when employees leave the organization.
