Virtual Desktop Infrastructures (VDI): Weighing the Pros and Cons for Your Business

In today’s flexible working environment, businesses are constantly looking for ways to enable seamless remote access and management. One solution that often comes up in conversation is Virtual Desktop Infrastructure, or VDI. VDI has gained popularity for its promise of centralised management, enhanced security, and device flexibility. But, like any technology, it’s not a one-size-fits-all solution. In this post, we’ll weigh the pros and cons of VDI to help you decide if it’s the right fit for your organisation.

What Exactly is VDI?

Before we dive into the nitty-gritty, let’s briefly define what VDI is. Essentially, VDI is a technology that allows you to host desktop operating systems and applications on a central server, rather than on individual computers. Users then access these virtual desktops remotely, using a variety of devices – from thin clients to laptops, tablets, and even smartphones. Think of it like streaming your desktop from the cloud.

The Upsides: Why Businesses Consider VDI

Let’s start by looking at why VDI is gaining traction with many organisations:

1. Centralised Management: This is one of the most significant advantages of VDI. Instead of managing individual desktops, IT teams can manage and maintain virtual desktops centrally. This simplifies software deployments, updates, and patching processes, reducing management overhead, and saving time. It’s much easier to keep everything up-to-date when you only have one core system to update rather than managing multiple physical devices.
2. Enhanced Security: With VDI, sensitive data is stored in a data centre, rather than on individual devices, meaning even if a device is lost or stolen, your business data remains protected. This is particularly important for industries that handle sensitive data or operate within regulated environments. Also, since the endpoint devices aren’t processing or storing the data, there is less risk of malicious software being installed on them. This approach reduces the overall attack surface, improving your overall security posture.
3. Improved Data Control and Compliance: VDI provides greater control over your organisation’s data. Because data is stored in a central location, it’s easier to implement policies and procedures related to data access and usage, this ensures your compliance with regulations or internal policies.
4. Device Flexibility and BYOD: VDI allows users to access their desktops from a variety of devices, which empowers your employees with a flexible work experience. With VDI, your employees are not tied to a particular device or operating system, supporting Bring Your Own Device (BYOD) initiatives. This increases convenience and reduces costs associated with purchasing and maintaining specific hardware types.
5. Simplified Disaster Recovery: In the event of a disaster or system failure, VDI makes disaster recovery simpler. Because virtual desktops are stored on servers in a data centre or cloud environment, they can be quickly restored, minimising downtime and business disruption. This increases business continuity.
6. Improved Software Compatibility: VDI can help manage software compatibility issues. Older or legacy applications that may not be compatible with newer operating systems can be hosted on virtual desktops without requiring a complete system update. This is especially useful if you have multiple software and apps that have varying software requirements.
7. Extended Hardware Life: With VDI, you can extend the useful life of older devices. Because the processing is done on the server, older devices can still be used to access the virtual desktops, so there’s no need to continually purchase expensive hardware.

The Downsides: Potential Challenges of VDI

While VDI offers many benefits, it’s essential to be aware of the potential drawbacks:

1. Initial Implementation Costs: Setting up a VDI environment can be a significant investment. There are costs related to hardware (servers, storage), software licences, and professional services required for setup and implementation.
2. Ongoing Infrastructure Costs: VDI infrastructure requires ongoing investment in maintenance, upgrades, and software licences. There will be ongoing operational costs associated with managing and maintaining the servers, storage, and network infrastructure which all need to be factored in.
3. Complexity of Implementation: Deploying and managing VDI environments can be complex, requiring specialised expertise. Setting up and configuring a VDI system effectively will require an experienced IT team with a deep understanding of virtualisation, networking, and security. This can make ongoing support complex for a small IT team to manage.
4. Dependence on Network Connectivity: VDI relies on a stable, fast network connection. If your users have poor network quality, they may experience latency, slow performance, or interruptions to their work.
5. User Experience Considerations: User experience is a major consideration. If VDI isn’t properly configured, performance can be slow, impacting the user’s experience. Issues such as lag, application freezes, and printing problems can become major frustrations for the end-user.
6. Resource Requirements: VDI environments can be resource intensive. They require significant processing power, memory, and storage on the central server to support multiple virtual desktops running concurrently. If the servers aren’t set up properly it could cause performance issues across the whole system.
7. Single Point of Failure: A central VDI server could become a single point of failure, and if that server experiences problems, your entire workforce can be impacted. For this reason, a robust high availability setup is required to minimise downtime.

Making the Right Choice for Your Business

Whether VDI is the right fit for your business depends on your specific needs, budget, and priorities. If you’re looking for centralised management, enhanced security, and improved data control and you have a solid IT team that can handle the complexity, VDI may be a good option for you. However, if you have a tight budget, limited IT resources, or require minimal IT overhead then VDI may not be for you.
