Hybrid work drives new criteria for VDI and DaaS

Introduction

As hybrid work models gain traction, businesses are re-evaluating their IT infrastructure to support a more flexible workforce. The rise of remote and on-site work demands solutions that offer both accessibility and security.

When considering options, understanding the difference between VDI and DaaS is essential, as each offers unique benefits suited to specific operational needs. Virtual Desktop Infrastructure (VDI) and Desktop as a Service (DaaS) serve as prominent choices, with distinct approaches to accessibility, scalability, and management.

Evaluating these solutions based on new criteria is crucial for organisations aiming to enhance productivity while managing costs and resources effectively.

What is VDI (Virtual Desktop Infrastructure)?

VDI allows you to access your work desktop from any device, such as a computer, tablet, or smartphone. This setup eliminates the need for physical machines, as your company’s desktop environment is hosted on centralised servers in a data centre.

With VDI, you can use a secure desktop client or web browser to access your files, applications, and services. This allows you to operate from anywhere while protecting and managing critical data centrally.

What is DaaS (Desktop-as-a-Service)?

DaaS is a cloud-based solution that provides you with a complete virtual desktop environment. This includes the operating system, applications, files, and personal settings—all hosted by a cloud provider.

With DaaS, you can access your desktop from various devices, ensuring you have the same work experience whether you are using a PC, laptop, or tablet. This service is especially beneficial for organisations with remote or mobile workers, as it simplifies software management and updates.

Impact of hybrid work on VDI and DaaS

Understanding the difference between DaaS and VDI is essential as businesses adapt to this new work model, with each technology offering unique benefits to meet evolving workplace needs. Several factors now drive the need for these technologies, from enhancing remote access to ensuring secure and efficient management of IT resources.

Flexibility and accessibility

Hybrid work requires that employees access their work environments from various locations and devices, such as tablets, laptops, and smartphones. VDI and DaaS allow users to access a complete virtual desktop with all necessary applications and data from anywhere, making it easier for employees to work effectively regardless of where they are.

Security

With employees accessing company resources remotely, security becomes a top priority. VDI and DaaS provide a secure way to manage sensitive data since all information is processed and stored in a centralised location.

Cost-efficiency

VDI and DaaS assist firms in optimising resource consumption by allowing them to scale resources in response to demand, lowering hardware and maintenance expenses.

Enhanced user experience

VDI and DaaS ensure that employees have quick access to applications and tools, regardless of their location, which improves productivity and satisfaction.

New criteria for evaluating VDI solutions & DaaS solutions

When choosing between Virtual Desktop Infrastructure (VDI) and Desktop as a Service (DaaS), consider the following criteria:

• Organisational capabilities: Assess whether you have the necessary IT expertise and resources. If not, DaaS may be more suitable.
• Platform: Consider how often you need updates. VDI provides stability but requires manual updates, while DaaS offers rapid improvements but relies on a stable internet connection.
• Cost: Understand your budget and usage patterns. VDI might be more cost-effective for predictable growth, while DaaS offers flexibility in spending.
• Agility/Elasticity: Think about your staffing needs. If you have temporary or fluctuating requirements, DaaS allows you to quickly adjust user numbers.
• Geography: Evaluate where your users are located. DaaS can provide global support with minimal latency, while VDI may require multiple local deployments.

Benefits of VDI and DaaS in hybrid work

VDI DaaS offers various benefits for a hybrid work setup, such as:

Challenges and considerations of VDI and DaaS

Here are the key challenges to consider when understanding the difference between VDI and DaaS:

• Performance and scalability: VDI requires more resources per user than traditional PCs, so you need enough CPU (central processing unit), RAM (random access memory), and disk speed to support multiple users simultaneously. 
• Administration and updates: Performing updates manually on each virtual machine is time-consuming and can lead to errors.
• Security: With all data processed in a virtual environment, it’s challenging to protect user information during transmission and storage.
• Cost considerations: Setting up a VDI environment involves substantial initial investment and ongoing operating costs. You need to consider expenses for servers, storage, networking equipment, and software licences.

Best practices for VDI and DaaS

Following these best practices for VDI DaaS will help ensure a smooth and successful implementation:

• Evaluate cloud readiness: Determine internet bandwidth and identify any skill gaps in your team that may need addressing.
• Define a cloud strategy: Establish clear objectives for your cloud migration, such as cost savings and improved performance.
• Select the right cloud model: Choose the cloud deployment model that fits your needs.
• Public cloud: Fully managed by a cloud provider, ideal for scalability.
• Private cloud: Dedicated resources for tighter security and control.
• Hybrid cloud: Combines both public and private options for flexibility.
• Implement security controls: Adopt a zero-trust approach, where security is prioritised at every level. Focus on identity management, data protection, and monitoring to guard against threats.
• Design for operational excellence: Automate processes such as scaling resources and updates to ensure efficiency. Use cloud-native management tools for better performance and ease of use.
• Manage costs effectively: Create a centralised self-service catalogue for resource requests. Set up policies to control usage and prevent overspending. Monitor expenses regularly to identify and eliminate waste.

Future trends of VDI and DaaS

Here are some key trends and opportunities that you should be aware of:

• Rise of flexible services: The Great Resignation is driving companies to seek flexible work solutions. Increased reliance on external services and remote access to virtual desktops is becoming the norm.
• Opportunities for SMBs: Small and Medium-Sized Businesses (SMBs) are leveraging DaaS to enhance their competitiveness. Secure cloud storage and features like "point in time" restoration simplify data management and recovery.
• Business continuity and cybersecurity: As cyber threats rise, organisations are integrating VDI into their business continuity plans. VDI serves as a backup solution to ensure productivity during cyberattacks.
• Addressing staffing gaps: VDI and DaaS help tackle workforce shortages by enabling companies to hire talent regardless of location, fostering employee loyalty and productivity.
