DaaS, VDI, and the Changing World of the Desktop

VDI or Virtual Desktop Infrastructure 

Virtual Desktop Infrastructure is older than these widely available options in the market. Companies have traditionally used VDI for data hosting. In this arrangement, VDI does not involve a public cloud approach. In a traditional on-site VDI, a central server on the premise hosts virtual desktops for corporate use. This arrangement can work wonders for businesses concerned with privacy. Virtual Desktop Infrastructure is a popular choice among many businesses because it enables them to host data on-premises. On-premise hosting is often considered safer or a requirement in certain sectors. 

Businesses that work with sensitive information tend to exercise complete control over their data. Outsourcing data storage is sometimes seen as a loss of vital control. All companies have data they consider mission-critical, and keeping such data on an on-premise server is the norm. Due to issues of data breaches and cybersecurity complexities, businesses worry that data hosted on third-party (cloud) servers may not be in their best interest. Thus, the use of on-premise VDI is often linked to trust issues. 

DaaS or Desktop as a Service 

Unlike Virtual Desktop Infrastructure, DaaS or Desktop as a Service is a recent addition to the evolving desktop market. DaaS also involves virtualization and delivers virtual desktops to users. The key difference, however, lies in the dynamics of its deployment. When first introduced, the market did not warm up to the idea of Desktop as a Service. Traditionally, desktop – physical or virtual – was still understood as a product and not a service. Lately, however, DaaS has emerged as a more secure and cost-effective alternative to Virtual Desktop Infrastructure.  

 DaaS is a managed service that is provided by third-party Cloud Services Providers (CSPs). Like an on-site VDI, DaaS delivers virtual desktops to businesses that can be customized per specific business requirements. Unlike VDI, however, DaaS involves the storage of virtual desktops on cloud servers located off-premises. CSPs own or manage these servers and are found in isolated locations for security reasons. In DaaS, virtual desktops are deployed and managed by third-party providers, so they take care of every IT-related task. It reduces costs and the need to rely on office infrastructure for heavy-duty computing.  

Virtual Desktop Infrastructure and Desktop as a Service 

Both DaaS and VDI have evolved as popular choices among businesses. However, they have some differences that need to be kept in mind. The table below summarizes their differences. It also contains details you need to know about each of these before deploying either: 

Virtual Desktop Infrastructure Desktop as a Service
Virtual desktops are hosted on a local, on-premises server. Virtual desktops are hosted on cloud servers under third-party management.
In-house IT is responsible for the deployment, management, maintenance, and updates.   Managed end-to-end as a service by a third-party cloud service provider. The provider takes care of everything.
Use of on-premises VDI is typically restricted to office premises.   DaaS has zero access restrictions and can be accessed from anywhere.
In-house IT is responsible for management. Third-party CSPs are responsible for management and security.
On-premises VDI requires huge capital expenditure in the form of office hardware. DaaS offers pay-as-you-go pricing plans and requires no in-house server.

 

Other Features of DaaS 

From the table above, DaaS stands out for many reasons, including expert management and cost savings. Let’s look at two other features of DaaS that can explain the rise in its popularity among modern-day businesses around the world: 

  • Industry-leading Security Standards 

Unlike physical desktops, DaaS-enable virtual desktops are automatically protected from wear and tear processes. They cannot be stolen, either. Although these offer some peace of mind, they are no guarantee for all-around security. With digital security breaches becoming sophisticated daily, DaaS providers emphasize a multi-layer secured environment to host virtual desktops.

It has become a basic requirement for many businesses willing to host confidential data on third-party servers. A multi-layered security approach includes physical measures such as isolated data centers under 24X7 surveillance and numerous digital security measures.

As it is, cloud desktops are not prone to theft or physical wear like their counterparts. Security best practices include firewalls, MFA (multi-factor authentication), IP restrictions, and 256-bit data encryption protection against DDoS (denial-of-service) attacks, OS-hardening, OS-patching, SSL (Secure Sockets Layer), ransomware best practices, antivirus software, and many more. 

  • Easy Scalability Options 

On-premises VDI has not been able to keep up with the pressures of remote working. Workplace flexibility has become the norm in many organizations and a basic expectation for the majority of today’s workforce.

In light of this, the incremental cost of purchasing hardware to suit the growing needs of an organization is ultimately quite untenable. DaaS brings in the option of built-in scalability to cope with the growing demands of any business. Whether the workforce increases, decreases or goes remote, DaaS can successfully respond to a flexible workforce and seasonal workloads.

The needs for a hybrid workforce keep changing, and with most businesses relying on them, the mode of doing business has also changed greatly. DaaS has become a profitable way of doing business by ensuring workforce productivity under all circumstances.  

In Conclusion 

Recently, DaaS has grown in popularity because many businesses have warmed up to its major benefits. Though seemingly daunting, data hosting on third-party servers has evolved greatly over the years to become one of the safest data storage means.

It tells us a lot about how much the technology behind DaaS has improved over the years. DaaS has conquered fears regarding data hosting on third-party servers in recent years. DaaS providers have also implemented best-in-class security features in a timely fashion. These have quelled clients’ fears and made third-party data hosting a safe and more convenient choice for many businesses.
