VDI vs RDS

Which Fits Your Business?

VDI and RDS can help organizations grow by enabling central management, adherence to regulations, and increase infrastructure flexibility. Why choose only one when you can have both under the same solution?

Utilize both VDI and RDS technologies to build a flexible infrastructure that fits your needs.

Application and desktop virtualization has become an irresistible option for businesses looking to optimize resources, provide mobile solutions and deliver a consistent user experience.

Depending on their virtualization needs, companies may want to mix and match virtual desktop infrastructure (VDI) and Remote Desktop Services (RDS) technologies.

While both have their pros and cons, they each hold a specific purpose. Businesses need to decide which solution is the right one for their virtualization requirements, taking into consideration their current and future needs.

Parallels® Remote Application Server (RAS) allows businesses to deploy both technologies without additional costs, which saves IT administrators from making a difficult choice at the very start of their migration project.

VDI vs RDS

Which Best Fits Your Scenario?

VDI and RDS offer about the same virtualization benefits, but their design and infrastructure are different to serve various business scenarios.

RDS VDI
Provides a dedicated virtual machine (VM) for each user in the infrastructure. X
Provides a simple deployment where operating system and application updates take place centrally. X
Users have to share the RD Session Hosts and VMs or create new ones manually. X
Administrative rights are not entirely secure, as sharing resources between multiple users takes place for a fully functional environment. X
The cost and complexity might be a concern, depending on the business needs and budget (e.g., number of employees, annual turnover, etc.). X
Managing the infrastructure and backups is easy. X
Resource management is easier, as the utilization of central processing units (CPU) and memory resources is lower, which facilitates having more users per system. X

How is VDI different from RDS?

When using VDI, a pool of virtual desktop servers are configured using virtualization software. Unlike RDS, which is limited to Windows Server, VDI is not limited to a single operating system or a single application architecture.

RDS runs on a single server and users access it through a network connection and Remote Desktop Protocol. With VDI, each user receives their own virtual server. Individual OS instances are hosted on VDI VMs with associated applications and data.

Administration is simplified with VDI, as a single master image is configured and updated. When using RDS, the desktop image you configure on the server is cloned and presented to users with all of its associated applications and data.

VDI has persistent and non-persistent desktops. Persistent desktops allow personalization with custom application installs and OS configurations, while with non-persistent desktops, users are given a randomly assigned desktop from the pool.
