Desktop virtualization has become an inevitable option for businesses to optimize resources, provide mobility solutions, and deliver a higher level of performance. For desktop virtualization, companies can choose between VDI or RDS: either a virtual desktop infrastructure (VDI) or a remote desktop service (RDS). While both these technologies have their own strengths and weaknesses, they each have a specific purpose, and businesses need to choose the right solution for their desktop virtualization requirements based on their present and future business needs. Parallels Remote Application Server allows businesses to interchangeably use the two technologies, which avoids forcing administrators to make a difficult choice at the beginning of their cloud project.
Parallels is one of the leading providers of VDI and RDS solutions. The RDP client works in harmony with any hypervisor and RDS to provide a familiar user experience.
VDI and RDS offer more or less the same virtualization solutions but are designed to serve different business scenarios.
|Each user gets a separate VM|
|Creates complexity for the IT staff, wherein they have to manage multiple instances of the OS, updating and patching them.|
|Multiple users use the same VM and server OS|
|Does not provide complete administrative rights, as resources have to be shared between multiple users|
|Cost and complexity is a concern|
|Managing and updating the software is easy|
|Less CPU and memory resources are utilized, which facilitates having more users per system|
Virtual desktop infrastructure (VDI) involves running user desktops inside virtual machines that are hosted on datacenter servers. In a VDI environment, each user is allotted a dedicated VM that runs a separate operating system. This flexibility provides an isolated environment for the user. As each user enjoys a dedicated VM with an OS, they can install or uninstall applications with full or partial administration rights within the VM. A connection broker is used to manage these VMs. VDI is particularly useful when businesses have to deal with critical and confidential data.
Remote Desktop Service (RDS), a proprietary protocol of Microsoft, allows users to connect remotely to a network with a graphic user interface. While the RDS client is installed on the user system, the RDS server software is installed on the server, and a remote connection is established with one or more terminal servers. While users in the RDS network connect to the server using a VM, this VM is shared with other users and operates on the same server OS for all users.
VDI and RDS have peculiarities that adapt to the different needs of a business, but making a choice between them could be difficult for some companies. The optimal situation is the possibility of an infrastructure that evolves with business needs, moving between the two paradigms without extra cost. Parallels Remote Application Server allows the interchangeable use of the two technologies, which avoids forcing administrators to make a difficult choice at the beginning of their cloud project. Parallels is one of the leading providers of RDS and VDI solutions. The RDP client works in harmony with any hypervisor to provide a familiar user experience.
