Introduction

Desktop as a service is an offering of cloud owners where they provide virtual desktops to clients over the internet. In which they can manage their business more efficiently. There are various pricing models; subscription offers for Desktop as a service (DaaS). The end-users do not have to worry about infrastructure, management, and security as it is already made available. The cost of owning a virtual desktop is very costly and resource-consuming compared to a cloud desktop. In this service, we can use data and benefits from a centralized data server located remotely using a virtualized desktop.

Types of Desktop as a Service

There are two types of Desktop as a service: persistent and non-persistent.

1. Persistent Desktop

It is a virtual desktop service in which clients can customize and save the Desktop on their machine, and data will automatically save whenever the end-user logout. Also, we can adjust all data items according to us.

2. Non Persistent Desktop

In these services, the client’s data vanishes as the end-user logs out, and the data is never saved. And it just acts as a portal for shared cloud services. Non-Persistent is less expensive than persistent Desktop.

How does Desktop as a Service work?

In Desktop as a Service (DaaS), the cloud service provider hosts the network resources, storage, and infrastructure that flows the Virtual Desktop to the client’s device. The client can access the Desktop’s data and applications through a web browser or other software. Enterprise can purchase as many virtual desktops as they want through the subscription model.

As this service is used via the Internet show, it was complicated to introduce graphics and intense applications with DAAS. But with the evolution of new technologies, DAAS has improved its functionalities. When the workload on one server gets too high, IT administrators can migrate a virtual machine from one physical server to another in just a few seconds, allowing graphics accelerated or GPU-accelerated applications to run uninterrupted.

Advantages of Desktop as a Service

• Inexpensive
  It is low cost as compared to owning a desktop and laptop. Desktop as a service also requires less computing power and is highly managed with new technologies.

• Better security
  Because the data is stored and managed by a virtual desktop, so chances of security conflicts are meager. Users can focus on their business with high-security configurations. Since none of the data lives on that stolen device, the risk of thieves accessing sensitive information is minimal.

• Easy & understanding UI
  The user interface of Desktop as a service is friendly and understanding. Anyone with less technical skills and easily access services and use them.

• Reduced downtime for IT employees
  Desktop as a Service(DaaS) also allows industries to get remote IT support to their employees, reducing downtime.
