What is Desktop-as-a-Service (DaaS)?
Desktop-as-a-Service (DaaS) is a virtual desktop hosted entirely on cloud-based infrastructure that is accessible from any web browser with an internet connection.
When combined with a bring-your-own-device model, DaaS can reduce capital expenditures (CAPEX), and allow IT teams to focus on tasks other than provisioning and reprovisioning computing devices repeatedly. Virtual machines also typically have better processing power than traditional computing devices, as they can access cloud compute services and infrastructure that spread tasks over multiple servers to increase computing power.
A virtual desktop infrastructure (VDI) enables companies to safeguard data and software from catastrophic events such as fire and flood. With traditional deployment of IT resources, the data stored on a user’s computer is physically stored on that device, and often is not backed up regularly. If it happened to be damaged in a fire, it would be difficult to retrieve the data, and the company would be out time and money in the process. After implementing VDI deployment, organizations will be able to enact disaster recovery plans more swiftly, as all data is stored on the cloud with a DaaS solution.
Desktop virtualization does not, however, mean a decrease in data security. Like utilizing computing devices on-premises, VDI allows for complete control of the end user environment. Cloud infrastructure is also typically protected against data loss through duplication across geographic regions, and most cloud services ensure that there is limited, authorized access to servers that store their clients’ data.
There are multiple options available to choose from when looking for a DaaS solution. Citrix Virtual Apps and Desktops can deliver Windows and Linux operating systems through the cloud, as can Amazon Workspaces, Microsoft Azure, and VMware Horizon Cloud. These remote desktops can be quickly provisioned, typically in approximately three days, and allow for an improved user experience, as they can access be accessed from whatever device users prefer, rather than being stuck to a single piece of hardware or operating system.
Business benefits of desktop-as-a-service offerings include:
- Streamline processes: Rather than having to provision new computers every time a new employee or contractor is brought on, IT can simply enable a new virtual desktop. This also minimizes the work that IT employees must do around physical computer management, allowing them to focus on other tasks.
- Scalability: Cloud services make it easy to deploy or remove virtual desktops. During a busy season when temporary employees are needed, companies will not need to purchase new computers, and then be stuck holding on to them after the temporary employees leave. Instead, organizations can add and remove virtual desktops as needed.
- Stronger data security: Organizations can minimize data loss due to catastrophic events, as well as better secure their data against malicious attacks using VDI. Additionally, software maintenance is easier through self-healing processes available through most cloud service providers’ DaaS offerings.
- Enhanced mobility and flexibility: Rather being tied to a single device in a designated location, users have the option to choose their preferred device (such as a mac, PC, or tablet), and can access their virtual desktop at anytime from anywhere.
