A company needs to supply Windows desktops to 250 employees who will be working from home for at least the next year. Management wants to avoid purchasing and maintaining new server hardware in the datacenter, and users must be able to reach their desktops securely over the public Internet through a web client or thin client-without installing a VPN. Which of the following solutions would BEST meet these requirements?
Cloud-hosted virtual desktop infrastructure (Desktop as a Service)
Application virtualization/streaming
Building a private cloud in the company datacenter
A cloud-hosted virtual desktop infrastructure-often sold as Desktop as a Service (DaaS)-runs the VDI control plane and desktop VMs in a public cloud provider's data center. The provider handles the hypervisors, storage, and network connectivity, so the company does not need to deploy or maintain on-premises virtualization hosts. Employees connect over the Internet using HTTPS/RDP/ICA clients, eliminating the need for a VPN while still allowing IT to centrally manage images and policies.
An on-premises VDI deployment still requires the organization to purchase, rack, and manage virtualization servers and storage. Application virtualization delivers only individual apps, not full desktops, and a private-cloud build would again entail running the infrastructure in the company's own facility.
