虚拟桌面架构（VDI）

Protect corporate data with central file storage, granular expression-based filtering policies, encryption controls, and support for one or more multi-factor authentication (MFA) providers in the same Parallels RAS site.

Parallels RAS extends and simplifies the capabilities of Azure Virtual Desktop (AVD) by integrating and managing all workloads and resources from a central point—the Parallels RAS Console. IT administrators can streamline, provision and manage AVD workloads and components via wizards.

Parallels RAS provides efficient and streamlined delivery for virtual apps and desktops with more than 130 built-in automated optimization capabilities. Administrators can leverage pre-configured optimizations for VDI, RDSH, or Azure Virtual Desktop workloads depending on the server type, and use scripts, including third-party tools, saving time in optimizing images.

Parallels RAS provides the ability to deploy clones from templates to the local disks of multiple independent Microsoft Hyper-V hosts, rather than only using centrally shared storage such as SAN. Benefits include reduced need for complex configurations, the ability to maintain a single template for use with multiple providers, and faster disk access.

Parallels RAS supports the provisioning of VDI and Remote Desktop Session Host (RDSH) workloads directly on Microsoft Azure as a VDI platform. This enables organizations to create, scale, and manage required workloads on demand, directly on Microsoft Azure, rendering faster deployments, simplifying management, and reducing costs.

Admins can set a preconfigured number of VMs to be created based on a RAS template to ensure that enough VDI instances are available for users, ready to accept users’ connections, and reduce login times. IT can define an alive timer, and after the predefined time expires, the VM is deleted from the infrastructure, freeing valuable storage space.

VM pools offer administrators flexibility when managing a vast number of guest VMs. IT administrators can set multiple pools based on guest VMs from specific RAS templates and provide access to different user groups. Each group can have a virtual desktop template with specific requirements, simplifying account management on the IT side.

Parallels RAS offers two types of VDI options: persistent and non-persistent.

• Persistent VDI is uniquely customizable and carries over from one user session to another. User data is retained and always available through any user session. Non-persistent VDI creates a standard desktop from a Parallels RAS template with static settings and is deleted upon user logout or expiry of alive timer.
