Term/Abbreviation

Description

RAS Console

Parallels RAS Console.

The RAS console is the primary interface you use to configure, manage, and run Parallels RAS. As an administrator, you use the RAS console to manage Farms, Sites, RD Session Hosts, published resources, client connections, etc.

Category

In the RAS console, categories are displayed in the left pane of the main window. Each category consists of a number of settings related to a specific task or operation.

The categories include Start, Farm, Load Balancing, Publishing, Universal Printing, Universal Scanning, Connection, Device Manager, and others.

Farm

A Parallels RAS Farm is a logical grouping of objects for the purpose of centralized management. A Farm configuration is stored in a single database which contains information about all objects comprising the Farm. A Farm consists of at least one Site but may have as many sites as necessary (see Site below).

Site

A Site consists of at least one RAS Connection Broker, RAS Secure Gateway (or multiple gateways), and RAS agents installed on RD Session Hosts, Providers, and Windows PCs. Note that a given RD Session Host, Provider, or PC can be a member of only one Site at any given time.

Licensing Site

The Site that manages Parallels RAS licenses in a Parallels RAS Farm. By default, the server on which you install Parallels RAS becomes the Licensing Site. If you create additional sites later, you can designate any one of them as the Licensing Site.

There can be only one Licensing Site in a given Farm. All other sites are called secondary sites.

Note: Parallels RAS updates or upgrades must be applied to the Licensing Site first.

RAS Secure Gateway

RAS Secure Gateway tunnels all traffic needed by applications on a single port and provides secure connections.

Web Client

Web Client allows users to view and launch remote applications and desktops in a web browser. The Web Client functionality is a part of RAS Secure Gateway.

Publishing

The act of making items installed on a Remote Desktop Server, Provider or Remote PC available to the users via Parallels RAS.

RAS Connection Broker

RAS Connection Broker provides load balancing of published applications and desktops.

RAS RD Session Host Agent

RAS RD Session Host Agent collects information from Microsoft RDS hosts required by the Connection Broker and transmits to it when required.

Remote PC Agent

Remote PC Agent collects information from Remote PC hosts required by the Connection Broker and transmits to it when required.

RAS Guest Agent

RAS Guest Agent collects information from the VDI desktop required by RAS Connection Broker and transmits to it when required.

RAS Provider Agent / RAS Provider Agent

RAS Provider Agent collects information from the Parallels RAS Infrastructure and is responsible for controlling VDI through its native API. RAS Provider Agent is built into the RAS Connection Broker and is available by default. It can be used to control multiple Providers in a Parallels RAS Farm.

RAS Provider Agent is the same as RAS Provider Agent, but the term is used in the context of Azure Virtual Desktop (described at the end of this table).

RAS Provider Agent dedicated

RAS Provider Agent dedicated is similar to the RAS Provider Agent described above with one important difference — it is a separate component that must be installed from the Parallels RAS installer and can only control a single Provider.

RDSH or RD Session Host

RDSH makes applications and a full desktop accessible to a remote client that supports Remote Desktop Protocol (RDP). RDSH replaced Terminal Servicer beginning with Windows 2008 R2.

HALB

High Availability Load Balancing (HALB) is an appliance that provides load balancing for RAS Secure Gateways. Parallels HALB virtual appliance is available for the following hypervisors: Hyper-V, VMware. Multiple HALB Virtual Servers representing different HALB devices can be deployed in a single Site.

Multiple HALB deployments can run simultaneously, one acting as the primary and others as secondaries. The more HALB deployments a Site has, the lower the probability that end users will experience downtime. Primary and secondary HALB deployments share a common or virtual IP address (VIP). Should the primary HALB deployment fail, a secondary is promoted to primary and takes its place.

Tenant Broker

Tenant Broker is a special RAS installation that hosts shared RAS Secure Gateways. It is an essential part of the RAS multi-tenant architecture.

Tenant

Tenants are RAS farms that join Tenant Broker (see above) and use shared RAS Secure Gateways and HALB thus eliminating the need to have their own Gateways and HALB deployed.

RAS Enrollment Server

RAS Enrollment Server is an essential component of the SAML SSO Authentication functionality. It communicates with Microsoft Certificate Authority (CA) to request, enroll, and manage digital certificates on behalf of the user for SSO authentication in the Parallels RAS environment.

RAS PowerShell

Parallels RAS PowerShell allows you to perform Parallels RAS administrative tasks using PowerShell cmdlets. You can execute cmdlets in the Windows PowerShell console or you can write scripts to perform common Parallels RAS administrative tasks. A complete guide to Parallels RAS PowerShell is available on the Parallels website together with other Parallels RAS documentation.

RAS REST API

Parallels RAS comes with various APIs to help you develop custom applications that integrate with it. The RAS REST API is one of them.

RAS Management Portal

Parallels RAS Management Portal is an HTML5 browser-based application that lets you manage Parallels RAS.

RAS Web Administration Service

A Web service that provides the user interface for RAS Management Portal and implements RESTful Web services for the RAS REST API (see above).

Azure Virtual Desktop

Azure Virtual Desktop is a desktop and app virtualization service running on Microsoft Azure, providing access to RD Session Hosts and VDI. Parallels RAS 18 provides the ability to integrate, configure, maintain, support and access Azure Virtual Desktop workloads on top of the existing technical capabilities of Parallels RAS.

FSLogix

FSLogix Profile Container is a remote profile solution for non-persistent environments. Parallels RAS supports FSLogix on RD Session Hosts, VDI, and Azure Virtual Desktop.
