What is Parallels Remote Application Server?
Parallels Remote Application Server provides vendor independent virtual desktop and application
delivery from a single platform. Accessible from anywhere with native clients and web enabled
solutions, like the Parallels RAS HTML5 Gateway, Parallels Remote Application Server allows you to
publish full desktops, applications and documents within a virtual environment, improving desktop
manageability, security and performance.
Parallels Remote Application Server extends Windows Terminal Services by using a customized
shell and virtual channel extensions over the Microsoft RDP protocol. It supports all major
Hypervisors from Microsoft, VMware, and others enabling the publishing of virtual desktops and
applications to the Parallels Client.
The product includes powerful universal printing and scanning functionality, high capacity resource
based load balancing and management features.
With the Parallels Client Manager Module for Parallels Remote Application Server you can also
centrally manage user connections and PCs converted into thin clients using the free Parallels
Client.
How does it work?
When a user requests a virtual desktop or application, the system finds a virtual guest on one of the
least loaded VDI hosts, or it finds a least loaded terminal server, and starts or restores an RDP
connection with it. Using Microsoft RDP protocol, the virtual desktop or published application is
presented to the user.
Introduction to Parallels Remote Application Server
Users can connect to the Parallels Remote Application Server using Parallels Client (available at no
charge), which can run on Windows, Linux, OS X, Android, Chrome, and iOS. Users can also
connect via an HTML5 browser or Chromebook.
As newer versions of Windows keep on being developed as time goes by, how can you defend the
migration cost to your business? Parallels Remote Application Server can help. Desktop
replacement allows you to extend the lifespan of your hardware and delay migration to the latest
OSs to a time that suits you best. The Parallels Remote Application Server solution allows you to be
very flexible: you can lock machine configurations on the user side, placing your corporate data in
an extremely secure position; or you can opt to allow users to run some local and remote
applications. Parallels Client Desktop Replacement is able to reduce the operability of the local
machine by disabling the most common local configuration options, while guaranteeing the same
level of service and security afforded by thin clients, directly from your existing PCs.

simultaneously, one acting as the master and the
others as slaves. The higher the number of HALB
appliances available, the lower the probability that
users will experience downtime. Master and slave
appliances share a common or virtual IP, also known
as VIP. Should the master HALB appliance fail, a
slave is promoted to master and takes its place
seamlessly without affecting the end user's
connection.

Parallels Remote Application Server Console
One of the fundamental features of Parallels Remote Application Server is the ability to publish
seamless applications individually to your users. This means users will only see the applications you
give them access to and not a full terminal service desktop.
The Parallels Remote Application Server Console is where you manage Parallels Remote
Application Server. Use the console to publish an application or a desktop, add a terminal server of
a VDI host to the farm, backup the Parallels Remote Application Server configuration and other
configuration changes.
Getting Started with Parallels Remote Application Sever
Parallels Remote Application Server Console Layout
The RAS Console consists of the following sections:
This section lists categories. Selecting a category will populate the right pane with
elements relevant to this category.
This section becomes available only for the Farm and the Publishing categories.
The navigation tree allows you to browse through the objects related to that
category.
This section displays the selected object or category properties, such as servers in
a farm or published application properties.
This information bar displays the site you are currently logged into and the user
account being used for the connection. Please also note the "Press Apply to
commit the new settings" message in the middle (in red). The message is displayed
when you made changes to one or more objects/items, but did not commit them
to Parallels Remote Application Server. Click the Apply button (at the bottom of the
screen) to commit the changes. If there are no currently pending changes, the
message is not displayed.
25
Getting Started with Parallels Remote Application Sever
The information bar at the bottom of the screen is used to display the most recent
console notification (if one is available).
Setting Up a Simple RAS Environment
In this section, we'll set up a simple Parallels Remote Application Server environment where all
required components run on a single server. Once you are familiar with the basic principles of
setting up a Parallels RAS environment, you can use the instructions provided here as a basis for
setting up a more advanced multi-server environment according to your needs.
To set up a Parallels RAS environment:
1 Log into the Parallels Remote Application Server console.
2 In the console, select the Start category. This category gives you access to three wizards that
you can use to easily perform essential tasks, such as adding terminal servers, publishing
applications, and inviting users to use those applications.
26
Getting Started with Parallels Remote Application Sever
Add a Terminal Server
First, we need to add a Terminal Server to the site. In this tutorial, we'll add the local server on
which Parallels Remote Application Server is installed.
To add a Terminal Server:
1 Click the Add Terminal Servers item. The Add Terminal Servers wizard opens.
2 On the first page, select the local server in the list or type the host name in the edit box at the
bottom of the page and then click the plus-sign icon.
3 Click Next.
4 On the next page, you can specify whether the firewall should be configured on the server and
the RDS role should be installed (and some others). Keep the default values and click Next.
5 Review the settings and click Next.
6 The Install Terminal Server Agent dialog opens. When the Terminal Server Agent is installed
on the server, click Done to close the dialog.
27
Getting Started with Parallels Remote Application Sever
7 Click Finish to close the wizard.
If you would like to verify that the Terminal Server has been added to the site, click the Farm
category (below the Start category) and then click Terminal Servers in the navigation tree (the
middle pane). The server should now be included in the Terminal Servers list. The Agent State
column may display a warning message. If it does, reboot the server. The Agent State column
should now say, "Agent OK", which means that your Terminal Server is fully operational.
Publish an Application
Now that you have a Terminal Server, you need to publish an application that it will serve to the
users. In this example, we'll publish the RAS Console application (you can publish any other
application that's available on the server if you like).
To publish an application:
1 Click the Publish Applications item.
Note: If you see a message box saying that there are no servers available, make sure that you added
the server as a Terminal Server to the site and then restarted it.
2 The Publish Applications wizard opens.
3 The first page of the wizard will not be displayed if you have just one Terminal Server. If you
have more than one Terminal Server, the page will be displayed and you can select the Terminal
Server(s) from which the application should be published. For instance, you can select the
Individual Servers option and then select the local server in the list.
4On the next page, navigate to Parallels / Parallels Remote Application Server and select the
Parallels Remote Application Server Console application (or any other application that you
want to publish).
If you have more than one Terminal Server and select more than one server on the previous
screen, the Show applications not available on all target servers option becomes enabled. If
the option is cleared (default), the directory tree will contain applications that are available on
each and every server that you selected. If the option is selected, the tree will contain
applications that may be available on some server(s), but not on the others.
5 Click Next. Review the summary information and click Next again.
6 Click Finish when ready.
7 To verify that the application has been published, select the Publishing category and see that
the Parallels Remote Application Server Console application is present in the Published
Resources list (the middle pane).
Invite Users
Your Parallels RAS environment is now fully operational. You have a Terminal Server and a
published application. All you need to do now is invite your users to install the Parallels Client
software on their devices, which will enable them to use the published application.
28
Getting Started with Parallels Remote Application Sever
To invite users:
1 Click the Invite Users item. The Invite Users wizard opens.
2 If you haven't configured anything yet in your Parallels RAS installation, the first wizard page will
prompt you to configure a mailbox for sending notifications to your users.
3 Enter your outgoing mail server name and sender address (e.g. your email address). Choose
whether to use the TLS/SSL protocol and whether your SMTP server requires authentication
(provide the username and password if it does). You can also send a test email to test your
outgoing mail server settings.
4 Click Next.
5 On the next page of the wizard, specify target devices and connection options:
• In the target devices list, select the types of devices to send an invitation to. Each target
device of a particular type will receive an email with instructions on how to download, install,
and configure the Parallels Client software on that device type.
• In the Public Gateway IP field, specify the RAS Secure Client Gateway domain name or IP
address. Please note that this can be a public IP address in order to reach the system from
a remote user. You can click the [...] button to select a gateway from the list.
29
Getting Started with Parallels Remote Application Sever
• In the Connection Mode drop-down list, select the RAS Secure Client Gateway connection
mode. Please note that SSL modes require the gateway to have SSL configured.
6 Click Next.
