Parallels Remote Application Server (RAS) is a virtual application and virtual desktop infrastructure (VDI) solution that allows users to access applications and data from just about any device. Let's learn what's new in RAS v16.
Latest posts by Timothy Warner (see all)

Parallels released version 16 of its Remote Application Server (RAS) in July 2017. The key idea behind RAS is that systems administrators can manage all of their application and desktop publishing needs from one place. Moreover, users can access these resources from their tablet devices or even their smartphones.

I covered RAS v15 thoroughly in a previous 4sysops article; you may want to check it out:

Today I will show you what's new in RAS v16. Let's get started!

Parallels HTML5 Client customization

RAS users can connect to hosted applications or desktops by using either a "thick" Parallels Client, or the Parallels HTML5 Client. In RAS v16, IT administrators can now apply corporate branding and other customizations to the HTML5 client.

Branding is a big deal for many businesses who want their services to reflect their own corporate "look and feel" instead of inundating their users with different vendor-specific user interfaces.

The next screenshot shows you how to get to the HTML5 client customization settings in the RAS Console:

The next time users log into the Parallels HTML5 Client, they will see the customization. Here, let me show you:

Expanded VDI publishing options

Virtual desktop infrastructure (VDI) helps businesses save money by centralizing desktop environments. In some ways VDI is a throwback to the original days of mainframe computing in which end users had nothing but a monitor, a keyboard, and a network connection on their side.

RAS v16 adds Nutanix Acropolis and Hewlett-Packard Enterprise (HPE) to its already robust list of supported hypervisors. You can see the list in the following screenshot:

RAS v16 generates VDI desktops on the fly and on demand by virtue of an intuitive, customizable template library.

Parallels Client for iOS and Android

As I stated earlier, one of RAS v16's value propositions is that a user should be able to access applications and virtual desktops from anywhere. Parallels HTML5 Client makes RAS v16 portable, and the updated iOS and Android applications take universality one step further.

I show you a couple screenshots from the Parallels Client running on an Apple iPhone.

In addition, Parallels improved the usage of mobile devices by adding support for new input devices such as Quick Keypads and the Swiftpoint GT mouse.

Containerized applications

Although RAS simplifies the process of publishing applications over your network and even the Internet, IT administrators are nonetheless required to lay the foundation for each application (preparing applications on a terminal server, for instance).

In RAS v16, we have native integration with In case you've never heard of it, is an online repository allows the containerization and provisioning of applications.

What's different about is that all of its applications run as containers, or isolated instances with all dependencies stored within each container. Note that uses its own container engine; it does not use Docker.

The value proposition here is that it becomes a lot easier to discover apps to publish to your users. The following screenshot gives you a feel for the integration:

PowerShell automation

In 21st century IT, you won't get very far in your career as a Windows systems administrator unless you understand PowerShell. RAS v16 includes a binary module named PSAdmin that contains 110 cmdlets as of this writing.

As you can see in the following screenshot, the Parallels team took the time to document their commands—thanks for that!

Exploring the PSAdmin PowerShell module

To use the PSAdmin module, fire up an elevated PowerShell console and create a Parallels RAS session. Note: none of the commands work unless you've established a connection to your RAS server.

Let's check on the status of our RAS gateway:

ID     Site ID  Server    Gateway IPs   Description    Enabled
--     -------  ------    -----------   -----------    -------
1      1        ADBDC                     True

In my lab environment, I published only one Remote Desktop Services (RDS) application. Let's check on that:

PS C:\Users\tim> Get-PubRDSApp
Type     ID   Name       Description      Parent Id      Previous Id
----     --   ----       -----------      ---------      -----------
RDSApp   1    notepad    Application      0              0


Parallels gives you three options for evaluating Remote Application Server v16:

  • Install the trial in your data center
  • Download a preconfigured virtual machine (VM)
  • Deploy a preconfigured Microsoft Azure VM (Amazon Web Services coming soon)

RAS v16's license works like any other software-as-a-service (SaaS) app. In other words, you pay for a one-, two-, or three-year subscription, with the license cost adjusted depending on your concurrent users.

RAS v16 is a really nice product because it centralizes disparate application and desktop publishing solutions in your enterprise into a so-called "single pane of glass." What's more is that Parallels obviously spent time making the product as easy to use as they could.
