While the darkest days of lockdown are hopefully behind us, many businesses plan to continue supporting work from home. The ad-hoc approach won’t do as a long-term solution, though; virtual desktop infrastructure (VDI) services provide a secure and manageable alternative.

It’s a market with plenty of mature products to choose from, but Parallels Remote Application Server 18 (RAS) stands out with a wealth of features aimed at improving life for both workers and administrators. The platform takes care of all VDI and application delivery services, with support for FSLogix Profile Containers for easier user configuration, and the whole thing integrates with Windows Virtual Desktop (WVD), so it can be managed from a single console.

Even better, users can keep the benefit of working on their preferred hardware: Parallels provides clients for Windows, macOS, Linux, iOS, Android and Chrome OS, and there’s even an HTML5 client for accessing services using a compliant browser.

If you want to test-drive RAS, it’s available as a free 30-day trial, and can be hosted either locally or on AWS or Azure. We tested using Azure and found deployment admirably swift: the setup procedure created a new Windows Server 2019 VM in the cloud for us, and pre-loaded all necessary components and services, such as Azure Active Directory (AD) for role-based access control.

The desktop console app provides access to management services; here you’ll find wizards for adding Windows Remote Desktop session hosts to your site, publishing applications and sending email invitations to users, which include client download and login instructions. Parallels is developing a web-based portal too – it’s a work in progress right now, but as more features are migrated across, it’s intended to eventually become the primary management tool.

Publishing apps is simple. You just need to choose which servers to publish from, then pick the desired apps from the list presented. RAS defaults to permitting app access to everyone, but a filtering option lets you lock this down to specific AD groups or users.

From the Farm tab you can view all sites, deploy Azure WVD providers and add other VDI hosts, with support for all popular hypervisors. You can keep close tabs on site performance too, with graphs showing server CPU, memory and storage utilisation. To help further optimise performance, the new UX Evaluator and Advanced Session Details features provide over 25 metrics for monitoring user experience, including time between a user loading a resource and the response, connection quality and latency. You can set alerts and thresholds to warn of any issues, and export data for further analysis.


DevOps: A view from the enterprise

From the user’s point of view, getting started with RAS is almost effortless. Once they’ve installed the client they just need to authenticate: RAS supports multifactor, SAML SSO or smart card authentication, and policies with custom settings can be pushed to users and groups. The RAS Windows client integrates with the standard WVD client, so users can run Windows virtual desktop sessions and access published apps from the same console. We found we could start apps directly from the client or pin shortcuts conveniently to our local desktop, and open them by either double-clicking or dropping local or remote files onto them.

We also appreciated that during Windows virtual desktop sessions our local drives were redirected for easy access from within the session, and we could create remote shared folders for everyone to use. This latest release of RAS includes a new accelerated file retrieval feature for Windows and macOS, which uses caching on redirected drives to improve copy performance.

Parallels RAS 18 is a great choice for businesses transitioning to hybrid working. It’s easy to set up, with fully centralised management and strong access security. Workers, meanwhile, get seamless access to the apps they need on the devices of their choosing – and costs can be easily managed, as pricing is based solely on the number of concurrent users.
