What is a Virtual App? | Parallels Explains

The advent of virtualization technology has brought revolutionary changes to IT procedures. Many IT components, from servers to networks, are now virtualized. With the smartphone dominating the IT world, “virtual app” and “application virtualization” are the latest industry buzzwords. So what is a virtual app?

virtual appIn a traditional IT environment, applications are installed on each machine. When an application is installed, it creates multiple files on the client device. While application files are stored in the application folder, DLL files go to the Windows folder, and system files are saved in the registry database.  As more applications are installed, DLL files get overwritten, and another program might uninstall shared files. These issues result in an application conflict and mess up the operating system as well. In a large enterprise of tens of thousands of nodes, application conflict is a big issue. When you deploy a VDI, there are additional problems. You need to install all the applications into your base image or install each app on-demand, which again takes time.  That’s where virtual apps come to the rescue.

Virtual App

Virtual apps are applications that are optimized to run in a virtual environment. Simply put, a virtual app simply runs on a computer without being installed on it. Remote apps are a popular virtual app delivery solution wherein the virtual applications installed on a server are delivered to users’ devices. These applications are not installed on the user’s device; instead, software called a client is installed on the device that connects to the server, and the application is presented as screenshots sent to the device.

There are several other virtualization solutions, such as portable apps, wherein all the DLL and registry files are encapsulated in an EXE file, enabling you to copy or move the application as a single file. You don’t have to install portable apps on a computer but can still use them on a USB stick, laptop, or any network. Application streaming is another process whereby the application’s resources are carried to the endpoint at the time of its execution. VMware ThinApp is an example of an agentless application virtualization solution, while Microsoft App-V represents an agent-based virtual app solution. Parallels Remote Application Server, Citrix, and VMware are the leading providers of application virtualization solutions in the market.

Challenges with application virtualization solutions

While a virtual app optimizes a company’s resources and improves its efficiency, there are specific challenges as well. Firstly, implementation of application virtualization solutions such as Citrix Virtual Apps (formerly Citrix XenApp), RDS, or VMware Horizon is a complicated task. For instance, Citrix VDI solutions require you to hire a certified professional to install the network. Moreover, business networks need to be dynamically realigned with business expansion, and several components need proper configuration. Printing is also a challenge in a VDI environment. Secondly, the BYOD revolution has brought an array of smartphone models into company networks, but publishing apps to remote mobile devices is a challenge. Thirdly, heterogeneous networks introduce security challenges. Fourthly, businesses need to comply with government regulations concerning data management solutions. Most importantly, application virtualization solutions are expensive.
