Application virtualization is the process of separating the installation of an application from the client computer. The application is installed away from the computer on which it can be accessed. Application virtualization is of two types – remote and streaming. Virtualized applications can run on a server, and end users can interact with them via remote display protocol. Remote applications can be controlled with complete integration to the client’s desktop. Owing to the seamless windows technology, virtualized applications behave like any other application. For the remote application to functions incessantly, a constant network connection has to be maintained.
Importance of Application Virtualization Software
The technology of application virtualization is largely adopted by businesses to ensure greater portability and the ease of maintenance. Programs can be deployed easily across several versions of Windows to ensure higher portability. Also, clients can manage the systems of their employees and ensure that important applications run seamlessly.
In the case of application virtualization, program executables, dependencies and configuration files are abstracted from the operating system. Within the unique environment of each virtualized application, there are registry entries, supporting executables, libraries and all other things required for running the application.
As every application runs within its own environment, it’s possible to run several versions of a program at the same time. It is also possible to run an application on a new operating system than the one it was designed to run originally. Virtualized applications can use old security configurations and DLLs to run smoothly on Vista even if they were originally running on XP or Windows 2000.
With slight changes in the program’s code, a virtualized application can run remotely on Vista. Another benefit of application virtualization is that it treats heterogeneous environments in a homogenous manner.
Further, those applications which rely on custom libraries or drivers can be installed easily. With this, the task of deploying patches and upgrades also becomes smooth and effortless. Virtualized applications share a single executable file, and make it possible to deploy applications for contractual workers, who are working on a particular task for certain number of days.
Factors to Consider When Buying Application Virtualization Software
To select the best application technology for specific application requirements, buyers need to follow these important steps:
- As the first step, you need to determine if application virtualization is apt for a given situation
- Then, look for the design of the workflow to recognize if it runs on a Windows server or on a client computer
- Next, the selection has to be done between server hardware and server software virtualization. It is important to determine those products, which can provide the most important platform for application virtualization.
- Based on client connectivity and network requirement of client computers, customers need to narrow down the virtualization options. Uninterrupted network support is important for client computers to access virtualized applications.
- Determining the workload location is another significant step. The location where workload runs can be centralized or decentralized. If it’s centralized, you need to select the option of desktop or session virtualization. In the case of decentralized workload location, application virtualization and desktop virtualization are the best choices.
- In case of desktop or session virtualization, the virtual desktop infrastructure technology is used, which hosts the desktop operating system on the centralized server of a data center.
- For session virtualization, Windows server 2008 remote desktop services are used.
With the right selection of application virtualization software, enterprises can enjoy scalability and flexibility of applications at the same time. Gone are those days when end users where compelled to do a specific task from a particular location. With the workforce becoming more mobile and using new devices for work, there is an increased need of application virtualization software.
Managing and delivering services to end users with the use of with traditional computers can be a time consuming and costly affair. Application virtualization solutions require Linux desktops or Windows in the cloud or on premise to save time and money.
