Application Virtualization – Definition & Detailed Explanation – Virtual Computer Glossary Terms

I. What is Application Virtualization?

Application virtualization is a technology that allows applications to run in isolated environments, separate from the underlying operating system. This means that applications can be deployed and managed independently of the hardware and software configurations of the host system. By virtualizing applications, organizations can streamline software deployment, reduce compatibility issues, and improve system performance.

II. How does Application Virtualization work?

Application virtualization works by encapsulating an application and its dependencies into a virtual package. This package contains all the necessary files, settings, and registry entries required for the application to run. When the application is launched, the virtualization layer intercepts calls to the operating system and redirects them to the virtual environment, isolating the application from the host system.

III. What are the benefits of Application Virtualization?

Some of the key benefits of application virtualization include:

1. Simplified deployment: Virtualized applications can be deployed quickly and easily without the need for complex installation processes.

2. Improved compatibility: Virtualized applications can run on any system regardless of the underlying hardware or software configurations.

3. Reduced conflicts: By isolating applications from the host system, application virtualization helps to prevent conflicts between different software programs.

4. Enhanced security: Virtualized applications are sandboxed, making it more difficult for malware to infect the host system.

5. Increased flexibility: Application virtualization allows organizations to easily scale their software deployments up or down as needed.

IV. What are the common use cases for Application Virtualization?

Some common use cases for application virtualization include:

1. Legacy application support: Organizations can use application virtualization to run older applications on modern operating systems.

2. Software testing and development: Application virtualization allows developers to test software in isolated environments without affecting their main system.

3. Remote access: Virtualized applications can be accessed remotely, enabling users to work from anywhere with an internet connection.

4. BYOD (Bring Your Own Device): Application virtualization enables employees to access company software on their personal devices without compromising security.

V. What are the challenges of implementing Application Virtualization?

While application virtualization offers many benefits, there are also some challenges to consider:

1. Performance overhead: Running applications in a virtualized environment can introduce some performance overhead, especially for resource-intensive applications.

2. Licensing issues: Some software vendors may have restrictions on virtualizing their applications, which can complicate licensing agreements.

3. Compatibility issues: Not all applications are suitable for virtualization, and some may not function properly in a virtual environment.

4. Management complexity: Managing a large number of virtualized applications can be complex and time-consuming, requiring specialized tools and expertise.

VI. What are some popular Application Virtualization software options?

Some popular application virtualization software options include:

1. VMware ThinApp: VMware ThinApp is a popular application virtualization solution that allows organizations to package and deploy applications in a virtualized environment.

2. Microsoft App-V: Microsoft App-V is a component of the Microsoft Desktop Optimization Pack (MDOP) that enables organizations to deploy and manage virtualized applications.

3. Citrix XenApp: Citrix XenApp is a virtual application delivery solution that allows users to access applications from any device, anywhere.

4. Parallels Remote Application Server: Parallels Remote Application Server is a comprehensive virtual application and desktop delivery solution that supports a wide range of platforms and devices.

Overall, application virtualization is a powerful technology that can help organizations streamline software deployment, improve compatibility, and enhance system performance. By understanding the benefits, challenges, and popular software options, organizations can make informed decisions about implementing application virtualization in their IT environments.
