Application Virtualization Overview

Application Virtualization Overview

• Application virtualization runs applications independently from the host OS, isolating the application's data from the host.
• It's distinct from workstation or server virtualization; it doesn't create a separate virtual hardware environment.
• Instead, it abstracts the application's file system and Registry, allowing multiple versions of the same software to run concurrently.
• This avoids conflicts between applications and minimizes the risk of corrupted host system files.

Benefits of Application Virtualization

• Enables running virtualized applications like standard applications.
• Eliminates a program's footprint in the host's Registry and file system.
• Prevents conflicts with other applications and avoids Registry corruption.
• Supports easy installation, removal, and management of applications.

Types of Application Virtualization Products

• VMware ThinApp: A key component of VMware's Horizon virtual desktop products. Isolates applications from the OS for streamlined deployment and mobility.
• Microsoft App-V: Virtualizes all application aspects, featuring streaming deployment and pre-packaged virtual applications. Requires Microsoft Active Directory, suited for larger Windows networks.
• Altiris Software Virtualization Solution (SVS): Suitable for stand-alone desktops. Does not fully virtualize application functions like system and COM calls, but virtualizes core application objects like the Registry and file system, enough for most end-user needs.

Role in VDI Environments

• Application virtualization plays a crucial role in VDI environments.
• It efficiently delivers and manages applications to various user and desktop setups.
