Application Virtualization

Application Development and Maintenance

Application virtualization is an umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, although it is still executed as if it is. The application is fooled at runtime into believing that it is directly interfacing with the original operating system and all the resources managed by it, when in reality it is not. Application virtualization differs from platform virtualization in that in the latter case, the whole operating system is virtualized rather than only specific applications.

How can we help ?

AAPTAA has a pool of highly experienced and certified Virtualization Engineers who can assist you in every aspect of this Virtualization Process.

Benefits of Application Virtualization

  • Validation – Because applications are hosted on servers, there is no need to validate workstations. Server validations are easier to manage and control.
  • Complex Installations – Software applications that require specific client software or special components not compatible with other applications are moved from the client to the server, thereby avoiding installation conflicts.
  • Network bandwidth of applications – Applications that require a large amount of bandwidth, which are inefficient over a WAN or remote connection, can be easily maintained.
  • Greater flexibility in positioning of applications across servers, enabling smaller maintenance windows, easier disaster recovery processes, more dependable service levels.
  • Central Administration and Maintenance – Centrally managed application patches and enhancements on servers instead of workstations make administration easier.
  • Optimal License Usage – More efficient use of concurrent licensing.
  • Allows applications to run in environments that do not suit the native application.
  • May protect the operating system and other applications from poorly written or buggy code.
  • Run incompatible applications side-by-side, at the same time and with minimal regression testing against one another.
  • Maintain a standard configuration in the underlying operating system across multiple computers in an organization, regardless of the applications being used, thereby keeping costs down.
  • Maintain a standard configuration in the underlying operating system across multiple computers in an organization, regardless of the applications being used, thereby keeping costs down.
  • Implement the security principle of least privilege by removing the requirement for end-users to have Administrator privileges in order to run poorly written applications.
  • Simplified operating system migrations.
  • Accelerated application deployment, through on-demand application streaming.
  • Improved security, by isolating applications from the operating system.
  • Enterprises can easily track license usage. Application usage history can then be used to save on license costs.
  • Fast application provisioning to the desktop based upon user's roaming profile.

Limitations of application virtualization

  • Not all software can be virtualized. Some examples include applications that require a device driver and 16-bit applications that need to run in shared memory space.
  • Some types of software such as anti-virus packages and application that require heavy OS integration are difficult to virtualize.
