Application service provider

From Wikipedia, the free encyclopedia

An application service provider (ASP) is a business providing application software generally through the Web.[1] ASPs that specialize in a particular application (such as a medical billing program) may be referred to as providing software as a service.

The ASP model

[edit]

The application software resides on the vendor's system and is accessed by users through a communication protocol. Alternatively, the vendor may provide special purpose client software. Client software may interface with these systems through an application programming interface.

ASP characteristics include:

  • ASP hosts the application[2]
  • ASP owns, operates and maintains the servers that support the application[2]
  • ASP delivers the application to customers via the Internet[2] or a thin client
  • ASP may bill on a per-use basis (on-demand outsourcing), a monthly/annual fee, or a per-labor hour basis

The advantages to this approach include:

  • Application costs are scaled over multiple customers[2]
  • ASP may provide more application experience than the customer's staff[2]
  • ASP may provide application customization for the customer[2]
  • Application's version is likely to be kept up to date
  • Experts manage the application for performance[2]
  • Experts research the application for new features[2]

The disadvantages include:

  • The customer must rely on the ASP for a critical business function, including security and performance[2]
  • The customer may have to accept the application as provided
  • The customer may have to adapt to possible application changes
  • Integration with other applications may be problematic
