Application service provider
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
    
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

An ASP hosts software applications, which its customers access over the Web instead of running them on their own computers.
