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
editThe 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.
