Because of the extensive development and integration requirements, hosting providers today offer a limited variety of hosted applications. As a result, independent software vendors have little incentive to create hosted applications that they cannot sell, and customers suffer from limited application choices.
In response to this, Application Provisioning Standard (APS) was developed. It is an open format of packaging and managing web applications that will make it easier for the whole hosting industry to take advantage of the expanding software-as-a-service (SaaS) market.
By defining such open format, APS increases business opportunities for the entire hosting ecosystem bringing together application vendors and hosting service providers. By implementing APS, application vendors get access to a vast sales and marketing channel of APS-enabled hosting providers. In turn, hosting services providers, by implementing APS, gain access to a great variety of APS applications.
APS implemented by a hosting services provider means that the provider uses such software that processes APS applications in full compliance with the rules defined by the standard. The Controller, to which this document is devoted, is exactly that part of the software which is responsible for such processing.
