Application service providers (ASPs) are a new type of service providers that make the whole spectrum from low-end applications like e-mail systems to high-end applications like enterprise resource planning (ERP) management systems available to customers over the Internet through browser-based user interfaces (application hosting). This relieves a customer from installing and managing the applications himself in his own data center. Instead, the customer pays a fee for accessing the application over the Internet. However, as soon as a customer uses several applications hosted by different ASPs, a management burden arises for the customer as well as an application integration problem, since the applications are hosted individually by several ASPs without any coordination or data exchange between them. The arising integration (aggregation) problems are discussed in this chapter. An ASP aggregation architecture is defined based on B2B integration servers that address these problems by supporting the seamless access and seamless integration of all hosted applications hiding the differences between the ASPs.
