In business-to-business (B2B) integration, IaaS allows partners to develop, maintain, and manage custom integrations for diverse systems and applications in the cloud. In this way, the enterprise can more effectively pursue process innovations without the need to constantly modify and maintain diverse and often incompatible application programs.
IaaS vendors will typically provide infrastructure, such as servers, along with middleware. Vendors will also commonly supply tools for customers to build, test, deploy, and manage cloud applications. Payment is typically available in the form of a ‘pay as you go’ model, so users can readily scale their environments up or down. Most IaaS vendors will also share a multi-tenant setup.
Customers of an IaaS service will typically interact with their data via a web-based interface, which interconnects backend data, systems, and files with other data, applications and systems in other locations. IaaS also removes system and data interdependencies through this process.
