Integration platform as a service (iPaaS) is a cloud service that provides a platform to support application, data and process integration projects, usually involving a combination of cloud-based applications and data sources, APIs and on-premises systems.

With a growing number of cloud based applications and services, many organizations have shifted from buying applications from a single vendor, and instead have employed a best of “breed approach”, mixing and matching vendors in order to obtain the best products for specific areas of business. This leads to a “spaghetti architecture” as these multiple applications need to talk to each other seamlessly thus increasing the complexity of implementing this custom integration.
