Integration platform as a service (iPaaS) is a suite of cloud services enabling customers to develop, execute and govern integration flows between disparate applications.[2] Under the cloud-based iPaaS integration model, customers drive the development and deployment of integrations without installing or managing any hardware or middleware.[1] The iPaaS model allows businesses to achieve integration without big investment into skills or licensed middleware software.[citation needed] iPaaS used to be regarded primarily as an integration tool for cloud-based software applications, used mainly by small to mid-sized business. Over time, a hybrid type of iPaaS?Hybrid-IT iPaaS?that connects cloud to on-premises, is becoming increasingly popular. Additionally, large enterprises are exploring new ways of integrating iPaaS into their existing IT infrastructures.

Cloud integration was basically created to break down the data silos, improve connectivity and optimize the business process. Cloud integration has increased its popularity as the usage of Software as a Service solutions is growing day by day.
