Integration platform as a service (iPaaS) is a set of cloud-based tools enabling deployment, management, and governance to connect software applications and services across different environments.
iPaaS is most often used by large business-to-business (B2B) organizations that need to integrate on-premises applications and data with cloud applications and data. As a cloud-based toolset, iPaaS is scalable to meet the increased data volume from multiple environments. An iPaaS should support real-time integration with the goal of minimum disruption.
Today, there are legacy iPaaS providers which are older, existing integration companies that have modified their tools to work with cloud services. Modern solutions are ones that were born within the cloud age.
