“iPaaS- integration platform as a service”, gained its popularity when the business user became aware of controlling and sharing data across a number of SaaS applications.

Previously, it was ESB (Enterprise Bus Service) that used standards-based services to satisfy the need of integrating applications.

But, with the rise of enterprise integration middleware, businesses move to implement open source and cloud-based services.

However, the ESB’s do not address the combination of open source-cloud based technology owing to its limitations.

Hence, iPaaS comes in to picture to address the combination and integration of
open source & cloud-services.
