What is Integration Platform as a Service (iPaaS)?

An Integration Platform-as-a-Service (iPaaS) is a cloud-based integration solution for connecting any combination of on-premises and cloud-based applications and data across any number of organizations. It provides the tools needed to create, govern, and secure all your cloud-to-cloud, cloud-to-ground, and ground-to-cloud integrations to make real-time connectivity simple, seamless, scalable, and secure.

iPaaS platform capabilities: simplify enterprise integration, propel innovation

Simplify cloud and on-premises connections with one iPaaS platform

Simplify current and future integrations by creating standardized virtual models for the data used across your entire architecture 

Accelerate project delivery with low-code iPaaS

Easily build integrations that deliver innovative new experiences to market nearly 10X faster than without an iPaaS

Enable self-service integration for citizen integrators

Reduce the risks of shadow IT by enabling citizen integrators to build new integrations with less involvement from IT 

Scale gracefully across the hybrid integration platform

Create repeatable integration patterns to eliminate the hassle and complexity of starting from scratch for each new integration.

Common iPaaS use cases

Application integration: connect SaaS, custom, and on-premises apps without custom code.

API-led integration: combine iPaaS with API management to publish, secure, and reuse integrations as APIs.

B2B and partner integration: onboard trading partners and exchange EDI and API traffic through a single iPaaS platform.

Cloud migration and AWS integration: integrate AWS workloads with on-premises systems during and after cloud migration.

Data integration and synchronization: keep customer, product, and order data consistent across systems in real time. 

iPaaS vs. ESB and traditional middleware

Where ESB, ETL, and custom middleware require deep specialist skills and long delivery cycles, an iPaaS platform delivers the same connectivity in the cloud — with low-code tooling, built-in governance, and elastic scale — so business and IT teams can deliver integrations together.

Frequently asked questions about iPaaS

What does iPaaS stand for?

iPaaS stands for Integration Platform as a Service — a cloud-based platform for building, deploying, and managing integrations between applications, APIs, and data sources.

The iPaaS definition is straightforward: a cloud service that provides the tools to create, govern, and secure integrations across cloud and on-premises systems, without installing or maintaining integration middleware yourself.

API management focuses on publishing, securing, and monitoring APIs. iPaaS focuses on connecting applications and data. A modern hybrid integration platform like Axway Amplify combines both so you can build an integration once and expose it as a managed API.

Typical iPaaS use cases include application integration, B2B and EDI integration, cloud migration (including AWS, Azure, and GCP), data synchronization, and API-led automation across hybrid environments.

iPaaS is used by enterprise IT teams, integration developers, and citizen integrators in lines of business who need to connect SaaS apps, on-premises systems, and partner networks quickly and securely.

Evaluate iPaaS vendors on hybrid (cloud and on-premises) support, API management depth, B2B and EDI capabilities, governance and security, low-code experience, and pricing. Axway's iPaaS solution is built into the Amplify hybrid integration platform.
