iPaaS
A hosted platform for building and running integrations between systems. Buys you speed and observability; costs you a dependency and a bill that scales with volume.
Also called: Integration Platform as a Service
What it is
An integration platform as a service is hosted middleware: you build the connection between two systems in its interface, and it runs, retries and logs that connection for you. Workato, Tray, Boomi and Make occupy this space, as does Zapier at the simpler end.
The real choice
Native integration: cheapest and least flexible. Use it when it covers the case — a native sync you do not maintain beats a clever one you do.
iPaaS: use when the logic exceeds what native offers but does not warrant engineering time, or when you need retries and monitoring you would otherwise build.
Custom code: use when volume, latency or logic genuinely require it, and you have someone to own it in two years.
What people underestimate
An iPaaS makes integrations easy to create, which means you get more of them, which means the map of what talks to what becomes hard to hold in your head. The platform is not the risk; the sprawl it enables is. Name recipes consistently, record which are business-critical, and review the list on a cadence.
Ask before buying
What happens when a step fails — retry, alert, or silence? Who is notified? How would you know the sync stopped, other than someone noticing missing records? Silent failure is the defining integration risk and the answer should not be discovered during an incident.
RELATED TERMS
Integration Layer
The connections moving data between systems, and the rules governing direction, timing and conflict.
Data Orchestration
Coordinating how data moves and transforms across systems so a multi-tool stack behaves like a single one.
Data Governance
The rules determining who may change what, how changes are reviewed, and how they are recorded. The control that stops a designed system from drifting back to whatever it was before.
Single Source of Truth (SSOT)
The declared authority for a given piece of data — the system whose value wins when two systems disagree. Correctly applied it is decided per field, not per system.
COMMON QUESTIONS
- Is Zapier an iPaaS?
- At the light end, yes. The distinction that matters in practice is error handling and governance: enterprise-grade platforms give retries, versioning and audit trails that lighter tools do not.
- iPaaS or native integration?
- Native, wherever it genuinely covers the requirement. It is cheaper, better supported and one less vendor. Reach for an iPaaS when the transformation or conditional logic exceeds what native offers.
- What is the main hidden cost?
- Task or operation volume pricing, and sprawl. Both scale quietly — the bill grows with business volume, and the number of recipes grows with how easy they are to make.
