Comparing an iPaaS with point-to-point integrations
Compare direct integrations with an iPaaS using connection growth, ownership, change control and ongoing operating work.
Choose between an iPaaS and point-to-point integrations by comparing the connections you expect to operate, not just the effort of building the first one. A direct link can suit one stable exchange with a clear owner.
An iPaaS may help when teams need to reuse connections, manage changes across several flows and see those flows in one place. Either route still depends on the connected applications and needs a way to handle uncertain outcomes.
Map the connections you need
A point-to-point integration links a producer and consumer directly, through an API or another agreed interface. It might use custom code or an application's own integration feature.
An iPaaS provides a managed place to build and operate integration flows, commonly using connectors and transformation tools. Those flows may still call application APIs.
List the applications, the direction of each exchange and the owner of each endpoint. Count requested flows and credible planned changes, rather than assuming every possible pair of applications will need a connection.
Direct connection
- First implementation
- Build or configure the specific exchange
- Another consumer
- Assess whether to reuse the existing integration or add a link
- Change control
- Track dependencies where each link is owned
- Troubleshooting
- Gather evidence from the applications and integration
- Ongoing commitment
- Maintain the integration, its access and any required hosting
iPaaS route
- First implementation
- Set up the platform connection and build the flow
- Another consumer
- Assess whether a connection and mapping can be reused
- Change control
- Track platform flows and their external dependencies
- Troubleshooting
- Use platform run records alongside application records
- Ongoing commitment
- Maintain platform entitlement, flows, connections and access
Compare ongoing work
Take a representative change: a customer record moves from sales to billing, then must also reach a support application.
For a direct route, identify where the record is transformed, where credentials are held and who updates the links if the sales interface changes.
For a platform route, check that the connector exposes the required operations and fields, whether mapping can be reused and how each flow is deployed.
Include access reviews, monitoring, incident response, environment separation, application changes and staff handover. Name the team that will maintain each option. Compare costs over the same expected period and workload using current terms; a subscription price and an initial development estimate do not cover the same work.
Platform run records may help locate a failed flow. They cannot alone establish whether a destination completed a write before its response was lost. Both routes need a way to reconcile that outcome before repeating the action.
Make the choice per flow
Keep a direct integration when its purpose is narrow, its interface can be maintained and a team owns its monitoring and changes. Document the owner, destination reference and recovery path so the link remains visible.
Consider an iPaaS when several flows need similar application access or transformations and its exact operations meet those requirements. Check the connector, entitlement, network path and operational controls before relying on the platform.
A migration need not include every existing link. A well-owned direct connection can stay in place while new or frequently changing flows use a platform. Revisit a link when its application interface changes or its owner can no longer support it.
