Middleware
What is middleware?
Middleware is software that sits between your systems and translates, checks and passes on data, so applications can work together.
Where a direct integration connects two systems, middleware connects many at once through one layer. That layer translates formats, checks the data, records what was exchanged and catches errors when a system is briefly unavailable. We build that kind of integration layer under connecting systems with middleware. Check whether middleware suits your systems with our integration chooser.
An iPaaS (integration platform as a service) is middleware in the cloud. Light options such as Zapier and Make are fine for single steps; with lots of data, exceptions or business-critical processes, an integration layer you fully own pays off.
