Definition
Middleware can transform data, retry failures, apply rules, and isolate systems from each other’s technical details. It is often the connective tissue behind a more resilient integration landscape.
Why it matters
It can prevent direct point-to-point connections from becoming difficult to change or troubleshoot.
Business example
A middleware layer validates customer records and retries a temporary accounting-system outage instead of losing the update.
When to use it
Use it when multiple systems need transformation, monitoring, routing, or reliable error handling.
When not to use it
Do not add it to a simple one-way integration when the extra layer creates more operational burden than value.
How Automathing approaches it
We use middleware where it reduces coupling and improves operability, not as an extra layer by default.
