Middleware License Cost at 72% deployment coverage this cycle: a worked example

This worked example runs the middleware license cost numbers for a tougher week than the baseline: 72% deployment coverage this cycle instead of the typical 100%. Estimate annual middleware or iPaaS license cost by combining connector count, per-connector pricing, coverage scope, and fixed platform fees. Use this to compare integration platform pricing models.

The inputs for this scenario

  • Active connectors or endpoints: 8 connectors (held at the documented default)
  • Annual cost per connector: 5,000 $ / connector (held at the documented default)
  • Deployment coverage this cycle: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed annual platform fee: 12,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable connector cost = active connectors x annual cost per connector x (deployment coverage / 100).
  • Total annual middleware cost works out to 40,800 $ at these inputs, and this is the headline figure for the scenario.
  • Effective cost per connector works out to 5,100 $ / piece at these inputs.
  • Variable connector cost works out to 28,800 $ at these inputs.
  • Fixed annual platform fee works out to 12,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where deployment coverage this cycle sits at 100% and the headline result is 52,000 $, this scenario comes in 21.54% below the baseline at 40,800 $.
  • Use it during vendor selection, annual renewal budgeting, or when phasing connectors in over a deployment so you only pay for what is live this cycle. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total annual middleware cost: 40,800 $ (headline result)
  • Effective cost per connector: 5,100 $ / piece
  • Variable connector cost: 28,800 $
  • Fixed annual platform fee: 12,000 $
