CloudFlow uses pay-as-you-go billing. You pay only for what you use.
Billing
You are charged based on the number of step transitions in your flow execution.
The free quota and unit price listed below are for reference only. Actual prices and quotas for commercial use prevail.
| Category | Description |
|---|---|
| Billing method | Pay-as-you-go |
| Billing unit | Step transitions |
| Free quota | 5,000 free step transitions per month, per Alibaba Cloud account (including RAM users within the account) |
| Unit price | USD 0.25 per 10,000 step transitions |
How step transitions are counted
Each step type contributes to the total transition count differently. The following examples show how to calculate transitions for common patterns.
Parallel step
A parallel step with three branches, each containing one task step, produces 4 step transitions: 1 parallel step transition + 3 task step transitions.
parallel (1 transition)
├── task (1 transition)
├── task (1 transition)
└── task (1 transition)
Total: 4 step transitionsForeach step
A foreach step that loops a single task step four times produces 5 step transitions: 1 foreach step transition + 4 task step transitions.
foreach (1 transition)
└── task x 4 iterations (4 transitions)
Total: 5 step transitionsChoice step
A choice step with three branches, each containing one task step, produces 2 step transitions when one branch runs: 1 choice step transition + 1 task step transition.
choice (1 transition)
├── task (1 transition) ← runs
├── task
└── task
Total: 2 step transitions
