How step transitions are counted
Each step type contributes differently to the total transition count. The following examples show how transitions are counted 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 transitions
Foreach 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 transitions
Choice 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
Service suspension protection
Alibaba Cloud provides the extended suspension-free benefit. When a pay-as-you-go resource is overdue, you can continue to use cloud services for a certain amount or duration. Normal fees apply during the extended period. For more information, see Extended Suspension-Free Benefit.
