April 5, 2026

Serverless Workflow Orchestration

Visual workflows coordinating Lambda/services.

State Machine Types

Standard Workflows:
- Durable execution (1 year)
- $0.025/1K state transitions

Express Workflows:
- High volume (4M/min)
- $1.00/1M state transitions
- Short duration (5min max)

Patterns:
Choice -> Parallel -> Map -> Wait
Catch/Fallback error handling
Retry policies (exponential backoff)

Integration

200+ AWS service integrations
HTTP endpoints
Callback patterns (async)
CloudMap service discovery
