Key points
- •Task: does the actual work, often a Lambda invocation or a direct AWS service SDK call
- •Choice: native conditional branching based on the state's input
- •Parallel: runs multiple independent branches simultaneously, waits for all to finish
- •Map: runs the same steps once per item in an input array, concurrently or sequentially
