Determine your playbook flow in

The order in which you arrange the blocks and lines in your playbook determine the playbook flow.

Process playbook blocks serially

Serial processing means playbook blocks are performed in the order they are arranged.

In this example, the blocks perform as described:

1. A geolocate ip is performed on a source IP address.
2. When the geolocate ip action is finished, a lookup ip performs.

Use serial processing when there must be a specific order to the operations, such as when a downstream block depends on the results from an upstream block.

Processing playbook blocks in parallel

You can also wire blocks to process in parallel, as shown in the following example.

In this case, the geolocate ip and lookup ip actions perform simultaneously, and either action can finish first. You can wire blocks in this manner when you have no dependencies on the completion of either block, or if there are no dependencies between the blocks themselves.
