At work, we invoke an async Lambda function to make a lot of concurrent requests to different APIs for one input. In short: a batch.

Lambda passes the data to another component on AWS to be processed.

The input sources for data range from APIs calls on Lambda, data from partners, data from legacy components, etc. So we split our data sourcing/fetching and data processing. They all flow into the same funnel (component) to be processed.
