# APP Flow
AWS AppFlow is a service that helps you move data automatically between different applications without writing code. Think of it as a bridge that connects apps like Salesforce, Slack, Google Analytics, or your own systems to AWS services like S3 or Redshift.
Why it exists:
* Companies often have data spread across multiple apps. Manually moving it is slow and error-prone.
* AppFlow automates this process, keeping your data updated and synchronized.
* It can also transform data as it moves, like changing formats, filtering, or mapping fields.
**Simple use case:**
* You want all your Salesforce customer data to go into Amazon S3 every night.
* Instead of exporting manually, AppFlow does it automatically.
In short: AWS AppFlow = automatic, no-code data transfer between apps and AWS, with optional data transformation.
