## Getting Started

Connect your Amazon S3 bucket to Aampe to ingest event data for personalization.

## Bucket Ownership Options

Aampe supports two approaches for S3 data ingestion:

| Option                                                                                                 | Best For                                                                           | Setup Time   |
| ------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------- | ------------ |
| [Customer-Owned Bucket](/developer-guide/data-ingest/data-sources/cloud-storage-aws-s3-customer-owned) | Enterprise customers who need full control over data storage and security policies | \~1 hour     |
| [Aampe-Owned Bucket](/developer-guide/data-ingest/data-sources/cloud-storage-aws-s3-aampe-owned)       | Customers who prefer a simpler setup without managing bucket permissions           | \~30 minutes |

## Which Option Should I Choose?

**Choose Customer-Owned Bucket if you:**

* Have existing data pipelines writing to S3
* Need to comply with data residency requirements
* Want full control over bucket lifecycle policies, encryption, and access logs
* Prefer to manage data in your own AWS account

**Choose Aampe-Owned Bucket if you:**

* Want the fastest setup experience
* Don't have existing S3 infrastructure
* Prefer Aampe to manage the storage infrastructure

## Data Format

Regardless of which option you choose, your event data should follow the [Aampe Data Model](/developer-guide/data-ingest/data-model). Supported file formats include:

* JSON or Newline Delimited JSON (ndJSON) - *Preferred*
* CSV
* Parquet
