# Connecting to AWS S3 Storage

Amazon S3 is AWS’s object storage solution for the cloud. Object storage is optimized for storing massive amounts of unstructured data.

## AWS S3 Permissions

Connect [Publisher](https://github.com/DNAstack/dnastack-product-docs/blob/main/docs/publisher/data-sources/connectors/broken-reference/README.md) to [AWS S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html) storage to access and share your data. The configuration process involves setting up connection details and choosing data update preferences.

## Prerequisites

Before starting, gather these required details:

* S3 bucket name
* Bucket region
* AWS Access Key ID
* AWS Secret Access Key

## Configuration Process

### Initial Setup

From the Publisher interface, select "Data Sources" in the navigation bar and click the "Connect Data Source" button. Choose "AWS S3 Object Store" from the available connectors.

### Connection Details

Enter your AWS S3 configuration:

* Storage Bucket name
* Access Key ID (or "Anonymous" for public access)
* Secret Access Key (or "Anonymous" for public access)
* Bucket Region (e.g., us-east-1)

{% hint style="info" %}
Note: For anonymous access to public buckets, use "Anonymous" for both the Access Key ID and Secret Access Key.
{% endhint %}

{% hint style="info" %}
For more information about creating AWS access keys, consult [AWS documentation](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html#Using_CreateAccessKey).
{% endhint %}

### Data Update Configuration

Configure how Publisher monitors your S3 bucket for changes:

* **S3 Event Notifications with SQS**:
  * Create a dedicated [SQS](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/welcome.html) queue for S3 bucket notifications
  * If not already done, [grant Amazon S3 permissions](https://docs.aws.amazon.com/AmazonS3/latest/userguide/grant-destinations-permissions-to-s3.html#grant-sns-sqs-permission-for-s3) to publish messages to SQS.
  * Provide the SQS queue name
* **Scheduled Updates**:
  * Choose an update interval (30 seconds to daily)
  * Updates can be configured later if needed

## Finalizing Setup

Provide a descriptive name for your data source. After connection, you have the option to create and share a collection from this data source.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.omics.ai/products/publisher/data-sources/connectors/connecting-to-aws-s3-storage.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
