# Configuring S3 Client Interfaces

The VAST Cluster S3 service supports client connection using any S3 client that supports HTTP or HTTPS to call the REST API.

VAST Data-specific guidelines are available for using the [S3cmd command line tool](/docs-5-3/docs/s3cmd) or the [Boto 3 SDK for Python](/docs-5-3/docs/boto3-client).S3cmd

In general, to get started with any client interface, you will need to configure the following:

- The endpoint for the VAST Cluster S3 service. Specify the DNS hostname for the cluster virtual IP pool (see [Configuring Network Access](/docs-5-3/docs/en/configuring-network-access))Configuring Network Access.
- The connection type. VAST Cluster can listen to S3 service requests on HTTP or on HTTPS. When configuring the client to connect over HTTPS, see [installing an SSL certificate](/docs-5-3/docs/en/enabling-an-https-connection).Enabling an HTTPS Connection

> [!NOTE]
> Note
> 
> It is possible to disable S3 HTTP and/or HTTPS connection. See [S3 Connection Settings](/docs-5-3/docs/en/s3-connection-settings).S3 Connection Settings
- Credentials. Specify an access key pair generated for you via VMS.
- Signature type for authenticated requests. VAST Cluster supports AWS signature version 2 and AWS signature version 4.
