In practice, the main differences between developing for developing for the Nicman Vault service and developing for Amazon S3 are:

• As detailed in this document, the Vault service supports the great majority of but not the entire Amazon S3 API.

• Also as detailed in this document, the Vault service supports a small number of extensions to the Amazon S3 API.

• Vault client applications must use the Nicman Vault service endpoint rather than the Amazon S3 service endpoint.

• You will need to use either the Vault Management Console or the Nicman Vault Administration API to create and manage service user accounts.
