Configuring Amazon S3 work with MongoDB Realm through the Cosync Storage module is relatively easy. The developer must create an Amazon S3 user with some access keys and a storage bucket. In order to set up the MongoDB Realm Application through the Cosync Portal, the developer will need to gather the following information.

• AWS user access key
• AWS user secret access key
• AWS S3 bucket name
• AWS bucket region code

In the following section we show the developer how to create and Amazon S3 user, along with a set of API keys, as well as create an S3 bucket, which will hold all of the assets uploaded from from a MongoDB Realm application through the Cosync Storage module.
