How can I use my own Amazon AWS S3 bucket storage with CloudApp?

For customers on our CloudApp for Business and Team, you have the ability to use your own Custom AWS buckets to store your team's CloudApp Drops.

To set this up you need an S3 Bucket and a set of AWS keys with read/write permission for it. Below are instructions on how to configure this for CloudApp.

  1. Create an S3 Bucket in your AWS account as described here.
  2. Once the bucket is created, go to the bucket’s Permissions Section and click on CORS configuration.
  3. This is the minimum CORS policy you need:


    If you are also using a custom domain, you will need to include an additional AllowedOrigin line. For example:
    <AllowedOrigin>my.custom.domain</AllowedOrigin>.

  4. With the bucket created we need to generate API keys that can access the bucket. We will do this with AWS IAM.

    The first step is to create the policy. Navigate to the Policy section of the IAM site and click Create Policy:
    Here is the preferred JSON for the policy:


    On the next screen give the policy a name and optional description then click Create Policy

  5. With the policy created, go to the group section and click Create Group Next, set the group name and click next step
    On the next screen, use the search to find your policy and select the checkbox next to it, and then click the Next Step button
    And create the group

  6. Now we create a user and add them to this group. Go to the Users section and select Add User
    Now give the user a name and choose the programmatic access option and then click the Next: Permissions button
    Select your group from the list and click next
    Skip past the next screen by hitting Next
    Make sure everything looks right and then click Create User
    Download or copy your keys

  7. Now with your bucket and keys created, we need to enter them in your CloudApp account.

    Go to Settings > Storage Resources > Hit Submit for S3 and enter in your details.
