To add an AWS public cloud account in VMware Cloud services, you need your AWS security credentials (Access Key ID and Secret Access Key) and your S3 bucket name. You also need to set billing access and the correct permissions for IAM users in your account.

Amazon recommends specific best practices for setting up IAM users and security credentials. For more information on these recommendations, see https://media.amazonwebservices.com/AWS_Cloud_Best_Practices.pdf.
