DigitalOcean is a cloud provider that leverages the Amazon Web Services (AWS) infrastructure to provide a managed platform for deploying applications. While DigitalOcean does not explicitly state this, it is likely that the majority of the functionality and features offered by DigitalOcean are based on AWS. This is evident from the similarities in the user interface, billing, and management features. Additionally, DigitalOcean has integrated AWS features into its own platform, such as the ability to create and manage Amazon EC2 instances from the DigitalOcean Control Panel.
This integration allows DigitalOcean customers to take advantage of the full range of AWS features and capabilities without having to learn a different platform. Taken together, these similarities make it likely that DigitalOcean is based on AWS.
