  description: 'The Amazon EC2 API is a query API for managing EC2 compute, EBS volumes,

    and VPC resources. It is transported over HTTPS to a regional EC2 endpoint,

    and requests are signed using AWS Signature v4. This OpenAPI captures a

    representative subset of operations as an API Evangelist research artifact

    for the scalable-infrastructure topic.
