An instance is a resource in API Gateway that can provide public IP, private IP, public network egress, computing, and storage resources required to process an API. A service must be mounted under an instance before it can run normally.
API Gateway provides shared instances and dedicated instances. For more details about their differences, see Instance Specifications.
