API Versions and Instances
After you create an API in Anypoint Platform, you configure the version details for the API and then publish it to Anypoint Exchange (Exchange). The API version resides in Exchange, and not in API Manager. However, you then manage this API version from API Manager:
You can create, import, and deprecate API instances using API Manager. You can use instances of an API in multiple environments. You can also have multiple instances of an API in the same environment.
You can create one instance of an API version that serves as a proxy and create another to manage directly as an endpoint. You can apply policies to the API based on how the API is configured—proxy or endpoint. For example, you can apply caching policies to the proxy, and throttling policies and security policies to the endpoint.
Additionally, you can promote an API to another environment.
You can add, delete, and deprecate API versions, also known as Exchange assets, in Exchange. An API version in Exchange can have its own RAML file, API portal, and URL.
