Why does the Meraki dashboard API return a 404 rather than a 403 code in response to a request with an invalid API key?

The 404 return code determines whether unauthorized users will try again.
The 403 return code would indicate that the client definitely has an invalid API key.
The 404 return code prevents the system from indicating the existence of resources to unauthorized users.
The 403 return code would indicate that there are no resources at that endpoint but the API key could be correct.

The 404 return code prevents the system from indicating the existence of resources to unauthorized users.

In the use of container technologies, what is a function of platform abstraction when considering the deployment of a product in a cloud environment? Traditional complementary software components such as a database server and web server would be implemented as a single containerized application. Applications require re-engineering in order to implement scalability and consolidation. A containerized app can run on a generically-specified host environment. Applications are aware of underlying hardware configurations and are customized to provide increased functionality.
