Hi, Rob,

Appreciate your suggestions. Please see my inline comments.

Yeah, it's on the roadmap (may happen in several days.)

Qinling already supports plugable storage. In order to make it easy to
test, the default is local file system. But it's up to deployer to decide
which storage solution to use.

Qinling supports Keystone for authentication. RBAC is on the roadmap.

This needs to be discussed further. Currently, the code is executed inside
container which locates in orchestration system. Not sure it's easy to make
that container access tenant network.

Currently, user could invoke function by calling Qinling's rest api, but I
agree with you that an API Gateway service is indeed necessary to provide
more flexibility to end users.
