Kota, Thanks for your reply, very helpful!
I know Storlets can provide user-defined computation functionalities, but I guess some capabilities can only be achieved using middleware. For example, a user may want such a feature: upon each PUT request, it creates a compressed copy of the object and stores both the original copy and compressed copy. It's feasible using middlware but I don't think Storlets provide such capability. Another example is that a user may want to install a Swift3-like middleware to provide APIs to a 3rd party, but she doesn't want other users to see this middleware.
