[Openstack] [Folsom] How VM is connected to Swift storage

Hi all,

I would like to ask you for some explanations about OpenStack production
use case, I don't understand how my new VM will be connected to Swift
storage nodes.

It is not yet finished, but my OpenStack deployment will look like this: 2
cloud controller nodes (keystone, glance, cinder, quantum, nova, rabbit,
mysql..) and 2 compute (nova-compute) nodes. Next, I will have 1 Swift
Proxy and 3 Swift Storage nodes.

When the time comes to migrate our clients, I will create VMs and transfer
those web applications.

My question is: will the BLOBS (images, videos, user upload files..) of
that web apps, be automatically saved into Swift storage? Or, our
developers will have to change that every single application's code and
tell them to save and retrieve BLOBS from remote Swift servers?

Thanks in advance!
