I had a similar setup a couple of years ago, where I had to deploy without downtime. My solution was to simply have the old version running in parallel until I was certain the new version was ok
----------
Static website:
1. Setup NginX using a symlink to the current version
2. Copy the new files to a separate folder
3. Change the symlink to point to the new version
----------
REST service (behind NgninX reverse proxy):
1. Current version runs on port X.
2. Deploy new version and run it on port Y.
3. Update NginX config to use port Y and reload
4. If you need rollback, just reverse step 3.
This can be done using scripts or Ansible too if necessary.
