I wouldn't call it a CDN, but the caching infrastructure at Google may hold on to static assets with the correct headers set. One of the key benefits here is that you won't be charged CPU time for serving the asset, though bandwidth charges will still be applied. This is only a best effort caching and is not guaranteed, so in the worst case scenario the caching infrastructure will not hold on to your data and the requests will still be routed to your application instances.
