We don&#x27;t really have an equivalent to Lambda (yet?) but classic App Engine isn&#x27;t actually too far off &#x27;technology-wise&#x27; (pay per use, containerized, instant start).<p>Our lack of IAM is <i>beyond</i> painful. We&#x27;re sorry. We&#x27;re fixing it.<p>PD has had snapshots since Day 1; they&#x27;re differential, fast and we even encourage people to use them for super-fast &quot;rsync&quot;!
