Dataproc is pretty significant compared with other managed Hadoop&#x2F;Spark services. Here&#x27;s how:<p>- You get a cluster in under 90 seconds and with per-minute billing.<p>- This lets you start with a job, then start a Dataproc cluster as part of job execution, then save output and discard cluster<p>- You aren&#x27;t throttled by slow startup times, and you are not worried about rounding up your workloads to nearest hour<p>Plus Preemptible VMs support at 70% off, Custom Machines types, GCS as storage layer, very very fast networking, and interoperability with other GCP services.<p>(disclosure: work on GCP but not Dataproc)
