2. How the workers of a cluster can download dependencies from the internet, if the cluster nodes have no egress/ingress allowance.<br>
3. How Cloud Datastore and Spanner and Spanner vs Bigtable are different?<br>
4. 2 PB of data (key, value) where will you store, Datastore, Spanner, Bigtable?. What about 1 TB?<br>
5. Storage transfer service vs transfer appliance. Can you use a private web address to transfer 2 PB of data over six months with storage transfer service?\
