This page lists what Galactic VPC networks can’t do and the networking capabilities that Datum is working on.
Galactic VPC is in preview, and the networking.datumapis.com/v1alpha API can change.

Limitations

In addition to the networking limitations that apply to all of Compute, networks have the following limitations:
  • Each workload attaches to exactly one network through one network interface, and it can’t move to another network.
  • Instance addresses aren’t reachable from the internet. To serve traffic publicly, attach an ALB to the workload.
  • The networkPolicy field of a network interface has no effect. Don’t rely on it to restrict traffic. Firewall rules are a planned capability.
  • You can’t choose a network’s address ranges or create your own subnets.
  • Networks carry Compute traffic only in the locations where Compute runs: us-central-1, us-east-1, and us-west-1.

Planned capabilities

Datum is working on the following networking capabilities:
  • Outbound internet access: Per-network control of internet access from Instances, starting with IPv6 destinations, and visibility into the address that the traffic leaves from.
  • IPv4 destinations: Access to internet services that have only IPv4 addresses, from Instances that have only IPv6 addresses.
  • Firewall rules: Security groups that control the traffic to and from your Instances.
  • Private DNS: Private DNS names, so Instances can find each other without IP addresses.
  • Networks in the portal: Viewing and managing networks in the Datum Cloud portal.
Plans can change. This list isn’t a commitment to deliver any feature or to meet any timeline.
