Applies to

  • Cloud Volumes ONTAP (CVO)
  • Amazon Web Services (AWS)
  • Cloud Manager
  • Internal and External Security Group configuration

Answer

  • Cloud Manager creates AWS security groups – which include inbound and outbound rules – that Cloud Manager and CVO need to operate successfully
  • You can create your own rules or edit predefined ones, if required

Example:

Predefined external security group for CVO HA mediator includes 2 inbound rules, allowing SSH access (port 22) and TCP port 3000 for RESTful API access from Cloud Manager. By default, those two rules allow all IPs to connect (source is 0.0.0.0/0).

  • You can restrict source IPs for those rules, if needed

Example:

  • SSH port 22: allows only trusted Public IPs or disable SSH access from outside of network
  • TCP port 3000: allows only Cloud Manager IP
For information on necessary ports and protocols for each instance, see Cloud Manager - Security group rules for AWS documentation.
