PDFs
Cloud Manager creates AWS security groups that include the inbound and outbound rules that Cloud Manager and Cloud Volumes ONTAP need to operate successfully. You might want to refer to the ports for testing purposes or if you prefer your to use own security groups.
Rules for Cloud Manager
The security group for Cloud Manager requires both inbound and outbound rules.
Inbound rules for Cloud Manager
The source for inbound rules in the predefined security group is 0.0.0.0/0.
