Security group rules for AWS Edit on GitHub Request doc changes

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.

SSH

22

Provides SSH access to the Cloud Manager host

HTTP

80

Provides HTTP access from client web browsers to the Cloud Manager web console

HTTPS

443

Provides HTTPS access from client web browsers to the Cloud Manager web console

Outbound rules for Cloud Manager

The predefined security group for Cloud Manager opens all outbound traffic. If that is acceptable, follow the basic outbound rules. If you need more rigid rules, use the advanced outbound rules.
