Performance limitations for security groups
Some performance limitations exist for security groups and their associated rules.
| Resource | Limit |
|---|---|
| Security groups per network interface | 5 |
| Security groups per account | 500 |
| Rules per security group | 50 |
| Remote rules per security group | 5 |
| Network interfaces per security group | 100 |
A remote rule is one that specifies a security group as the source or destination. The "Remote rules per security group" resource row illustrates the number of rules that can contain a single security group as a remote group. A maximum of 5 rules can point to a given security group in their remote group field. This is a limit on the number of rules that can reference one security group. Because of performance restrictions, this limit should be set to 0 if you intend to set the "Network Components per security group" limit above 250.
