VPC

The system will create a security group for each user by default, The rule of the default security group is to pass all data packets on the outgoing room, Restricted access in the inbound direction, The elastic cloud servers in the security group can access each other without adding rules.

Security group is a logical grouping, Provide access policies for mutually trusted elastic cloud servers in the same VPC that have the same family protection requirements.

After the security group is created, Users can define various access rules in the security group, When the elastic goes to the server to join the group or the whole group, It is protected by these access rules.

When configuring security group rules, The source and destination addresses can only be set as IP addresses, It cannot be a security group.
