@Generated(value="jsii-pacmak/1.104.0 (build e79254c)", date="2024-12-17T21:37:30.014Z") @Stability(Stable) public class Connections extends software.amazon.jsii.JsiiObject implements IConnectable
Manage the allowed network connections for constructs with Security Groups.

Security Groups can be thought of as a firewall for network-connected devices. This class makes it easy to allow network connections to and from security groups, and between security groups individually. When establishing connectivity between security groups, it will automatically add rules in both security groups

This object can manage one or more security groups.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ec2.*;
 IPeer peer;
 Port port;
 SecurityGroup securityGroup;
 Connections connections = Connections.Builder.create()
         .defaultPort(port)
         .peer(peer)
         .securityGroups(List.of(securityGroup))
         .build();
