However, it is not automatically created as part of the default configuration of a new VPC. While other features such as route tables, network access control lists (ACLs), and security groups are created by default with a VPC, an Internet gateway must be explicitly created and attached to the VPC to facilitate internet access. The route table is necessary for managing the routing of packets within the VPC. Every new VPC comes with a default route table, which helps define how instances within the VPC can communicate with each other and, potentially, with external networks. A network ACL is another default feature that operates at the subnet level, allowing you to control inbound and outbound traffic to and from your subnets. Each new VPC automatically comes with a default network ACL that permits all traffic. Security groups, often referred to as virtual firewalls for your instances, are also created by default upon the creation of a VPC. They provide instance-level security and govern the traffic allowed to and from Amazon EC2 instances within the VPC. In summary, while route
