Explain VPC, NAT Gateway, difference between NACL and SG

Question

Accepted Answer

VPC is a virtual private cloud that allows you to create isolated networks, NAT Gateway enables instances in a private subnet to connect to the internet, NACL controls inbound and outbound traffic at the subnet level, SG controls traffic at the instance level.

VPC is a virtual network in the cloud that you can define and customize, providing a secure environment for your resources.
NAT Gateway allows instances in a private subnet to access the internet while remaining private.
Network Access Control Lists (NACL) are stateless and control traffic at the subnet level based on rules you define.
Security Groups (SG) are stateful and control traffic at the instance level based on rules you define.
For example, you can use a NACL to block specific IP addresses from accessing resources in a subnet, while using a SG to allow only specific ports to be accessed by instances.
