   • Associate subnets with route tables.
4. Set Up NACLs:
   • Configure inbound and outbound rules.
   • Associate NACLs with subnets.
5. Implement Security Groups:
   • Define inbound and outbound rules.
   • Associate security groups with instances.
6. Add Internet Gateway (IGW):
   • Attach IGW to VPC.
   • Update route tables for internet access.
7. Optional - NAT Gateway/Instance:
