Terraform Module will create the VPC, Subnets, Route Table, NACL, VPC Endpoints

terraform-aws-vpc

This module creates the basic and advance network resources for a region.

The following resources will be created:

• Virtual Private Cloud (VPC)
• VPC Flow Logs
• AWS Cloudwatch log groups
• Subnets
  • Public
  • Private
  • Database
• Internet Gateway
• Nat Gateway
• Route tables for the Public, Private, Database subnets
• Associate all Route Tables created to the correct subnet
• Database Subnet group - Provides an RDS DB subnet group resources without Internet
• Adding routes in Route Table for VPC Peering
