Terraform VPC - on AWS : Three tier architecture design

Image
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++   +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ We are going to build a three tier architecture as follows.   AWS Management Console : First Build manually  We are going to build a VPC \ We are going to create public and private subnets under two different available zone . Two more private subnets for database. In addition to that we are going to create an InternetGateway.  And add the routes for the public subnets where by incoming traffics are also allowed by this public subnets. In addition to that we will create NAT Gateway with elastic IPs. Therefore the EC2 instances in the private subnet can communicate to the internet world using the NAT gateway created on the Public subnets.  Above diagram represents what we are planning to build. We will learn about Terraform Modules and Local Values.    43 . Building VPC Manually using AWS Console. http...
