Launching a VPC with Public & Private subnet & NAT Gateway in AWS using Terraform!

This blog will guide you to create a VPC &2 subnets in it, one is public & another one is private. Then WordPress ec2 instance will be created in the public subnet, & a MySQL instance in the Private subnet. The MySQL instance will only allow the WordPress instance to connect and that too only for the database. Therefore to do any updates in the MySQL instance, one more ec2 instance known as Bastion Host or Jump Box will be created to access the MySQL instance. For MySQL to connect to the Internet, a NAT Gateway is created in the public subnet. Multiple Security groups are also created in this complete process to provide optimal security!

Ever wondered about launching the whole infrastructure in just one command, yes, it seems to be impossible, but it is possible. In this blog, I will guide you to construct the complete Pipeline described in the Introduction section of this blog.
