An Elastic IP address is associated with your AWS account. It is hardened in this manner primarily due to its location and purpose, which is either on the outside of a firewall or in a demilitarized zone (DMZ) and usually involves access from untrusted networks or computer.Īn Elastic IP address is a static IPv4 address designed for dynamic cloud computing. The computer generally hosts a single application, for example a proxy server, and all other services are removed or limited to reduce the threat to the computer. Don't forgot to add auto ip assign and auto dns name assignment option to be enabled.Ī Bastion Host is a special-purpose computer on a network specifically designed and configured to withstand attacks. MySQL instance has to be part of private subnet so that outside world can't connect to it. Note for task: Wordpress instance has to be part of public subnet so that our client can connect our site. Also attach the key to instance for further login into it.Ĩ. Launch an ec2 instance which has MYSQL setup already with security group allowing port 3306 in private subnet so that our wordpress vm can connect with the same. Create a routing table for Internet gateway so that instance can connect to outside world, update and associate it with public subnet.ĥ. Create a NAT gateway for connect our VPC/Network to the internet world and attach this gateway to our VPC in the public networkĦ. Update the routing table of the private subnet, so that to access the internet it uses the nat gateway created in the public subnetħ. Launch an ec2 instance which has Wordpress setup already having the security group allowing port 80 sothat our client can connect to our wordpress site. Create a public facing internet gateway to connect our VPC/Network to the internet world and attach this gateway to our VPC.Ĥ. The process will be almost the same except that NAT gateway part of the Problem Statement i.e Perform task-3 with an additional feature to be added that is NAT Gateway to provide the internet access to instances running in the private subnet.ġ. Write an Infrastructure As Code using Terraform, which automatically create a VPC.Ģ. In that VPC we have to create 2 subnets:ġ. Like in my previous article, this time also we going to launch the WordPress instance in public subnet and MySQL instance in the private subnet. And that’s the issue we are going to solve this time, that is we’ll give internet access to instances in the private subnet as well. In my previous article, I had discussed creating a web portal on AWS which would be very much secure, but in that after creating VPC, and creating two subnets, public and private, I noticed that instance in the private subnet(Mysql) doesn’t really have internet access. Hello there! Today we're going to add NAT Gateway to provide internet access to instances running in the private subnet.
