**Project Title : Creating a EC2 instance with a Security group SSH access **

This is a project to create a stack using aws cloudformation. You can use visual designer, sample template or upload a template file. I usually use a sample template and edit it as i work along but your free to do what you please.

On this particular project we will use aws cloudformation to launce a ec-2-instance with a Security group for SSH access. Importantly we need to create a security group first the attach it to the ec-2-instance.

Secondly, we will add a volume and attach it to our ec-2-instance without changing the cloudformation configuration.

Lasty, we will the add S3 bucket to number 1 and number 2. That is without changing the original values.

Note : I picked the current image id of Amazon Linux { ami-098e39bafa7e7303d }

Deployment

To deploy this project sign in your aws console, and launch aws cloudformation. You can copy and save this file as aws-cloudformation.yaml or aws-cloudformation.json using vscode and upload it into the console.

2.0 Attaching an EBS Volume to the ec-2 Instance

I created a 25 GB Volume using the same ec-2 instance properties and then we wil attach the Volume to the ec-2
