Step 05

Step 07: Key pair​

Select Proceed without a key pair (Not recommended).

We will use EC2 Instance Connect to access the instance directly from the AWS Console, so a key pair .pem file is not needed for this setup.

Step 08: Addition of a vpc​

A VPC is a private ip address range which identifies your newly created machine inside AWS network using its IP address. One default VPC is already made in AWS and if you accidentally deleted it you can create one using this guide - [[Chapter 4 Making a default vpc]]

Step 09: Attaching/creating a Security Group​

This step is common while creating RDS and EC2 both. A security group tells who in world can connect to this app. Security group has security rules attached to it. Here we are quickly creating one and allowing everyone in world in aws and outside aws to be able to connect to our app. You can use same security group for multiple apps also but for this time we are creating one specific for EC2.

We are now attaching a IAM role with this EC2 because we want to connect to our machine from AWS SSM manager (cmd inside aws) instead of having a saperate app for it. for SSM manager we need to attach a IAM role to our EC2 Machine Pasted image 20260824205137.png

After that click SSM session manager -> then click connect (we created IAM profile to connect with SSM session manager)
