How to Create EC2 Instance (Ubuntu 22.04) on AWS and Connect Via SSH using PEM

Hellooooo there,
Let me guess you have started your cloud journey and trying to find your way...right? same here :-)

We are going to set up our Instance or Virtual Machine if you prefer that. So, first things first ensure that you have a AWS account, You can set it up here.

• Launch EC2 Instance

• Configure Instance

• Connect to Instance

• Terminate Instance.

Launch EC2 Instance.

• Search for EC2 on the search bar then open it,on the EC2 Dashboard you will see Resources which shows the instances that are running and everything related to EC2.

• Under Launch Instance section there is the Launch Instance button that we'll use to create a new instance so click on it.

Configure Instance.

• Name and Tags
  You are going to give a name to your instance,

• Application and OS Images (Amazon Machine Image)
  Depending on the Operating system,application server and application you are dealing with you select AMI that suites you. (Under the Instance type you'd want to leave it unchanged since we are using the free tier but there are so many options!)

• Key pair (login)

This is an essential part since it deals with security. If by chance you share your service IP address they cannot access your server without any key.
We need to generate a key pair for our instance, so click in the create new key pair and proceed to give the key pair name, type and key file format (if you are using Mac or Linux to log in to the server select .pem and use .ppk if you are using windows).
A file with the key pair name will be downloaded to your device.(we'll use it later to connect to our instance do, so do)

• Network Setting
  Keep the subnet as it is and enable auto-assign public IP- this will assign a public IP after starting the vm.

• Create Security Group
  this controls traffic to the instance, you can leave it or customize it to your liking.

  The maximum storage for free tier is 30GB so feel free to adjust it accordingly.

Like so:

• To connect to your EC2 instance from ubuntu, open your terminal and run this command ( I am assuming that you saved your key pair in your home).

ssh -i path-to-key ec2-user@ip-address

example

ssh -i "SCA-emerald.pem" [email protected]
