How to connect to an EC2 instance without a key pair / Access EC2 with the AWS SSM Session Manager

How to connect to an EC2 instance without a key pair. I will show you how you can access an Amazon EC2 instance even if you've lost the .pem file, using the AWS Systems Manager (SSM) Session Manager.

ABOUT THE AWS SSM AGENT:
AWS Systems Manager Agent (SSM Agent) is Amazon software that can be installed and configured on an EC2 instance, an on-premises server, or a virtual machine (VM). SSM Agent makes it possible for Systems Manager to update, manage, and configure these resources.

ABOUT AWS SSM SESSION MANAGER:
Session Manager is a fully managed AWS Systems Manager capability that lets you manage your Amazon Amazon EC2 instances, on-premises instances, and virtual machines (VMs) through an interactive one-click browser-based shell or through the AWS Command Line Interface (AWS CLI). Session Manager provides secure and auditable instance management without the need to open inbound ports, maintain bastion hosts, or manage SSH keys.

You need the following three things to connect to an instance using SSM Session Manager:

1: Make sure that the AWS Systems Manager Agent is running on the instance
2: Make sure that the instance can communicate with the AWS Systems Manager
3: Use the AWS Systems Manager Session Manager to connect to the instance

I am going to show you all three steps. how to check if the SSM Agent is installed, how to configure your EC2 instance to communicate with SSM, and how to connect to the instance using the SSSM Session Manager.
