Automate and manage your AWS EC2 instances efficiently using your preferred terminal or SSH client

Once you've provisioned an AWS EC2 instance, you can automate various tasks and establish connections to it from your local machine using your preferred terminal or SSH client.

Here are the general steps for connecting to an EC2 instance:

✨ Obtain the Public IP Address:

Your EC2 instance is typically assigned a public IP address.You can find this IP address in the AWS Management Console or by using the AWS CLI.

✨ SSH Key Pair:

Make sure that you have the private key (.pem) associated with the key pair you specified when launching the instance. Keep this key secure.

✨ Connect from Your Terminal (macOS and Linux):

· Use the SSH command to establish an SSH connection to the EC2 instance. Replace [your EC2 public IP] with the actual public IP address and [path of your private key.pem] with the path to your private key file:

ssh -i /path/to/your-private-key.pem ec2-user@[Public IP of your EC2]

Note: A PEM file is a secret file and has sensitive information and sometimes your resources might get shared e.g. while using a shared VM. Pem files don't let you keep the file open so, keep the permissions closed e.g. with chomd 600 followed by your Pem file location.

✨Connect from Windows:

· If you're using Windows, you can use tools like PuTTY, MobaXterm, or NoMachine to connect to your EC2 instance.

✨Automate Tasks with Scripts:

· You can write and execute shell scripts or other automation scripts on the EC2 instance to perform various tasks. For example, you might use shell scripts to install software, configure the environment, or deploy applications.

✨Security Considerations:

· Ensure that you keep your private key secure and don't share it with unauthorized users.

· Configure security groups and network ACLs to control inbound and outbound traffic to your EC2 instance.

· Consider using IAM roles and policies to manage access to AWS resources from your EC2 instance securely.
