Learn how to log into and automate the creation of virtual machines on AWS

- Use AWS console to log into the EC2 instance and execute commands

- Installing a terminal in your personal laptop to connect to the virtual machine

Choose the right terminal based on your computer's operating system

- For Mac, use iTerm as it is the recommended terminal

- For Windows, options like PuTTY and Mobile Xterm are available

Learned how to connect to a virtual machine and create a file

- Understood the importance of keeping pem file permissions closed

- Explored CLI and UI methods to connect to an AWS instance

Stop and terminate instances to avoid unnecessary billing

- Stopping an instance allows you to save costs by not being billed for the time it's in a running state

- Terminating an instance deletes it permanently

- Using AWS CLI is an easy and automated way to interact with your AWS account

- You can download and install AWS CLI on Windows, Mac OS, or Linux

- Verify the installation by running 'AWS version' command

- Authenticate AWS CLI with your AWS account by creating access keys

Configure AWS CLI and access key

- Retrieve AWS access key and secret access key from AWS console

- Use 'AWS configure' command to enter access key ID, secret access key, and other details

- Use 'AWS S3 LS' command to list S3 buckets

- Use 'AWS S3 MB' command to create a new S3 bucket

- Refer to AWS documentation for specific commands

AWS CLI and CloudFormation are two ways to interact with AWS API.

- Use AWS CLI to create an EC2 instance by providing necessary information like instance type, key value pair, location, security groups, and subnet ID.

- Create security credentials and authenticate to use AWS CLI.

- Refer to the AWS CLI documentation for pre-available commands.

- Store the commands in a shell or Python script or in a GitHub repository for automation purposes.

- CloudFormation templates provide another way to interact with AWS API.

- Refer to the AWS Labs GitHub repository for a wide range of CloudFormation template examples.

- Upload a CloudFormation template file to create resources on AWS.

Automating tasks in AWS using Python with the boto3 module

- Learn how to install boto3 and configure it with AWS credentials

- Use boto3 to write Python scripts for automating AWS tasks such as listing EC2 instances

Learn how to install AWS CLI package and use it to interact with AWS services

- Follow the AWS CLI documentation to understand the available commands and examples

- Create S3 buckets, list EC2 instances, or perform any other desired actions using AWS CLI
