Mastering AWS Commands: A Comprehensive Guide

Introduction:

Amazon Web Services (AWS) is a leading cloud platform that provides a vast array of services for computing, storage, machine learning, and more. In this comprehensive guide, we'll explore essential AWS commands, empowering you to navigate and manage cloud resources efficiently.

Chapter 1: AWS Command-Line Interface (CLI) Installation:

Get started with AWS CLI using these commands:

aws configure

aws help

aws --version

These commands configure AWS CLI, display help information, and show the AWS CLI version.

Chapter 2: AWS Identity and Access Management (IAM) Commands:

Manage IAM users, roles, and policies with these commands:

aws iam create-user --user-name [username]

aws iam create-role --role-name [role-name] --assume-role-policy-document file://trust-policy.json

aws iam create-policy --policy-name [policy-name] --policy-document file://policy.json

These commands create IAM user, role, and policy, respectively.

Chapter 3: Amazon Simple Storage Service (S3) Commands:

Interact with S3 buckets using these commands:

aws s3 mb s3://[bucket-name]

aws s3 cp [local-file] s3://[bucket-name]/[remote-file]

aws s3 ls s3://[bucket-name]

These commands create an S3 bucket, copy files to S3, and list bucket contents.

Chapter 4: Amazon Elastic Compute Cloud (EC2) Commands:

Manage EC2 instances with these commands:

aws ec2 run-instances --image-id [ami-id] --instance-type [instance-type]

aws ec2 describe-instances

aws ec2 terminate-instances --instance-ids [instance-id]

These commands launch an EC2 instance, describe instances, and terminate an instance.

Chapter 5: Amazon Relational Database Service (RDS) Commands:

Operate RDS instances using these commands:

aws rds create-db-instance --db-instance-identifier [db-instance-id] --db-instance-class [db-instance-class]

aws rds describe-db-instances

aws rds delete-db-instance --db-instance-identifier [db-instance-id] --skip-final-snapshot

These commands create an RDS instance, describe instances, and delete an instance.

Chapter 6: AWS Lambda Commands:

Interact with AWS Lambda functions using these commands:

aws lambda create-function --function-name [function-name] --runtime [runtime] --handler [handler] --role [role-arn] --zip-file fileb://function.zip

aws lambda list-functions

aws lambda delete-function --function-name [function-name]

These commands create a Lambda function, list functions, and delete a function.

Chapter 7: AWS CloudFormation Commands:

Deploy and manage infrastructure as code using CloudFormation:

aws cloudformation create-stack --stack-name [stack-name] --template-body file://template.json

aws cloudformation describe-stacks

aws cloudformation delete-stack --stack-name [stack-name]

These commands create a CloudFormation stack, describe stacks, and delete a stack.

Chapter 8: AWS SNS (Simple Notification Service) Commands:

Send and manage notifications with SNS commands:

aws sns create-topic --name [topic-name]

aws sns list-topics

aws sns delete-topic --topic-arn [topic-arn]

These commands create an SNS topic, list topics, and delete a topic.

Chapter 9: AWS CloudWatch Commands:

Monitor resources and logs using CloudWatch commands:

aws cloudwatch put-metric-alarm --alarm-name [alarm-name] --metric-name [metric-name] --namespace [namespace] --statistic [statistic] --threshold [threshold]

aws cloudwatch describe-alarms

aws cloudwatch delete-alarms --alarm-names [alarm-name]

These commands create a CloudWatch alarm, describe alarms, and delete an alarm.

Chapter 10: AWS CLI Advanced Features:

Explore advanced AWS CLI features:

aws configure --profile [profile-name]

aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId,InstanceType,State.Name]' --output table

aws s3 sync [local-dir] s3://[bucket-name]/[remote-dir]

These commands configure profiles, customize query output, and synchronize local and S3 directories.

Chapter 11: AWS CLI and Bash Scripting:

Automate AWS tasks with CLI and Bash scripting:

#!/bin/bash

aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId,InstanceType,State.Name]' --output table

Create a Bash script to query and display EC2 instance details.

Chapter 12: AWS Best Practices:

Follow AWS best practices for optimal cloud management:

Resource Tagging: Tag resources for effective organization and cost allocation.

IAM Least Privilege: Grant minimal permissions required for tasks using IAM.

Multi-AZ Deployments: Implement multi-AZ deployments for high availability.

Data Encryption: Enable encryption for data at rest and in transit.

Backup and Recovery: Regularly backup and test recovery procedures.

Chapter 13: AWS Well-Architected Framework:

Align your architecture with AWS best practices:

aws wellarchitected help

aws wellarchitected describe-lens-reviews

Use AWS Well-Architected tools to assess and improve your architecture.
