Amazon Web Services (AWS) Tutorial

Overview

Amazon Web Services (AWS) is a comprehensive cloud computing platform provided by Amazon. It offers a broad range of cloud services including computing power, storage options, and networking capabilities. AWS is widely used for scalable applications, data processing, and enterprise solutions.

Introduction to AWS

What is Amazon Web Services?

Amazon Web Services is a cloud platform offering a variety of services including computing power, storage, and databases. It enables users to build, deploy, and manage applications through Amazon's global network of data centers.

Key Features

Scalability: Easily scale resources up or down based on demand.
Global Reach: Data centers around the world ensure low-latency access.
Security: Advanced security features and compliance certifications.
Flexibility: Support for various programming languages, frameworks, and tools.

AWS Services

Compute Services

Amazon EC2: Scalable virtual servers in the cloud.
AWS Lambda: Serverless computing service for running code without provisioning servers.
Amazon ECS: Managed container service for running Docker containers.

Storage Services

Amazon S3: Object storage for scalable storage of unstructured data.
Amazon EBS: Block storage for Amazon EC2 instances.
Amazon Glacier: Low-cost archival storage for long-term data backup.

Database Services

Amazon RDS: Managed relational database service for SQL databases.
Amazon DynamoDB: Managed NoSQL database service.
Amazon Aurora: High-performance relational database compatible with MySQL and PostgreSQL.

Monitoring and Management

Amazon CloudWatch: Monitoring service for AWS resources and applications.
AWS CloudTrail: Service that enables governance, compliance, and operational auditing.

Amazon EC2

Launching an EC2 Instance

Amazon EC2 allows you to create and manage virtual servers in the cloud.

Example: Launching a New EC2 Instance using AWS CLI

aws ec2 run-instances \
  --image-id ami-0abcdef1234567890 \
  --count 1 \
  --instance-type t2.micro \
  --key-name my-key-pair \
  --security-group-ids sg-0123456789abcdef0 \
  --subnet-id subnet-0123456789abcdef0

Amazon S3

Storing and Retrieving Data

Amazon S3 provides scalable object storage for unstructured data.

Example: Uploading a File to S3

aws s3 cp local-file.txt s3://my-bucket/

Example: Downloading a File from S3

aws s3 cp s3://my-bucket/remote-file.txt local-directory/

Amazon RDS

Managing Relational Databases

Amazon RDS is a managed relational database service for various SQL databases.

Example: Creating an RDS Instance

aws rds create-db-instance \
  --db-instance-identifier mydbinstance \
  --db-instance-class db.t2.micro \
  --engine mysql \
  --master-username admin \
  --master-user-password password \
  --allocated-storage 20

Example: Connecting to an RDS Database

mysql -h mydbinstance.c9akciq32.rds.amazonaws.com -u admin -p

AWS Lambda

Creating Serverless Functions

AWS Lambda allows you to run code in response to events without managing servers.

Example: Creating a Lambda Function

aws lambda create-function \
  --function-name my-function \
  --runtime python3.8 \
  --role arn:aws:iam::123456789012:role/service-role/my-role \
  --handler lambda_function.lambda_handler \
  --zip-file fileb://function.zip

Example: Lambda Function Code (Python)

def lambda_handler(event, context):
    return {
        'statusCode': 200,
        'body': 'Hello, world!'
    }

Amazon ECS

Managing Docker Containers

Amazon ECS is a managed container service for running Docker containers.

Example: Creating an ECS Cluster

aws ecs create-cluster --cluster-name my-cluster

Example: Running a Task

aws ecs run-task \
  --cluster my-cluster \
  --task-definition my-task-definition

Amazon CloudWatch

Monitoring AWS Resources

Amazon CloudWatch provides monitoring and logging for AWS resources and applications.

Example: Creating a CloudWatch Alarm

aws cloudwatch put-metric-alarm \
  --alarm-name my-alarm \
  --metric-name CPUUtilization \
  --namespace AWS/EC2 \
  --statistic Average \
  --period 300 \
  --threshold 80 \
  --comparison-operator GreaterThanOrEqualToThreshold \
  --evaluation-periods 1 \
  --alarm-actions arn:aws:sns:us-east-1:123456789012:my-topic

AWS CLI

Using the AWS Command Line Interface

The AWS CLI is a tool to manage AWS services from the command line.

Example: Installing AWS CLI

curl "https://d1uj6qtbmh3dt5.cloudfront.net/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

Example: Configuring AWS CLI

aws configure

Example: Listing EC2 Instances

aws ec2 describe-instances
