What is AWS?

AWS (Amazon Web Services) is a cloud computing platform developed by Amazon. It offers a broad set of services such as computing power, storage, networking, databases, artificial intelligence, analytics, and more—all delivered over the internet on a pay-as-you-go model.

Launched in 2006, AWS has grown into the world’s most widely adopted cloud platform. According to industry reports, AWS holds over 30% of the global cloud market share, outperforming competitors like Microsoft Azure and Google Cloud.

Key Benefits of AWS

  1. Scalability – Instantly scale resources up or down based on demand.
  2. Cost-Effectiveness – Pay only for what you use with no upfront investment.
  3. Global Reach – Data centers (called regions and availability zones) spread across the world.
  4. Security – AWS offers strong compliance, encryption, and identity management features.
  5. Flexibility – Choose from hundreds of services for different workloads.

In short, AWS allows businesses to focus on innovation rather than managing expensive physical infrastructure.

Core AWS Services You Must Know

AWS has 200+ services, but as a beginner, you don’t need to learn all of them. Let’s break down the most important categories:

1. Compute Services

These services provide the processing power to run applications.

  • Amazon EC2 (Elastic Compute Cloud): Virtual servers in the cloud.
  • AWS Lambda: Serverless computing that runs code without provisioning servers.
  • Amazon ECS & EKS: Container services for Docker and Kubernetes.

2. Storage Services

Reliable and secure storage options.

  • Amazon S3 (Simple Storage Service): Object storage for files, images, backups.
  • Amazon EBS (Elastic Block Store): Persistent block storage for EC2 instances.
  • Amazon Glacier / S3 Glacier: Low-cost storage for archiving.

3. Database Services

Managed databases for structured and unstructured data.

  • Amazon RDS: Relational databases (MySQL, PostgreSQL, Oracle, SQL Server).
  • Amazon DynamoDB: Fully managed NoSQL database.
  • Amazon Redshift: Data warehouse for analytics.

4. Networking Services

Services for connecting and securing applications.

  • Amazon VPC (Virtual Private Cloud): Isolated cloud network.
  • Elastic Load Balancer (ELB): Distributes traffic across servers.
  • Route 53: Scalable domain name system (DNS).

5. Security and Identity

  • AWS IAM (Identity and Access Management): Controls access to resources.
  • AWS KMS (Key Management Service): Manages encryption keys.
  • AWS WAF (Web Application Firewall): Protects web apps from threats.

6. Analytics and AI

  • Amazon Athena: Query data in S3 using SQL.
  • Amazon SageMaker: Build, train, and deploy machine learning models.
  • Amazon QuickSight: Business intelligence and data visualization.

7. DevOps and Management Tools

  • AWS CloudFormation: Infrastructure as code.
  • AWS CloudWatch: Monitoring and logging.
  • AWS CodePipeline: CI/CD automation.

Getting Started with AWS: Step-by-Step Guide

Now that you know the basics, let’s walk through how to get started with AWS.

Step 1: Create an AWS Free Tier Account

AWS offers a 12-month free tier, allowing beginners to explore services like EC2, S3, and RDS at no cost (within limits).

  1. Visit aws.amazon.com
  2. Click Create an AWS Account
  3. Enter your email, password, and billing details
  4. Enable MFA (Multi-Factor Authentication) for security

Step 2: Access AWS Management Console

Once registered, log into the AWS Management Console, a web-based interface to manage all AWS services.

Step 3: Launch Your First EC2 Instance (Virtual Server)

  1. Go to EC2 Dashboard
  2. Click Launch Instance
  3. Choose Amazon Linux 2 or Ubuntu as your operating system
  4. Select a t2.micro instance (free tier eligible)
  5. Configure security group (allow SSH and HTTP traffic)
  6. Launch the instance and connect via SSH

Step 4: Store Files in Amazon S3

  1. Open S3 Service
  2. Create a new bucket (e.g., myfirstbucket123)
  3. Upload files (images, documents, etc.)
  4. Enable public access to make files available online

Step 5: Deploy a Simple Web Application

  • Use EC2 + S3 + RDS to host a web app.
  • Or go serverless with AWS Lambda + API Gateway + DynamoDB.

Congratulations! You’ve just set up your first AWS environment.
