What is AWS?
Amazon Web Services (AWS) is Amazon’s powerhouse cloud computing platform.
Instead of setting up physical servers or complex infrastructure, AWS lets you build apps, store data, host websites, run analytics, and automate processes — all through the internet.
Today, AWS powers startups, enterprises, government institutions, students, and millions of others around the globe.
“No server rooms. No delays. Just launch, scale, and grow.”
Why Do Companies Choose AWS?

| Global reach | 30+ geographic regions and data centers worldwide. |
| Enterprise security | Advanced layers like IAM, VPC, encryption, firewalls, and more. |
| Flexibility | 200+ services — from no-code tools to full-stack dev platforms. |
| Automation | Need a dev environment? Launch an EC2 instance in under 3 minutes! |
What Does AWS Actually Offer?
AWS has hundreds of services, but here are the essentials:
EC2 (virtual servers)
S3 (cloud storage)
RDS / DynamoDB (relational + NoSQL databases)
CloudFront (global CDN)
Lambda (serverless functions)
SES (email service)
Route 53 (DNS)
ElastiCache (caching)

AWS Core Services – The Foundation of Everything
Let’s explore the services that power today’s most scalable apps:
1. Amazon EC2 (Elastic Compute Cloud)
“Spin up your own virtual server — fast.”
Use cases: web hosting, API backends, game servers, development environments
Highlights:
Multiple instance types (CPU, RAM, GPU)
Elastic Load Balancer
Auto Scaling
Pay per second
EC2 = renting your own digital office space.
2. Amazon S3 (Simple Storage Service)
“Store your data in the cloud and access it from anywhere.”
Use cases: media storage, website backups, video streaming, static site hosting
Features:
Versioning for file history
Lifecycle rules for auto-archiving
Encryption options
Buckets for organized storage
3. Amazon RDS (Relational Database Service)
“Manage your data, not the database server.”
Supports: MySQL, PostgreSQL, Oracle, SQL Server, MariaDB, Aurora
Perfect for: eCommerce, CRMs, ERPs
Perks:
Automated backups
Multi-AZ for disaster recovery
IAM-based access
4. Amazon DynamoDB
“A serverless NoSQL beast — built for scale.”
Use cases: mobile apps, IoT, real-time leaderboards
Key features:
Instant scaling
Millisecond performance with DAX caching
JSON-like data model
5. Amazon Route 53
“Fast, reliable DNS routing with built-in health checks.”
Use cases: global apps, multi-region failovers, domain registration
Directs users to the closest edge location
Monitors server uptime
Supports domain management
6. Amazon CloudFront
“Serve your content at lightning speed — globally.”
CDN that mirrors your site’s assets to edge locations around the world.
Use cases: video streaming, SPAs, high-traffic websites
These six services are your AWS essentials. Mastering them gives you the foundation to build virtually anything in the cloud.
Advanced AWS Services – Speed, Automation, and Power
Ready to go beyond the basics? These services will take you there:
1. AWS Lambda
“Run code without provisioning servers.”
How it works: Lambda runs your code automatically in response to triggers — like uploading a file, or submitting a form.
Use cases:
Auto-send emails
API backend
Image resizing
Benefits:
No server maintenance
Second-based billing
Auto-scaling
2. Amazon ElastiCache
“Turbocharge your database performance.”
Supports: Redis & Memcached
Use cases:
Shopping carts
Caching API responses
Real-time dashboards
Reduces DB load and delivers sub-millisecond response times.
3. Amazon MQ
“Build reliable communication between services.”
Supports: RabbitMQ, ActiveMQ
Use cases:
Order processing
Event notifications
Microservices architecture
MQ = message queues = better performance & system stability
4. Amazon SES (Simple Email Service)
“Send thousands of emails with one API call.”
Use cases:
Marketing newsletters
Account verification emails
Password resets
Features:
SMTP or API integration
Low spam risk
High deliverability
Rich reporting
Example: S3 upload → Lambda trigger → SES email = a fully automated notification system
