Understand what Amazon EC2 is
Earlier, we learned that
Introduction to Amazon EC2
Virtual server in AWS cloud
Provides compute capacity on demand
Supports scaling, security
Types of EC2 Instances
General Purpose
Compute Optimized
Memory Optimized

Accelerated Computing
Instance Families
Explain families like
T / M → Balanced
C → Compute heavy
R / X → Memory heavy

EC2 Pricing Models Overview
Reserved Instances (RI)
Up to 70% discount
Commitment: 1-year or 3-year
Best for steady workloads
Spot Instances
Up to 90% discount
Uses unused AWS capacity
Can lose instance anytime
Interruption notification (2-minute warning)
Best for fault-tolerant jobs
Dedicated Instances
Single-tenant hardware
Used for compliance & licensing
Higher cost than shared instances
On Demand Instances
Pay-as-you-go pricing
No long-term commitment
Best for short-term or unpredictable workloads
Summary
