EC2 Core Concepts
Important EC2 concepts include AMIs, instance types, EBS volumes, security groups, key pairs, subnets and public/private networking.
Why it matters
Each concept controls a different part of the virtual server environment.
How it works
AMI provides the starting image, instance type supplies compute capacity, EBS stores persistent block data, security groups control network traffic, and networking determines reachability.
Core Concept
An instance is launched from an AMI and runs with an instance type, network settings, storage and security controls.
Example: host a Spring Boot application on an Ubuntu EC2 instance.
