Compute¶

Running code — from bare metal to serverless.

The Compute Spectrum¶

Most control                                          Least control
     ↓                                                      ↓
Bare Metal → EC2 → Containers (ECS/EKS) → Lambda (serverless)

More control = more you manage. Less control = AWS manages more, you pay for simplicity.

Note	What It Covers
EC2 Deep Dive	Instance types, storage, networking, pricing
Lambda	Event-driven serverless — triggers, limits, cold starts
AWS Nitro System	The hardware/hypervisor stack under EC2

Key Decision Framework¶

Scenario	Choose
Full OS control needed	EC2
Containerised workload	ECS (Fargate) or EKS
Event-triggered, short-lived	Lambda
Legacy lift-and-shift	EC2
API backend, variable traffic	Lambda or Fargate
