What Is Cloud Computing?
Cloud computing means using someone else's computers over the internet instead of buying your own hardware.
Cloud Providers Overview
Major cloud providers like AWS and GCP exist, but simpler alternatives are often better for learning and small projects.
Compute, Storage, and Network
Every cloud platform builds on three fundamentals: compute for running code, storage for keeping data, and network for connecting everything.
Regions and Availability Zones
Cloud resources exist in physical locations. Regions are geographic areas, and availability zones are separate data centers within those regions.
Shared Responsibility Model
Cloud providers secure the infrastructure, but you're responsible for securing your application, data, and access controls.
Cloud Costs and Free Tiers
Cloud costs can surprise you if you're not careful. Free tiers help you learn, but always set billing alerts before creating resources.
When Cloud Is Overkill
Not everything needs AWS or GCP. Simpler platforms are often better for small projects and learning.
