## about this topic
Cloud computing is the model that turned infrastructure from a hardware investment into an on-demand service — and today it underpins practically every modern application. This hub gathers the CodeCrush articles on cloud and infrastructure: guides to the major platforms (AWS, Google Cloud, Azure), concepts such as serverless, containers and edge computing, and the networking fundamentals every developer should command — from latency and packets to DNS and CDNs. The goal is to help you understand not only how to use managed services, but what happens underneath them, so you can make better architecture and cost decisions on real projects.
