Traffic journey from Client to Backend in Google Cloud

Securing cloud applications begins with understanding how request traffic moves through Google Cloud’s infrastructure. From the moment a request leaves the client machine to the moment it reaches backend services, every component along the path contributes to performance, resilience, and security. When I first explored this flow, I found myself overwhelmed by the number of services involved — and unsure which ones were essential, optional, or security‑critical. What happens at each hop? How do these services interact? And which layers truly matter when building a secure, compliant, and scalable cloud application in Google Cloud? This post breaks down those questions using a simple, intuitive analogy: an airport journey. In this model, the client request becomes a passenger navigating terminals, security checkpoints, and routing desks — eventually boarding the airplane (backend service) where your application runs. In the next post, I’ll flip the perspective and walk through the return ...
