Your cloud resources don't sit naked on the open internet — they live inside a private network you control. This chapter explains what that network is, how it connects to the outside world, how DNS turns names into addresses, and how load balancers and CDNs keep busy services fast and resilient.

Every online service — a shop's website, a company's internal tool, a streaming app — is built on a network. The cloud doesn't change that: when you rent cloud resources, they communicate over networks, just like computers in an office. What the cloud adds is control. You get your own private, fenced-off slice of the network, and you decide exactly what's visible to the outside world and what stays hidden.
Five topics cover the ground. First, the private network itself and why isolation matters. Then the standard ways to connect it to other places — the internet, your office, another network. Then DNS, the system that turns the names we remember into the numbers machines need. Then load balancers and CDNs, the two tools that handle heavy traffic. And finally, a full alignment of all the networking names across AWS, Google Cloud, and Azure.
