VPC
A VPC (Virtual Private Cloud) is like having a private, secure section of the internet just for a company's use. Think of it as a virtual version of a traditional private computer network, but hosted in the cloud. Companies use VPCs to keep their online resources, like websites and databases, safe and separated from others. It's similar to having a private office building with security controls, but in the digital world. Major cloud providers like Amazon (AWS), Microsoft (Azure), and Google all offer their own versions of VPCs, though they might use slightly different names. When you see this term in resumes, it usually means the person has experience setting up and managing these secure cloud environments.
