A cloud proxy is a proxy server that runs on cloud infrastructure - AWS, Google Cloud, Azure and similar - instead of on your own hardware or a home connection. Your traffic is relayed through it, so the sites you visit see the proxy's IP address rather than yours. People use them for privacy, for checking how a site looks from another country, for ad verification, and for web scraping.
CloudProxy once sold its own on-demand cloud proxy service. That service has been retired; today the site is free tools and independent guides.
