Google Cloud Platform (GCP) is a collection of cloud computing services offered by Google that runs on the same infrastructure that Google uses internally for its end-user products, such as Google Search and YouTube. GCP offers a variety of services including computing, storage, networking, big data, machine learning, and the internet of things (IoT). These services can be accessed and controlled through a web-based console, command-line tools, or APIs. GCP is designed to help developers and businesses scale and grow their applications, websites, and services.
