Google Cloud is a suite of cloud computing services that runs on the same infrastructure used by Google internally for its products like Google Search and YouTube. It provides developers and enterprises with scalable, on-demand services for computing, storage, networking, big data, and machine learning over the internet. Customers can access Google Cloud on a pay-as-you-go basis and use it to build applications, store data, and manage complex workloads without having to purchase and maintain their own physical data centers.
