Cloud providers are companies that offer various computing services over the internet, enabling businesses and individuals to access resources such as storage, processing power, and applications without the need for physical infrastructure. These services can be categorized into public, private, hybrid, and multicloud models, each catering to different needs and preferences. Major cloud providers like Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure dominate the market, providing scalable solutions that support a wide range of applications, from data storage to machine learning. Understanding cloud providers is essential for leveraging modern technology effectively.
