Cloud providers are companies that offer various computing services over the internet, enabling users to access and manage resources such as storage, processing power, and applications without the need for physical infrastructure. These services are typically categorized into three main models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Major cloud providers, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), cater to diverse needs ranging from data storage to machine learning capabilities. As businesses increasingly adopt cloud solutions, understanding the offerings of different providers becomes essential for optimizing operations and costs.
