Cloud computing refers to the delivery of computing services, including storage, processing power, and software, over the internet. Instead of owning and maintaining physical servers and infrastructure, users can access and use computing resources on a pay-as-you-go basis from a cloud service provider. This model offers several advantages, including scalability, flexibility, cost-effectiveness, and the ability to access resources from anywhere with an internet connection.Services are available over the network and can be accessed by various devices, such as laptops, smartphones, and tablets.Resources can be quickly scaled up or down based on demand. This allows users to adapt to changing workloads without investing in additional infrastructure.Popular cloud service providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and others. Organizations of all sizes use cloud computing to reduce costs, increase agility, and focus on their core business activities.
