Cloud Computing

Cloud computing is a transformative influence that has revolutionized how businesses and individuals access and oversee computing resources. At its core, cloud computing involves the delivery of an array of services�ranging from computing power and storage to databases, networking, software, analytics, and intelligence�over the internet, or "the cloud." This model offers unparalleled advantages, including faster innovation, flexible resource allocation, and economies of scale. Notably, it liberates organizations from the burden of investing in and maintaining physical hardware and infrastructure, enabling them to concentrate on their core business activities.
Several defining characteristics encapsulate the essence of cloud computing. On-demand self-service allows users to effortlessly provision and manage computing resources as needed, obviating the necessity for human intervention from service providers. Broad network access ensures that cloud services are accessible from an assortment of devices, such as laptops, smart phones, and tablets, enhancing flexibility and user convenience. Resource pooling involves the aggregation of computing resources to serve multiple customers, with dynamic allocation and reallocation based on demand. Rapid elasticity allows for the automatic scaling up or down of cloud resources to accommodate changing workloads, ensuring optimal performance and operational efficiency. The measured service characteristic entails the metering of cloud computing resources, ensuring that users pay only for the resources they consume, promoting cost-effective and efficient resource utilization.
Cloud computing is typically classified into three main service models. Infrastructure as a Service (IaaS) provides virtualized computing resources over the Internet, including virtual machines, storage, and networking. Users retain control over the operating system and applications but are relieved from managing the underlying infrastructure. Platform as a Se
