Cloud Computing
Cloud computing is the on-demand delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet ('the cloud') to offer faster innovation, flexible resources, and economies of scale. It enables users to access and use shared computing resources without owning or managing physical infrastructure, typically through a pay-as-you-go pricing model. This model supports scalability, reliability, and cost-efficiency for businesses and developers.
Developers should learn cloud computing to build scalable, resilient, and cost-effective applications that can handle variable workloads and global user bases. It is essential for modern software development, enabling deployment of microservices, serverless architectures, and big data processing without upfront infrastructure investment. Use cases include web hosting, data analytics, machine learning, and disaster recovery solutions.
