Cloud computing is a technology that enables on-demand access to computing resources over the internet, eliminating the need for local servers and physical infrastructure. It offers flexibility, scalability, and cost-efficiency by allowing users to rent processing power, storage, and software applications on a pay-as-you-go basis. This model supports various services, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), catering to diverse business needs. Cloud computing enhances collaboration, disaster recovery, and remote work capabilities, making it a critical component of modern IT strategies.
