Cloud Computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) rather than relying on local servers or personal devices. This approach allows businesses and individuals to access a wide range of technology resources on-demand, eliminating the need for significant upfront hardware or infrastructure investments. By leveraging cloud computing, organizations can scale resources dynamically based on their needs, ensuring flexibility and cost-efficiency.
Cloud computing operates through various service models: Infrastructure as a Service (IaaS) provides virtualized computing resources like servers and storage, Platform as a Service (PaaS) offers platforms for developing and deploying applications without managing underlying infrastructure, and Software as a Service (SaaS) delivers ready-to-use applications over the internet. Deployment models include Public Cloud, Private Cloud, Hybrid Cloud, and Multi-Cloud, catering to diverse business requirements and security needs. The cloud also enables collaboration, remote access, and faster innovation by allowing teams to work from anywhere and utilize advanced tools and analytics without maintaining complex IT infrastructure. Its scalability, reliability, and pay-as-you-go pricing make it an essential component of modern IT strategies, driving digital transformation across industries such as healthcare, finance, e-commerce, and education.
