Cloud computing is a transformative technology that allows businesses and individuals to access computing resources—such as servers, storage, databases, networking, software, and more—over the internet. This model eliminates the need to own and maintain physical hardware, enabling flexible scalability and reduced costs. Cloud computing is typically offered in three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
IaaS provides virtualized computing infrastructure over the internet, allowing users to run operating systems and applications without having to purchase or manage physical servers. PaaS provides a platform that allows developers to build, test, and deploy applications more efficiently. SaaS offers complete software solutions that are managed by a service provider and accessed via a web browser.
Cloud computing brings numerous benefits such as elasticity, where businesses can scale resources up or down based on demand; cost efficiency, since users pay only for what they use; high availability and reliability through redundant infrastructure; and easier collaboration, as cloud services are accessible from anywhere.
Security, compliance, and data privacy remain critical considerations. Modern cloud providers offer advanced security measures such as encryption, access control, and regular audits. Cloud computing continues to evolve with innovations in edge computing, hybrid cloud, AI integration, and green computing.
