Cloud computing refers to the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. It involves the 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. This model enables access to applications and data from anywhere with an internet connection, removing the need for local hardware and software installations, leading to cost savings and increased efficiency. It encompasses various service models like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It also includes deployment models such as public, private, and hybrid clouds.
Cloud-computing meaning with examples
- A small business can leverage cloud computing by using SaaS platforms for customer relationship management (CRM), eliminating the need for expensive server infrastructure and IT staff. This allows them to focus resources on core business activities and scale their software capabilities as the company grows, paying only for the resources they consume. This agility boosts their competitiveness in the market.
- A university researcher utilizes cloud computing for big data analysis, accessing massive datasets and powerful computational resources hosted on remote servers. This simplifies the processing of large volumes of data and enables complex simulations, enhancing the speed and quality of scientific discovery. It also eliminates the need for local on-premise computing.
- A software developer uses cloud computing to create and deploy web applications using a PaaS environment. They can code, test, and launch their applications without worrying about server management, operating system configuration, or networking. This accelerated the development lifecycle, allowing the development team to get the application out in the market faster.
- A multinational corporation uses a hybrid cloud model to balance the need for security, control, and scalability. Some sensitive data and critical applications reside on a private cloud infrastructure, while less-sensitive workloads are deployed on a public cloud. This approach allows for cost optimization and risk mitigation while maintaining control over the data.
