Cloud computing is a technology that delivers computing services—such as servers, storage, databases, networking, software, and analytics—over the internet. Instead of owning their own computing infrastructure or data centers, companies and individuals can rent access to these services from cloud providers.
1. Definition of Cloud Computing
Cloud computing allows users to access and store data and programs over the internet. It provides the ability to store large amounts of data without the need for physical infrastructure.
2. Key Models of Cloud Computing
There are three main cloud computing models:
– **Infrastructure as a Service (IaaS)**: Provides virtualized computing resources over the internet.
– **Platform as a Service (PaaS)**: Provides a platform for developers to build applications without worrying about the underlying infrastructure.
– **Software as a Service (SaaS)**: Offers software applications over the internet on a subscription basis.
3. Benefits of Cloud Computing
– Cost savings by eliminating the need for physical infrastructure.
– On-demand access to resources, which are scalable.
– Accessibility from any location with an internet connection.
Cloud computing has revolutionized how businesses operate, enabling them to scale efficiently and focus more on innovation than infrastructure management.
