Cloud

In computer science, "Cloud" refers to cloud computing, which is the delivery of computing services over the internet. These services include servers, storage, databases, networking, software, analytics, and intelligence, allowing users to access and use resources remotely instead of relying on local servers or personal computers.Cloud computing provides flexibility, scalability, and cost-effectiveness by enabling users to pay only for the resources they actually use. It typically operates on a pay-as-you-go model, which can significantly reduce overall IT costs. Cloud services are commonly categorized into three models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each offering different levels of control and management.The "cloud" itself refers to the infrastructure and distributed resources managed by third-party providers in data centers, which can be accessed via the internet from anywhere in the world. This abstraction allows users to focus on using the software or services rather than managing the physical hardware involved. The flexibility of cloud computing has transformed how organizations handle data storage, application development, and resource management.
