Cloud Computing
Cloud computing refers to the provision of IT resources and computing services, such as storage, databases, networks, operating systems, and software, via the Internet. These resources are made available in a flexible, scalable manner tailored to specific needs.
Functionality and Use
Cloud computing enables users to access IT resources over the internet without having to operate their own hardware. Users can access storage, software, or computing power as needed, which reduces costs and allows systems to be deployed more quickly.
Physical and virtual resources are pooled together and made accessible via a network. These resources can be flexibly accessed, metered, and scaled as needed according to the self-service principle.
It is used to reduce infrastructure costs, scale flexibly, and deploy applications efficiently. Depending on requirements, models such as IaaS, PaaS, and SaaS are available and form the basis of many modern digital applications.
Types
- Private cloud: Cloud infrastructure is operated exclusively for a single company.
- Public cloud: Services are provided by a single provider and shared by many users.
- Community cloud: Infrastructure is used by multiple organizations with shared interests.
- Hybrid cloud: A combination of multiple cloud environments connected to each other via interfaces.
Examples
- Companies store data in cloud services such as Google Drive or Dropbox
- Developers use cloud platforms to develop and run applications
- Streaming services deliver content via cloud infrastructure
- Companies operate their IT systems flexibly without their own servers
