In such a model, users access services based on their requirements without regard to where the services are hosted. This model has been referred to as utility computing, or recently as Cloud computing . The latter term denotes the infrastructure as a "Cloud" from which businesses and users ...
For example, a single hardware server can be divided into multiplevirtual servers. Virtualization enables cloud providers to make maximum use of their data center resources. Cloud computing services Infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), software-as-a-service (SaaS) and...
Types of cloud services: IaaS, PaaS, serverless, and SaaS Most cloud computing services fall into four broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). These are sometimes called the cloud computing "stack" ...
Cloud computing is the provision of computing resources via the Internet so that customers can access products and services hosted on remote servers, rather than on their own internal systems.
