According to NIST, cloud computing is
“a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rap idly provisioned and released with minimal management effort or service provider interaction.”
the five essential cloud characteristics that truly define the technology:
on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.
On-demand self-service
allows users to provision resources automatically without requiring human intervention from the service provider.
Broad network access
means that cloud services are available over the network and accessed through standard mechanisms, enabling usage across various devices.
Resource pooling
refers to the provider's ability to serve multiple customers with dynamic allocation of resources, sharing them among a large number of users.
Rapid elasticity
is the capability of a cloud system to automatically scale resources up or down as needed to accommodate varying demand.
Measured service
is a feature that allows cloud services to be monitored, controlled, and reported, providing transparency for both the provider and the consumer.
The “as a ser vice” technologies
refers to service delivery models such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), where resources are provided over the internet and billed on usage.
r to provision processing, storage, networks, and other fundamental computing resources. The customer is then able to deploy and run arbitrary software, which can include operating systems and applications. The customer does not manage or control the underlying physical infrastructure but has con trol over operating systems, storage, and deployed applications. The customer might also have limited control of select networking components such as host firewalls. Notice that this level of control is much greater than is found with PaaS and SaaS models
