Cloud computing is a pay-as-you-go model that provides available, convenient, on-demand network access to a configurable shared pool of computing resources (including networks, servers, storage, applications, services) that can be made available quickly with minimal administrative effort or interaction with service providers.
Cloud computing has five basic characteristics: on-demand self-service, extensive network access, resource pooling, rapid resiliency, and service metering. There are three service models for cloud computing, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). In addition, there are four deployment models for cloud computing: private cloud, community cloud, public cloud, and hybrid cloud.
The five basic characteristics of cloud computing include:
1、On-demand self-service: Users can obtain computing resources on demand without manual intervention.
2、Extensive network access: The service is provided over the network, supporting access through a variety of devices (such as mobile phones, tablets, laptops) using standard mechanisms.
3、Resource pooling: Computing resources of a cloud service provider are pooled for use by multiple users, often unaware of the specific physical location.
4、Fast resilience: Resources can be rapidly expanded or scaled back in response to demand changes, and for users, resources seem to be unlimited.
5、Measurable services: The cloud system automatically controls and optimizes the use of resources, using a measurement method to ensure that the allocated resources match the used resources.
