Cloud Computing Characteristics and Types by Muhammad Yousuf Ali
The term cloud was used to refer to platforms for distributed computing as early as 1993, when Apple spin-off General Magic and AT&T used it in describing their (paired) Typescript and Personal Link technologies.
The cloud computing is the delivery of computing services it includes servers, storage, databases, networking, software, analytics, and intelligence over the internet. “The cloud” offers fastest, innovative, flexible resources to software houses, IT companies, academic institutions, students and general users. In this article explore answers of the following questions.

What is Cloud Computing?
Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user (Ray, 2018). Large clouds often have functions distributed over multiple locations, each of which is a data center (Ahmadreza, et al., 2020). Cloud computing relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users.
What are the Types of Cloud Computing?
There are four main types of cloud computing: private clouds, public clouds, hybrid clouds, and multiclouds.
Private cloud
Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally.
Public cloud
Cloud services are considered “public” when they are delivered over the public Internet, and they may be offered as a paid subscription, or free of charge(Rouse, 2014). Architecturally, there are few differences between public- and private-cloud services, but security concerns increase substantially when services (applications, storage, and other resources) are shared by multiple customers. Most public-cloud providers offer direct-connection services that allow customers to securely link their legacy data centers to their cloud-resident applications.
Hybird Cloud
Hybrid cloud is a composition of a public cloud and a private environment, such as a private cloud or on-premises resources, that remain distinct entities but are bound together, offering the benefits of multiple deployment models(The Data Center, 2012). Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. defines a hybrid cloud service as a cloud computing service that is composed of some combination of private, public and community cloud services, from different service providers.
Multi cloud
Multi-clouds are often confused with hybrid clouds. Multi clouds bring together multiple public clouds from different cloud service providers, whereas hybrid clouds integrate the features of public and private cloud environments.
What are the characteristics of cloud computing?
The National Institute of Standards and Technology‘s definition of cloud computing identifies “five essential characteristics”:
1. On-demand self-service.
A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.
2. Broad network access.
Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).
3. Resource pooling.
The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.
4. Rapid elasticity.
Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time.
5. Measured service.
Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
