About Cloud Computing

 A physical site called a data center houses a common pool of computer resources (such as hardware, software, and services like servers and internet storage). Your cloud service providers have data centers all around the world.

Cloud computing is a methodology for providing on-demand network access to a shared pool of programmable computing resources that can be quickly supplied and released with no administration effort or service provider contact.
Cloud computing is an internet-based computing model in which several network connections and computer systems are used to provide online services. Users at a distance who have access to the internet can readily access the cloud and its services, and these services and information can be shared among several computers and users if they are all linked.

Types of Clouds

The four types of access to the cloud are public, private, hybrid, and community:

(a) Public Cloud: The public cloud makes it possible for anybody to access systems and services. Because of its openness, the public cloud may be less secure. The public cloud is one in which cloud infrastructure services are made available through the internet to the public or large industrial groups. The infrastructure in this cloud model is owned by the company that delivers the cloud service, not by the consumer.
Example: Microsoft Azure, Google App Engine

(b) Private Cloud: A private cloud is one in which cloud infrastructure is set aside for a single organization’s exclusive use. Organizations, third parties, or a mixture of both own, manage and operate it. In this architecture, the cloud infrastructure is provisioned on the organization’s premises but hosted in a third-party data center. Organizations will benefit from the private cloud over public cloud since it gives them more flexibility and control over cloud resources. Example: E-bay

(c) Hybrid Cloud: Hybrid cloud, as the name implies, is a blend of different cloud models, such as public cloud, private cloud, and community cloud. This model utilizes all the models that are a component of it. As a result, it will combine scalability, economic efficiency, and data security into a single model. The complexity of creating such a storage solution is a downside of this strategy.

(d) Community Cloud: The community cloud model distributes cloud infrastructure among numerous organizations to support a specific community with shared issues. Cloud infrastructure is delivered on-premises or at a third-party data center in this manner. Participating organizations or a third party manage this.
