Why do we need to understand cloud computing.

Cloud computing is called this because the information accessed is located in a remote location in the cloud or virtual space. Companies that provide cloud services allow users to store files and applications on remote servers and access all data through the Internet. This means that users do not need to be in a specific location to access it, allowing them to work remotely.

Using cloud technology, there is no need to manage files on local storage devices, and cloud computing can save files over the Internet. Cloud computing is divided into many types; deployment models and service models
cloud computing types are:

deployment models are divided into the following three types:
public cloud
private cloud and
hybrid cloud
public cloud

public cloud can be connected through the Internet and The Internet is available to the public. The public cloud service providers
owned by the cloud provider
Amazon Web Services (AWS), Microsoft Azure, IBM’s Blue Cloud and Sun Cloud

Private Cloud
In a private cloud, the infrastructure is only operated by a single organization. It can be managed by an organization or a third party, and can be implemented internally or internally. 4,444 private cloud service providers include;
Amazon Web Services (AWS) and VMware.

Hybrid Cloud
Hybrid Cloud includes public functions and public functions.
Federal agencies use private clouds to process sensitive information and use public clouds to share data sets with the public or other government departments.
Service model

Service model:
Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software Service (SaaS)
IaaS is a cloud service that provides a basic computing infrastructure, whose services can be provided in a pay-on-demand model. IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Compute Engine. IT administrators often use IaaS in their daily activities.
PaaS provides a cloud platform and runtime environment for developing, testing, and managing applications. PaaS enables software developers to deploy applications without all the related infrastructure. It is used mainly by software developers.
In SaaS, cloud providers host and manage software applications on a pay-as-you-go pricing model. With SaaS, all software and hardware are provided and managed by the vendor, so there is no need to maintain anything. For use by end customers.
Amazon Web Services (AWS)
