Cloud computing is a model of service delivery in which computing resources and software services are delivered to users via the Internet rather than a hardwired local area network (LAN). It enables the users to provide these products and services only once, regardless of how many clients they have.
The general concept of cloud computing is Supplying hosted services through the internet. Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) are the three primary categories or kinds of cloud computing under which these services fall. In other words, the on-demand availability of computer system resources, in particular data storage and computational power, without direct active administration by the user, is essentially what we call cloud computing. Large clouds frequently divide their services across several sites, each of which is a data center.

Basic & Easy Concept: Cloud Computing 101
The hardware and software elements necessary for a computing model’s correct execution are included in cloud services. Utility computing and on-demand computing are other terms for cloud computing. So do not get confused when using these terms interchangeably.
The cloud symbol, which is frequently used to symbolize the internet in flowcharts and diagrams, served as the inspiration for the name cloud computing.
Therefore, it is important to start by comprehending that cloud computing is nothing more than the delivery of services over the cloud. The next step is to comprehend the different sorts of clouds and the services they may offer. A cloud can be either public or private. Anyone online can purchase services from a public cloud. With specific access and authorization settings, a private cloud is a proprietary network or data center that offers hosted services to a small group of users. Cloud computing’s objective, whether it’s private or public, is to offer simple, customizable access to computer resources and IT operations.
Example Of Cloud Computing
Cloud computing is the foundation of a huge variety of services. This ranges from services that let big businesses host all of their data and operate all of their apps in the cloud to consumer services like Gmail or the cloud backup of the images on your smartphone. For instance, Netflix uses cloud computing services to power both its video streaming platform and other internal business processes.
Basic To Intermediate Concept – Knowing How Cloud Computing Works
Recognize that internet connectivity is a must for cloud computing. The front end, which consists of the connecting user’s device, computer, connection, and cloud software products, and the back end, which consists of datasets, servers, and computers, are connected via an internet network connection. The back end serves as a repository, holding the information that the front end may access. The contemporary concept thus addresses two issues. Only the front end of everything is visible to us. However, the backend must carry out its duties and serve as a connector and communicator for services to be delivered via the cloud.
Here, it’s crucial to realize that the controller exists at both the front end and the back end to manage if everything is working appropriately. A central server controls communications between the front and back ends. The central server uses protocols to speed up data sharing. To control communication between various client devices and cloud servers, the central server makes use of both software and middleware. Usually, each distinct application or task has its dedicated server.
Modern Technologies Involved In Cloud Computing
Virtualization and automation technologies vary in their potential and use cases. Virtualization helps in the consolidation of resources while automation uses robotics to help with certain solutions that couldn’t be accomplished manually.
Virtualization and automation are the key technologies behind cloud computing. They allow developers to shift between different operating systems, applications, and services with ease. These technologies make cloud hosting the most popular way of doing computing as it enables companies to easily shift between environments while also having an easier time scaling up their resources as they need them to grow their business.
