Cloud computing is the use of computer resources that are always available, including storage, processing, and data power, under the direct, active control of the user.


Public clouds                                                

Public clouds are computing environments that commonly use IT technology that is not owned by the end user.Alibaba Cloud, Amazon’s Web Services (AWS), Google, IBM Cloud, and Azure are a few of the biggest public cloud service providers.

Public clouds in the past have always operated off-site, but history’s providers of public clouds have begun to provide cloud services on clients’ on-site data centers.

When the environment are divided and dispersed to several tenants, all clouds became public clouds. since some cloud service companies (like the Massachusetts Open Cloud) permit free cloud usage by their clients. It is also possible to abstract and resell the bare-metal IT equipment used by cloud service providers as IaaS, or to build and sell a cloud platform as PaaS.

Private clouds

Individual clouds

A cloud infrastructure is an entirely dedicated cloud system that is often located behind the firewall of the end user or company in question. Become private clould, for an access to a single individual.

Sometimes, private clouds are no longer required. The regulations controlling location or ownership are no longer applicable as firms build private clouds in the off, rented data centers run by vendors. This has also caused the creation of numerous private cloud subtypes, including:

Supervised private clouds

A third-party provider deploys, configures, and manages a cloud solution that customers build and utilize. Betterment of the quality of work and management.

Particular clouds

a cloud inside of a cloud. A dedicated cloud can be found on either a private or public cloud, such as Red Hat OpenShift® Dedicated.

Hybrid clouds

An IT environment that consists of many environments that appear to be linked by LANs, WANs, VPNs, and/or APIs to create a single, unified environment is known as a hybrid cloud.

Characteristics are also vary. At least single private cloud and one public cloud are present. Two or even more private clouds are also present.

• At least two public clouds

• A virtual or bare-metal setup coupled with at most one public or private cloud

But, when apps may move in and out of many distinct—yet connected—environments, every IT system turns into a hybrid cloud. Such environments must be sourced through consolidated sources in some cases.


Several cloud services from different private or public cloud vendors make up a multicloud architecture. While not all multiclouds are hybrids clouds, all cloud services are multiclouds. Hybrid clouds are created when multiple clouds are connected via connectivity or management.

An environment with many clouds may exist accidentally or on design (to better protect sensitive data or provide redundant storage for better disaster recovery) . In any case, businesses who want to enhance safety and efficiency through a broadened portfolio of environments are increasingly likely to have numerous clouds.


Cloud or online services:

Cloud services are facilities, platforms, or programs that are hosted by outside suppliers and made online accessible to users. The three main subcategories of as-a-Service solutions are IaaS, PaaS, and SaaS. Each one facilitates the transport of user data back from the front-end users to the servers of the cloud storage provider, but they vary in the functionality they give.


IaaS stands for a cloud service provider who uses an internet connection to handle your infrastructure, including the real equipment, networks, virtualization, and data storage. The user essentially rents the hardware and has access via an API or dashboard. While the provider handles any hardware, connectivity, hard disks, data storage, and servers, and is in charge of handling outages, repairs, and device issues, etc.


An independent cloud service company known as a PaaS provider provides and manages both the hardware and a software architecture, but the client is in control of the top-layer programs running on the platform and the data those apps depend on.

PaaS provides users with a shared cloud platform for app development and management (a crucial DevOps component) without their having to construct and maintain the infrastructure typically involved with the process. It is mainly for developers and programmers.


SaaS also eliminates the need for software to be installed locally on each user’s browser, expanding the possibilities for teams or groups to have access to the program. Users can connect to the cloud services via a panel or API, and updates, bug patches, and other routine software maintenance are handled for them. 

Cloud Services Types

Regardless of the service type, cloud computing services offer consumers a number of features, such as:

  • Email
  • Audio and video streaming; data analysis;
  • App development and testing; storage, backup,
  • And retrieval of data; and on-demand software delivery.

Cloud computing is being used by a wide range of industries, including large corporations, small businesses, charitable organizations, government entities, and even individual customers.

Cloud computing uses

It’s likely that public cloud is enabling all of these activities in the background if you use any internet service to send emails, edit documents, view tv or Movies, enjoy music, play online games, or save photos and other files.

Although though the initial services offered by cloud computing are just a decade old, a wide range of businesses, from small startups to multinational firms, government entities to non-profits, are already adopting the technology. 

With cloud computing from a cloud service today, the following are a few instances of what is possible:

Developing cloud-native applications:

Develop, launch, and grow applications—web, mobile, and API—quickly. Use cloud-native techniques and technologies, including DevOps, microservices architecture, Kubernetes, containers, and Kubernetes

Develop and test applications:

Use cloud technologies that can be readily scaled up or down to reduce the cost and time associated with application development.

Data storage, backup, and recovery:

By sending your information via the web to an offshore cloud storage solution that is available from any place and any device, you can safeguard it more affordably and on a large scale.

Data analysis:

Use the cloud to unify your data among departments, teams, and regions. To gain insights for wiser judgments, leverage cloud services like AI and machine learning.

Playback of audio and video:

Communicate with your audience wherever they are, whenever they use any device, with high-definition audio and video that is distributed worldwide

Integrate intelligence:

Use smart models to engage customers and offer insightful information from the collected data.

Prime advantages of cloud computing

Advantages are given below:


With cloud computing, there is no longer a need to invest in hardware, software, the infrastructure of on-site datacenters, including the server racks, round-the-clock electricity for electricity and cooling, and IT professionals to oversee the infrastructure. It quickly adds up.


Even massive amounts of computing capacity may be installed in seconds, typically with only some few mouse clicks, because to the self-service and on-demand nature of the bulk of cloud-based services. This gives businesses a lot of flexibility and lessens the workload associated with planning.

Worldwide scope:

One benefit of computing in the cloud is its elastic scaling’s adaptability. This refers to offering the proper level of IT capabilities at the proper time in a suitable location there in context of the internet, such as more  or less processing power, storage, and bandwidth.


Setting up gear, patching software, or other time-consuming IT managerial functions are typical requirements for on-site datacenters. Several of these duties are no longer necessary thanks to cloud computing, freeing up IT employees’ time to focus on more crucial business objectives.


A global network of secure datacenters that are regularly updated with the latest phones of swift and efficient computing equipment powers the major cloud computing services. As comparison to a single corporate center, this has a number of advantages, including lower network latency for apps and greater cost savings.


Due to the fact that data can be replicated at numerous redundant locations on the network of the cloud provider, cloud computing renders data backup, recovery plans, and continuity planning simpler and less expensive.


A wide range of rules, tools, and controls are provided by many cloud service providers, strengthening your overall security posture and defending your infrastructure, apps, and data from potential threats.
