Understanding the Basics of Cloud Computing - Why is Cloud Computing So Important in Today's World?

Overview
In the age of the Internet, the age of information technology, the amount of data and information available on the Internet increases dramatically and accumulate files within public and private computers. 

A large segment of society needs to access that information in a system that allows them to access it at any time, starting with individuals seeking information including educational institutions (schools, institutes, universities, etc.).

As storage costs continue to rise, organizations face the challenges of data retrieval and backup. This shows the importance of cloud computing, which aims to protect and manage data effectively, efficiently and easily.

Cloud computing is a new solution for managing and storing different data and information. People can access applications from anywhere, anytime and from any Internet-connected device.



What is Cloud Computing?

Cloud computing is a technology that relies on transferring the processing and storage space of a computer to what is termed the "cloud". 

The cloud is a server that is accessed through the Internet and thus Information Technology (IT) programs are transformed from products to services.

Cloud computing can also be defined as a computerized method in which a massive amount of IT-related competencies are provided as an online service to double the number of outbound customers. 
It can be briefly defined as an emerging technical model whereby applications, data, and IT resources are provided as services to users over the Internet.

“Cloud Computing” is a modern concept in the world of information technology to provide computer technologies when needed as services at any time, using various types of computers or smartphones, safely and at the lowest cost. 
It is Internet-based computing, whereby a large number of shared computing resources such as servers, software applications, and storage applications can be accessed via computers or other devices over the Internet.

The cloud computing model is also a means of providing access to a common set of customizable computing resources (such as networks, servers, storage, applications, and services) that can be provided and deployed with minimal effort when managed and without the need to interact with the service provider.

Basic Components of Cloud Computing

To deal with cloud computing, the following elements, or what can be called cloud computing components are:

A. User/customer: The user or customer who will use this technology and benefit from its services through the use of his personal computer or mobile phone.

B. Platforms: Platforms are the donors of this service by providing giant servers in their storage capacities and the speed of data processing such as Google and Apple.

C. Infrastructure: The infrastructure of the cloud - infrastructure as a service (IaaS), which is reliable in providing the service, including the availability of personal computers and the Internet and storage space for information.

D. Applications: These are the software applications that can be operated by the user in the cloud, including word processing, presentation, spreadsheet and information transfer and sharing services.

E. Service: A service used by the cloud. The subject is more related to the term Software as a Service (SaaS), which is the process of converting computer products into services.



The Fundamental Elements of Cloud Computing

In cloud computing we need five main elements:

1. Personal Computer (PC): Any device with medium or under medium capabilities is enough only to connect to the Internet.

2. Operating System (OS): Any system that allows access to the Internet. This feature is available in almost all existing operating systems.

3. Internet Browser: There is no requirement on the type of browser used in cloud computing as long as the large sites are compatible with it, it is suitable for the use of cloud computing without any obstacles.

4. Availability of Internet connection: Internet connection, in this case, is preferable to be high speed, it is the link between the user and all his data and all the programs he uses.

5. Cloud Computing Provider: Looks like a web hosting provider, but has additional features that allow both developers and users to use the resources available on the servers more efficiently.

Cloud Computing Patterns
Cloud computing applications can be described in two orthogonal ways:
 (1) Through the competencies or abilities, they provide.
 (2) Through those who have access to resources.



Types of Cloud Computing

After learning about the meaning of cloud computing and taking some examples of services it offers, you should now know the types of cloud computing, and that can also be summarized in three types:


Public Cloud Computing

Public cloud computing is an infrastructure that provides all computing applications and resources but a group of customers and applications are mixed on the servers.


Private Cloud Computing

Private cloud computing is also an infrastructure but leased to a single person or an institution so that it works for him and at his full disposal in the data and security and the quality and efficiency of the service.


Hybrid Cloud Computing

Hybrid cloud computing is an infrastructure that combines public and private cloud models so that each can be provided.


Cloud Computing Services

Cloud computing can be summed up in three main services that represent all the various cloud computing services.

1. Software as a service (SaaS)
3. Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)

5 Major Characteristics of Cloud Computing
The most important characteristics of cloud computing may include:

1. On-Demand Self-Service: User can provide unilateral computing capabilities when needed automatically without having to interact with each service provider.

2. Wide Area Network (WAN): Capabilities available over the network and accessed through modular mechanisms that enhance use through customers' platforms with varying characteristics (e.g. mobile phones, tablets, laptops, workstations).

3. Resource Pooling: Cloud Service Provider Resources are grouped to serve multiple users using a multi-tenant model, with different physical and virtual resources that are effectively assigned and reassigned as requested by users. 

There is a sense of site autonomy so that the user usually has no control or knowledge of the actual location of the resources provided but may be able to locate the site at a higher level of meaning abstraction (such as state, state, or data centers). 
Examples of resources include storage, processing, memory, and network bandwidth.

4. Rapid flexibility: In some cases, capabilities can be provided and deployed automatically, so that there is an internal and external improvement commensurate with demand. 
For the user, the possibilities available are often unlimited and can be accessed at any time.

5. Cloud-based service: Cloud systems automatically control resources and optimize their use by utilizing the measurement of capabilities at a certain level of meaning abstraction, which is appropriate for the type of service (eg storage, processing, bandwidth, and active user records). 
Resource usage can be monitored and controlled, and a report written about it, providing transparency for both the service provider and the user.



Why is Cloud Computing So Important in Today's World?

Cloud computing environment enables users to transform their energies into creating interactive solutions for dealing with office work, files, movies, audio files… instead of routine hardware maintenance.

Cloud computing also reduces the chances of file loss in the devices and gives the user great possibilities of means to work and collaborate anywhere and anytime and from any device.
In addition, it improves the work and increases the likelihood of completion of the work. 

The IT cloud for individuals or organizations facilitates participation and collaboration among colleagues in a flexible and infinite way and without temporal or spatial constraints.

Cloud computing also has the advantage that PCs do not have, namely collaboration. Resources in the cloud can be accessed and shared from anywhere, provided you have an Internet connection. 

Cloud computing also has the advantage that PCs do not have, namely collaboration. Resources in the cloud can be accessed and shared from anywhere, provided you have an Internet connection. 

Cloud computing is also easy to use as many educational institutions around the world have confirmed that cloud computing is a very attractive and integrated system for educational use.


Top 5 Cloud Service Providers Companies in the World

There are many companies that have a great impact on providing cloud computing services over the Internet. These companies include:

Microsoft Corporation: Microsoft Azure offers all of the services that can be delivered through cloud computing, and it ranks first in terms of the largest companies in this field.

Amazon: This is known as Amazon Web Services (AWS). This company has achieved significant financial returns in one year.

Google Cloud Platform (GCP): The Google Cloud Platform is a suite of cloud computing services that allows you to build, deploy, and scale applications, websites, and services on the same infrastructure that Google uses internally for its end-user products.

International Business Machines Corporation (IBM): IBM has transferred its vast software expertise to cloud computing.
