What is Cloud Computing? How does cloud computing work?

Let’s say you are an executive of a large corporation. Your particular responsibilities include making sure all of your employees have the proper hardware and software they need to do their jobs. Every time you hire a new employee, you have to buy more software or make sure your current software license allows another user.

Instead of installing a software package for each computer, you would only have to load one application. The application would allow workers to connect to a web-based service that hosts all the programs that the user would need for their work. It’s called cloud computing, and it has come to change the entire computing industry.

Cloud Computing

What is Cloud Computing: –

Cloud Computing is a general term that applies to all processes and services hosted in the cloud through the Internet. It is a system that allows offering computing services through a network, which is generally the Internet.

In a simple way, we can say that cloud computing is a technology that allows access to software, file storage and data processing through the Internet. This is an alternative option to execution in situ on the personal computer or well local server. In the cloud model, it is not necessary to install applications locally on computers.

What is Cloud Computing used for?

In Cloud Computing, the hardware and software are provided as a service from another company over the Internet. Usually this all process happens in a completely transparent way. This new term provides multiple benefits and advantages for all types of companies and end-users.

How does Cloud Computing work?

It uses a network layer to connect user devices, such as computers, mobiles, laptops, to centralized resources in the data centre.

Before this cloud computing technology existed, the execution of the software by companies that offered this service was only possible if they could also pay for the maintenance of the server infrastructure.

In addition to this, traditional software needed a complete team of IT professionals, internal or external, to manage all the possible failures, updates that this type of systems entails.

The term cloud computing is free from all these drawbacks, and these requirements have been left behind.             [See More]

Cloud Computing Categories: –

These services that we can run or host in the cloud, through cloud computing, are divided into 3 categories:

1)   Software as a service (SaaS) model: –

This Software focuses on simplifying access to the software application for the user through a browser or program interface. With this model, the latent network, operational system, and resources go behind the scenes. This is a very common application in cloud computing. it is estimated that 59% of the total workloads in the cloud have been Software as a Service until 2018.

2)    PaaS Platform as a Service Model: –

This system facilitates the construction of applications through the tools and utilities offered by said system.

This model can take advantage of cloud computing while maintaining the freedom to develop custom software applications. Users can access PaaS in the same way as Software as a Service. The distributor is responsible for the maintenance of the operational system, the network, the servers and the security.

3)     Infrastructure as a Service IaaS Model: –

The company has absolute control over the cloud, therefore you must configure the machines, choose the memory and processor capacity. It is the most personalized and tailored solution of the company since it only contracts the storage capacity and the raw process.

It goes one step further in abstraction, giving organizations the ability to leverage server resources. Further it leftover management of the platform and software is the responsibility of the company. That leaves more capacity without concern with hardware requirements.

The transformative power of Cloud Computing: –

Each and every one of these capabilities provides and facilitates software applications and solutions in many areas. By crossing the barrier of technical expertise required to configure and sustain the infrastructure, companies can afford a safe, reliable and tailored alternative option.

 

Characteristics: –

There are three distinct characteristics that differentiate it from traditional web hosting:

1) Works on demand, usually by the minute or hour.
2) It is flexible: a user can have as much or as little service as he wants at any given time.
3) The service is fully managed by the provider (the consumer, client or company does not need anything more than a personal computer and Internet access).
4) Innovations in virtualization and distributed computing, as well as having better access to high-speed Internet.   5) Companies have increased interest in cloud computing, due to its many advantages, and savings in money and time.
