What Is Cloud Computing?


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

We can say that cloud computing or cloud computing is a technology that allows access to Software, file storage, and data processing through the Internet, being an alternative option to execution in situ on the personal computer or local server.

There is no need to install applications locally on computers in the cloud model.

What Is Cloud Computing For?

In Cloud Computing or cloud computing, hardware and Software are provided as a service from another company through the Internet, usually in a completely transparent way. This new term offers multiple benefits and advantages for all companies and end-users.

How Does Cloud Computing Work?

Cloud Computing uses a network layer to connect user devices, such as computers, mobile phones, laptops, to centralized resources in the data center.

Before this cloud computing technology existed, the execution of Software by the 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 system entails.

The term cloud computing or cloud computing is free from all those drawbacks, and these requirements have been left behind.

Cloud Computing Categories

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

Software As Service (SaaS)

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

Platform As A Service PaaS 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 the Software’s tailored applications. Users can access PaaS in the same way with Software as a Service. The distributor is responsible for maintaining the operational system, the network, the servers, and the security.

Infrastructure As A Service IaaS Model

The company has absolute control over the Cloud. Therefore, it must configure the machines to choose the memory and processor capacity. It is the company’s most personalized and customized solution since it only contracts the storage capacity and the natural process.

It goes a step further in abstraction, providing organizations with the ability to leverage server resources while leaving the rest of the platform and software management the company’s responsibility. That leaves more capacity without worrying about hardware requirements.

The Transformative Power of Cloud Computing

These capabilities provide and facilitate software solutions and applications in many fields. By crossing the barrier of the technical expertise required to configure and sustain the infrastructure, companies can afford a secure, reliable, and tailored alternative option.

Cloud Computing has three distinct features that set it apart from traditional web hosting:

  • Work on demand, usually by the minute or hour
  • It is flexible: a user can have as much or as little service as they want at any given time.
  • The provider fully manages the service (the consumer, client, or company does not need anything more than a personal computer and Internet access).

Innovations in virtualization and distributed computing and the availability of better high-speed Internet access today have accelerated and notably increased the interest in cloud computing due to its multiple advantages and savings in money and time for the companies.

Types Of Cloud Computing According To Privacy

A cloud can be private or public.

Public Cloud

In this Cloud Computing system, the provider sells services to anyone on the Internet. That is, it provides its resources in a relaxed way. ( Amazon Web Services is currently the largest public cloud provider, Azure or Google Engine .)

In this case, a third party is hired, in charge of the technical and operational part. There is no control over which other clients are hosted on the same infrastructures, which implies trust in the provider.

Private Cloud

A private cloud is a proprietary network or data center that provides hosted services to a limited number of people. Generally, companies, large organizations, and entities opt ​​for this type of storage system.

Hybrid Cloud

These solutions have a lot of potential and are in full swing, as they allow you to contract and expand the service according to your needs.

Private or public, the goal of cloud computing is to provide easy and scalable access to computing resources and IT services.

What Are The Advantages Of Cloud Computing?

The world of Software is constantly changing and evolving. When Salesforce was created in 1999, it was the first business service to offer business applications in one place, which came to be called cloud computing. Salesforce has been the benchmark and forerunner in this service for small, medium, and large companies.

In other words, the definition of cloud computing is to offer services through the large-scale connectivity of the Internet. Cloud computing makes it easier for everyone to access software resources at an international level since it is a software application that serves different service clients.

Multilocation is what differentiates cloud computing from older application service vendor models. Small businesses now also have access to advanced technology in a scalable way.

Cloud computing offers individuals and all types of businesses endless well-maintained, secure, easily accessible, and on-demand computing resources such as servers, data storage, and application solutions.

All this provides:

  • Businesses and companies with greater flexibility.
  • Being able to access their data anywhere and at any time.
  • Being essential for companies with offices all over the world and with different work environments.

With a minimum of administration, every element of cloud computing software can be sized on-demand. All you need is a good internet connection.

Seven Advantages Of Cloud Computing

Flexibility and Scalability: Cloud-based services can meet increased demand instantly and are suitable for all types of businesses.

Restore – Cloud Computing vendors handle restore issues more efficiently.

Automatic Software Updates: Cloud Computing vendors are responsible for maintaining the server and its Software, including security updates.

Multi Sites and multi-location: Employees only need access to the Internet to work from anywhere.

Collaborative Work: Every employee can share applications.

Security: The data stored in the Cloud can be accessed from anywhere, regardless of losing one or more devices.

Sustainability and Ecology: Cloud computing uses only the space required on the server, reducing the use of redundant materials.

Some Disadvantages of Cloud Computing

Connectivity: the company must have guaranteed Internet connectivity. It should not depend on a single Internet connection because every connection is susceptible to failure, and if it fails, the company will not be able to work with the Software.
