The cloud is a term used to describe a global network of servers, each with a unique function. The cloud is not a physical entity, but rather a vast network of remote servers around the world that are connected to function as a single ecosystem. In other words, it is the ability to access and store data over the internet. Files or programs are stored on cloud servers, rather than on a computer.

Instead of accessing files and data from a personal or local computer, access them online from any internet-connected device.

The three types of clouds that exist are:

• Public cloud: It is the public cloud that resources, such as servers and storage, are owned by a provider of these services. Furthermore, public cloud resources are shared among the different organizations that purchase the service. Security is weaker than in hybrid or private cloud services due to their structure.

The advantages of this cloud are its costs (customers pay for the storage space they need), its maintenance (the provider takes care of this), its almost unlimited scalability (different resources available), and its reliability (a large server network prevents problems).

• Private cloud: These services are offered to a limited number of users through corporate networks. In other words, in a private cloud, computing resources are only accessible by your organization, regardless of whether the infrastructure (data center) is on-premises or outsourced to a third party. Security is entirely up to the organization, which assumes the costs associated with its management.

Private clouds are typically used by government agencies, financial institutions, and any medium- to large-sized organization looking to increase control over their environment.

• Hybrid cloud: Combines both clouds, storing data in public or private clouds depending on needs. Public cloud computing resources can be leveraged when private cloud resources become insufficient due to seasonal reasons, or less sensitive documents can be uploaded to the public cloud and those requiring greater security uploaded to the private cloud. Costs will be charged per usage, based on the computing capacity used.

How does the Internet cloud work?

To access any type of server, you need to identify yourself with a username and password. Since all data is stored on a server, you only need to access it through an internet connection, allowing you to access it from anywhere and with any device.

As for computer applications, the work software is stored in the cloud, and the provider used is responsible for the constant updates that must be performed.

Depending on the services you need, you'll need a hybrid service, whether private or public. Fortunately, there are now a wide variety of companies that provide excellent cloud computing services.

In technical terms, the functioning of the cloud is divided into two parts:

• Front-end: represents the client’s computer or other smart device and the applications it needs to make use of the cloud.

Within the Front-End architecture we can identify 3 parts:

• The Software, which is the program that interacts with the cloud-hosted application from the user's side
• The User Interface, with which the client interacts to execute the task in the cloud.
• The Client or Device includes the hardware, the user's PC or notebook.

• Back-end: represents the servers, companies, and systems that provide the service. Back-end maintenance is the responsibility of the cloud service provider.

Also in the Back-End we can identify some basic components related to administration and security:

• The Application is the interface offered to the end user, but on the server side
• El Software It is the heart of the architecture and one of the main components of the system.
• Cloud Runtime is a type of operating system that allows multiple processes to run on the same server.
• Storage is where all the data needed to operate the software resides.

What is the “cloud” for?

You probably don't realize it, but every day you use applications or create documents that are stored in the cloud and don't use your phone or computer's storage. This is the case with Netflix and Google Drive, for example. In this regard, more and more companies have focused on leveraging cloud technology for their own services.

All of this stems from the idea of being able to access all your data instantly and at any time, wherever you are, and through any device—be it a mobile phone, smartphone, tablet, computer, etc.

Advantages and disadvantages of this technology

Advantages: cloud storage

Cost savings

Cloud storage saves costs because it eliminates the need for hardware to access terabytes of memory. This avoids the associated operating costs in the form of energy, air conditioning and administration expenses and at a much more affordable price, as they can also be affordable for small businesses.

Accessibility

You'll be able to access your data anywhere. You won't be dependent on a physical medium; you'll only need an internet connection. This is an opportunity to work remotely because you have all your files available anywhere.

Data recovery

With conventional storage, it's easy to lose data, but with the cloud, you'll have the opportunity to recover it by replacing physical drives. Thanks to cloud storage, you can maintain backups, which is quite beneficial for any user and/or business.

Security and more security

Today's cloud storage service providers add multiple layers of security to protect files or data from potential cyberattacks. They can also protect files from natural disasters, server failures, or user errors while preserving them.

You save storage on work equipment

All data is stored in the cloud. This way, your computer won't be so cluttered with files, which will boost your productivity.

Disadvantages: Cloud Storage

Internet connection

To access your documents, you must have unlimited internet access. It must be stable and powerful. Otherwise, you won't be able to access your files.

Additional costs

Because this is a system that requires a lot of maintenance, providers of this service may add costs depending on the volume of uploads or downloads from the cloud.

Vulnerability to cyberattacks

Some companies, especially large ones, may experience problems with cyberattacks. Therefore, they must better secure their cloud storage to prevent vulnerabilities.

Privacy policy

Your files become the responsibility of a third party. Therefore, you should ensure that the company managing your data is reputable.
