Finally discover what cloud computing is and what cloud computing is for – WAU

Cloud computing, also known as cloud computing, is the technology that allows remote use of computing resources through Internet connectivity. Do you want to know more about her? Then read our post!

Few terms have been as popular in the technology world as cloud computing. Nowadays, it seems that everything happens in the “cloud”.

Who does not know what it is, seeks to know more about the subject, who knows, seeks ways to implement it and who already uses it, always talks about the excellent results he gets from it.

If you are in the first group and the concept of cloud computing turns your head, in this article you will discover everything you need to know about cloud computing, the Internet cloud. Keep reading!

What is cloud computing?

Cloud computing is a technology that uses connectivity and the large scale of the Internet to host the most varied resources, programs and information. Thus, cloud computing allows the user to access them through any computer, tablet or cell phone.

All without the need to connect to a personal computer or local server.

If it’s not clear yet, let me give you an example: if you’ve edited a document on Google Docs, listened to music on Spotify, or watched a movie on Netflix, you’ve had direct contact with cloud computing.

All of them are online services that do not require the download, installation and access of any type of software or file on your computer. You just need a browser and a good internet connection to use them.

What is cloud computing for?

If we analyze the traditional model of computing, in which users and companies need to invest in downloads, hardware, operating systems and software to get some kind of application, it is easy to understand why cloud computing has become so popular.

The cloud emerged as a way to democratize information and improve the experience of those who depend on technological resources on a personal or professional level.

Cloud computing has brought numerous advantages. The option for a cloud service allows:

Reducing infrastructure costs: as it eliminates capital expenditures for hardware and software purchases, installation and maintenance;

The economics of space: given that the resources remain stored online;

Centralizing information: preventing all data from being kept in different programs, with different types of forms of authentication and access;

Increase or decrease according to the customer’s need: thanks to the elasticity power that provides the ideal amount of resources, storage and processing;

Remote work: Company employees can access all data through any computer, notebook, tablet or smartphone, as long as they are connected to the Internet.

In addition, we can mention the quality of security, the automatic update of the server, the usability of the platforms, the technical assistance services and backups.

Amid so many benefits, cloud computing has become the preferred choice of many companies and users in general. Not in vain, practically everything we currently consume on the Internet – social networks, file storage, streaming video and music – comes from applications and services hosted in the cloud.

How does cloud computing work?

Cloud computing uses a remote server to connect users’ devices to centralized resources. A remote server stores all the data and programs you need and can be in your own country or on the other side of the world, for example, in Japan.

The fact is that you can access them online, from anywhere, even if they are stored miles away.

There are 3 types of cloud computing: the public, the private and the hybrid. If you have a business and plan to use a cloud service, keep in mind that the choice will depend on factors related to cost, availability, performance and expectations. Next, you’ll see how each cloud works:

Public Cloud

They are computational resources, such as servers and storage, provided by third parties and available to any person or company that wishes to hire them.

In this model, the customer is responsible for what will be sent to the cloud, be it a backup, an application or some files, while the cloud provider is concerned with the maintenance, security and management of all resources.

In the public cloud, everything is available on the web and shared between multiple users who use it simultaneously (but separately), which keeps features standardized.

By offering unified solutions, this model ends up being cheaper. Therefore, the public cloud is suitable for companies that want to save on investments.

Private Cloud

In this model, the company maintains the cloud infrastructure in its internal domain and offers restricted access to selected users, such as employees and partners.

The private cloud offers the company the possibility to customize the functions and support its needs. As the cloud is designed exclusively for it, all processes are directed to the business reality.

In general, the private cloud is used by organizations that must follow certain regulations and rules specific to the security and privacy of data and information, as is the case with some financial and government institutions.

Hybrid cloud

Finally, when we talk about the hybrid cloud, we refer to the union of the previous two, that is, the combination that allows sharing data and applications between the two types of cloud mentioned.

Thus, according to the business need and strategy, some resources are used privately, others are used publicly or are connected through technologies.

What services does cloud computing have?

Currently, cloud computing offers a wide variety of services, tools and functionality to meet the needs of companies. Among the main offers, there are 3 models:

SaaS (Software as a Service)

SaaS allows you to access the software without purchasing your license, using it for free in the cloud, usually with limited resources.

However, there are also payment plans in which a fixed fee is charged, an amount that varies according to use or even free of charge, whether the resource offers advertisements or other form of monetization.

In this format, the company accesses the software over the Internet, without having to worry about installing, configuring and investing in licenses.

Many CRMs and ERPs work through SaaS. E-mail services and other public applications such as Skype, Whatsapp, LinkedIn and Facebook also work with this type of model, which is why it is the most popular mechanism.

PaaS (Platform as a Service)

In this cloud model, a complete development environment is contracted on demand, in which it is possible to create, modify and optimize software and applications.

The advantage of the PaaS model is that it includes operating systems, development tools, database management systems, Business Intelligence services and many other features, in addition to all the infrastructure needed to run or improve web or mobile applications.

The development team only has to worry about programming the application, since the administration, maintenance and updating of the infrastructure are left to the provider.

IaaS (Infrastructure as a Service)

In the IaaS model, infrastructure resources are rented, such as servers, routers, racks, datacenters, hardware and other tools that allow the transmission and storage of data.

Depending on the provider and the model chosen, the company may be charged, for example, for the number of servers used and the amount of data stored or trafficked.

In the IaaS model, what is needed is used according to the company’s demand and only what is used is paid.

The great advantage of this model is its scalability. After all, in one month, you may require some virtual servers where you will store little data and have little traffic, while in the next month you will be able to request twice as many resources.

Thus, the mechanism works like hiring a cable TV service, it is possible to cancel it, increase it or reduce it at any time.

Conclusion

Now that you understand the concept of cloud computing, I recommend that before thinking about the best model for your business, reflect on your business needs and prioritiesbecause it is based on them that you will decide which services are essential and that need this type of investment.

Setting the available budget will also help you choose the best implementation system: SaaS, PaaS or IaaS.

Analyze the features and functionality you need and look for the providers that offer them, for example, encryption and other security methodologies, efficient backup services, 24-hour technical assistance, etc.

Anyway, it is always good to see the cloud, at first, as an environment for experimentation and testing.

There is a wide variety available on the market, analyze and perform tests, observe how your company behaves when using this type of service and implement, little by little, the cloud computing in their processes.
