Cloud computing is one of the solutions most adopted by companies today to improve their performance through digital transformation.
Cloud computing, also known as cloud computing, is a well-known term in the technology environment. It is not today that the “cloud” has become a partner, very famous for the results and benefits it provides for those who have already surrendered to its help.
As this is a global trend that the market cannot ignore, we brought this text to clarify the information you need to understand everything about cloud computing.
If you want to delve into this subject in detail, keep reading!
What Is Cloud Computing?
What is this “cloud”, anyway?
Speaking more technically about cloud computing, we can define it as a technology that uses internet connectivity and its broad reach to store different resources, programs and data.
This tool allows remote access to these files; from any computer or mobile device, it is possible to access them without necessarily having a personal server.
Nowadays, several services share this idea, such as Google Docs, Drive, Spotify, and Netflix, among others.
Any service that allows you and others to access the same file from different parts of the world over the internet uses this technology.
You must have already understood how revolutionary cloud computing technology is from these brief examples, right?
How Cloud Computing Works
Cloud computing uses a remote server to connect users’ devices to a resource center.
This remote server in question is responsible for storing all the data, information and programs you need. It can be close to you or at great distances, such as in another country or continent.
What matters is that you can access them once you’re online.
To explain in more detail how this technology works, you must understand that there are three types of cloud computing and the diversity of services offered by this functionality.
Types Of Cloud Computing
As we said, there are three types of cloud computing. They are classified as: public, private and hybrid.
The important thing in the variation of these types is that, for the entrepreneur who intends to use this service, it is essential to understand that the choice depends on several factors, such as cost, availability, and performance.
But so you already know more about them, let’s explain how each one works:
Public
The public cloud is based on computing resources provided by third parties that serve different customers; they are available to anyone who wants to hire them.
When adopting this model, the customer must know that he is responsible for the data that is sent to the cloud, as the provider itself will only take care of ensuring maintenance, security and resource management.
Private
In this other cloud computing model option, the company maintains the entire cloud infrastructure in its domain, that is, internally. From there, it can offer restricted access to selected users, such as collaborators and partners.
The private cloud gives the company functional autonomy to customize functions and support according to its needs.
Considering that in this cloud computing system, everything is designed exclusively for the company, everything is targeted in a specific and personalized way.
Although it has higher costs, in general, the private cloud is preferred when the context is to store more strategic data that needs a fast response time.
That’s because as the servers are inside the company, they guarantee a low proportion of network errors and greater security since no one outside the company will have access to that data.
For this reason, it is pretty standard in governmental and financial institutions.
Hybrid
The hybrid model of cloud computing is nothing more than the union of the two previous ones, which allows the sharing of data and applications publicly and privately and has software that allows this transfer of workloads between both.
In this way, the company can use its resources according to the need and strategies of the moment.
This is considered the ideal model because the company has a lot of local computing resources to handle routine tasks. Still, when it needs to practice the more complex tasks, it will also have a sound cloud model at its disposal, being able to allocate complementary resources from an external supplier.
Cloud Computing Services
Cloud computing offers a variety of services and features aimed at meeting the demands of companies.
Below we will better contextualize three of them, highlighted among the main ones.
Software As A Service (SaaS)
SaaS, or software as a service, is nothing more than a type of application created for a specific purpose, in which it will act as a service.
It can be used for free in the cloud, requiring a monthly payment for the service, unlike usage licenses, where only one payment is required to make the acquisition.
In this model, Google Docs, Drive, Dropbox or ERP software, which can be paid, fit.
Platform As A Service (PaaS)
PaaS, or platform as a service, is when the supplier delivers a software development platform, which can be applied in different environments or even in a single supplier.
It works on demand, making it possible to create, improve and optimize software and applications as needed.
Infrastructure As A Service (IaaS)
In IaaS, or infrastructure as a service, the infrastructure resources, such as servers, data centers, and hardware, are rented. All features linked to data transmission and storage can be used for a monthly fee.
