Introduction
With the advancement of digital transformation, cloud computing has gone from being a trend to becoming the foundation of operations for companies of all sizes. Gartner projects that global cloud investments will exceed US$723 billion by 2025 , a leap driven by the need to scale services with greater agility, flexibility, and security.
Within this scenario, AWS ( Amazon Web Services ) stands out as one of the most widely used platforms in the world . But with such a broad portfolio of services, it's natural that many companies feel lost when trying to understand which solution really makes sense—and, especially, how much it will cost.
To avoid this scenario , having a tool that translates the complexity of AWS into financial clarity is a strategic step. That's why we created the Skyone cloud calculator , a resource that allows you to visualize, simulate, and plan your cloud investments with much more security.
In this article, we will show you how it works, why it makes a difference in your decision-making process, and how to use it to transform the cloud into a real ally for your business.

What is AWS and why do so many companies use it?
When discussing cloud computing, it's impossible to ignore the acronym that has become a global benchmark: AWS. But what exactly is behind these three letters, and why do they appear in so many conversations about technology, innovation, and scalability?
Amazon Web Services is Amazon's cloud platform , created to offer solutions ranging from data storage and processing to advanced artificial intelligence, machine learning , security, databases, and more. AWS's great differentiator lies in its scope : hundreds of services are available on demand, ready to serve everyone from startups to large corporations.
It is precisely this variety that makes AWS such a popular choice, and at the same time, so challenging. In practice, many companies come to the platform aiming to innovate or reduce costs, but are faced with such a vast portfolio that they don't know where to begin . And it is at this point that questions arise such as: "Which service do I really need?", "How much will this cost?", or "How can I predict the impact on my budget?".
Therefore, understanding what AWS is and what it offers is the first step towards making more informed decisions about its use, and especially about how to calculate these investments more safely.
Next, we'll delve into the basic concepts of cloud computing so you can understand the complete picture before choosing the best solution for your company.
Understanding cloud computing
When we talk about cloud computing, it's common to think only of "storing data on the internet." But that's just the beginning.
In reality, the cloud represents a profound transformation in how companies access, use, and pay for technology —completely changing the logic of traditional infrastructure.
For those taking their first steps on this journey, understanding the fundamentals is essential. Therefore, we've gathered the main concepts here so you can clearly understand what the cloud really means and why it has become a strategic choice for organizations worldwide.
What is cloud computing?
Cloud computing is a model that allows you to use technology resources (such as servers, databases, software , and storage) via the internet , without needing to physically install anything in your company.
In practice, this means that your IT infrastructure is no longer limited to a physical space and is delivered as a service . In other words, you access what you need, when you need it, paying proportionally to your usage.
In an analogy, it's like trading the purchase of a generator for an electricity bill : you no longer need to worry about maintenance or idle capacity, but only about the results it delivers to your business.
Why migrate? Real advantages for companies
Migrating to the cloud is more than just technological modernization: it's a strategy for efficiency, speed, and resilience . Companies that adopt the cloud can scale operations quickly, test new solutions with less risk, and significantly reduce operational costs.
Key benefits include elasticity (adjusting resources according to demand), agility (accelerating launches and adaptations), and security (with updated standards and constant monitoring).
For businesses that need to respond quickly to market changes, the cloud offers the ideal foundation for growth without compromising structure or budget .
On-premise infrastructure vs. cloud: what changes?
In an on-premise infrastructure, the company buys servers, builds data centers , and is responsible for all operation, maintenance, and system updates. This requires high investments and rigid capacity planning , which often results in waste or bottlenecks.
In the cloud, this model changes completely. Instead of buying, you "rent" resources on demand , with automatic scalability and payment proportional to usage. This gives more freedom to innovate and ensures that the company only pays for what it actually consumes. Furthermore, it's a way to transfer operational complexity to specialized providers, such as AWS itself.
Main cloud service models
To facilitate adoption and meet different levels of need, the cloud is organized into three main models :
- IaaS ( Infrastructure as a Service ) : This is the closest thing to traditional infrastructure. You contract servers, networks, virtual machines, and disk space, with complete freedom to configure them. Ideal for companies that want technical control without the burden of purchasing and maintaining physical resources.
- PaaS ( Platform as a Service ) : provides a ready-to-use environment for developing, testing, and running applications. The focus here is on accelerating development without worrying about infrastructure—the provider takes care of the foundation, and your team focuses on innovation.
- SaaS ( Software as a Service ) : These are software programs accessed directly via the internet , such as CRMs, ERPs, collaboration tools, or email . You don't need to install anything: just access and use.
Each model caters to different realities, and, as we will see below, directly influences the costs and how your company will consume the cloud.
How are cloud costs calculated?
While the cloud offers scalability and agility, it also demands extra attention to how costs are managed . This is because the traditional model, based on licenses or one-off purchases, gives way to a completely different logic: pay-per-use. Understanding how this dynamic works is fundamental to avoiding budget surprises .
At this point, we encounter one of the biggest pain points faced by companies that adopt AWS without proper planning: the difficulty of accurately predicting costs. But before we talk about how Skyone solves this challenge, it's important to understand how this logic is structured .
Pay-per-use concept
In the cloud, you don't pay for a fixed package or annual license. Instead, the model is similar to a utility bill: you are charged based on the amount of resources used , whether it's processing, storage, data transfer, and/or service execution time.
This model is advantageous because it allows small businesses to access robust technologies without large initial investments . But, at the same time, it requires active and conscious management of usage. After all, the more you consume, the higher the bill will be—and it's not always easy to visualize these numbers at the beginning of the journey.
Main factors affecting cost
Although the logic is simple, the details that make up the billing can be complex. Cloud costs vary according to different factors , and knowing these elements is essential for accurate estimation.
- Type of service contracted : computing instances, storage, databases, artificial intelligence (AI), among others. Each service has its own pricing model;
- Geographic region : AWS has data centers spread around the world, and prices vary depending on the chosen location;
- Data traffic : moving data between zones, services, or out of the cloud can generate additional costs (often invisible at first glance);
- Usage time : you pay for the time that resources are active. This requires attention to turning off idle or underutilized services;
- Instance type and performance : More powerful instances (with more CPU, memory, or GPU) naturally cost more. The challenge is finding the ideal balance between performance and budget.
With so many factors at play, the final cost can vary considerably. And this is where the strategic role of tools like Skyone's cloud calculator , helping to simulate different scenarios and predict impacts with clarity .
