cloud technology has become an indispensable ally.
This is because, with it, data and applications are stored on a global network of remote servers , allowing you to access information, documents and applications from anywhere, at any time, on different devices. This optimizes processes and increases competitiveness.
But when it comes to cloud computing, there are different types, and the public cloud stands out. This model is widely used by both companies and individuals, offering a shared infrastructure that results in a more accessible and economical service.
The tendency is for its use to become even more popular. According to studies by Gartner , global end-user spending on public cloud services is expected to grow 20.4% in 2024, reaching US$675.4 billion, compared to US$561 billion recorded in 2023.
Therefore, throughout the text, we will delve deeper into the concept of public cloud and show why it is the right choice for your business.
Good reading!
What is public cloud?
Public cloud is a cloud computing model where IT services, such as servers , applications, storage and databases, are offered by third-party providers. These resources are accessible via the Internet and intended to be used by individuals and companies on a shared basis.
In public cloud infrastructure, maintenance and management are the responsibility of the cloud provider , allowing users to focus on their operations without worrying about IT maintenance.
Additionally, the public cloud generally offers a lot of scalability and flexibility as its resources can be adjusted according to demand.
And when we talk about public cloud, three categories of services stand out:
- SaaS ( Software as a Service) : Applications accessible via the web.
- PaaS (Platform as a Service) : Service for developing and implementing applications.
- IaaS (Infrastructure as a Service) : Virtualized infrastructure such as servers and storage.
Each of these types of services has its own particularities and functionalities, and if you want to know more details about them, read: “IaaS, PaaS and SaaS: what they are and how to use them” .
What are the advantages of the public cloud?
The public cloud offers several advantages. Below, we detail the main ones:
- The first advantage is cost savings . But how does this happen in practice? Companies can reduce IT operational costs as they do not need to worry about purchasing and maintaining software and physical servers.
- Another point that can also result in savings is the scalability inherent to the cloud . The public cloud allows companies to increase or decrease their resources according to demand. Thus, the contractor only pays for the resources/services that it will actually use.
- Another important advantage of the public cloud is the greater availability and flexibility it provides. Data and applications can be accessed from anywhere with an internet connection, providing greater ease for the organization and employees.
- Furthermore, innovation is more easily achieved with the help of public cloud. This is because providers frequently update their infrastructure and offer new services and features, allowing companies to stay up to date with the latest technologies without additional investments.
- Lastly, security is an important consideration. While there are security concerns in the public cloud, many providers invest heavily in other advanced measures to protect user data.
Other types of cloud
This text is focused on public cloud, but it is important to also talk about other types of cloud that exist on the market. Did you know that in addition to public, there are two more types? The private and the hybrid.
Below, we will understand a little more about each one:
What is Private Cloud?
Unlike the public cloud, the private cloud is a computing infrastructure dedicated exclusively to a single organization .
This means resources are not shared with other companies, providing greater control and customization .
The private cloud can be hosted internally within the company or in a third-party data center, making it ideal for businesses with strict security and compliance requirements, as its resources, such as storage and networks, are provisioned on demand.
What are hybrid clouds?
As the name suggests, hybrid cloud combines public and private cloud infrastructures. In this model, some data and applications are kept in a private cloud, while other workloads run in the public cloud.
This approach offers flexibility to meet different business needs, allowing companies to choose where to allocate resources based on data criticality and sensitivity.
Furthermore, hybrid clouds allow efficient sharing of data and applications, enabling optimized resource management.
Differences between public and private cloud
As we can see, there are fundamental differences between the public and private cloud.
Public cloud:
In the public cloud, IT resources are shared among multiple users. These services are managed by external providers who provide infrastructure and support. Furthermore, there is great scalability of resources, generating cost savings.
Private Cloud:
A private cloud is exclusive to a single organization. Here resources are controlled internally or by a contracted third party, ensuring greater security and control. On the other hand, it is more expensive, due to the potential for customization.
| Feature | Public Cloud | Private Cloud |
| Accessibility | Shared among multiple users | Exclusive to a single organization |
| Control | Managed by third-party providers | Controlled internally or by contracted third parties |
| Scalability | Highly scalable | Limited scalability depending on infrastructure |
| Security | Good, but potentially less safe | Highly secure |
| costs | Minor | Bigger |
Both options have their advantages and disadvantages and the choice between these models depends on the specific needs of each company.
Why move to the public cloud?
The choice between public or private cloud is always complex, after all, there are several points that must be considered before choosing the model that best fits your business.
Migrating to the public cloud may be the right decision for companies looking to grow and adapt quickly to market demands.
Below, we list the main reasons that make this solution so attractive:
Greater scalability
The public cloud allows companies to scale up or down their IT resources as needed. It is possible to double or triple the amount of storage and computing resources in an instant.
This is especially useful for seasonal or rapidly growing businesses , as this scalability ensures that systems can handle variations in demand smoothly.
All this without the need for large investments in infrastructure.
Greater availability and flexibility
As we said, the public cloud offers high availability and flexibility .
Therefore, when migrating to this environment, all you need is a device with an internet connection to access information, documents, applications and much more. This is essential for remote work and improving team collaboration.
Additionally, the ability to quickly implement changes makes for a much more agile business environment.
Best value for money
The cost- benefit of the public cloud is another attraction. This is because companies only pay for the resources they use, avoiding expenses with maintenance and hardware updates.
Therefore, migrating to the public cloud can mean IT operational costs
Additionally, IT management is outsourced to the cloud provider, freeing up internal staff to focus on business initiatives
High performance
Public cloud providers continually invest in cutting-edge technology, ensuring that companies have access to up-to-date resources and can operate at high performance. This translates into better systems performance and greater operational efficiency.
More productivity
Public cloud resources accelerate project development and implementation thanks to their flexibility and advanced tools. This means that teams can launch new products and services more quickly, as well as work together on the same document or project.
data security
Although public cloud security is a common concern, providers invest heavily in protective measures. This includes data encryption, firewalls, and regular audits.
For many companies, the security offered by the public cloud may be superior to that available in internal infrastructures, especially if they are smaller companies with fewer financial resources.
Additionally, compliance with standards and regulations is often guaranteed, which is crucial for regulated industries.
Cloud expert team
Another interesting point is that public cloud providers have dedicated experts, guaranteeing high-quality technical support 24/7. This makes problem resolution faster and more effective.
