Of course, each business has its particularities and specific needs, so it is necessary to analyze some points before choosing the cloud. Throughout this article, the details of each of the clouds available in the current market will be punctuated.

Why is cloud software different from traditional software?

What is public cloud? 

Public clouds are an information technology service in which the physical structure (server, air conditioning, etc.) and people (technicians) are outsourced , that is, they are not within the domain of the company that hired them.

Providers of this type of cloud also offer cloud-based services to their customers, such as IaaS, PaaS, and SaaS, and charge a monthly or annual fee for using this offsite data center. 

By opting for this cloud model, the company saves capital by not having to expand its physical structure , which would happen, for example, in the case of creating/increasing a private cloud.

Another advantage comes at times of peaks, unpredictable or not, as it is possible to buy a virtual desktop just for that specific period. This avoids possible crashes on websites and applications due to the large number of accesses in a single moment.

In summary, the main advantages of using a public cloud are:

  • Economy in the purchase of equipment and software;
  • Reduction in maintenance cost; 
  • Less need for human resources;
  • Availability of desktops on demand;
  • Predictability of expenses, among others.

Being in a shared environment, data security is a point of concern for companies that hire a public cloud. 

However, the reality is that by having the biggest players in the cloud computing market, such as Oracle, Google Cloud and AWS , your business now has the best cybersecurity practices.

Also pay attention to the data laws in force where your company is located, as many countries require that some types of data from their organizations be stored in their territory. In these cases it will be necessary to opt for a national solution.  

What is Private Cloud? 

In the private cloud, a company's computing resources are located within its own structure , that is, the data center and the responsible technicians are private resources . Both services and equipment belong to the company.

As an advantage, hardware and software are exclusive to a single organization, in addition there is less concern with security when using a private cloud since there is more control over the environment.

However, the cost of maintaining a climate-controlled data center with technicians and seasonal maintenance is high. Companies that have private clouds also need a redundancy environment (reserve equipment) ready to operate in case of failure.

Therefore, a private cloud requires a much greater availability of capital for the IT area. In addition, when opting for this model, the company will need qualified people who can operate this equipment, professionals who are in great demand today.  

What about hybrid clouds?

Hybrid cloud, as the name suggests, is a blend of public and private cloud , so companies can take advantage of both models at the same time. However, this type of cloud has a high deployment cost.

In it, part of the data would be stored in local equipment and part in the provider's system. Even though it seems like the best solution to the security issue, the encryption between the two main cloud models is different and can generate errors.

What is the difference between public and private cloud?

The main technical difference between public and private cloud is where the company's data is stored, within the organization itself or at a public provider that offers this service to several companies.

And that implies financially, without having to invest in equipment, software, skilled labor, air conditioning, generators and in a redundancy environment, the company saves on several fronts by opting for the public cloud.
