Another important point when it comes to scalability is the choice of the type of cloud that will be adopted by the company. There are three: public, private and hybrid. Each business, according to its particularities, needs to evaluate which one best fits.

In this model, the entire computing infrastructure is located on a provider's premises. The resources are shared by several customers - each with their highly secure and isolated level of access to their own data.
The public cloud is recommended for companies that need high technological power and cannot or do not want to have high investments. It is necessary for IT professionals to understand with the provider what workloads could be migrated to the public cloud due to their specificities. Agility is an attribute of this model because it is a ready-made environment, with installed capacity ready to be sold.
The private cloud is an infrastructure used only by one organization to serve all of its business units. Companies also have the option of choosing a private cloud on-site, which is more expensive, and requires greater physical control and all the complexity of operational management to keep this structure under the company's direct control.
This is a recommended cloud model for businesses that have very sensitive data and internal standards that require complete control of the infrastructure. This is the case for banks, for example.
The hybrid model, as the term itself suggests, is a mixture of the two types of cloud mentioned above. In it, companies create internal clouds and, at the same time, also take advantage of public cloud resources.
