1. Private cloud
The private cloud is useful for industries that have few branches and do not want to depend so much on data communications over the internet, when performed in the company's own physical installation (the vast majority of cases). It is also used when the contractor wants to maintain his investment in assets (equipment) but seeks a more physically secure environment than his own facilities, allocating his equipment within private spaces in professional data centers. In general, this type of cloud is indicated for companies willing to invest in IT equipment and centralize the infrastructure in the headquarters or in professional data centers.

The private cloud obliges the client to hire a team (internal or outsourced) of specialists in IT infrastructure, with varied skills (virtualization, database, operating systems, maintenance and configuration of equipment and networks) and does not allow cost sharing of this team and equipment among several customers. It is usually limited to very large companies that have a centralized strategy for their IT. It can also be recommended in case of a great shortage of quality internet. It is important to note that private clouds have very high costs.

2. Public cloud
Unlike the private, the public cloud is for companies that want to avoid a centralized IT architecture. Today, in many cases, the architecture is still hybrid, in a progressive process of migrating applications from the on-premises environment to the public cloud.

The public cloud offers a very high level of security (physical and logical) and availability for the IT environment without having to invest in equipment and licenses, transferring IT expenses from CAPEX (Capital Expenditure, or capital expenses, are the costs acquisition of equipment and facilities) for OPEX (Operational Expenditure, or operating expenses, as it is an infrastructure contracted as a service, which allows constant adjustments), providing operational and financial flexibility.
