Types of cloud computing
Cloud computing refers to the delivery of computing resources over a network, offering various levels of management delegation and accessibility options. The cloud presents compelling advantages for managing internal infrastructure within organizations, leading to the emergence of three main types of cloud computing: private, public, and hybrid. In this article, we will explain the details and benefits of each type.
1. Private Cloud
A private cloud operates exclusively for a single organization.
This model deploys the cloud on the organization’s own infrastructure to deliver IT services to internal users.
Computing resources can be hosted within the company or in a dedicated data center.
With this model, the data center becomes more agile and flexible, leading to more efficient resource management. However, the cloud’s elasticity is compromised as scalability is constrained by the physical resources available within the organization.
2. Public Cloud
A public cloud is a model offered by external providers via the internet, available to anyone who wishes to subscribe.
In a public cloud environment, providers deploy services on their own infrastructure. These services may be offered for free or sold on a pay-as-you-go basis.
Due to resource sharing and the delegation of control to the provider, the primary challenges of this model include information security and service quality.
3. Hybrid Cloud
A hybrid cloud model combines public cloud services with private cloud resources, providing interoperability between both platforms and leveraging the advantages of each.
This interoperability is made possible because the private cloud can use interfaces compatible with those of public clouds.
Most businesses operate within a hybrid cloud environment, which enables scalability of both on-premises and local infrastructure.
Cloud Computing Services
Cloud computing services are classified into three main categories:
- IaaS – Infrastructure as a Service
- PaaS – Platform as a Service
- SaaS – Software as a Service
At its core, cloud computing is a tool that allows you to manage your data by reducing the burden of centralized data administration and making information more accessible to developers. In today’s fast-paced environment, maintaining a closed system complicates operations and delays the changes developers need to implement solutions for businesses and users.

In summary, cloud computing types are the result of evolving technologies that enable providers to configure a flexible infrastructure for each client (organization), offering access via a communication network in the form of self-service and pay-as-you-go services.
