The concept of cloud computing started in large-scale Internet service providers, such as Google (Google Cloud Services), Amazon AWS, Microsoft Azureor Alibaba Cloud and others who built their own infrastructure. So, what are the type of cloud hosting servers?

1- Public Cloud Server

When we talk about public cloud, we mean that the whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service.

2- Private Cloud Server

Uses dedicated, private hardware. Private cloud means using a cloud infrastructure (network) solely by one customer.

3- Hybrid Cloud Server

Hybrid cloud, of course, means, using both private and public clouds, depending on their purpose.


In this type of computing all that a computer system can offer is offered as a service, so that users can access the services available “in the Internet cloud” without knowledge in the management of the resources they use. According to the IEEE Computer Society , it is a paradigm in which information is stored permanently in Internet servers and sent to.

So, cloud computing are servers from the Internet that are responsible for responding to requests at any time. You can access your information or service, through an internet connection from any mobile device or landline located anywhere. They serve their users from several hosting providers frequently distributed around the world. This measure reduces costs, ensures a better uptime and that websites are invulnerable to computer criminals , local governments and their police raids.

Cloud computing is a new model for the provision of business services and technology, which allows the user to access a catalog of standardized services and respond with them to the needs of their business, in a flexible and adaptive manner, in case of unforeseeable demands or peaks of work, paying only for the consumption made, or even free of charge in the case of suppliers that are financed by advertising or non-profit organizations.

The change offered by computing from the cloud is that it allows increasing the number of services based on the network. This generates benefits both for suppliers, who can offer, more quickly and efficiently, a greater number of services, as well as for users who have the possibility of accessing them, enjoying the ‘transparency’ and immediacy of the system and a model of payment for consumption. Likewise, the consumer saves the salary costs or the costs in economic investment (premises, specialized material, etc.).

Cloud Computing manages to provide these advantages, relying on a dynamic technological infrastructure that is characterized, among other factors, by a high degree of automation, a rapid mobilization of resources, a high capacity to adapt to meet a variable demand, as well as advanced virtualization and a flexible price depending on the consumption made, avoiding also the fraudulent use of software and piracy.

The concept of “cloud computing” is very broad, and covers almost all possible types of online service, but when companies preach offering a utility hosted in the cloud, they usually refer to any of these three modalities: software as a service (for its acronym in English SaaS -Software as a Service-), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

Software as a service (SaaS) is a software distribution model in which applications are hosted by a company or service provider and made available to users through a network, usually the Internet. Platform as a service (PaaS) is a set of utilities to supply the user with operating systems and associated services through the Internet without the need for downloads or any installation. Infrastructure as a Service (IaaS) refers to the outsourcing of equipment used to support operations, including storage, hardware, servers and network components.
