Different sourcing models can be evaluated against all three standards: cost, control, and scalability. Public cloud The public cloud is a set of computing services that are delivered over the Internet. It is offered by a provider, who generally uses a pay-as-you-go model. Public cloud computing has the following attractive attributes: you only pay for resources you consume; gain agility through rapid implementation; there is rapid capacity scaling; and all services are delivered with improved and consistent availability, resilience, security, and manageability. Public cloud options include: Shared Public Cloud - Shared public cloud provides the benefit of rapid deployment, massive scalability, and low cost of entry. Delivered in a shared environment where architecture, customization, and security grade are designed and managed by the vendor according to market-driven specifications Dedicated public cloud - The dedicated public cloud provides similar functionality to a shared public cloud, except that it is delivered on a dedicated infrastructure. Security, performance, and sometimes personalization are better in the dedicated public cloud than in the shared one. Its architecture and service levels are defined by the provider and the cost can be higher than that of the shared public cloud, depending on the volume Private cloud The private cloud is a set of computing resources that are delivered as a standardized set of services specified, designed and controlled by a specific company. The path to a private cloud is often driven by the need to maintain control of the delivery environment, application maturity, performance requirements, and business or regulatory differentiation reasons. For example, banks and governments have data security problems that can prevent the use of currently available public cloud services. Private cloud options include: Nube privada auto-hospedada: una nube privada auto-hospedada proporciona el beneficio de control arquitectónico y operativo, utiliza la inversión existente en personas y equipo, y proporciona un entorno local dedicado que se diseña, hospeda y administra internamente Nube privada hospedada por un socio: una nube privada hospedada por un socio es un entorno dedicado, diseñado internamente, pero hospedado y administrado externamente. Mezcla los beneficios de controlar el servicio y el diseño arquitectónico con los beneficios de la contratación de recursos externos Private Cloud Appliance - A private cloud appliance is a dedicated environment that, sourced from a vendor, is designed by that vendor with vendor- or market-driven features and architectural control; in addition, it is hosted internally and administered externally or internally. Mix the benefits of using predefined functional architecture, lower implementation risk with the benefits of internal security and control shortcuts
