According to the NIST (National Institute for Standards and Technology), Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing refers to the practice of utilizing a network of remote servers hosted on the Internet to store, manage, and process data, as opposed to the traditional way which involved using a local server or a personal computer for the same purpose. In other words, cloud computing means storing and accessing data and programs via the Internet instead of…show more content…
In SaaS, applications are hosted by a vendor or service provider and made available via a network to clients, in most cases through the Internet. Platform as a Service (PaaS) is often used for providing operating systems and associated services via Internet which doesn’t require any downloads or installation by the client. Infrastructure as a Service refers to outsourcing the equipment that is used to support operations, such as hardware, servers and other networking pieces. There are four deployment models of cloud computing. Each one has its unique benefits, therefore, the most suitable to a business must be chosen wisely. In the public cloud model, the cloud computing infrastructure is hosted at the vendor’s premises by the cloud vendor. The customer doesn’t know about the structure of the cloud nor has control over the location where computing infrastructure is hosted. In the public cloud, the computing infrastructure is shared among organizations. In Private cloud, the computing infrastructure is for one single organization and not shared with any other entities. Some say that private clouds are not considered a part of cloud computing. In comparison to public clouds, private clouds tend to be more expensive but more secure. There are two types of private clouds: On-premise private clouds and externally hosted private clouds. Externally hosted private clouds are hosted by a third party that specializes in cloud computing
