What’s New On Computing In The Cloud

What’s New On Computing In The Cloud.┬áStudents frequently ask: what is cloud computing? What are cloud services? What is the cloud site? What is cloud, cloud file storage? How to use in the teaching of cloud computing? Saas service for B2C and B2B sale? Solutions and SaaS ERP systems and CRM SaaS? What cloud computing models are used to develop Web applications? The modern datacenters that create services in the cloud: SaaS, IaaS and PaaS in?
First, consider that “the cloud” (cloud) and “cloud computing” (somputing cloud). The ‘cloud’ is an innovative model (concept) of the Organization of the IT infrastructure, which consists of configurable distributed and shared hardware and network resources, as well as software, deployed (cloud) remote data center providers (providers). The cloud is a new approach to the IT infrastructure organization.
Cloud computing is a model of remote access to shared resources that are physically distributed across many remote devices that make up the so-called cloud (cloud).
Cloud computing is a model to provide scalable consumer computing resources as a service over the Internet. The cloud is the view model to the consumer is as a service over the Internet.
Fundamental analysis of cloud computing definition, proposed by the National Institute of science and technology on July 24, 2011 year.
The definition of ‘cloud computing’
Cloud computing cloud model enabling ubiquitous and convenient demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be provided quickly and be saved with minimal effort to control or interaction with the provider of the service (provider). This model is presented in the clouds (above) the five main characteristics, three service models and four deployment models.
The main characteristics of cloud computing, which distinguish them from other types of (Internet resources) computing:
Self-service in demand. The consumer as needed automatically, without interacting with each independent service provider can determine and change the amount of data storage the power of calculation, as the server time,.
Wide network (generic). Computational power available over long distances across the network through standard mechanisms that promote a wider use of heterogeneous platforms (thin or thick) client (terminal devices).
The pooling of resources. Configurable computing resources of the supplier are merged into a single pool to share a large number of consumers of distributed resources.
Give instant (instant scalability) resources. Cloud-based services can be provided quickly, grow, shrink and exempted based on the needs of the consumer.
Measured service (consumption of services of registration and the possibility of payment for services that were actually used). Cloud systems automatically administration and optimizing the use of resources through the implementation of measures at some level of abstraction corresponding to the type of service.
If the model (concept) provides distributed and shared of configurable computing resources complies with the above features, then it is cloud computing.
Model of cloud computing or cloud computing service:
Software as a service (SaaS) – software as a service. In this model, providing for the used provider application is running in the cloud, the cloud computing that are available to the client through the interface (web browser), or the program’s interface. Consumers can manage and control the underlying cloud infrastructure including servers, operating systems, network and data stores or even change settings specific to the application.
Platform as a service (PaaS) – platform as a service. Cloud computing model of delivery in which the user obtains access to use software platform: management systems of databases, software implementation, systems, development tools and testing. In fact, the user gets a computer’s platform leased with the installed operating system and specialized tools to develop, deploy and manage Web applications. The consumer has no control of basic infrastructure, including network, servers, operating systems, or data warehouse cloud, but manages deployed applications and configuration settings is possible Wednesday environment
