Cloud Computing in Switzerland is a general term for anything that has to do with the provision of hosting services through the Internet. These services are divided into three broad categories: Infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). The name of cloud computing was inspired by the cloud symbol that is often used to represent the Internet in images and flow diagrams.
The services in the cloud have three well-differentiated features that differentiate them from modern hosting. On the one hand, charging is done according to usage, usually per minute or per hour; the service is elastic, since the user can use as much as he wants and at the moment he wants; finally, the service is achieved entirely by the earner (the consumer does not need anything except a personal computer and Internet access).
The important innovations in virtualization and distributed computing, the great advances in the speed of access to the Internet and the widespread economic weakness have given a great boost to cloud computing.
The clouds can be private or public. A public cloud is the one that sells Internet facilities to any user. (Currently, Amazon Web Services is the main earner in a public cloud). Private clouds are a network or data center that belongs to an organization and offers hosting services to a limited number of people. When the service provider uses community cloud resources to create its private cloud, the result is called a cheap virtual private cloud. Whether private or public, the goal of Cloud Computing in Switzerland is to provide access to computing resources and IT services in a simple and scalable way.
The infrastructure as a service - a good example is Amazon Web Services - offers a virtual server instance (API). In the original it is also "spaced" CHECK to start, stop, access and configure its Cheap virtual server and storage. In the business field, cloud computing allows companies to pay only for the capacity used and go to the network as necessary. Since this model based on pay-per-use is similar to the way to consume electricity, gasoline, and water, it is sometimes spoken of computing as a basic service (utility computing).
The platform as a service (PaaS) in the cloud is separate as a set of software tools and the development of goods hosted in the group of the service provider. PaaS providers can use APIs, Internet portals or Web Gateway software installed on the user's computer. Programmers should know that, currently, there are no standards for interoperability or movability of information in the cloud. Some providers do not allow their customers who have created software to move it from their podium.
In the software as a service (SaaS) model, the provider provides the hardware infrastructure, the software product and relates with the user through an access portal. The SaaS market is very broad. The services accessible range from web-based email to inventory control and database processing. Since both applications and information are hosted by the facility provider, the end-user is totally free to admission the service from any point.
