The term âCloud Computingâ as it is understood now is relatively recent: It was in years 60 when the possibilityÂ imagined for the first time of distributing to the computers as resources public. The concept was to have the distributed capacity of calculation of the same form that operates public the Mains: that is to say, infrastructure that is consumed âunder demandâ and is pleased by use, with a series of suppliers that are in charge of all the details. Nevertheless, the idea has remained latent until the beginning of the 21st century.
Recently, the advances in availability of connection to Internet of high speed have allowed the commercialization of before unthinkable services, as âSoftware ace to Serviceâ (SaaS, software as service). Since then, giants of computer science such as SalesForce.com, Google, IBM, Apple or Microsoft have even made advance this field enormouslyâ¦ and it seems that only the surface has been scratched than it is possible.
To day of today, there are five âmain cloudâ types available:
|A service of âPublic Cloudâ is that one to which it is acceded by means of Internet (that is a public network): the use of the resources follows the model of consumption under demand. Although the name could suggest the opposite, each user has own, separated data of the rest, and that can be shared.|
|A service of âPrivate Cloudâ is that one that is designed for companies and that can work within the own company. Unlike the services public, he is available only for the personnel of the company, and usually it is not operated by an external supplier.|
|The hybrid model of âcloudâ combines as much resources public as private, based on the different needs from the company: for example, the department of human resources/lists could use a deprived service, whereas other functional areas of the company use services on public infrastructure (mail, backup offsite, etc)|
|This variety, unlike the others, does not imply virtualization: the applications run on ânaked metalâ (it beaches metal), to take advantage of to the maximum the yield the equipment hardware which it is had.|
|This service, our favourite, has the particularitity of which the supplier â specialized in these tasks it is in charge to operate and to maintain all the infrastructure in perfect state so that the company can be concentrated in its business and offering value to its clients.|
Each type on watch âcloudâ has his own benefits and disadvantages, although of course there are great global benefits in the use of any type of Cloud Computing: the services cloud allow him, for example, to accede to all their information in any place that has connection to Internet â this could suppose the aim of pendrives USB and other portable storage devices every time our information is available from any point of the globe.
Still more, this constitutes a great jump of possibilities for those businesses that need to share information with average worldâ¦ but the possibilities are not only limited files: it is possible to be also acceded to all the programs and configurations that we need in the same way. A potential benefit is in the availability of the information: the loss or subtraction of a laptop does not imply the loss of great amount of valuable information, but only a misfortune; The great datacenters have the infrastructure and the personnel necessary to maintain the data to good collection moreâ¦ than the average company it can be allowed, and far better that in its own house.
