Cloud Computing or Cloud Computing, is the technology that allows dynamic allocation or according to demand, of the computational capacity (processing, memory and storage) of large, robust systems, distributed spatially and in variable percentages to meet the different demands of any users who need storage, services and applications, remotely through the Internet .
Do you understand? Possibly not and it is understandable that not.
This possible definition may seem somewhat abstract or even a jumble of words to those totally lay on the subject. Even for those who are not an expert, or a reasonable connoisseur of digital technologies, it is not simple.
Then comes the question of what is SOW (statement of work) of any given project or assignment. Few of us get along that SOW is the same as the scope of work.
The first factor of complexity comes from breaking paradigms that until then were considered untouchable.
In computing, from the beginning, it was always possible to say where each thing was and the role of each component. You were able to answer where your data was recorded, what processing was available on your computer or terminal, where your programs were installed, among a series of possible questions. But what about today?
It may still be that the answer is easy and clear in some cases. But depending on how adept you are of the many services available on the Internet, no more.
If you have documents on Google Docs or Office 365 , miscellaneous files on i Cloud or Dropbox , photos on Flickr or Google Photos , listen to music from Deezer or Spotify , a website hosted on a server that uses Cloudlinux or simply install Apps on your smartphone , you are using the cloud or a cloud computing service.
In any of the above cases, who is able to tell where this content is physically available?
Naturally at a point in the server infrastructure of the company responsible for the service, but the place (space) in which it is located, perhaps not even the technical area of the same is capable of responding.
Let's use Office 365 as an example.
In the past, if you needed an office suite, you had to buy a license, install it on your PC or notebook and you could only use it on that computer. Everything - created documents and applications - was physically “confined” on that device. A pendrive, an SD card or an older CD or DVD were the options for saving documents to removable memory , if you needed them on a trip, for example.
