Cloud Around Us

Abstract

End-users share a wide variety of information on Facebook, without being aware of where the data is stored and
how security issues are concerned. The paper discusses how Facebook magically implements cloud in real world and which
cloud technologies are used to store the vast data user uploading on daily basis. Facebook was build on ground-up as a website
or a “cloud application” SAAS (Software as a Service). It’s success with users is that it just works- no matter what device you are
on, no matter what network connection you have, and no matter what type of media large or small you are sharing-IT JUST
WORKS! Business grade Cloud IT services need to be the same! And depending on the complexity of the cloud service offered or
looking to purchase, many still have some way to go in this respect. This paper gives the description of how Facebook use SQL
database for storage purpose and all other technologies that Facebook uses to attract its users. The paper also covers some
concepts of NoSQL (not only SQL), a broad class of database.
