History has a funny way of repeating itself, or so they say. But it may gives some surprise to find this old cliche applies just as much to the history of computers as to wars, revolutions, and kings and queens. For the last three decades, one trend in computing has been loud and clear: big, centralized, mainframe systems have been "out"; personalized, power-to-the-people, do-it-yourself PCs have been "in." Before personal computers took off in the early 1980s, if your company needed sales or payroll figures calculating in a hurry, you'd most likely have bought in "data-processing" services from another company, with its own expensive computer systems, that specialized in number crunching; these days, you can do the job just as easily on your desktop with off-the-shelf software. Or can you? In a striking throwback to the 1970s, many companies are finding, once again, that buying in computer services makes more business sense than do-it-yourself. This new trend is called cloud computing and, not surprisingly, it's linked to the Internet's inexorable rise. What is cloud computing? How does it work? Let's take a closer look!
Cloud computing is one of the hottest technical topics today, with broad-ranging effects across IT, Information Architecture, Business, Software Engineering, and Data Storage.
Cloud Computing: What It Is—and What It Isn't
In traditional computing, many software programs can be run on their own. The documents can be created, run, modified, and accessed from other computers in the network. The documents cannot be accessed from outside the network. The whole scene is PC-centric.
By the invention of cloud computing, the programs in the computer are run on the internet. If any problem occurs in the computer or the computer crashes all the information and the software are saved in the cloud. It is document centric.
This book has been written for the BE/B.Tech students of All University with latest syllabus for ECE, EEE, CSE, IT, Mechanical, Bio Medical, Bio Tech, BCA, MCA and All B.Sc Department Students.
The basic aim of this book is to provide a basic knowledge in Cloud Computing.
Cloud Computing for engineering students of degree, diploma & AMIE courses and a useful reference for these preparing for competitive examinations.
All the concepts are explained in a simple, clear and complete manner to achieve progressive learning.
This book is divided into five chapters. Each chapter is well supported with the necessary illustration practical examples and solved problems.
