#IJSRD Private Virtual Infrastructure (PVI) and Locator Bot


Also addressing the security and confidentiality issues surrounding cloud computing is University of Maryland, Baltimore County researcher John Krautheim. His proposal is aimed at better sharing the risk responsibility between the cloud provider and customer, giving the customer much more control than is typically the case. "A method of combining the requirements of the user and provider is to let the clients control the security posture of their applications and virtual machines while letting the service provider control the security of the fabric. This provides a symbiotic security stance that can be very powerful provided both parties hold up their end of the agreement,"

#IJSRD Astrophysics and Space Sciences


Physicists in the McDonnell Center for the Space Sciences use experimental techniques of high-energy physics, observational techniques of astrophysics, and the laboratory study of extraterrestrial materials to address a variety of astrophysical problems. These include the origin of cosmic rays, energetic processes in galactic and extra-galactic objects, the synthesis of heavy elements in nature, the formation of dust around stars, and the history of the lunar surface and of meteorites.

How Does Whatsapp Generate Revenue? #ijsrd

Whatsapp: The leading OTT messaging service. There is always a prominent question baffling every user’s mind – How is Whatsapp able to make money when its services are free of cost?
Whatsapp enables it’s user to send text messages, images, video and audio media to other whatsapp users. The said service is available on iOS, android, Symbian, blackberry OS and windows platforms.
On a different note, we know Facebook has recently bought Whatsapp. Do you want read about it? Read about it here! Just follow the link!
Okay, back to business now!
Whatsapp is earning its revenue through two different ways:
1) Subscription Fee: Whatsapp allows it’s user to enjoy Whatsapp services for free for first year. However, after that it charges $0.99 for continued service. But till date, I have not heard of a single person who has paid for this service. Interestingly, Whatsapp tend to extend the free service period every time a user reaches close to the expiry date.
So this method of revenue generation that seems like the only visible revenue generation scheme is actually not generating the revenue for Whatsapp.
2) According to my speculation, the revenue generation for Whatsapp is primarily through database management. All the conversations on Whatsapp are backed up on Whatsapp servers constantly. Our conversations reflect our interests, likes, dislikes and majorly depicts our preferences. This information is invaluable to big firms where relevant tailor made products can be offered after data sorting.
Let’s take a deeper look into this!

Whatsapp users have been ever increasing since launch currently numbering out users on any other competitor.
Given such high number of users, the number of messages exchanged per day is also incredibly high in case of Whatsapp- peaking as high as 11 billion. With such extensive information available on Whatsapp backups, the big companies are willing to pay handsome amounts for information extraction.
This data management scheme is merely a speculation. As evident, Whatsapp is not involved in ad marketing. Any Whatsapp user can vouch for the fact that Whatsapp does not support advertisements. Whatsapp’s CEO Jan Koum clearly states that Whatsapp is meant for instant messaging and forcing advertisements would disrupt the sole meaning of Whatsapp and instant messaging. There is no way to justify the data management ideology, but then there is no other justified revenue model as well in the store.
