cloud computing

Vikash,

Here's an excerpt from another interesting and relevant article (http://cloudcomputing.sys-con.com/node/581838):

-----Excerpt Starts-----  

In 2003 the late Jim Gray published a paper on Distributed Computing Economics:  

Computing economics are changing. Today there is rough price parity between  

(1) one database access,  

(2) ten bytes of network traffic,  

(3) 100,000 instructions,  

(4) 10 bytes of disk storage, and  

(5) a megabyte of disk bandwidth. 

 This has implications for how one structures Internet-scale distributed computing: one puts computing as close to the data as possible in order to avoid expensive network traffic.  

The recurrent theme of this analysis is that “On Demand” computing is only economical for very cpu-intensive (100,000 instructions per byte or a cpu-day-per gigabyte of network traffic) applications. 

 Pre-provisioned computing is likely to be more economical for most applications - especially data-intensive ones.  

If telecom prices drop faster than Moore's law, the analysis fails. If telecom prices drop slower than Moore's law, the analysis becomes stronger. 

 -----Excerpt Ends-----

Cloud computing as a concept is a laudable one! Like other concepts, this also carries some demerits. I can not take this as a "one stop solution" from one vendor. The major vendor, say, Microsoft, should tie up with a number of software services companies (as SaaS providers) to offer "a la carte" offering as per the customer's requirement with a strong SLA from one Vendor (i.e. Microsoft). Otherwise, as Mr. Joydeep mentioned, this is like hiring a taxi for a specific distance, finish your work, and hire another taxi to return to your destination! Alternatively, this looks like the Information & Broadcasting Ministry is asking you to contend with "Free to Air" Channels, if you don't want to pay to get entertained by MSOs!

I love you Anna, a car is a Taxi, a Taxi is a Car similarly

Mass converts to energy (photon), energy converts back to mass (photo eletricity)

There is only & only one Kalidas rest are morden kalidass :(

It has taken me more than a decade to reach where I have reached, virtualization existed on Mainframe (Unix) when 8086 came to market bill was a school boy then. Do you still feel I am separatist ?

Joydeep dada,

Feeling bad? :D Don't worry - we all make mistakes sometimes, even I. [But I try to edit well. Ha ha ha!]

And yes, a car can be a taxi in the same way, a taxi can be a car. You have chosen quite the the wrong thing to be picky with. 

Also, your remark about education sounds too separatist about South India versus North India. Kewl dada! There's no need for all that.

Further, what does the equation (mass–energy equivalence) have to do with this topic? Do enlighten us.

And finally, the word is "m o d e r n" and NOT "Morden".

And really finally, the name "Kalidas" should be spelled with a capital "K".

Dear Isaac I know it’s Madhavan (Krishna) is car and Taxi the same?

Look dear E=mc2 is three letters one numerical, with an operator, you reach here after 10 academic years if you choose science else null.

Well in South education has become pay and buy (certificate) some four decades ago; Your opposing!!! How come?

Major (retired) Rajendran Mariagnanam pleases assist our young Isaac, the Morden kalidass !!

I beg to differ, Joydeep.

I would like to point out a couple of things:

It is NOT clear which side you are supporting.

The very first post by Major Rajendran Mariagnanam has a link to a video with an excellent explanation for laypersons, in addition to his good explanation.

Please read his explanation and watch the video before you make any comments.

By the very analogy that you gave - to the customer - there is no need to possess a car i.e. the hardware (and the software - no need to drive, so no driver).

Similarly, the cloud is a replacement for hardware and software too (no need to maintain software licences - which is a relief to many). 

However, I agree with Vineet Thakkar: There might be some things (services, data, etc) that you would like to or maybe should keep to yourself.

I support your views JOYDEEP sir ....actually one can define cloud-computing as a pay-per-use model for enabling on demand access to reliable and configurable resources that can be quickly provisioned and released - with minimal consumer involvement in terms of management ....you pay only for the resources you use ...you need not set up the infrastructure or buy the software....so there's no question of replacing hardware...

Joydeep very well explained.

Thanks for inviting me to this debate .I do agree with you that the hardware is replaced by cloud computing .

There are two aspects to it. one is the hardware the software that processes enables the customers to see through cloud computing technology.

However the other aspect of the privacy maintained in respect of the data base or the content security is of prime importance wht many in these days feel its importance.

With more hacking through computers and also through manual hacking customers are very warry about cloud computing.

No doubt it is cost effective and also very collaborative.

Cloud computing is  very good tool for knowledge based sharing learning like the Wikipedia and so on which has open source activities.

If the routing of the critical information of privacy and secret through some means through cloud computing without its storage at any cloud computing terminals or its deciphering of information keeping its and originality then the cloud computing is the only answer.

The software that could be hosted on cloud computing should be pay per use methodology without any analytics of its use by clients .then this is useful for customers.

At no point of time there should be no storage of any information that streams from one customer terminal to another customer terminal through cloud computing which will be valued by customers.

These are the few mentioned points i think should make the cloud computing make the hardware replacement at many places and if it is used as just as transit points that a traveler takes while holidaying from one tourist spot to another without owning it but just paying a fee for its utility.

Hosting of users data of any sort should be restrained and then the cloud computing is useful to all.

Your point of hardware being replaced will be in its true sense like we  all have just computers at our homes and have to buy soft ware to run it depending on our choices.

Major(retd) Rajendran
