Isn't it just another fancy and overhyped term we hear in the world of computing/IT ?

IIRC, there was a dilbert strip on it as well.

imho, its not really a 'cloud' as of now. it is just that they have newer billing system for same old 'virtual private server' technology. they sell/market cloud using the analogy of your electricity service provider but when you get down to details, you are buying VPS hosting with fancy billing systems.

Use of www.team-bhp.com is an example of cloudcomputing.

Refer to open cloud manifesto here Open Cloud Manifesto Resources. This site lists some of the things implemented and road ahead for cloud and dispels many myth on the subject while trying to standardize the concepts.

There is a concept of public cloud, private cloud, community cloud etc and the concerns for security (or lack of) is no different than any other networked application that we use which transgress the physical walls of our house/enterprise.

I guess the concept is familiar to you now...

Been working with the "Cloud" for almost 3 years now, ever since S3 debuted although it wasn't in the exact sense a Cloud. The "nuts & bolts" of the "Cloud" is pretty darn interesting & it's indeed come a long way. Anyway, Amazon's EC2 is one of the best Cloud providers, at this point in time. Not all Cloud vendors are equal, & you'll have to pick & choose wisely, & at times, even EC2 can be flaky. Used judiciously however, you can save quite a bit on infrastructure costs - especially if you're into simulation, CFD, & stuff where high-end hardware is a necessity.

And yes, security is one of the major stumbling blocks in the path to greater adoption of the "Cloud" - but again, it all depends on the sensitivity of the data that you're moving to the Cloud. There are a few security task-forces & alliances who are working to make the environment more secure, but it's still early days. If you think a "public" Cloud is too insecure an environment, you can opt for a "private" Cloud (1 & 2), or even a "hybrid".

Things have come full circle now - well almost. From mainframes & dumb-terminals, to 2-tier, 3-tier, & n-tier systems, we're back with net-tops & Chrome-OS - heading inexorably down the way everything started

Guys,I have understood this. But is cloud computing different from SaaS?
If so,what is the difference between cloud computing and SaaS

Cheers.

Software as a service (SaaS, typically pronounced 'sass') is a model of software deployment whereby a provider licenses an application to customers for use as a service on demand. SaaS software vendors (such as CyberShift or SalesForce.com) may host the application on their own web servers or upload the application to the consumer device, disabling it after use or after the on-demand contract expires. The on-demand function may be handled internally to share licenses within a firm or by a third-party application service provider (ASP) sharing licenses between firms

SOURCE: Wikipedia

TO make it more easy for you: Cloud computing is when you rely on third parties for Server space (a data center is the best example, where your servers/data are located off site). You actually become a thin client(may or may be not 100%).But in case of SaaS you "borrow" a software application or a user license for your needs. once that need is fulfilled, the company who lent you the software pulls back your access. Advantage of this technology is, if you need an expensive software for a short term and don't want to blow up your pocket, SaaS comes into picture. Its software on demand. Just like TV-on-demand where you can watch till you have subscription. Once your subscription expires you get no signal.

As mentioned in the explanation I posted, the software may be loaded onto your pc or may reside on a server on internet where you can access it remotely.

Hope this'll help.
Regards
Punzabi.

I was always fascinated by this term “cloud computing”. Never got chance to check out what it is. But when I read one of the post here which says, there will be nil or little CPU usage and all high end processing will be done by back end system. Now this is essential same as mainframes

As samurai said its old wine in new bottle. Essentially a 3270 Mainframes screen converted to modern Color screen

people,

any one has worked on migrating mainframe apps on to cloud. Please provide some pointers! also the advantages/dis advantages?

Microfocus is planning to make Cobol as language of choice for Windows Azure OS of Microsoft! (like Python by Google and Ruby by Amazon)
Looks like we are going back in ages with Cobol coming to life again

One more point why vendors like it. No piracy with Cloud Computing! How will they address the privacy issues I do not now, since data mining will be much more of a threat. As someone wrote today on another forum - Probably Google knows more about you than your wife!
