Question by Veli: What is Cloud Computing? Layperson giving 10 points?
I am from literature background with basic understanding of the Net and a few of the office software. I do not know if an application software and operating software are two different things or one.
Here are a few of my questions, please explain just the basic idea,
Can it be installed on a personal comp? Most forums talk about companies so…
If it works on a common platform (platform meaning not the way programmers understands it but a layperson, since they say it works on a common network) how will this affect the security?
In the current state of affairs, if my computer is disconnected from the internet, i can still keep my work on, on a word or excel sheet; since cloud computing is entirely web-based, what will happen to my work, if the cloud comp gets disconnected?
Answer by Zarn
Cloud computing is using internet connectivity to access computing services not present locally. An example of this would be Dropbox, or Google Docs. In a sense, Steam would also be an example of cloud computing, as would Facebook and other social media.
Cloud computing would ordinarily not be installed per se on a personal computer, but a client can be installed on a personal computer to gain access to cloud computing.
Security is an issue, as is data lock-in. There’s no layperson explanation available there – it would concern such things as cryptography (both symmetric and asymmetric) and various cryptographic attacks.
If a computer using a cloud based service gets disconnected, there are two ways this can be handled. Either the computer starts buffering data (in order to transfer them once connectivity is restored – Dropbox does this for instance), or the computer shuts down the service (because connectivity is interrupted – Facebook does this).
Cloud computing isn’t necessarily _web based_ per se, it is actually based on _internet connectivity_. Two different things, though the difference is usually too subtle for a layperson to discern, so I won’t go into detail there.
