Web applications
The first thing we need to talk about or time out cloud computing is the
simplest form of cloud computing and
that is web applications. What web applications are? These are applications
that you use that have been created using standard world wide web technology. So basically the applications that have been
created using HTML JavaScript XML PHP etc.
Now why these four are a form of
cloud computing is because when you use these web applications you are actually
accessing applications that are sitting on another server , using the web
browser that is installed on your computer. So this is like if you're looking
at Google Docs ,Google Docs is a classic web application. So you sit down at
your computer and you open up a web browser and then you go to the Google Docs
website login to your account and then you can start writing documents. Basically
as if the application was installed on your own computer so again talking about
separating applications from operating systems from hardware why this is cloud
computing? because now that office
software that you were using is no longer installed on your computer .So if
your computer crashes or if your computer fails for whatever reason you can step
to the side, go to your neighbor's computer get on and finish whatever
paperwork that you were trying to do. The basic thing to understand with most
web applications is again these are neither created or written in standard web
programming languages again like
JavaScript,XML,Html etc. These are pretty simple piece of software you know
you're looking at you know Google docs or excel spread sheet, I think it is one
of those things but basically you're doing relatively simple things QuickBooks
online is the web application .The idea behind is again is if your operating
system fails, If your computer fails etc you can still access all of your data
and complete your work simply by going to another computer so that's the basic
concept that web applications. Again we're going to be talking about
application servers but there are web applications in there and are different.
