Not meaning to sound nasty, but if you don't know what the 'cloud' is, then why do you want it? What are you actually trying to accomplish? And if you want to know about the program you downloaded, did you try to read the documentation???

I know you not mean and nasty, thank you for the respond which still not quite related to the question.




If anyone knows the answer of my question, will be great and appreciated.

Again, question = howto start the apache cloudstack program/services installED to have a look? I don't even know the command to open it?

TB0ne has a point

a "cloud" is basically something dreamed up by AN AD AGENCY !!!!( think "Mad Men") as a "catch phrase "

from your post you DO NOT know what "it" is

are you running about $1,000,000 or MORE in blade servers
and have 120 or more PAYING clients for the servers
and do those customers ( computer and processing ) needs vary from day to day
so much so that you HAVE to hire MORE STAFF !!!

if so
then a "cloud" solution might be needed
it can REPLACE THAT STAFF you had to hire
because it will AUTOMATICALLY adjust the servers and the VM'ed servers to meet your PAYING clients NEEDS

by allowing you to ONLY charge then for JUST what they are using
and THAT saves them CASH

and saves YOU cash by only using the electricity that is NEEDED at that time -- saving YOU CASH !!!!!!

basically it is a REHASH of the 1970's
( disco - got to love it )
Mainframe and clients on a time share

the "cloud" part is a software improvement on the "time share"


an example :
lets say you are a small Accountant
come April you ARE BUSY
very busy around tax time

so busy that you NEED a ton of processing power, storage space, bandwidth, and servers to handle all the work

now it makes NO business sense to pay for all this ALL YEAR AROUND
you only need that much for 2 months of the year
so for the other 10 months you only pay for the 1/4 of the "cloud" space and use
but for those 2 months you par 4 times for 4 times the computers

Again, you need to READ THE DOCUMENTATION. I even looked it up for you, and gave you a link. Did you not read/understand it? It tells you how to install it, start it, check it, and program for it. How much more do you need to be told?

And being given complete documentation IS 'related to the question'. And again, what is your goal? What are you trying to accomplish? If you don't know what this software is, what it does, or how to use it, why are you installing it????

All rite, time to responding... after researching...

The term "Cloud Computing" refers to the on-demand delivery of IT resources via the Internet with pay-as-you-go pricing.

Let's have example of well known hosting service providers first, like GoDaddy.com and Amazon.com. GoDaddy offering many choices usually paid by monthly or annually. And now the latest cloud service providers, they would charge flexibly, the service fee can count in per day even per hour!

So I feeling that's tougher to the IT professional.

Oh? Why is that? And 'research' usually involves more than one source...what you posted is verbatim from the Amazon AWS page, which is only ONE type of 'cloud computing'.

to protect machine, let it rest for hours like following

RewriteEngine on
RewriteCond %{TIME_HOUR}%{TIME_MIN} >0200
RewriteCond %{TIME_HOUR}%{TIME_MIN} <0400
RewriteRule .* - [F]


I still believe cloud meaning apache web server.
you visit a machine.. inside got some content to read

No...that's a WEB SERVER. You visit the site, and have content. AGAIN, 'cloud' has little meaning in how you posted this (vague) question. A 'cloud' application could mean:
  • A storage device that is virtualized between MANY machines (or just one), and is accessible over a network.
  • A parallel-computing system that 'virtualizes' the entire system, meaning to add more CPU to an application (which is the 'cloud based' application), you stick another machine into the cloud.
  • A service that is virtualized over a network, like a print-on-demand system
  • ...ANYTHING else that can be used over a network. Things like Netflix? Hulu? Google Play? Amazon AWS? S3? ALL of those are 'cloud' systems.
You still haven't read much about what a 'cloud' is, and after a year, you should have at least some basic understanding, other than "it's a web page".

If you really want to understand what cloud computing is then I would suggest reading this. It is not vendor specific and clearly defines what cloud is.

Cloud is really a fancy term which people like to flaunt / brag about. I have been there and I can say that there is not much difference and it is more of marketing.

In simple terms it is pay and use stuff. Will it make a difference if you rent a house and pay for it or you own a house (Please don't start that owning a house is an asset, it is just an example)? Ultimately you are using the house. Similarly in cloud you pay for what you use. You are using a VM hosted on their server you pay for it, you need DR (disaster recovery) you pay for it, you need additional space you pay for it, you need managed services you pay for it and the list goes on.

No, cloud does not mean apache web server. Web service is just part of it. It is used as an interface to give user access to dashboard where he can check the current status or request for new stuff from cloud host.

It will be good if you have a look at the links provided by other members and the wiki link which I mentioned in this post. Once you are through the discussion will be more fruitful and interesting.
