Test drive on the cloud using Amazon web services.

I wish to write a couple of lines on working with the Amazon Elastic Compute Cloud (EC2) today.
Of course, visiting the aws website would be sufficient for one to understand how things work there, this one’s some kind of a primer! Outlines what’s there in the store!

Getting a server up and running is as simple as 1..2..3…

1. Register
2. Choose and Submit payment info.
3. Create an instance (choose your server configuration), and launch.

The server configuration may be chosen manually, or from a list of “Community instances” (pre-configured).

The server, with all the resources you’ve requested along with the OS, and other application softwares like Oracle Database or SQL Server, is delivered in a jiffy – as fast as you click the launch button!

Amazon Web Services provides you with a private-key file using which you can login to the instance. All other tools like those to monitor the resource usage are readily available to choose and use.

Technical team that a cloud demands:

The cloud not only brings about a revolution across small and mid-sized businesses, but also creates a shock wave in the fields of Infra Structure/Networking/DBA man power.

It happens this way…
Say, a company Xyz Pvt Ltd of India is to host its online sales and eCommerce website where transaction volume per day is about one million. The company is unable to afford a million dollars in purchasing a server, with-out which the database/app-server in no way can handle about a million transactions per day. A Cloud enables the company to do this.
With the advent of Cloud computing, the company can now pay about a 100 dollars per day and host its website on the server capable enough.

This is only a small illustration where Cloud computing helps small and middle scale companies. Now if there are about tens of thousands of such companies in a city like Hyderabad [India], atleast thousands of them would come up with their own websites like eCommerce/online sales/customer survey, where there were only a few earlier.

Now let us change our perspective, let us have a look from a company that offers this cloud, say Abc Pvt Ltd, from India. Say there are about 50 to 100 companies using the cloud offered by Abc. Abc has to see that the cloud it offered is up and running all the time. If it is offering about 100 high-end servers for its customers, imagine the workforce it would need to look after them.


Cloud computing: A revolution to come

I would like to make my comments on Cloud computing. As an admirer of technology and sciences, and more as a professional in computer software engineering, I have been reading articles about cloud computing on the web.
The meaning, importance, power and almost every other thing that relates to Cloud computing can be understood from the very name. It is self-explanatory.
Hee, the objects (software/hardware) are available in the form of a cloud, which any authorized user can access. It is sizeable, on the go; one can upsize or downsize their server as easily as they post a message to his/her friend on a social networking site, no wires, no cables, no power and obviously no hassles, no worries.

Today, there are many Independent Software Vendors, we will call them ISVs hereafter, who cannot afford full sized web-servers and database servers for the applications they develop. For the costs of their procurement and maintenance are too high and far, really far beyond imagination. That said, another reason for their not procurement of their own servers is scalability.

Now that this part is taken up by the provider of the cloud, the ISV must now pay only for the machine, and that is based on the time he uses it for!
Now suppose that there are about a 100 such , and with the advent of the cloud computing, suppose that 50 of them will host their applications on their own servers.
Now the purpose or domain of these applications is what brings competition among these 50 ISVs.
But let me interrupt the narration about these 50 ISVs and ask you a simple question, do you think it is only 100 such ISVs in this real world? No. Millions are there. So imagine the competition and the revolution that is to come.

A picture is worth 1000 words… A video is worth a thousand pictures…
