Public Cloud Computing : How Public Cloud Works

Public Cloud Computing falls under NIST standard cloud computing model and Public Cloud Computing hosted storage or apps can be accessed over the HTTP protocol. The usage of on demand servers hosted on public cloud computing platform has not been increased as was expected over the past two years by the Multinational brands with root in U.S. (North America), Europe (Germany) and Asia (India). For India, quite unexpectedly, Server Colocation based data center has been expanded but not that of Public Cloud Computing, during this period. One of the reason is, if you want to get good quality information on Public Cloud Computing over the Internet, except our one post on Public Cloud Computing (Risks of Free Cloud you are using) all are actually commercial service providing websites. So, in this article we will go deeper on Public Cloud Computing.

What is Public Cloud Computing ?

From the point of technology, Public Cloud Computing is nothing special, it works in the same way like our ‘usual’ Cloud Computing works. The only differentiating point of Public Cloud Computing with (specially) Private Cloud is that – in case of  Public Cloud Computing, any user is allowed to access a part or full of the data it contains, over the traditional HTTP connection, that is, over the Internet.

So, Cloud Computing SaaS can easily be deployed and needs no explanation.

What are examples of  Public Cloud Computing ?

This webpage has several live examples of  Public Cloud Computing ! The webhost is The Rackspace Cloud – the Server of this webpage page, the Akamai CDN, Load Balancers – all are practical examples of  Public Cloud Computing. Google AppEngine is another such example.

Why you have said before that Free Public Cloud Computing has risks ?

Yes, we have rightly said that Free Public Cloud Computing has risks.  Here we are mainly talking about the paid solutions, although Public Cloud Computing theoretically covers both paid and Free solutions. As with paid Public Cloud Computing solutions, you have more control through API, .htaccess files etc. which part you will allow to access everyone and which not. For example, our wp-admin directory is on a Public Cloud Computing solution, but its  access is restricted.
