I have completed my engineering 1998. Since then I have worked in different fields from sales to infrastructure, even was part of my family business but I enjoyed most in my last profile as ERP implementation consultant from 2005 december. I was working more as a functional consultant based on my knowledge on the domain. When I decided to explore more on this profile, I did tried to understand the ERP package I was working in terms of the development and maintenance. It was more tempting to involve myself than just lay back and go on doing what I was doing. That is when I decided to improve my knowledge on the software cycle, technical integration of different systems, multitasking, system securities and various aspects of the Software development.
Definitely could have done this in my home country, but decided to explore a new country along with developing my knowledge. Ireland, Dublin and especially Griffith College was providing right combination of education I wanted and in right cost as well. That’s why I am here.
Cloud Computing- Future and it’s Challenges
Cloud Computing- Future and it’s Challenges.

Introduction:
I am going to discuss the cloud computing future and the challenges it is facing now. I have taken two research papers primarily for discussion. First one is Cloud computing Research and Development trend, which was about the principle, style, utility, advantage and finally the challenges and the solution for it. Second one is Cloud computing Security Issues and Challenges, this paper discusses the physical security, issue of switching between the providers, encryption, authorisation issues and impact of dynamic and fluid nature of virtual machine when it comes to auditability of data.
My View:
I certainly agree that cloud computing is the future of computing. Everything is moving towards the virtual sharing and virtual storage. Yes, the future is not without challenges the challenges brings the improvement in the cloud computing.
Reason for advocating the Cloud computing for Future:
The cloud computing started as a promising technology and developed into a fastest growing segment in IT industry [1]. Where everything related to the Information Technology is available in the virtual domain. The user needs to just login to the required website/domain and use the services for a minimal cost without any high quality equipment[2]. The companies like Microsoft, Google and Amazon have started investing a lot on addressing the security issues. The issues they are trying to address are the physical security, issue of switching between the providers, encryption, authorisation issues and impact of dynamic and fluid nature of virtual machine when it comes to auditability of data[1]. The issues related to securities can be addressed by adopting one of the following
- Trusted Cloud Computing based on TCP[3]
- Role Based Access Control Model in cloud computing environment[3]
- Trusted Platform Support Service (TSS)[3]
The other issue is problem of actually allocating the memory of servers in a data centre based on online requests for storage. This is addressed by adopting one of the two algorithms to find the nearest data centre. They are (1) Algorithm HLR and (2) Algorithm CCHLR[4]. The security risks actually vary with each cloud and are dependent on a wide range of factors including the sensitivity of information assets, cloud architectures and security controls involved in a particular cloud environment [5]. The risk management framework gives a better understanding of critical areas of focus in cloud computing environment, to identifying a threat and identifying vulnerability[5]. The framework has seven processes, including:
processes-selecting relevant critical areas, strategy and planning, risk analysis, risk assessment, risk mitigation, assessing and monitoring program, and risk management review[5].
Even with the existing challenges and issues the future of Cloud Computing is very bright.

Book Review: “Delete: The Virtue of Forgetting in the Digital Age” Author :- Viktor Mayer-Schönberger
Book Review on Delete_The virtue of forgetting in digital age
Review on the book “DELETE: The virtue of Forgetting in the Digital Age”
In this book the author is discussing on the issue of we forgetting to forget in this digital age. Things like we post in networking sites in internet and the things we search in search engine getting stored for ages makes things complicated. The author has coated a few incidents like a teacher-in-training, Ms. Stacy Snyder not getting her certificate because of posting a inappropriate picture in face book, and a Canadian psychotherapist, Andrew Feldmar not allowed to cross US border by 2006 because of writing about his experiences with LSD in the 1960s at 2001 in an article, for supporting his cause. By these he is arguing that “Time is a great healer” may not be valued any more.
Forgetting is human, yes, our system is built to forget easily and to remember we need to go a notch up. In this digital era forgetting is made difficult with every bit of the information stored or typed in internet is saved forever. As discussed in the book, flipping through your thousands of photographs taken and deleting few of those is really pain staking instead you can store everything without much effort. These have in a way erased one of the most fundamental behavioural mechanisms of humankind. Author have also suggests a few solutions to the problem of digital unforgetting like scheme of data “Expiration Dates.” and strict privacy laws. He prefers a legal and technical approach in part because getting people to constrain what they desire to share is difficult.
The thought of someone else knowing what we are searching in internet and what we post in social networking sites getting stored forever is bit concerning, yes a bit. The issue is bit blown out of proposition here. Apart from someone intentionally hacking into our account of networking site and posting which we don’t want to and a friend accidentally or even intentionally posts a photograph which we may not please us, there is nothing much to worry. A little self-censorship may do the trick for us. Even in the examples given, the complete picture is not there, like what happened after the Ms. Stacy Snyder sued the board. In my opinion with an eye for the information we share in the internet this issue can be handled well. We had a discussion over this book and the issue it addresses, the outcome was interesting. One thing I want to share here is that when we login to a google account whatever it may be a email account or even a social network, and we search anything in the internet gets saved against out account. It is true, only if we open a google account and search. How many have a google account, even those have google account how many times we open our account and search simultaneously. Another interesting thing which came out of the discussion we had in the class was the voting. 18 voted in favour of the author that there is an issue and 12 voted against it. Other fact is majority of the 12 voted against were from technical background who know a bit about internet and stuffs. There is an issue of information getting stored forever but it is not as serious as mentioned by the author.
Webinar on Implementing Clouds Computing
Hai Guys,
Came across this webinar on implementing Cloud Computing, this also just gives a brief on what is cloud computing and some adv of having it in a company.
Just follow this link for the webinar.

Hay Guys just read news on how google rank their search.
Taught of sharing it, OOps it is almost time for class. Let me get ready.
Google explains how it ranks pages
INTERNET SEARCH GIANT Google has explained how it ranks its search results after attracting increasing scrutiny from regulators.
Under the heading “This stuff is tough“, Amit Singhal, a Google Fellow, attempted to counter allegations of anti-competitiveness by explaining how the firm’s pagerank algorithms work, saying, “Welcome to the wild world of search at Google. More specifically, welcome to the world of ranking.”
As an example of how fair this makes its search results, the firm recommends that you perform a query for “search engines”. Should you try this you’ll find that the top results vary between Dogpile and Alta Vista, however, Euro regulators might need a few more examples than this.
The firm is attempting to counter the recent anticompetition complaints levelled at it, and in a lengthy post, Singhal a twenty year veteran of the search industry, explained that Google’s algorithms are not perfect, but they do work. “After nearly two decades, I’ve lost count of how many times I’ve been asked why Google chooses to generate its search results algorithmically. Here’s how we see it: the web is built by people. You are the ones creating pages and linking to pages. We are utilising all this human contribution through our algorithms to order and rank our results. We think that’s a much better solution than a hand-arranged one.”
Singhal suggested that while other firms take a different approach, this too is imperfect, adding, “Other search engines approach this differently — selecting some results one at a time, manually curating what you see on the page. We believe that approach which relies heavily on an individual’s tastes and preferences just doesn’t produce the quality and relevant ranking that our algorithms do. And given the hundreds of millions of queries we have to handle every day, it wouldn’t be feasible to handle each by hand anyway”.
Google tinkers with its algorithms every day, according to the post, and uses many different ‘signals’ to create its search results. “There’s a ton that goes into building a state-of-the-art ranking system like ours. Our algorithms use hundreds of different signals to pick the top results for any given query. Signals are indicators of relevance, and they include items as simple as the words on a webpage or more complex calculations such as the authoritativeness of other sites linking to any given page,” said Singhal. “Those signals and our algorithms are in constant flux, and are constantly being improved. On average, we make one or two changes to them every day”.
“Ultimately, search is nowhere near a solved problem. Although I’ve been at this for almost two decades now, I’d still guess that search isn’t quite out of its infancy yet. The science is probably just about at the point where we’re crawling. Soon we’ll walk. I hope that in my lifetime, I’ll see search enter its adolescence.”
Happy now, Europe? µ
My first blog here
Hello there,
First time ever starting my blog for academic purpose. End of April 2011 I will be having my MSc in Computing degree. Exited about it. I was warned by my fellow class mates about the course. It’s good to be warned in the begining itself. Will be on guard throughout the course.
