One of the Better “Cloud Computing” Posts that I have Read

Wednesday, February 20th, 2008 by

Alex_Iskold_graphic As I strive to better understand these new emerging technologies such as “cloud computing”, I frequently find myself reading various blog articles, many professing to be the end-all definition related to the topic. It is not very often that I actually come across an article that is informative, understandable and compelling enough to warrant note.

The post by Alex Iskold is a perfect example of one of these excellent articles. An important definition from his post:

The idea behind cloud computing is simple – scale your application by deploying it on a large grid of commodity hardware boxes. Each box has exactly the same system installed and behaves like all other boxes. The load balancer forwards a request to any one box and it is processed in a stateless manner – meaning the request is followed by an immediate response and no state is held by the system. The beauty of the cloud is in its scalability – you scale by simply adding more boxes.

Some may say that this article is a bit “heavy” on Amazon as the “killer service.” But I believe his point is that Amazon has put a lot of weight behind and person-hours into their products and they will be hard to duplicate, at least for players developing “cloud” products. But some of his general comments hold true regardless of the product: “Free from the need to solve the scalability problems, startups are able to focus on the specific problems their product or service is trying to solve.”

I recommend this as a good read on what Cloud Computing is, a la Amazon, and for people really trying to make heads or tails of grid, utility, cloud and distributed computing.

Understanding “Clouded” Computing Terms (revised)

Tuesday, February 5th, 2008 by

Author’s Note: This post was revised on 6/23/08. The nature of computing is under going a revolution and rather than fully remove this post, I elected to refresh it so as to provide a better framework for readers.

There seems to be a lot of debate around different types of Computing Terms being used to describe server and hosting solutions. In fact, in the past, the blogosphere seemed to throw around terms like Grid, Cloud, Utility, Distributed and Cluster computing almost interchangeably. But, as of this revision, one term is rising to the top: Cloud Computing. (See recent trend analysis here.)

The definitions vary from source to source, author to author. While I cannot (and will not) attempt to articulate the end-all definition, I can write about how I view these terms and how they apply to the products that we offer, namely GoGrid. But before I dive into MY interpretation, providing what others view on these subjects may shed some light on our framework.

Terms as defined by Wikipedia

wikipedia_logo_sm Many people view Wikipedia as an authoritative source of information but that is always subject to debate. Wikipedia defines some of these terms as follows (not the end-all definitions though) and I have taken some liberties of removing non-relevant information for argument’s sake:

  • Grid Computinghttp://en.wikipedia.org/wiki/Grid_computing
    • Multiple independent computing clusters which act like a “grid” because they are composed of resource nodes not located within a single administrative domain. (formal)
    • Offering online computation or storage as a metered commercial service, known as utility computing, computing on demand, or cloud computing.
    • The creation of a “virtual supercomputer” by using spare computing resources within an organization.
