Consumption, Utilization and Elasticity: Cloud Basics

Cloud Utilization Heatmap by Newvem

Lets start with a basic scenario where there is a sudden peak in the demand for an application service as the amount of clients’ requests increase. This event leads to a direct and immediate impact on the load placed on the web servers that host the service. In the traditional world, the number of servers is fixed, therefore an overload adversely affects the application performance and the service may slow down or even be terminated. The IT team would want to restore the environment functionality and bring the service up as soon as possible. The immediate impact  of such an event on the business can be devastating. Starting with this simple understanding, we can move into the world of cloud computing use including resources consumption, while relating to the key differences between the traditional data center and today’s cloud technologies.

Private Cloud Interview with Mr. Joe Weinman


As the founder of Cloudonomics.com, Joe Weinman is one of the most known cloud computing evangelists in the world. Weinman researches the economics of the cloud. Among other cloud aspects he examines, he also relates to the cloud financial operational costs together with its buisness benefits. Following I Am OnDemand last posts summarizing and discussing several Cloudonomics researches, we asked Mr. Weinman to meet for a brief discussion. Last week I had the honor to interview him for about an hour and hear his clouds’ perceptions and vision.

Hybrid Cloudonomics – Part 2


The first part of Weinman’s lecture discussing the basic “go to the cloud” and demonstrating cloud environments’ loads of different corporations’ web applications. In this part we will bring 6 scenarios presented by Weinman, each includes a brief analysis and proof of its cost and benefits.

First lets start with several assumptions and definitions:
> > > 5 Basic assumptions Pay-per-use capacity model:

  1. Paid on use – Paid for when used and not paid for when not used.
  2. No depend on time – The cost for such capacity is fixed. It does not depend on the time or use of the request.
  3. Fixed unit cost – The unit cost for on-demand or dedicated capacity does not depend on the quantity of resources requested (you don’t get discount for renting 100 rooms for the same time).
  4. No other costs – There are no additional relevant costs needed for the analysis.
  5. No delay – All demand served without any delay.

6 Key Essentials for Hybrid Cloudonomics: a Lecture by Joe Weinman

Joe Weinman is well known in the cloud computing community as the founder of Cloudonomics. Presenting complex simulation tools, Weinman characterizes the sometimes counterintuitive business, financial, and user experience benefits of cloud computing including its on-demand, pay-per-use and other buisness aspects. Last month I had the pleasure of participating in Weinman’s webinar. Weinman discussed several interesting points which I would like to share with you.

Weinman started by contradicting what seem to be the fundamental assumptions regarding the Cloud and its benefits. There was nothing radical about what I heard but it made me think and challenge all the things I took for granted –
