Python library for calculating cloud costs.

Within SITIO project we developed several tools for calculating and predicting costs of running IT systems on various clouds. Recently we open-sourced one of such tools – python library ‘cloud-calculator’. Source is here: https://github.com/HEP-KBFI/ccc . Using easy_tools it can be installed as easy as “easy_install cloud-calculator”. In this blob post we show sample usage of […]

Risks and rewards of moving applications to the cloud – a white paper

We have recently come across an interesting discussion group called “Cloudusecases.org”. It has published two white papers titled “Cloud Computing Use Cases White Paper” and “Moving to the Cloud – Risks and rewards of moving applications to the cloud“. Both papers are very interesting and informative. Especially the second one suggests the following very straight […]

To cloud or not to cloud – as a function of WAN costs

Amid the hype around cloud computing and the millions of dollars pumped into marketing those utility computing services, not every business operation will benefit by moving to the cloud. So as the dust of the hype clears, we are left with the question of whether to cloud or not to cloud. This is a question […]

First Desktop-to-Cloud Job Execution

Minor success! This past week we ran our first real-world experiment on EC2 using the under-development D2C tool. The desktop tool transformed VirtualBox 64bit Ubuntu images to AMIs and launched 4 EC2 instances. Manual intervention was required to start the actual program conducting the experiment, as “auto launch” is not yet an implemented feature of […]

Comparing Cloud Computing Prices

During our research we have recently come across an interesting blog with the title “The Case for a Cloud Computing Price War”, where the author  Daniel Berninger argues that Amazon has kept prices for its EC2 offering stable over years, without handing over price performance improvements to its customers. The article further on argues that […]

Creating a 64 bit EC2 Image

Recently a researcher we are working with gave me an VirtualBox image to deploy on EC2 with the fledgling “Desktop-to-Cloud” tool. Discovering that it was 64bit, I had some additional work on my hands. Up until now the migration tool had assumed all source images are 32bit. No problem, I thought, there should only be […]

VM to EC2 Migration Lessons

The following are a few lessons learned about migrating a VM to EC2 in the past 2 weeks. These notes are particular to dealing with an Ubuntu VirtualBox image. Hopefully they will provide some tips/guidance to others who are undertaking the same task. 1. Transforming a VM image on OSX can be very cumbersome / […]

Cloud Computing and the Art of Sourcing

In the book “The Big Switch” Nicholas Carr makes a historical analysis to build the idea that the data centers/Internet is following the same developmental path as electric power did 100 years ago. At that time companies stopped generating their own power and plugged into the newly built electric grid that was fed with electric […]

Profit-Aware Server Allocation for Green Internet Services

In recent years large investments have been made to build data centers, or server farms, purpose-built facilities providing storage and computing services within and across organizational boundaries. A typical server farm may contain thousands of servers, which require large amounts of power to operate and to keep cool, not to mention the hidden costs associated […]

Maximizing Cloud Providers Revenues via Energy Aware Allocation Policies

Cloud providers, like Amazon, offer their data centers’ computational and storage capacities for lease to paying customers. High electricity consumption, associated with running a data center, not only reflects on its carbon footprint, but also increases the costs of running the data center itself. In “Maximizing Cloud Providers Revenues via Energy Aware Allocation Policies” we address […]

Desktop to Cloud Introduction

Scientists and researchers may develop number-crunching programs on a personal machine, but lack the technical means to scale the architecture to deal with meaningful datasets efficiently. I would like to introduce the “Desktop to Cloud”, a project recently begun that aims to address roadblock. Our goal is to provide tools that push and expand an […]

Costs for running scientific applications on EC2 significantly higher in comparison to in-house infrastructure

We have recently written a scientific article on “Towards a Model for Cloud Computing Cost Estimation with Reserved Instances”.  Cloud computing has been touted as a lower-cost alternative to in-house IT infrastructure recently. However, case studies and anecdotal evidence suggest that it is not always cheaper to use cloud computing resources in lieu of in-house […]
