- Comparing prices of cloud computing providers
When considering ROI maximization of cloud computing solutions it is crucial to minimize costs of cloud hosting, especially that differences can be very big. Anyone who has tried to compare prices of IaaS providers knows that it is a very tedious task if done manually, since there are different pricing models used, there are subscription [...]

- On delivering reliable services using spot instances
In the Infrastructure-as-a-Service (IaaS) cloud computing market, spot instances refer to virtual servers that are rented via an auction. Spot instances allow IaaS providers to sell spare capacity while enabling IaaS users to acquire virtual servers at a lower price than the regular market price (also called “on demand” price). Users bid for spot instances at [...]

The cloud computing economic model is expected to bring significant rewards – apparently. Those rewards may be possible but the quality of analysis to demonstrate that the cloud paradigm will yield an ever-growing margin is far from assured. The assumptions underlying the economics of the cloud are tenuous and therefore the promotions and promises should [...]

- Cloud economics penalizes large workloads
Cloud computing is heavily promoted as the low-cost alternative to in-house data centers. Yet this is not true for any context and any application. A recent paper with the title “To Move or Not to Move: The Economics of Cloud Computing” by Byung Chul Tak, Bhuvan Urgaonkar, and Anand Sivasubramainam states that especially applications with [...]

- 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 this [...]

- Cloud Computing; Freedom of Choice?
Shortening time to market, increasing transaction volumes, 24 x 7 business, all at lesser costs puts a burden on the information processing of organizations. How should one adapting to the increasing complexity and changes of the organization and its environment? The new delivery model for information processing, Cloud Computing, with an on-demand provisioning of computational [...]
