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 [...]
