RaDiCe: A Risk Analysis Framework for DataCenters

This release contains the code and data artifacts used to produce the paper "RaDiCe: A Risk Analysis Framework for DataCenters".

OpenDC v2.0

This is the second major release of OpenDC, the open-source datacenter simulation platform. Version 2 of OpenDC enables convenient modeling and simulation of existing and emerging technologies in cloud datacenters.

We started work on OpenDC in 2017, with a great plan and unique vision. We put in total 4 years of science, design, and engineering to reach this point.
OpenDC 2.0 supports workflows, serverless and cloud computing operations, Big Data and machine learning workloads, virtualization and bare-metal datacenters. OpenDC can solve problems of short-term decision making, such as scheduling and auto-scaling, and also, through the Capelin extension, of long-term capacity planning and procurement.
