Voxxed Days CERN 2019
on Wednesday 1 May
Daniel is a software engineer working at the group responsible for service delivery and evolution of Compute, Monitoring and Infrastructure tools services for the CERN Tier-0 Data Centre and the Worlwide LHC Computing Grid (WLCG).
In 2012, at CERN we started the deployment of our private Cloud Infrastructure using OpenStack. Since then we have moved from a few hundred cores to a multi-cell deployment spread between two data centres. After 6 years deploying and managing OpenStack at scale, we now look back and discuss the challenges of building a massive scale infrastructure from 0 to +300K cores. With this talk we will navigate through the history, architecture, tools and technical decisions behind the CERN Cloud Infrastructure.
