Vangelis Koukis
TrackTrack 1
DescriptionThis talk will introduce Synnefo, a complete open source cloud platform. Synnefo powers GRNET's ~okeanos public cloud service, an IaaS cloud delivering advanced compute, network and storage services to the Greek research and academic community, since 2011.
 
The talk will cover our experiences with building and running a large-scale production public cloud, focusing on:
  * Open source vs. commercial software in building a large-scale, production cloud infrastructure
  * Building on commodity hardware vs. vendor solutions  
  * Current open source solutions
  * Identifying the building blocks of an IaaS cloud, and re-using existing opensource components wherever possible
  * Why Synnefo?
  * General Synnefo architecture, software components used
  * Running robust, fault-tolerant VMs without a Storage Area Network
  * Using a content-addressable file storage service as the Image repository
  * Unified storage of files, VM Images and live VM disks, independently of the backend storage technology  
  * Thin VM provisioning, with zero data copy and live VM migration
  * Current Industry and Open Source Community use cases of Synnefo
  * Production readiness/Scalability/Maintainability on commodity hardware
