Synnefo is an open source cloud platform written from scratch in Python. It provides Compute, Network, Image, Volume, Object Storage, Identity, and Quota services, exposing the corresponding OpenStack APIs. To do so, Synnefo manages multiple Ganeti clusters in the backend, and uses Archipelago to unify cloud storage.
Synnefo has been used to power GRNET's large-scale "~okeanos" public cloud service, currently hosting over 9.000 VMs, with over 323.000 VMs launched in the last two years.
In this presentation, Vangelis Koukis will focus on why Synnefo chose to go the Google way, and why targeting enterprise-like, persistent VMs in a cloud stack matters. After presenting the general Synnefo architecture and components used (Python, Django, Ganeti, KVM, Archipelago, Ceph/RADOS), the talk will review how Synnefo provides a unified view of cloud storage resources over Archipelago.
