The GRNET Cloud View and Strategy Panos Louridas Greek Research and Technology Network

The Context GRNET has been providing network connectivity to the Greek university and research centres for more than 10 years. It has also been providing computation resources via Grid computing Next step: Provide computing and storage resources as a Cloud Computing provider 19/03/2014The GRNET Cloud View and Strategy2

Goals Production-quality IaaS cloud similar to Amazon AWS Scalability to thousands users/nodes/VMs Persistent VMs Commodity components (no exotic network infrastructure) Everyone can use it: Super simple web UI No vendor lock-in Low admin costs, manageable by a small team 19/03/2014The GRNET Cloud View and Strategy3

The Result Production quality IaaS cloud, providing both computing and storage Everything open source: 19/03/2014The GRNET Cloud View and Strategy4 Ganeti by

Current Status Users: > 6000 VMs: More than 8000 currently active More than 280,000 VMs spawned so far More than 77,000 vLANS launched so far Typical VM flavour (more than 340 flavours available): – 4 cores (vCPUs), 80 Gbytes HD, 4 or 8 Gbytes RAM 19/03/2014The GRNET Cloud View and Strategy5

The setup 234 VMCs in the datacenter (5616 cores, ~1,1PB local raw storage) Organized in clusters of 13 nodes (rack boundary) Allocated for okeanos are 182 VMCs (4368 cores, ~870TB local raw storage) Total 41 SCs in the datacenter (~1,3PB raw storage) Two per rack Allocated for okeanos are 17 SCs (~544TB raw storage) Organized in one ceph cluster VMC = Virtual Machine Container (24 total cores, 4,8TB local raw storage) SC = 12 total cores, 600GB SSD, 7.2TB SAS, 24TB SATA storage 19/03/2014The GRNET Cloud View and Strategy6

See it live 19/03/2014The GRNET Cloud View and Strategy8

Next Steps Move beyond IaaS to SaaS offerings Develop and offer big data processing products (i.e., super user-friendly Hadoop on demand) Increase HW infrastructure 19/03/2014The GRNET Cloud View and Strategy9

To Build or To Buy? Question posed back in 2010 Buying licenses of proprietary software not an option Leasing resources on public cloud providers not an option Available open source solutions back then not at the required level 19/03/2014The GRNET Cloud View and Strategy10

Build: The Good Parts Gain know-how Customize services to specific user needs A NREN can become a software house Requires robust engineering principles and quality control Cheaper than proprietary solutions Can create ecosystem of people building on top of your product You cannot compete with Amazon et al. on features, but you can compete on openness 19/03/2014The GRNET Cloud View and Strategy11

Build: The Bad Parts Takes time (buying or leasing resources takes only a credit card) Users may perceive you as an infinite resource, or feel entitled to your resources Requires robust engineering principles and quality control Supporting an ecosystem of people around your product requires extra effort 19/03/2014The GRNET Cloud View and Strategy12
