Agile Infrastructure IaaS Compute Jan van Eldik CERN IT Department Status Update 6 July 2012

Outline IaaS Compute – What are we doing? OpenStack Nova – What do we use? Deployments – What does it look like? Demo!

IaaS Compute overview Aim: Deliver a production IaaS service through a series of time-based pre-production services of increasing functionality and Quality-of- Service… …to manage the infrastructure more efficiently Different use cases: – Server consolidation – Batch computing – Disaster recovery This is an integration effort – As opposed to a development effort – Landb, ActiveDirectory, DataCenter operations, …

Different Service Models Pets are given names like lsfmaster.cern.ch They are unique, lovingly hand raised and cared for When they get ill, you nurse them back to health Cattle are given numbers like vm0042.cern.ch They are almost identical to other cattle When they get ill, you get another one Future application architectures tend towards Cattle.. But users now need support for both modes of working

OpenStack Compute “Nova” Relevant components – Nova - Compute – Horizon - Dashboard – Keystone - Identity Management – Glance - Image management ~6 month release cycle – Essex - April 5, 2012 – Folsom - Sept 27, 2012 – “Grizzly” – April 2013

OpenStack RPMs RPMs produced by Fedora “Cloud SIG” – Very responsive community – Standard Fedora processes – RPMs for EPEL6, Fedora 16/17 Regular security and bug fix releases Minimal delay between OpenStack releases and RPM availability Note: RedHat joined the OpenStack Foundation in April, but they have not yet revealed any strategy

Configuration, Images, … Configure using Puppetlabs modules – Recently ported to Fedora and RHEL6 With CERN help – Released last week Images created with Oz – Part of (RedHat sponsored) project Aeolus – SLC6, SLC5 “server” images – Contextualization w/ cloud-init Interpreting user-specified data – WIP: Windows images Use GlusterFS – Provide block storage, VM live-migration

CERN deployments Guppy First pre-production, released June 1 st Target audience: AI project members OpenStack Essex on Fedora 16, KVM only Used for functionality tests – Live-migration, resize, … Limited integration in Cern infrastructure – single IP service, no Cern accounts School of guppies to be deployed as an AI testbed

CERN deployments Hamster Scheduled for Sept 1 st AI project members, early adopters OpenStack Essex on SLC6 Proper integration in Cern infrastructure – multiple IP services, user defined hostnames – Accounts and roles from Active Directory – Window images Demonstrate VM backup Deploy Hyper-V hypervisors

CERN deployments IaaS Compute v 1.0 Production release, scheduled Q OpenStack Folsom on SLC6 To be deployed in Meyrin and Budapest DCs – Batch worker nodes – Service nodes, selected pets (Meyrin only)
