  1. Agile InfrastructureIaaS Compute Jan van Eldik CERN IT Department Status Update 6 July 2012

  2. Outline • IaaSCompute • What are we doing? • OpenStack Nova • What do we use? • Deployments • What does it look like? • Demo!

  3. IaaS Compute overview • Aim: Deliver a production IaaSservice through a series of time-based pre-production services of increasing functionality and Quality-of-Service… • …to manage theinfrastructuremore 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, …

  4. 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

  5. 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

  6. Openstack @ CERN HORIZON KEYSTONE GLANCE NOVA Scheduler Compute Registry Image Volume Network

  7. 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

  8. 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

  9. CERN deployments Guppy • First pre-production, released June 1st • 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

  10. CERN deployments Hamster • Scheduled for Sept 1st • 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

  11. CERN deployments IaaS Compute v 1.0 • Production release, scheduled Q1 2013 • OpenStack Folsom on SLC6 • To be deployed in Meyrin and Budapest DCs • Batch worker nodes • Service nodes, selected pets (Meyrin only)
