Low cost cloud in BNCF

  1. 1. Open low cost HA cluster cloud Cristiano Corsani – system engineer - IT department - Florence National Library Giovanni Toraldo – OSS solutions architect at Libersoft Low cost cloud for BNCF EVA Florence 2012
  2. 2. BNCF services Cultural Heritage Ministry has progressively reduced the investment SBN - national cataloguing system OPAC - online public access catalogue WWW - our web interface Digital data access - public access to our digital storage Internal services - library management and Intranet servicesLow cost cloud for BNCF EVA Florence 2012
  3. 3. BNCF data center costs  Open Source – reduce costs of:  SOFTWARE: development and maintenance  LICENSING: server, apps and 250 workstation  Virtualization cloud – reduce costs of:  HARDWARE: maintenance and electricity costsLow cost cloud for BNCF EVA Florence 2012
  4. 4. VirtualizationLow cost cloud for BNCF EVA Florence 2012
  5. 5. Commercial solutions  Hypervisor license - depends on CPU and/or memory  Orchestrator license - live migration, HA, backup, …  Certified hardware – limited hardware supported  Centralized storage system – needed for HALow cost cloud for BNCF EVA Florence 2012
  6. 6. Our Open solution  Open hypervisor it comes with Linux kernel in standard distro  Orchestrator live migration, ha, backup, … intuitive and web based  Commodity hardware only very low requirements needed  No centralized storage system special network filesystem is used instead physical storageLow cost cloud for BNCF EVA Florence 2012
  7. 7. Compare3x Sun Fire (2 x quad-core Xeon, 24GB RAM, 2 x 500 GB SATA2) 3 HOSTS 6 CPU 72GB RAM 1TB Storage Commercial Our Open Hypervisor license 4000€ + 12000€/year --- Centralized storage 5000€ --- + FB lan Hardware 20000€ << 20000€ Installation + 500€/day 500€/day MaintenanceOur Open Cloud is: open, simple, easily scalable and affordableLow cost cloud for BNCF EVA Florence 2012
  8. 8. Open detailsGiovanni Toraldo, OSS solutions architect in LiberSoft  Virtualization (OpenNebula and Proxmox)  Massive long-term storage for digitalized resources (GlusterFS)  Migration to Open Source desktop/server platforms. (Ubuntu and MooseFS)Low cost cloud for BNCF EVA Florence 2012
  9. 9. Open hypervisor  Freely available: on your GNU/Linux distribution;  Enterprise-ready: powerful mix of enterprise features and a rich set of partners.  Support: widest range of hardware without hassles (Thanks Linux!)  High-performance: top-level virtualization benchmarks for Windows and Linux workloads.Low cost cloud for BNCF EVA Florence 2012
  10. 10. Open VM management software OpenNebula  Adaptable: highly modular.  Proven: massive scale production environments;  Interoperable: XML-RPC, EC2, OCCI Proxmox  Easy to deploy: ISO installer or from bare Debian  Easy to use: centralized web managementLow cost cloud for BNCF EVA Florence 2012
  11. 11. Low-end hardware requirements  The simplest virtualization host is... your laptop: CPU with virtualization extensions;  A bunch of available memory  A bunch of available disk space  Use your workstations to prepare VM before starting them in production.Low cost cloud for BNCF EVA Florence 2012
  12. 12. Focus on storage  Shared storage is not an option for live migration and High-Availability.  A good storage solution:  Availability: the sky should not fall on our heads;  Scalability: we add new bricks when needed;  Price.  Common choice is to use a dedicated NAS/SAN (NetApp, EMC, QNAP and so on).Low cost cloud for BNCF EVA Florence 2012
  13. 13. Our choice: GlusterFS  GlusterFS is an open source distributed network filesystem.  How it works?  Aggregate available disk space on your hosts;  Replicate data: HA and prevent data-loss;  Data available via LAN with standard protocols: FUSE, NFS, CIFS.Low cost cloud for BNCF EVA Florence 2012
  14. 14. GlusterFS advantages  Scalability: to Petabytes and beyond!  Affordability: use commodity hardware;  Flexibility: deploy in any environment;  Linear performances: no degradation;  HA: replicate data on multiple places;  Unified namespace: like a folder on a local diskLow cost cloud for BNCF EVA Florence 2012
