EVA Florence 2012 ~ Open low-cost HA cluster cloud

EVA Florence 2012 ~ Open low-cost HA cluster cloud

In the last few years, one of the main problems of the cultural heritage institution is the progressive reduction of the investments. The hardware maintenance and licensing costs greatly affects IT budget. Virtualization addresses the need to streamline and consolidate infrastructure, even if the license costs remain high for commercial clouds. Open source solutions allow you to implement virtualization cloud which performance and functionality are suitable for the masses, without the constraints of hardware certifications and proibitive licenses costs.

Our infrastructure allowed us to build a ha virtualized environment using commodity hardware, regardless of specific products or manufacturers. Based on the interaction between a common linux kernel module and a software-based storage pool, is managed by an intuitive web interface. The system provides adequate performances provisioning services like web pages, OPAC, digital resources showcase, cataloging tools, library management, mail, etc.

    Low cost cloud for BNCF EVA Florence 2012 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 management
  10. 11.

    Low cost cloud for BNCF EVA Florence 2012 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.
  11. 12.

    Low cost cloud for BNCF EVA Florence 2012 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).
  12. 13.

    Low cost cloud for BNCF EVA Florence 2012 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.
  13. 14.

    Low cost cloud for BNCF EVA Florence 2012 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 disk
