  1. Allied Irish Bank’s Journey to an Oracle Private Cloud Kevin Callanan, Marie O’Driscoll Sept. 2013

  2. Presentation Objectives AIB Oracle Private Cloud Background HW & Stack Simplification Benefits Delivered Architecture and Features Status and Next Steps

  3. Legacy Environment Server platform (HP-UX PA-RISC) hosting large majority of AIB’s Oracle databases will reach end of life/support during 2013-2014 Current environment consists of: 80 independent Oracle databases supporting 95 business services 15 production servers running 5 different operating systems 25 Test/Dev servers running 5 different operating systems 6 versions of Oracle installed Complex multi-vendor stack Limited agility capabilities to react and respond to business requirements Legacy Estate HP PA-RISC 2*20 Cores 2*16 Cores HP Itanium 2*8 Cores HP Itanium 4*4 Cores HP PA-RISC 2*6 Cores IBM P-Series 2*2 Cores IBM Mainframe 3*IFL Complex legacy architecture presenting operational and cost challenges

  4. Hardware Standardisation New Estate Legacy Estate HP PA-RISC 2*20 Cores 2*16 Cores HP Itanium 2*8 Cores HP Itanium 4*4 Cores Oracle SPARC T4-4 6*16Cores HP PA-RISC 2*6 Cores IBM Mainframe 3*IFL IBM P-Series 2*2 Cores

  5. Stack Simplification & Rationalisation

  6. Database Consolidation 80 Production Databases to 8 (250 Test Databases to 25) (Multiple Tablespaces per Schema to 1 per Schema) New schema

  7. Simplified Management – OEM12c Node 4 Agent Node 5 Agent Node 6 Agent Node 1 Agent Node 2 Agent Node 3 Agent F5 - SLB OHS 1 OHS 2 OSM DB REPOSITORY SOLARIS 10 ZONE - OEM 12.1.0.2 Multi OMS

  8. Simplified Management – OEM12c • Monitoring and Alerting • Backup and Housekeeping jobs • Metering and Chargeback • Compliance Reporting • Configuration Management – My Oracle Support

  9. Oracle Private Cloud Benefits- Projected Significantly increase Service Availability Agile and Responsive to Business Requirements Reduced lead times and man effort for new database environment requests: Lead time 10 days -> 2 days Man effort 5 days -> 0.5 days Teams impacted 3 teams -> 1 team Significant Operational Efficiency Gains Current patching effort is 3 days per database 80 x 3 = 240 days Projected patching estimate is 10 days per database 8 x 10 = 80 days Saving 160 days Significantly Reduced Complexity Simplified environment via the reduction of supported configurations through rationalisation, standardisation and consolidation = operational gains

  10. Oracle Private Cloud Benefits - Realised Significantly increase Service Availability RAT & SPA - Replay issues and test Different Solutions Increased Tooling enabled identification of External Problem Agile and Responsive to Business Requirements 2013 - 15 New Environments 35 New Services Supporting New Agile Digital Banking Strategy One Team Delivering Freeing up multiple infrastructure teams to Add Value Elsewhere Significant Operational Efficiency Gains All Production Shell Database precreated Monitoring Enabled Backups Enabled Standby Enabled Patching – Solaris 11.1 and 11.2.0.4 Significantly Reduced Complexity

  11. Architecture & Features High Availability – Oracle 11g RAC, 3 nodes per DC Predictable Node Affinity – Oracle RAC Services Encapsulation Layer –Scan Listener and Service visible Data Guard Separation - Separate Listener & VLan One Service => 1 Tablespace (90%)

  12. Key Decisions/Considerations Keep it Simple Minimize Install Base Root Operating System – no Hypervisor Zones/LDoms not for DB Production Environments ASM – 2 ASM Disk Groups – DATA, FRA Resource Management CPU_COUNT - Partitioning 4 Resource Groups- Platinum, Gold, Silver, Bronze Tiering Design for Tiered Database Offering on 11G Easy Management of Outages Planned Unplanned
