  1. OPS-13: Building and Deploying a Highly Available Application Brian Bowman Sr. Solution Engineer

  2. What part is the most important? OPS-13: Building & Deploying a Highly Available Application

  3. Agenda • Highly Available Application (HAA) – what it means today & tomorrow • Definitions • Levels of Recovery OPS-13: Building & Deploying a Highly Available Application

  4. HAA – What is it? • Ensuring the complete application is 100% available during the required business time • Meeting Business Needs • Recovery Time Objective (RTO) • Recovery Point Objective (RPO) • Eliminating all Single Point of Failures (SPF) • Including as many TLA’s as possible in one presentation… (TLA = Three Letter Acronyms) OPS-13: Building & Deploying a Highly Available Application

  5. Where does a Highly Available Application start? • Development • Deployment • Management Development Deployment Management Application development & deployment timeline OPS-13: Building & Deploying a Highly Available Application

  6. Where does a Highly Available Application start? Development Deployment Management Application development & deployment timeline OPS-13: Building & Deploying a Highly Available Application

  7. What does a HAA look like to the user? • The application is always available* • Performance is always acceptable • Data is NEVER lost • New functionality is timely OPS-13: Building & Deploying a Highly Available Application

  8. Definitions: High Availability (HA) “… high availability refers to a system or component that is continuously operational for a desirably long length of time. Availability can be measured relative to "100% operational" or "never failing." A widely-held but difficult-to-achieve standard of availability for a system or product is known as "five 9s" (99.999 percent) ...” (Source: http://searchdatacenter.techtarget.com/sDefinition/0,,sid80_gci761219,00.html#) (Source: http://www.cps-corp.net/9s.htm) OPS-13: Building & Deploying a Highly Available Application

  9. Agenda • Highly Available Application ( HAA) – what it means today & tomorrow • Definitions • Levels of Recovery OPS-13: Building & Deploying a Highly Available Application

  10. Business Services Data Sources Definitions: Complete Application • User Interface • Middleware (Application Server / Sonic™) • Data (database) • Common Infrastructure Enterprise Services Presentation Common Infrastructure Data Access OPS-13: Building & Deploying a Highly Available Application

  14. Agenda • Highly Available Application ( HAA) – what it means today & tomorrow • Definitions • Levels of Recovery OPS-13: Building & Deploying a Highly Available Application

  15. Levels of Recovery Level 1: Bicycle Recovery Level 2: VW Recovery Level 3: Race Car Recovery OPS-13: Building & Deploying a Highly Available Application

  16. Level 1: Business Case • Easiest environment to work in • RTO and RPO < 1 day • Typically • Host-based • Client-Server • Development left to the Application Partner (usually) Cost Scale: OPS-13: Building & Deploying a Highly Available Application

  17. Level 1: Technology Dependence • NO RPO or RTO • Have never had an incident • Not using their existing resources • Don’t rely completely on technology! OPS-13: Building & Deploying a Highly Available Application

  18. Level 1: Technology Choices • Backup • Infrastructure • Hardware • Software • Application • Configuration files • Properties files • Where is your recovery location? OPS-13: Building & Deploying a Highly Available Application

  19. Level 2: Business case • RTO and RPO < 60 minutes • Typically • Host-based • Client-server • N-tier • Development shared between AP and User • Deployment shared as well Cost Scale: OPS-13: Building & Deploying a Highly Available Application

  20. Level 2: Choosing The Right Tool Which tool would you choose… OPS-13: Building & Deploying a Highly Available Application

  21. Level 2: Technology Choices • After imaging • Replication or clusters • SAN solutions • Recovery offsite? OPS-13: Building & Deploying a Highly Available Application

  22. Level 3: Business Case • RTO and RPO < 5 minutes • Typically • All Deployment Models (Host-based, Client-server, N-tier, SaaS) • Real-time and near real-time • Large development organization • Deployment important (and difficult) Cost Scale: OPS-13: Building & Deploying a Highly Available Application

  23. Level 3: Thinking Ahead Of The Game • Rick Mears • 4 Time Indianapolis 500 winner • 6 Times – Poll position • 11 Times – Front row OPS-13: Building & Deploying a Highly Available Application

  24. Level 3: Technology Choices • Replication • Clusters • SAN solution with complete redundancy • Sonic ESB / CAA OPS-13: Building & Deploying a Highly Available Application
