© 2008 Progress Software Corporation3 OPS-13: Building & Deploying a Highly Available Application Agenda  Highly Available Application (HAA) – what it means today & tomorrow  Definitions  Levels of Recovery

© 2008 Progress Software Corporation4 OPS-13: Building & Deploying a Highly Available Application 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)

© 2008 Progress Software Corporation8 OPS-13: Building & Deploying a Highly Available Application 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" ( percent)...” ReliabilityOK For Expected Outages/Year Three 9's99.9%Homes9 hours Four 9's99.99%Factories59 minutes Five 9's99.999%Hospitals5 minutes Six 9's %Banks32 seconds Seven 9's %Digital Markets30 msec (Source: (Source:

© 2008 Progress Software Corporation15 OPS-13: Building & Deploying a Highly Available Application Levels of Recovery Level 1: Bicycle Recovery Level 2: VW Recovery Level 3: Race Car Recovery

© 2008 Progress Software Corporation16 OPS-13: Building & Deploying a Highly Available Application 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:

© 2008 Progress Software Corporation17 OPS-13: Building & Deploying a Highly Available Application Level 1: Technology Dependence  NO RPO or RTO  Have never had an incident  Not using their existing resources  Don’t rely completely on technology!

© 2008 Progress Software Corporation18 OPS-13: Building & Deploying a Highly Available Application Level 1: Technology Choices  Backup Infrastructure –Hardware –Software Application –Configuration files –Properties files  Where is your recovery location?

© 2008 Progress Software Corporation19 OPS-13: Building & Deploying a Highly Available Application 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:

© 2008 Progress Software Corporation21 OPS-13: Building & Deploying a Highly Available Application Level 2: Technology Choices  After imaging  Replication or clusters  SAN solutions  Recovery offsite?

© 2008 Progress Software Corporation22 OPS-13: Building & Deploying a Highly Available Application 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:
