Common Business Classification Requirements Need to categorize our business processes in terms of business impact. Tier I: Critical (production) Tier II Important (non-critical production) Tier III Necessary (non-essential)
Availability Continuum Tier I: Critical (production) Tier II: Important (non-critical production) Tier III: Necessary (non-essential) Unavailable Unavailable Available Highly Available Service Interruption! AAS Planning: Business Impact Analysis Analysis & Design: Rapid Recovery to Fault Avoidance Analysis & Design DR perspective – RTO/RPO

Appendix Tier definitions
Application Recovery Classification (Tier 1) • Tier 1 Critical aka Critical Production • Applications that are essential to the ability of the University to provide its services or perform its activities safely & effectively • Safety & Security: application is needed to support a safe and secure environment, physically and/or technologically • Learning, Education & Research: application is needed to carry out or directly support the academic mission of the University • Business Support Services: application allows the University to maintain necessary business operations, safeguard assets and ensure financial viability of the University • Public visibility outside of the University if high • Application generates revenue • May be co-dependent upon other tier 1 applications
Application Recovery Classification (Tier 2) • Tier 2 Important aka non-critical production • Applications that, while not critical, significantly support the ability of the University to provide its services or perform its activities. • Application is heavily used for day-to-day operations but is not “critical” • Application may be dependent on a tier 1 application • Application provides a service to a tier 1 application
Application Recovery Classification (Tier 3) • Tier 3 Non-essential • Applications that are nice to have but can wait for recovery of all critical and important applications • Application operates independent of other applications (no dependencies) • Application test or development environments
