3. Defining HA and DR High Availability (HA) Disaster Recovery (DR)
High availability is a system design protocol and associated implementation that ensures a certain absolute degree of operational continuity during a given measurement period.
Availability defined in terms of service level agreements (SLA)
Recovery Time
Data loss during unplanned downtime
Minimal planned downtime
Processes and procedures designed to restore business operations due to a natural or human-induced disaster
Typically involves providing redundancy spanning multiple sites or across geographic regions
Redundant HA
High light processes and pro
