Oracle 12c Data Guard Architecture

Data Guard is basically a ship redo and then apply redo, as you know #redo is the information needed to recover a #database transaction. #Dataguard is meant for DISK OUTAGE (or) SITE OUTAGE. Data guard is a disaster Recovery solution.
A production database referred to as a primary database transmits redo to one or more independent replicas referred to as #standby databases.
Standby databases are in a continuous state of recovery, validating and applying redo to maintain #synchronization with the primary database. A standby database will also automatically re-synchronize if it becomes temporary disconnected to the primary due to power outages, network problems, etc.
