Please indicate in this section level of availability and risk you need to cover regarding this application based on following definitions :
Recovery Time Objective (RTO) is the duration of time and a service level within which a business process must be restored after a disaster (or disruption) in order to avoid unacceptable consequences associated with a break in business continuity. Note: RTO can’t be lower than achievable Recovery Time Actuals (RTA) because of the technological constraint.
Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time. Note: RTO can’t be lower than achievable Recovery Point Actuals (RPA) because of the technological constraint.
Definitions:
1-Tier = all services described below (front, middle and database) run under same OS (no matter if it is an OS on a pServer or a GuestOS in a vServer)
