|ENV||Data Centre - DMZ||Version:||1.0|
This Environment exists in the following Working Area(s):
The Data Centre - Demilitarized Zone (DMZ) Environment comprises facilities for communication between (both internal and external) end users/other party's systems on one hand and applications in the Back End Environment on the other hand. In the Data Centre - DMZ Environment, physical conditions (like power supply, cooling, fire prevention and physical security) meet very high standards.
This environment is complemented by/adjacent to the Data Centre - Back-end environment.
In the Data Centre - DMZ Environment, facilities are in place to support and secure transactions between internal and external end users or other party's systems and core business processes of ArchiSurance. Examples are orders that are placed on the ArchiSurance website and payment transactions with credit card services.
The quality demands of this Environment are:
|QA Group||Quality Attribute||Value||Rationale|
|Flexibility||Adaptability||HSC||ArchiSurance should be able to adapt facilities very quickly to respond to changing customer demands.|
|Reliability||Availability||High||Communications with the outside world are even more important than internal processing. Failure of facilities in this Environment will obstruct customer interaction and therefore lead to negative customer experience and damage to the brand.|
|Integrity||Medium||Because facilities in this Environment are used for interaction with external systems and users, sufficient provisions should be taken to safeguard the integrity of these facilities. Because facilities are placed in a safe (physical) location, in most cases the "Medium" level will be adequate.|
NB: Only the two or three most important Quality demands for this environments are rated here. The purpose of this listing is to generally characterize an Environment in terms of Quality demands.
