Class SinglePointOfFailureRule

java.lang.Object

com.eqixiac.equinix.design.estate.rules.SinglePointOfFailureRule

All Implemented Interfaces:

EstateRule

public final class SinglePointOfFailureRule
extends Object
implements EstateRule

FindingCategory.SINGLE_POINT_OF_FAILURE.

• Missing secondary: a live cloud (SP) connection alone in its redundancy group (impact: the price of adding a secondary of the same type and bandwidth, a negative saving).
• Shared attachment: a redundancy group whose members all use one port, one Cloud Router or one Network Edge device (HIGH), or ports on one Equinix switch (MEDIUM).
• One path to a cloud: two or more live connections to one service profile that all leave from one port/router/device (HIGH) or from one metro (LOW).
• Single device: a provisioned Network Edge device with no redundant peer.

A secondary that exists outside the analysed scope cannot be seen; findings say so.
