Properties

AccessDeniedException

403 response - You do not have sufficient access to perform this action.

Property	Type	Required	Description
`message`	string	True

AssertionRule

An assertion rule enforces that, when you change a routing control state, that the criteria that you set in the rule configuration is met. Otherwise, the change to the routing control is not accepted. For example, the criteria might be that at least one routing control state is On after the transaction so that traffic continues to flow to at least one cell for the application. This ensures that you avoid a fail-open scenario.

Property	Type	Required	Description
`AssertedControls`	Array of type string	True	The routing controls that are part of transactions that are evaluated to determine if a request to change a routing control state is allowed. For example, you might include three routing controls, one for each of three AWS Regions.
`ControlPanelArn`	string	True	The Amazon Resource Name (ARN) of the control panel.
`Name`	string Pattern: `^\S+$` MinLength: 1 MaxLength: 64	True	Name of the assertion rule. You can use any non-white space character in the name except the following: & > < ' (single quote) " (double quote) ; (semicolon)
`RuleConfig`	RuleConfig	True	The criteria that you set for specific assertion routing controls (AssertedControls) that designate how many routing control states must be `ON` as the result of a transaction. For example, if you have three assertion routing controls, you might specify `atleast` 2 for your rule configuration. This means that at least two assertion routing control states must be `ON`, so that at least two AWS Regions have traffic flowing to them.
`SafetyRuleArn`	string	True	The Amazon Resource Name (ARN) of the assertion rule.
`Status`	Status	True	The deployment status of an assertion rule. Status can be one of the following: PENDING, DEPLOYED, PENDING_DELETION.
`WaitPeriodMs`	integer Format: int32	True	An evaluation period, in milliseconds (ms), during which any request against the target routing controls will fail. This helps prevent "flapping" of state. The wait period is 5000 ms by default, but you can choose a custom value.

GatingRule

A gating rule verifies that a gating routing control or set of gating routing controls, evaluates as true, based on a rule configuration that you specify, which allows a set of routing control state changes to complete.

For example, if you specify one gating routing control and you set the Type in the rule configuration to OR, that indicates that you must set the gating routing control to On for the rule to evaluate as true; that is, for the gating control "switch" to be "On". When you do that, then you can update the routing control states for the target routing controls that you specify in the gating rule.

Property	Type	Required	Description
`ControlPanelArn`	string	True	The Amazon Resource Name (ARN) of the control panel.
`GatingControls`	Array of type string	True	An array of gating routing control Amazon Resource Names (ARNs). For a simple "on/off" switch, specify the ARN for one routing control. The gating routing controls are evaluated by the rule configuration that you specify to determine if the target routing control states can be changed.
`Name`	string Pattern: `^\S+$` MinLength: 1 MaxLength: 64	True	The name of the gating rule. You can use any non-white space character in the name except the following: & > < ' (single quote) " (double quote) ; (semicolon)
`RuleConfig`	RuleConfig	True	The criteria that you set for gating routing controls that designate how many of the routing control states must be `ON` to allow you to update target routing control states.
`SafetyRuleArn`	string	True	The Amazon Resource Name (ARN) of the gating rule.
`Status`	Status	True	The deployment status of a gating rule. Status can be one of the following: PENDING, DEPLOYED, PENDING_DELETION.
`TargetControls`	Array of type string	True	An array of target routing control Amazon Resource Names (ARNs) for which the states can only be updated if the rule configuration that you specify evaluates to true for the gating routing control. As a simple example, if you have a single gating control, it acts as an overall "on/off" switch for a set of target routing controls. You can use this to manually override automated failover, for example.
`WaitPeriodMs`	integer Format: int32	True	An evaluation period, in milliseconds (ms), during which any request against the target routing controls will fail. This helps prevent "flapping" of state. The wait period is 5000 ms by default, but you can choose a custom value.

InternalServerException

500 response - InternalServiceError. Temporary service error. Retry the request.

ResourceNotFoundException

404 response - MalformedQueryString. The query string contains a syntax error or resource not found.

Property	Type	Required	Description

Rule

A safety rule. A safety rule can be an assertion rule or a gating rule. To learn more, see <ulink type="documentation" url="r53recovery/latest/dg/routing-control.safety-rules.html">Safety rules</ulink> in the Amazon Route 53 Application Recovery Controller Developer Guide.

Property Type Required Description

Property	Type	Required	Description
`ASSERTION`	AssertionRule	False	An assertion rule enforces that, when a routing control state is changed, the criteria set by the rule configuration is met. Otherwise, the change to the routing control state is not accepted. For example, the criteria might be that at least one routing control state is `On` after the transaction so that traffic continues to flow to at least one cell for the application. This ensures that you avoid a fail-open scenario.
`GATING`	GatingRule	False	A gating rule verifies that a gating routing control or set of gating routing controls, evaluates as true, based on a rule configuration that you specify, which allows a set of routing control state changes to complete. For example, if you specify one gating routing control and you set the `Type` in the rule configuration to `OR`, that indicates that you must set the gating routing control to `On` for the rule to evaluate as true; that is, for the gating control "switch" to be "On". When you do that, then you can update the routing control states for the target routing controls that you specify in the gating rule.

ASSERTION

AssertionRule

False

An assertion rule enforces that, when a routing control state is changed, the criteria set by the rule configuration is met. Otherwise, the change to the routing control state is not accepted. For example, the criteria might be that at least one routing control state is On after the transaction so that traffic continues to flow to at least one cell for the application. This ensures that you avoid a fail-open scenario.

GATING

Property Type Required Description

Property	Type	Required	Description
`Inverted`	boolean	True	Logical negation of the rule. If the rule would usually evaluate true, it's evaluated as false, and vice versa.
`Threshold`	integer Format: int32	True	The value of N, when you specify an `ATLEAST` rule type. That is, `Threshold` is the number of controls that must be set when you specify an `ATLEAST` type.
`Type`	RuleType	True	A rule can be one of the following: `ATLEAST`, `AND`, or `OR`.

Inverted

boolean

True

Logical negation of the rule. If the rule would usually evaluate true, it's evaluated as false, and vice versa.

Threshold

integer

Format: int32

True

The value of N, when you specify an ATLEAST rule type. That is, Threshold is the number of controls that must be set when you specify an ATLEAST type.

Type

RuleType

True

A rule can be one of the following: ATLEAST, AND, or OR.

RuleType

An enumerated type that determines how the evaluated rules are processed. RuleType can be one of the following:

ATLEAST - At least N routing controls must be set. You specify N as the Threshold in the rule configuration.

AND - All routing controls must be set. This is a shortcut for "At least N," where N is the total number of controls in the rule.

OR - Any control must be set. This is a shortcut for "At least N," where N is 1.

ATLEAST
AND
OR

Status

The deployment status of a resource. Status can be one of the following:

PENDING: Amazon Route 53 Application Recovery Controller is creating the resource.

DEPLOYED: The resource is deployed and ready to use.

PENDING_DELETION: Amazon Route 53 Application Recovery Controller is deleting the resource.
