Specifying the URN for an endpoint

When you create an endpoint, you must specify a Unique Resource Name (URN). You will use the URN to reference the endpoint when you create configuration XML for the platform service. The URN for each endpoint must be unique.

StorageGRID validates endpoints as you create them. Before you create an endpoint, confirm that the resource specified in the endpoint exists and that it can be reached.

URN elements

The URN for an endpoint must start with either arn:aws or urn:mysite, as follows:

If the service is hosted on AWS, use arn:aws.
If the service is hosted locally, use urn:mysite

For example, if you are specifying the URN for a CloudMirror endpoint hosted on StorageGRID, the URN might begin with urn:sgws.

The next element of the URN specifies the type of platform service, as follows:

Service	Type
CloudMirror replication	`s3`
Notifications	`sns`
Search integration	`es`

For example, to continue specifying the URN for a CloudMirror endpoint hosted on StorageGRID, you would add s3 to get urn:sgws:s3.

The final element of the URN identifies the specific target resource at the destination URI.

Service	Specific resource
CloudMirror replication	`bucket-name`
Notifications	`sns-topic-name`
Search integration	`domain-name`/`index-name`/`type-name` Note: You must create the Elasticsearch index before you create the endpoint. Endpoint validation is done using the Elasticsearch index. The type will be dynamically created when object metadata is first sent to the destination.

URNs for services hosted on AWS

For AWS entities, the complete URN is a valid AWS ARN. For example:

CloudMirror replication:
```
arn:aws:s3:::bucket-name
```

Notifications:

arn:aws:sns:region:account-id:topic-name

Search integration:
```
arn:aws:es:region:account-id:domain/domain-name/index-name/type-name
```
Note: For an AWS search integration endpoint, the domain-name must include the literal string domain/, as shown here.

URNs for locally-hosted services

For locally-hosted services, you can specify the URN in any way that creates a valid and unique URN, as long as the URN includes the required elements in the third and final positions. You can leave the elements indicated by optional blank, or you can specify them in any way that helps you identify the resource and make the URN unique. For example:

CloudMirror replication:
```
urn:mysite:s3:optional:optional:bucket-name
```
For a CloudMirror endpoint hosted on StorageGRID, you can specify a valid URN that begins with urn:sgws:
```
urn:sgws:s3:optional:optional:bucket-name
```

Notifications:

urn:mysite:sns:optional:optional:sns-topic-name

Search integration:
```
urn:mysite:es:optional:optional:domain-name/index-name/type-name
```
Note: For locally-hosted search integration endpoints, the domain-name element can be any string as long as the URN of the endpoint is unique.
