## Cloud Attributes
A cloud environment (e.g. GCP, Azure, AWS).
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
| `cloud.account.id` | string | The cloud account ID the resource is assigned to. | `111111111111`; `opentelemetry` |  |
| `cloud.availability_zone` | string | Cloud regions often have multiple, isolated locations known as zones to increase availability. Availability zone represents the zone where the resource is running. [1] | `us-east-1c` |  |
| `cloud.platform` | string | The cloud platform in use. [2] | `alibaba_cloud_ecs`; `alibaba_cloud_fc`; `alibaba_cloud_openshift` |  |
| `cloud.provider` | string | Name of the cloud provider. | `alibaba_cloud`; `aws`; `azure` |  |
| `cloud.region` | string | The geographical region within a cloud provider. When associated with a resource, this attribute specifies the region where the resource operates. When calling services or APIs deployed on a cloud, this attribute identifies the region where the called destination is deployed. [3] | `us-central1`; `us-east-1` |  |
| `cloud.resource_id` | string | Cloud provider-specific native identifier of the monitored cloud resource (e.g. an [ARN](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) on AWS, a [fully qualified resource ID](https://learn.microsoft.com/rest/api/resources/resources/get-by-id) on Azure, a [full resource name](https://google.aip.dev/122#full-resource-names) on GCP) [4] | `arn:aws:lambda:REGION:ACCOUNT_ID:function:my-function`; `//run.googleapis.com/projects/PROJECT_ID/locations/LOCATION_ID/services/SERVICE_ID`; `/subscriptions//resourceGroups//providers/Microsoft.Web/sites//functions/` |  |
**[1] `cloud.availability_zone`:** Availability zones are called "zones" on Alibaba Cloud and Google Cloud.
**[2] `cloud.platform`:** The prefix of the service SHOULD match the one specified in `cloud.provider`.
**[3] `cloud.region`:** Refer to your provider's docs to see the available regions, for example [Alibaba Cloud regions](https://www.alibabacloud.com/help/doc-detail/40654.htm), [AWS regions](https://aws.amazon.com/about-aws/global-infrastructure/regions_az/), [Azure regions](https://azure.microsoft.com/global-infrastructure/geographies/), [Google Cloud regions](https://cloud.google.com/about/locations), or [Tencent Cloud regions](https://www.tencentcloud.com/document/product/213/6091).
**[4] `cloud.resource_id`:** On some cloud providers, it may not be possible to determine the full ID at startup,
so it may be necessary to set `cloud.resource_id` as a span attribute instead.
The exact value to use for `cloud.resource_id` depends on the cloud provider.
The following well-known definitions MUST be used if you set this attribute and they apply:
- **AWS Lambda:** The function [ARN](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html).
Take care not to use the "invoked ARN" directly but replace any
[alias suffix](https://docs.aws.amazon.com/lambda/latest/dg/configuration-aliases.html)
with the resolved function version, as the same runtime instance may be invocable with
multiple different aliases.
- **GCP:** The [URI of the resource](https://cloud.google.com/iam/docs/full-resource-names)
- **Azure:** The [Fully Qualified Resource ID](https://learn.microsoft.com/rest/api/resources/resources/get-by-id) of the invoked function,
*not* the function app, having the form
`/subscriptions//resourceGroups//providers/Microsoft.Web/sites//functions/`.
This means that a span attribute MUST be used, as an Azure function app can host multiple functions that would usually share
a TracerProvider.
