# Environment

Environments define the different domains your Functions and Assets are available under. You can have one environment, or you can have many, e.g., a dev, stage, and prod. You can deploy a [Build](/docs/serverless/api/resource/build) to any of your Environments.

## Environment Properties

```json
{"type":"object","refName":"serverless.v1.service.environment","modelName":"serverless_v1_service_environment","properties":{"sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^ZE[0-9a-fA-F]{32}$","nullable":true,"description":"The unique string that we created to identify the Environment resource."},"account_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$","nullable":true,"description":"The SID of the [Account](/docs/iam/api/account) that created the Environment resource."},"service_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^ZS[0-9a-fA-F]{32}$","nullable":true,"description":"The SID of the Service that the Environment resource is associated with."},"build_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^ZB[0-9a-fA-F]{32}$","nullable":true,"description":"The SID of the build deployed in the environment."},"unique_name":{"type":"string","nullable":true,"description":"A user-defined string that uniquely identifies the Environment resource.","x-twilio":{"pii":{"handling":"standard","deleteSla":7}}},"domain_suffix":{"type":"string","nullable":true,"description":"A URL-friendly name that represents the environment and forms part of the domain name.","x-twilio":{"pii":{"handling":"standard","deleteSla":7}}},"domain_name":{"type":"string","nullable":true,"description":"The domain name for all Functions and Assets deployed in the Environment, using the Service unique name, a randomly-generated Service suffix, and an optional Environment domain suffix.","x-twilio":{"pii":{"handling":"standard","deleteSla":7}}},"date_created":{"type":"string","format":"date-time","nullable":true,"description":"The date and time in GMT when the Environment resource was created specified in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format."},"date_updated":{"type":"string","format":"date-time","nullable":true,"description":"The date and time in GMT when the Environment resource was last updated specified in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format."},"url":{"type":"string","format":"uri","nullable":true,"description":"The absolute URL of the Environment resource."},"links":{"type":"object","format":"uri-map","nullable":true,"description":"The URLs of the Environment resource's nested resources."}}}
