Looker (Google Cloud Core) 通过 Google Cloud 控制台提供简化且顺畅的 Looker 实例预配、配置和管理。您还可以通过控制台执行一些实例管理任务。
Looker (Google Cloud Core) 实例由 Google 托管在 Google Cloud中。Looker (Google Cloud Core)不适用于客户托管或多云环境。
Looker (Google Cloud Core) 版本
Looker (Google Cloud Core) 提供多个版本。每种版本类型提供的功能各不相同，价格也有所不同。创建 Looker (Google Cloud Core) 实例时，您可以选择满足您需求的版本。创建实例后，您无法更改版本类型。您还可以预配、配置和管理相同版本类型的非生产实例，以用于预演和测试。如需了解有关设置非生产实例的注意事项，请参阅本页面的预演环境和测试部分。
标准版
标准版专为小型团队以及内部平台用户人数不超过 50 人的中小型企业量身打造。除了许多现有的 Looker (Google Cloud Core)功能之外，标准版还带来了新功能，包括：
- Google Cloud Identity 访问权限管理和简化的 BigQuery 连接。
- 每月最多支持 1,000 次查询相关 Looker (Google Cloud Core) API 调用，以及每月最多 1,000 次管理相关 Looker (Google Cloud Core) API 调用。如需详细了解该 API，请参阅使用 Looker (Google Cloud Core) API 部分。
标准版可通过年度合同购买。

嵌入式版本可通过年度合同购买。
非生产实例
如果您想使用临时或测试实例，可以使用创建 Looker (Google Cloud Core) 实例的标准流程创建非生产环境实例，并选择合适的非生产环境版本。此非生产实例的结算方式将与任何其他 Looker (Google Cloud Core) 实例相同。如需了解详情，请参阅 Looker (Google Cloud 核心版) 价格页面。
非生产实例版本的类型与可用于生产实例的版本相同，包括以下版本：
每个非生产版本提供的功能与生产版本提供的功能相同。非生产 Looker (Google Cloud Core) 实例也可以具有与生产实例相同的网络连接类型。在所有环境中都具有相同的功能，可让您将预演环境配置为与生产环境相匹配，并在部署到生产实例之前测试更新。
非生产实例的特征
以下是有关非生产 Looker (Google Cloud Core) 实例的一些注意事项：
- 非生产实例不在任何 Google 服务等级协议 (SLA) 的涵盖范围内。
- 横向伸缩不属于非生产用例。如果您需要在多个 Looker (Google Cloud Core) 实例之间分散实例负载，并为生产使用场景提供特定的地理分布，则需要购买现有生产 Looker (Google Cloud Core) 版本的其他实例。
- 非生产 Looker (Google Cloud Core) 实例不能代替生产实例使用，也不能用于生产目的。
- 所有生产和非生产 Looker (Google Cloud Core) 实例都遵循相同的发布周期。您可以将非生产实例的维护设置配置为与生产实例的维护设置保持一致。
试用实例
如果您想试用 Looker (Google Cloud Core)，可以创建试用版标准版、企业版或嵌入版实例，这些实例将具有与相应正式版相同的功能支持。试用版存在以下限制：
- 试用版实例的有效期为 90 天。90 天后，您必须删除或升级实例。
- 无法直接升级到非试用版实例。如需升级，您需要创建一个新实例，然后从试用实例中导入数据。
- 对于 Google Cloud 项目和 Google Cloud 区域的每种组合，每种版本类型只能有一个有效试用。
- 试用版不包含 Looker Studio Pro 许可。
