高可用，脱胎于历经阿里巴巴 10 年生产验证的内部产品，支持具有数百万服务的大 规模场景，具备企业级 SLA 的开源产品。 实时：数据变更毫秒级推送生效；1w 级，SLA 承诺 1w 实例上下线 1s，99.9% 推送完成；10w 级，SLA 承诺 1w 实例上下线 3s，99.9% 推送完成；100w 级别，SLA 承诺 1w 实例上下线 9s 99.9% 推送完成。 规模：十万级服务/配置，百万级连接，具备强大扩展性。 CMDB：解决元数据存储，与三方 CMDB 系统对接问题，解决应用，人，资源关系。  Metrics：暴露标准 Metrics 数据，方便与三方监控系统打通。  Trace：暴露标准 Trace，方便与 SLA 系统打通，日志白平化，推送轨迹等能力，并且可以和计 量计费系统打通。  接入管理：相当于阿里云开通服务，分配身份、容量、权限过程。  用户管理：解决用户管理，登录，SSO 等问题。  nacos 客户端，每个客户端从 服务池中随机选择 5 个服务进行注册，随后随机订阅 5 个服务池中的服务；共 10w 个客户端，10w 个服务，50w 服务实例，观察注册过程中的服务端性能指标及推送 SLA。 注册完成后放置，达到稳定状态后再观察服务端性能指标，整个过程持续 20min。 之后所有施压机关闭，观察集群注销的服务端性能指标。 2. 大规模服务注册达到稳定状态后，部分实例频繁发布 场景描述
