English英语译成Chinese汉语 市场开发 IT（信息技术） Cosmos DB

It’s worth noting that, as is now a tradition at Microsoft, Cosmos DB has long been used internally at Microsoft. {In its previous incarnation as DocumentDB}, Cosmos DB currently serves “tens of thousands of customers,” Microsoft says, and stores petabytes of data.

微软表示，｛在之前的版本（比如DocumentDB）中｝，Cosmos DB目前服务于“成千上万个客户”，存储数PB的数据。
前后衔接不上啊？！
注：Cosmos DB是微软推出的DocumentDB的升级版或改良版。
