What standard for data center?

I would like to know which ISO standards should be apply for Data centers. Because my enterprise already started running public datacenter and trying to apply ISO standards as a benefit over competitors. Please kindly suggest me for which ISO we should choose and thanks you very much for your great courses about ISO. 
 

Answer:

One of the ISO standards more focused on data centers is ISO 20000, because it is related to the management of IT services. So, maybe can be interesting for you our blog about ISO 20000 https://advisera.com/20000academy/blog/ and also this page “What is ISO 20000?

Another standard related to data centers is the ANSI/TIA-942 although it is not ISO (is an American National Standard).
Anyway, if you want to focus more on security issues, then ISO 27001 might also be appropriate for a data center. So this article can be also interesting for you "What is ISO 27001?" : https://advisera.com/27001academy/what-is-iso-27001/
