CDMI（Cloud Data Management Interface）接口標(biāo)準(zhǔn)1.0版由SNIA草擬，于2010年4月發(fā)布。對于云計算來說，CDMI提供了通用云計算管理基礎(chǔ)架構(gòu)，同時原本信息管理的重點已漸漸從儲存管理轉(zhuǎn)移圍繞在數(shù)據(jù)管理上。CDMI標(biāo)準(zhǔn)則可以協(xié)助用戶將特殊詮釋數(shù)據(jù)（Metadata）標(biāo)記在數(shù)據(jù)上，該詮釋數(shù)據(jù)會告訴端點儲存供貨商，什么樣的數(shù)據(jù)服務(wù)提供該數(shù)據(jù)（例如備份、歸檔、加密等）。

云計算基礎(chǔ)架構(gòu)管理可同時支持OCCI及CDMI兩種標(biāo)準(zhǔn)接口。為了達成協(xié)同運作，CDMI內(nèi)含可導(dǎo)出OCCI接口所獲得的信息，OCCI則提供被導(dǎo)出CDMI容器相對應(yīng)的儲存。

OCCI及CDMI可說是專門讓云計算及云儲存達成協(xié)同運作的標(biāo)準(zhǔn)化作業(yè)。該標(biāo)準(zhǔn)是通過OGF與SNIA兩者間的策略聯(lián)盟，以及通過跨SDO云標(biāo)準(zhǔn)協(xié)同小組之協(xié)調(diào)一致才達成。OCCI可充份利用CDMI已配置好，以及設(shè)定完成的儲存。一旦兩個接口采用相同原理及技術(shù)，單一用戶將能同時管理應(yīng)用程序的計算與儲存需求，并且符合配置在兩接口上需求的同時擴展。

1.0版CDMI接口標(biāo)準(zhǔn)主要內(nèi)容如下：CDMI 1.0 (April 12, 2010) SNIA Technical Position iii
