## Appendix HH Subpart - Cloud Computing

Reporting: The Army must collect, consolidate, and report commercial cloud spending as directed in the HQDA EXORD 009-20, 'Army Data Plan Implementation in Support of Cloud Migration', and subsequent fragmentary orders.

Implementation: To achieve this objective, the Enterprise Cloud Management Agency (ECMA) implemented the Technology Business Management (TBM) taxonomy with associated General Services Administration Product Service Codes (PSCs) and Contract Line-Item Numbers (CLINs) to provide more accurate and comprehensive reporting of cloud investments.

TBM Taxonomy

(1) Identify the cloud activity (e.g., migrating to the cloud, new software development in the cloud, etc.)

(2) Based on the cloud activity, use the assigned TBM tower and PSC to enable clear mapping of the requirement to an appropriate CLIN

(3) The cloud activity shall be used as the CLIN name
