The Alliance is composed of missions and enterprises with many data types. These include both structured and unstructured data, such as relational tables in databases, Extensible Markup Language (XML), spreadsheets, images, videos, audios, documents, and more. To advance Alliance data interoperability, a modernized data management architectural design is required—one that relies on a set of technical capabilities based on clear data standards and governance to enable secure Alliance-wide discovery and exploitation of shareable data. Leveraging the data mesh approach does not require wholesale disruption to legacy architectures. Data mesh has many advantages for enabling a decentralized architecture that, combined with Zero Trust Architecture (ZTA) and NATO's Digital Backbone, will allow Alliance elements to maintain secure control of their data while sharing without duplication.
