The Enterprise Architecture Working Group (EAWG) helps cloud customers and providers develop industry-recommended, secure and interoperable identity, access and compliance management configurations and practices. The working group developed cloud reference architecture, the CSA Enterprise Architecture (formerly the TCI), overlays cloud platforms and solutions on existing common enterprise architectures hardened with security criteria and industry mappings from the CSA Cloud Controls Matrix. The EAWG will further develop additional reference models and education on categories of cloud solutions and related technologies for the secure configuration and adoption of emerging technologies in a vendor-neutral manner, inclusive of all CSA members and affiliates who wish to participate. This charter lays out the scope, responsibilities, and roadmap for the EAWG. We welcome all feedback and comments during this open review period.
