Enterprise Architecture for LandWarNet 2020 and Beyond

The Army Information Enterprise Architecture (IEA) is a high-level representation of the LandWarNet (LWN) architecture, as it supports the Army’s Enterprise Information Environment, Warfighting, Business, and Defense Intelligence Mission Areas. The IEA is sub-divided into the LWN 2020 and Beyond Enterprise Architecture (EA), and a set of Enterprise Reference Architectures (RAs), all of which the Chief Information Officer (CIO)/G-6 develops.

The hierarchy of the IEA, and the context in which it fits, is shown below.


The overall objective of these documents is to provide the architecture guidance and direction for LWN to achieve the vision in the Army Network Campaign Plan (ANCP). This includes policy, principles and rules, constraints, technical guidance, standards and forecasts, implementation conventions, and criteria. Each of these documents has a unique role in the IEA by providing specific architecture-related information, as described below.

    • Annex A: Technical Standards Guidance v2.0 (Aug 2014). Describes the Army Technical Guidance Repository that provides the technical standards for LandWarNet IT systems. Provides Army-level guidance to the Acquisition and IT System Development communities. Establishes the Technical Standards Lifecycle Management process.
      • Appendix C to Annex A: Army Standards Profile Guidance In Support of Common Operating Environment (COE) v3. Describes a new process, leveraging the DoD Information Technology Standards Registry, to create the annual Army CIO/G-6 Standards Profile Guidance. Provides technical guidance to the acquisition/testing community for COE v3 implementation in FY19 and supports Program Objective Memorandum FY17-21 planning for Materiel Developers. Tab A (Core) provides Army IT system developers and stakeholders with an Army Standards Profile. Tab B (Use Cases) provides additional data supplements for TAB A and Use Cases for Big Data, Cloud Computing, and Content Delivery & Discovery.
  • Enterprise Reference Architectures. The reference architectures includes policy, principles and rules, constraints, technical guidance, standards and forecasts, implementation conventions, and criteria. At the level of detail needed to support the evaluation of potential Information Technology (IT) investments for their alignment with the ANCP.
    • Army Enterprise Cloud Computing v1.0 (Sept. 2014); v2.0 to be published in 2015. Informs, guides, and constrains delivery of cloud computing environments in DoD and non-DoD data centers and application migrations to these environments in support of the Army's transition to cloud computing.

    • Army Enterprise Service Management v1.0 (May 2015). Ensures the Army capability to deliver information technology enterprise services across the full range of military operations through the Army Enterprise Service Management Framework in alignment with the Defense Enterprise Service Management Framework. It complements and guides the Army’s existing service management practices and capabilities by providing principles, rules, technical positions and implementation patterns.
