Shared Infrastructure Environment

The remaining three priorities – Computing Infrastructure Readiness (CIR), Communications Readiness (CR) and NetOps Agility (NOA) – depict DoD’s shared infrastructure environment. Collectively, they represent the hardware layers of the GIG along with management and operational facilities that enable the Department to dynamically allocate, deploy or redirect infrastructure resources anywhere, anytime, in any operational environment. This may mean dynamically scaling resources allocated to critical applications and services or staging certain information forward to mitigate issues of intermittency in the tactical environment. It could mean rapidly deploying entire networks with a full range of capabilities to support a new theater of operations or recover from a natural or man-made disaster. These challenges require a robust infrastructure, one that is modular, scalable and can securely operate across a wide variety of environments.

Principles and Business Rules

The following core principles and business rules were identified as relevant and applicable to the three priorities representing the GIG’s entire common infrastructure environment (CIR, CR, NOA):

Shared Infrastructure Environment Principles

  • GIG infrastructure capabilities must be survivable, resilient, redundant, and reliable to enable continuity of operations and disaster recovery in the presence of attack, failure, accident, and natural or man-made disaster.
  • The GIG shall enable connectivity to all authorized users.
  • GIG infrastructure must be scalable, changeable, deployable and manageable rapidly while anticipating the effects of the unexpected user.

Shared Infrastructure Environment Business Rules

  • GIG infrastructure resources shall be discoverable, and available to both meet the dynamic demand of all mission requirements and support the monitoring and management of the GIG.
  • GIG infrastructure capabilities shall be designed, acquired, deployed, operated and managed in a manner which enables continuity of operations and disaster recovery in the presence of attacks, failures, accidents, and natural or man-made disaster to support customer SLAs.
