Subsystem Objectives

Release 2 Objectives

(see also R2 CEI Construction Plan)

  • Get a definition of R2 adopter groups and understand their direct and indirect requirements of CEI (indirect requirements will be filtered by other subsystems, e.g. DM and SA)
  • Get a precise definition of the functional and non-functional requirements, and their priorities, that R2 adopter groups have on CEI; establish communication channels
  • Define a strategy for extending the R1 cloud management capabilities and a providing process management capabilities on top of them to satisfy those requirements; the strategy should integrate existing process management tools and, to a reasonable extent, position us for using National Infrastructure resources in the future
  • Integration with other subsystems; in particular DM (enabling the data management subsystem to achieve its goals) and COI (in particular on issues related to providing a robust system infrastructure for startup, continuous operations and failure compensation)
  • Support the SA (through DM) subsystem in the generation of real-time data products by applying developer defined algorithms to data streams
  • Identify and prepare functionality components for individual releases to ensure flexibility, adoption, impact and sustainability opportunities

Release 3 Objectives

See the [R3 CEI Construction Plan].


We produced an CI Technical Elements Overview for General Audiences, which may be useful to appreciate the overall context of this system.

Requirements Development

Architectural Background

The System Engineering section of this wiki contains the architectural materials for the CEI subsystem.
