MISSION · SHARED FOUNDATION · OPERATIONS Design day two A landing zone provides a hosting foundation. The mission still needs clear service ownership, security interfaces, operating responsibilities and evidence of how the work will be sustained.
THE RELATIONSHIP
Hosting, shared services and mission ownership. HOSTING Provider & landing zone Uses / inherits Use the contracted cloud services and the landing-zone capabilities made available to this system. Retains The provider and platform owners remain responsible for their respective services and configurations. Evidence to confirm Which services and settings are in scope? Which responsibilities and evidence are actually available? SHARED SERVICES General Support System (GSS) Uses / inherits Use agreed shared services such as identity, network connectivity, logging and monitoring. Retains Shared-service owners manage their services, interfaces and operating handoffs. Mission-specific work remains explicit. Evidence to confirm What may the mission inherit? Are service scope, owners, dependencies and evidence documented? MISSION SYSTEM Mission & application team Uses / inherits Consume only the platform and shared services confirmed for the proposed mission boundary. Retains Own mission data, application configuration, service outcomes and responsibilities not provided by others. Evidence to confirm Which controls and dependencies remain mission-owned? What evidence and recovery testing are still needed? At every interface What crosses the boundary? Who owns the handoff? What evidence confirms it works?
Illustrative relationships, not automatic control inheritance. Confirm actual service scope, authorization boundaries and evidence for the engagement.
THE OPERATING MODEL
Make the handoff visible. Service and platform ownership Who owns the service, changes the shared environment and restores the platform?
Security and monitoring How do the platform team, cybersecurity service provider (CSSP) and mission team exchange telemetry, decisions and evidence?
Change and continuity How is a release approved? What continues during disconnection? Who proves recovery and reconciles the record?
SEE IT WORK
Follow an event. Change the connection. Connected, intermittent, disconnected Explore the relationship between local continuity and enterprise dependencies. Use it to frame the decisions a real environment must test.
