The architecture presented in this document will set the standard for the target data centre services that will allow SSC to re-engineer, virtualize and consolidate DC services, and enable integration of various other partners and service providers. As the technologies and surrounding infrastructures evolve, the architecture will also need to evolve. The architecture is based on current concepts and technologies available within the data centre space. This approach will allow risk management groups to validate the compliance of each component's design and implementation with this document specification, thereby facilitating assessment efforts and accuracy. In addition, this document constitutes a key deliverable for achieving Security Assessment and Authorization (SA&A) and overall service authorization successfully. The security controls that are identified in this document are strongly influenced by Communications Security Establishment Canada's (CSEC's) Information Technology Security Guidelines (ITSG) publications. Partner organizations are responsible for implementing application-level security safeguards over and above those implemented by SSC in its data centres in order to meet their particular information security requirements. Secret) where required through appropriate safeguarding measures over and above those implemented for the PBMM baseline.
End-state data centres will also support workload profiles above PBMM (e.g. The target baseline security profile for SSC's end-state data centre services is Protected B, Medium Integrity, Medium Availability (PBMM). The logical and physical architecture required to meet the intent of the conceptual architecture described in this deliverable is the subject of associated Technical Architecture Documents (TADs). This document is limited to articulating the conceptual data centre infrastructure architecture. The architecture will support the delivery of DCCP services for SSC's partner organizations over the near term (less than three years), with an evolutionary capability to encompass a hybrid cloud service delivery model for long-term strategic planning. The DCS RAD defines the end-to-end architectural model and the components that will form the basis for developing the Shared Services Canada (SSC) target end-state DC services for the Data Centre Consolidation Program (DCCP).
The Data Centre Services (DCS) Reference Architecture Document (RAD) has been developed to describe the reference architecture models for a common, shared and consolidated DC environment for the Government of Canada (GC) as an enterprise.
