GC Service & Digital Target Enterprise Architecture (view source)

The next layer projects the idea of a service‑oriented government, with a user‑centred approach to the business of government that puts citizens and their needs as the primary focus of our work, using “tell‑us‑once” service approaches, integrated services across the GC program and service landscape in a way that provides real‑time information to Canadians about their service applications. It is a perspective centred on users and service delivery when considering new IT solutions or modernizing older solutions. It builds on business architecture guidance to design for users first, focusing on the needs of users, using agile, iterative, and user‑centred methods in a whole-of-government context.

Leveraging the concept of harmonization described for external users through Sign‑in Canada, GCPass will enable authentication and authorization to GC Systems for Internal stakeholders. The digital workplace will uniformly enable the work of public servants, building on a standard design.

Information architecture is depicted in the following layer. Information architecture best practices and principles aim to support the needs of a business service and business capability orientation. To facilitate effective sharing of data and information across government, information architectures should be designed to reflect a consistent approach to data, such as the adoption of federal and international standards. Information architecture should also reflect responsible data management, information management and governance practices, including the source, quality, interoperability, and associated legal and policy obligations related to the data assets.
Information architectures should also distinguish between personal and non‑personal data and information as the collection, use, sharing (disclosure), and management of personal information must respect the requirements of the ''Privacy Act'' and its related policies.

The following layer depicts how services will interoperate through a standard fabric, supported by a set of common API standards specifying protocols and payloads. These services will be published in the API Store to facilitate reuse. APIs will be brokered through an API gateway to manage traffic, ensure version control, and monitor how services are exposed and consumed, either directly, or through a common event broker. Procurement of software as a service (SaaS) offerings will be facilitated through Shared Services Canada’s (SSC’s) Cloud Brokering Service and supported through their managed services. These are services that are available to steward infrastructure that are offered by SSC include database management services, cabling, facility management, transition planning and support, system integration services, and project management, among others. GC business programs and services and their enabling capabilities are built on resources within the application and information landscapes.

Also highlighted in this layer are automation capabilities such as artificial intelligence and open source solutions listed on an open resource exchange. '''ADD Image''' Application architecture and technology architecture (duplicated?)
In the bottom‑most view of the Service and Digital Target Enterprise Architecture, the focus is on the technology infrastructure that acts as the glue to bring everything together: the network. The GC network consists of local area network (LAN), wide area network (WAN), satellite, and internet infrastructure that provides general connectivity for internal government users, as well as secure and networks that support collaboration between the government and scientific communities. These are all connected with network hubs that optimize the performance of the GC network. The core infrastructure includes SSC services that ensure IT continuity (disaster recovery), including performance monitoring and reliability planning.

Security is reflected in the Service and Digital Target Enterprise Architecture diagram as a cross‑cutting factor that spans all horizontal layers. The goal is to ensure security at all architectural levels, from design to implementation to operations; and to ensure authentication, authorization, auditing, monitoring, tokenization, and encryption of all data, whether at rest or in motion.
