Application architecture practices must evolve significantly for the successful implementation of the GC Enterprise Ecosystem Target Architecture. Transitioning from legacy systems based on monolithic architectures to architectures that oriented around business services and based on re‑useable components implementing business capabilities, is a major shift. Interoperability becomes a key element, and the number of stakeholders that must be considered increases.

Technology architecture is an important enabler of highly available and adaptable solutions that must be aligned with the chosen application architecture. Cloud adoption provides many potential advantages by mitigating the logistical constraints that often negatively impacted legacy solutions hosted “on premises.” However, the application architecture must be able to enable these advantages.

Technology architecture is defined as the management and organization of technical equipment and devices of a business. Technology architecture is an important enabler of highly available and adaptable solutions that must be aligned with the chosen application architecture. Cloud adoption provides many potential advantages by mitigating the logistical constraints that often negatively impacted legacy solutions hosted “on premises.” However, the application architecture must be able to enable these advantages. Therefore, objectives for cloud solutions must be implemented in a way that supports the application architecture.

The GC Enterprise Security Architecture program is a government‑wide initiative to provide a standardized approach to developing IT security architecture, ensuring that basic security blocks are implemented across the enterprise as the infrastructure is being renewed.
