Architecture Modernization
Modernize legacy systems into resilient, scalable, cloud-native platforms. Our architecture practice helps Canadian enterprises migrate to the cloud, adopt microservices, and implement DevOps practices that accelerate delivery while meeting stringent sovereignty and compliance requirements.
Legacy technology stacks constrain organizational agility, inflate operational costs, and create compounding security risk. Zaha Technologies' Architecture Modernization practice provides a structured, risk-managed path from outdated monoliths and on-premises infrastructure to cloud-native platforms that scale with your business. We bring over fifteen years of experience guiding Canadian enterprises through complex modernization programs, from initial assessment and target-state architecture through migration execution and post-migration optimization.
Our approach is pragmatic, not dogmatic. We evaluate every workload on its own merits and recommend the appropriate modernization pattern, whether that is a straightforward lift-and-shift to reduce hosting costs, a re-platform to leverage managed cloud services, or a full re-architecture into microservices for maximum flexibility. Every recommendation is grounded in total cost of ownership analysis, regulatory requirements, and your organization's capacity for change.
Security, compliance, and Canadian data residency are embedded into every architecture decision. Our certified cloud architects hold active credentials across AWS, Azure, and Google Cloud and have delivered modernization programs for some of Canada's most demanding regulated environments, including Tier 1 financial institutions, federal government departments, and critical infrastructure operators.
Key Capabilities
Cloud Migration Strategy
Assess workload readiness, define migration waves, and execute lift-and-shift, re-platform, or re-architect strategies that minimize risk and accelerate time to value.
Microservices Architecture
Decompose monolithic applications into loosely coupled, independently deployable services with well-defined domain boundaries and event-driven communication patterns.
API Gateway Design
Design and implement centralized API management layers with rate limiting, authentication, versioning, and developer portal capabilities for internal and partner ecosystems.
DevOps & CI/CD
Establish automated build, test, and deployment pipelines that enable multiple production releases per day with full traceability and rollback capabilities.
Infrastructure as Code
Codify entire infrastructure stacks using declarative templates, enabling reproducible environments, drift detection, and policy-as-code governance across all cloud providers.
Kubernetes & Container Orchestration
Deploy and manage production-grade container platforms with automated scaling, service mesh networking, observability, and multi-cluster federation for high-availability workloads.
The Canadian Context
Canadian data sovereignty requirements mandate that certain categories of personal, financial, and health data remain within Canadian borders. Zaha Technologies designs cloud architectures that leverage Canadian availability zones across AWS (Montreal, Calgary), Azure (Toronto, Quebec City), and GCP (Montreal) to satisfy federal and provincial residency obligations. Our architects are well-versed in the Digital Governance Standards Institute frameworks and align every modernization program with Treasury Board of Canada Secretariat cloud-adoption guidelines, ensuring that compliance is embedded from the architecture level rather than retrofitted after deployment.
Featured Case Study
Core Banking Platform Modernization for a National Bank
Challenge
A national Canadian bank was operating a 20-year-old monolithic core banking system that required 14-week release cycles, could not scale to handle peak transaction volumes, and posed increasing risk to OSFI regulatory compliance.
Result
Zaha led a phased modernization program that decomposed the monolith into 38 microservices running on Kubernetes across two Canadian Azure regions. Release frequency improved from quarterly to daily, transaction throughput increased by 260%, and the bank achieved full compliance with OSFI B-13 technology risk guidelines while reducing annual infrastructure costs by 31%.
