CORPORATE ARCHITECTURE & TECHNOLOGY SERVICES
Senior Architecture Expertise for Complex Technology Environments
DNC helps organisations understand, design, secure and modernise business-critical technology environments with senior architecture expertise focused on practical delivery.
From current-state discovery and HLD/LLD through to cloud, infrastructure, migration, security and resilience, we provide the technical clarity needed to make complex change manageable.
Current-State Discovery • HLD / LLD • Cloud & Infrastructure • Security • Migration • Resilience • Technical Leadership
ARCHITECTURE SERVICES
From discovery through to implementable design
DNC works across business-critical platforms, cloud, infrastructure, databases, security and operational services to create architecture that can actually be delivered and supported.
Current-State Discovery
Inventory, dependencies, data flows, network paths, security controls, operational ownership and architecture mapping.
High-Level Design
Target architecture, principles, service boundaries, integration, security, resilience and technology decisions.
Low-Level Design
Detailed configurations, network and security design, component specifications, implementation requirements and build guidance.
Migration & Modernisation
Roadmaps, sequencing, dependency analysis, cutover planning, rollback, testing and transition into the target environment.
Security & Resilience
Identity, access, segmentation, hardening, backup, recovery, HA/DR, monitoring and secure-by-design architecture.
Technical Leadership
Architecture assurance, design review, supplier challenge, decision support and senior technical input across delivery programmes.
CURRENT-STATE DISCOVERY
Understand what is really there before deciding what comes next
Documentation often falls behind the environment. DNC can reverse-engineer an existing platform to establish how systems are actually connected, secured and operated.
This creates an evidence-based baseline for transformation, cloud migration, supplier change, security review, resilience improvement or technical due diligence.
Typical discovery outputs
Infrastructure and cloud inventory
Application and service dependencies
Network and data-flow mapping
Identity and access review
Backup and resilience position
Operational ownership and support boundaries
Current-state architecture diagrams
Risks, gaps and target-state recommendations
HLD & LLD
Architecture documentation that supports delivery, not just governance
Good design documentation should help engineers build, operators support and stakeholders understand the environment. DNC develops architecture packs that connect business requirements to practical technical implementation.
We can document an existing environment, create a new target design, or bridge the two with a phased transition plan.
Design pack content can include
Architecture principles and requirements
Logical and physical diagrams
Network, connectivity and security design
Identity and access model
Compute, storage and platform design
Backup, HA and DR architecture
Monitoring and operational requirements
Implementation and migration considerations
Risks, assumptions and design decisions
TRANSFORMATION & MIGRATION SUPPORT
Connect strategy to the engineering work required to deliver it
DNC can support transformation programmes from early architecture through detailed design, migration planning, technical assurance and implementation support.
We work across OCI, AWS, Azure, hybrid infrastructure, Oracle platforms, networking, security and business-critical applications, helping identify cross-platform dependencies before they become delivery problems.
ENGAGEMENT MODELS
Senior expertise where you need it
Engage DNC for a focused review, a defined architecture deliverable or ongoing technical leadership within a larger programme.
Architecture Review
Independent review of an existing or proposed design, with risks and recommendations.
Current-State Assessment
Discovery, inventory, diagrams, dependencies and technical risk baseline.
HLD / LLD Delivery
Architecture and detailed design documentation for a defined platform or transformation.
Fractional Architect
Ongoing senior architecture support without the overhead of a large consultancy engagement.
HOW DNC WORKS
Discover → Assess → Design → Deliver → Secure → Optimise
We work from evidence, challenge assumptions and create designs grounded in the environment, constraints and business outcomes rather than a preferred vendor or predetermined solution.
