HOW DNC WORKS
From unclear current state to an actionable technical plan
DNC is often engaged where an organisation needs to understand an existing environment, reduce technical risk, prepare for migration or modernisation, or validate security before making the next investment decision.
The following anonymised examples illustrate the types of engagements DNC can support. They are presented without fabricated statistics, client identities or claims.
CASE STUDY 01
OCI Current-State Discovery & Architecture Recovery
Environment
Oracle workloads running across OCI with limited consolidated documentation and multiple infrastructure, security and resilience dependencies.
Challenge
Before future design decisions could be made, the organisation needed a reliable understanding of what was actually deployed, how components were connected, where responsibilities sat and what evidence existed for backup, disaster recovery, security and operational ownership.
DNC Approach
Reverse-engineer the estate from the tenancy outward, combining OCI inventory, network topology, IAM and policy review, compute and storage discovery, database and application-tier evidence, backup and resilience checks, security services, logging and automation review.
Delivery
Structured infrastructure inventory, network and connectivity mapping, current-state diagrams, dependency identification, security and access observations, backup/DR evidence, ownership gaps and the technical inputs required for HLD and LLD documentation.
Outcome
A documented current-state baseline that gives stakeholders a clearer foundation for risk review, target-state design, migration planning and future architecture decisions.
Challenge
A business-critical Oracle Database and E-Business Suite estate had accumulated technical debt, legacy dependencies and operational risk. The organisation needed to understand whether to stabilise, upgrade, migrate, modernise or combine those approaches.
DNC Approach
Assess the application and database tiers, integrations, operating system and platform dependencies, backup and recovery, security, identity, resilience requirements and supportability. Map the practical options against business constraints and change tolerance.
Delivery
Current-state assessment, dependency map, upgrade and migration considerations, target architecture options, cutover and rollback considerations, resilience requirements, security controls and a phased roadmap for legacy support and modernisation.
Outcome
A clearer decision path that allows the organisation to maintain essential legacy services while preparing for a controlled upgrade, OCI migration, hybrid design or broader modernisation programme.
CASE STUDY 02
Oracle & E-Business Suite Modernisation
Environment
Legacy Oracle Database and EBS workloads requiring continued support while future upgrade or migration options were assessed.
CASE STUDY 03
Cloud Platform & Landing-Zone Architecture
Environment
Cloud adoption spanning OCI, AWS, Azure or hybrid infrastructure, with a need for stronger architectural consistency and governance.
Challenge
Cloud growth had created questions around account or tenancy structure, networking, identity, security, automation, resilience, migration sequencing and operational ownership.
DNC Approach
Review the current platform and business requirements, define architectural principles, design or refine landing-zone foundations, establish network and identity boundaries, incorporate security and observability, and identify where Infrastructure as Code can improve repeatability.
Delivery
Current and target architecture, landing-zone design, network and identity model, security and governance controls, migration patterns, resilience considerations, Infrastructure as Code approach and implementation roadmap.
Outcome
A more deliberate cloud foundation that can support migration, modernisation and future growth without treating governance, resilience or security as later additions.
Challenge
The organisation needed to understand exploitable weaknesses and configuration risks across its external attack surface, infrastructure, cloud services, web applications or access-control model before attackers could take advantage of them.
DNC Approach
Agree an authorised scope, identify the relevant attack surface, perform vulnerability and configuration assessment, validate findings, distinguish technical noise from meaningful risk and review weaknesses in the context of the underlying infrastructure and cloud architecture.
Delivery
Executive summary, technical findings, severity and prioritisation, supporting evidence, remediation guidance, hardening recommendations and, where required, retesting to confirm corrective action.
Outcome
A prioritised view of security risk that helps technical teams focus remediation effort on weaknesses that matter rather than relying solely on automated scanner output.
CASE STUDY 04
Cyber Security & Vulnerability Assessment
Environment
Authorised assessment of infrastructure, cloud, web, configuration and access-control risks.
CASE STUDY 05
Corporate Architecture & Transformation Planning
Environment
Mixed legacy, cloud and business-critical platforms with multiple dependencies and competing transformation priorities.
Challenge
The organisation needed a coherent technical view across infrastructure, cloud, applications, data, security and operational ownership before committing to a wider transformation programme.
DNC Approach
Review the current estate, identify architectural dependencies and constraints, assess resilience and security considerations, clarify target-state principles and map realistic transition options against business priorities.
Delivery
Current-state architecture, dependency and risk analysis, target-state options, migration sequencing, HLD and LLD inputs, security and resilience considerations, decision points and a phased transformation roadmap.
Outcome
A clearer architecture and delivery path that helps stakeholders make investment and sequencing decisions with a stronger understanding of technical risk and dependency.
Challenge
A growing business had technology spread across websites, hosting, domains, DNS, email, cloud services, backup and security with limited internal technical resource and no single view of risk or ownership.
DNC Approach
Review the existing services, identify duplicated or unsupported components, assess website and hosting security, backup and recovery, domain and email dependencies, cloud use and continuity requirements, then prioritise improvements around business impact.
Delivery
Technology inventory, hosting and website review, DNS and email mapping, backup and continuity recommendations, security improvements, cloud and infrastructure guidance and a practical support roadmap.
Outcome
A simpler and better-understood technology estate with clearer ownership, reduced dependency risk and a practical foundation for ongoing support and future growth.
CASE STUDY 06
SME Technology Consolidation & Resilience
Environment
Web, hosting, cloud, email, domains, backup and security services supporting a growing SME.
DNC DELIVERY APPROACH
Understand first. Design second. Change with evidence.
DNC engagements are built around understanding the real environment before prescribing the answer. That means combining architecture, engineering, security and operational evidence so recommendations are grounded in what is actually deployed and what the organisation needs to achieve.
1. Discover
Establish scope, current state, dependencies and business drivers.
2. Assess
Identify risk, constraints, gaps and viable technical options.
3. Design
Produce architecture, roadmap and implementation guidance.
4. Deliver & Validate
Support implementation, migration, remediation and technical assurance.
