INSIGHTS
Technical Insight for Better Technology Decisions
Practical guidance from Data Network Computing across cloud architecture, Oracle, cyber security, legacy technology, migration and modernisation.
Our focus is on useful technical insight grounded in real architecture, engineering and operational experience.

WHAT WE WRITE ABOUT
Practical guidance for complex technology environments
DNC Insights is designed for technology leaders, architects, engineers and business owners who need clear guidance on real technical decisions rather than generic trend commentary.
Cloud Architecture & Engineering
OCI, AWS, Microsoft Azure and hybrid architecture, landing zones, networking, identity, Infrastructure as Code, resilience, migration and platform engineering.
Oracle & E-Business Suite
Oracle Database, EBS, OCI, upgrades, migrations, high availability, disaster recovery, architecture and operational support.
Legacy Oracle Support
Supportability, risk reduction, documentation, stabilisation, upgrade readiness and migration planning for older Oracle estates that still matter to the business.
Cyber Security & Ethical Hacking
Vulnerability assessment, authorised testing, cloud security, configuration review, attack surface, remediation and retesting.
Current-State Discovery & Architecture
How to reverse-engineer an existing estate, map dependencies, recover architecture knowledge and turn incomplete documentation into useful HLD and LLD inputs.
Migration & Modernisation
Planning migrations, understanding dependencies, target-state design, cutover and rollback, resilience, technical debt and practical modernisation sequencing.
DNC PERSPECTIVE
Useful, technical and grounded in the real environment
DNC Insights will focus on the decisions organisations actually face: what exists today, what is supportable, where risk sits, what should change first and how to design the next step without creating unnecessary complexity.
Evidence Before Assumption
Architecture and security decisions should start with evidence from the actual environment.
Practical Over Theoretical
Recommendations should be implementable, supportable and appropriate to the organisation.
Business Context Matters
Good technical design balances risk, resilience, cost, supportability and the pace of change the business can absorb.
TECHNICAL ARTICLES
DNC Weekly Insight
DNC Weekly Insight provides a practical technical article every Monday, covering cloud, Oracle, cyber security, architecture, migration and SME technology. The series begins on 5 January 2026 and is designed to build a useful, searchable knowledge library over time.
Initial article themes will include OCI current-state discovery, Oracle legacy support, landing-zone design, migration planning, cyber security assessment and architecture documentation.
Architecture Debt: Recognising the Cost of Deferred Decisions
Architecture debt builds when short-term decisions accumulate without a plan to revisit them.
Building an HLD from a Reverse-Engineered Environment
When documentation is incomplete, the first architecture task is often to reconstruct the environment before designing the future.
Prioritising Security Findings: Fix What Matters First
Severity scores are useful, but remediation priorities should also consider exposure, exploitability and business context.
SME Business Continuity: Protect the Services That Keep You Trading
Business continuity for SMEs should focus first on the small number of technology services the business cannot operate without.
Third-Party and MSP Ownership: Know Who Operates What
Complex environments often depend on multiple suppliers. Clear ownership is essential for support, security and recovery.
Database Migration Readiness: What to Check Before the Move
Database migration planning should start with compatibility, dependencies, data movement and a realistic cutover path.
FinOps for Technical Leaders: Cost Is an Architecture Signal
Cloud cost data can reveal architectural and operational problems, not just financial ones.
Why Security Retesting Matters After Remediation
A finding is not fully closed until the remediation has been validated in the real environment.
Identity Is the Cloud Control Plane
In cloud environments, identity permissions often provide more control than the network perimeter alone.
Patch, Upgrade or Modernise? Choose the Right Level of Change
Not every ageing platform needs the same response. The right choice depends on risk, supportability and business timing.
What to Include in a Technology Architecture Review
A useful architecture review should connect technical design with risk, operations and business objectives.
Cloud Network Segmentation: Reduce the Blast Radius
Network segmentation should reflect trust boundaries, application flows and operational need.
