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.
Security Logging and Monitoring: What Should You Actually Collect?
Effective security monitoring is not about collecting every possible log. It is about collecting the evidence needed to detect, investigate and respond to meaningful events.
AWS VPC Endpoints: Design Private Service Access Without Blind Spots
Private AWS service access needs more than an endpoint: design DNS, routes, IAM, resilience and cost together.
Technical Debt in Cloud Platforms: How It Builds Up and Why It Matters
Cloud technical debt builds when temporary configurations, manual processes and short-term decisions become permanent parts of the platform.
Why Network Segmentation Still Matters in Modern Cloud Environments
Cloud networking has changed, but segmentation still matters because it limits unnecessary communication, reduces attack paths and makes security boundaries easier to understand.
Oracle E-Business Suite on OCI: What a Good Architecture Should Include
A good Oracle E-Business Suite architecture on OCI should balance application performance, database resilience, security, connectivity, recoverability and operational simplicity.
Identity Is the New Perimeter: Designing IAM for Cloud Environments
Cloud security increasingly depends on identity. Good IAM design controls who and what can access resources, how privilege is granted and how access is reviewed.
Cloud Architecture Reviews: What Should You Actually Be Checking?
A cloud architecture review should examine more than diagrams. It should test identity, networking, resilience, security, observability, automation and cost against business needs.
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.
