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.
Hybrid Cloud: When It Makes Sense
Hybrid cloud can be a deliberate architecture choice, not simply a temporary stage between old and new platforms.
Understanding Your External Attack Surface
You cannot protect internet-facing systems effectively if you do not know what is exposed.
Oracle Database Upgrades: The Hidden Dependencies
A database upgrade can affect much more than the database itself. Compatibility and dependency checks should come first.
IAM: Least Privilege Without Operational Friction
Good identity design reduces risk without making legitimate administration unnecessarily difficult.
Infrastructure as Code: When Terraform Adds Real Value
Terraform is most valuable when it improves repeatability, reviewability and control rather than simply replacing manual clicks.
Cloud Cost Optimisation Starts with Architecture
Cloud savings are rarely achieved by discounts alone. Architecture, sizing and operational behaviour matter more.
RTO and RPO: Designing Recovery Around Business Need
Recovery objectives should be driven by business impact, not copied from a technical template.
Legacy Oracle Support: Stabilise Before You Modernise
Not every legacy Oracle estate can be migrated immediately. Stabilisation can reduce risk while the future plan is developed.
Landing Zones: What Good Cloud Foundations Look Like
A landing zone should make cloud adoption safer, repeatable and easier to govern.
Vulnerability Scanning Is Not the Same as a Security Assessment
Automated scanners are useful, but meaningful security assessment requires validation, context and prioritisation.
Oracle E-Business Suite Upgrades: Why Dependency Mapping Matters
An EBS upgrade is rarely just an application change. The surrounding dependencies often determine the real risk.
OCI Foundations: Compartments, IAM and Network Design
Good OCI architecture starts with clear tenancy structure, access boundaries and network design.
