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.
DNS, Email and Hosting: The Hidden SME Dependencies
Small business technology often depends on a few critical services that are easy to overlook until they fail.
Change Windows and Rollback: Plan the Decision Points
A rollback plan is only useful if teams know exactly when to use it.
Oracle High Availability: Design Around the Service
Database availability is only one part of keeping an Oracle service available.
Multi-Cloud: Strategy or Accident?
Using more than one cloud can be sensible, but only when the operating model is as deliberate as the technology choice.
Web Application Security for SMEs: Start with the Basics
SME websites and web applications often carry real business risk even when they are not complex enterprise systems.
Legacy Systems: Document Before You Change
The less documentation a legacy platform has, the more important discovery becomes before making major changes.
Backups Are Not the Same as Disaster Recovery
Backups protect data. Disaster recovery protects the ability to restore a service within agreed business objectives.
Migration Runbooks: Turning Architecture into Controlled Change
A migration runbook converts the design into a sequence teams can execute, validate and reverse if required.
Cloud Guardrails: Security Without Blocking Delivery
Cloud guardrails should prevent high-risk configuration while still allowing teams to work efficiently.
HLD vs LLD: What Each Document Should Do
High-level and low-level designs solve different problems. Both should be grounded in the real environment.
Logging and Monitoring: Design for Evidence
Monitoring should help teams answer what happened, when it happened and what changed.
Oracle EBS on OCI: More Than Rehosting
Moving Oracle E-Business Suite to OCI should consider the whole service, not just where the servers run.
