Your core system was built years ago. It runs on hardware or hosting few people want to touch. Only one or two staff understand it fully, and every request for a change triggers a risk conversation. Meanwhile the board asks about security and resilience, teams ask for new features, and competitors keep shipping capabilities you cannot match.
Searching for cloud infrastructure advice often produces a wall of generic claims. Every provider talks about “scalable” and “secure”. Very few show what was actually built, for whom, on which platform, and why.
This updated article takes a different approach. It draws on C9’s latest detailed case studies from Australian organisations where custom software was designed, hosted or modernised using Microsoft Azure, Amazon Web Services, Microsoft 365 / Power Platform and other modern infrastructure approaches. The projects are grouped by industry and outcome so you can locate the examples closest to your own situation.
A cloud infrastructure case study shows how an organisation used cloud platforms such as Microsoft Azure, Amazon Web Services or Microsoft 365 to host, store, integrate and secure a business system, including the problem it solved and the technology used.
All details below are drawn from C9’s case-study documentation and are therefore vendor-reported. Outcomes are mostly qualitative; quantified results are clearly attributed. Treat the material as evidence of capability, not as a guarantee of identical results for your organisation.
Why the Wrong Cloud Decision Hurts
The real cost of a poor infrastructure decision rarely appears on the monthly bill. It shows up elsewhere:
- Systems that cannot grow. A platform designed for one team struggles when it must serve multiple research cohorts, an entire industry, a franchise network or multi-depot operations.
- Sensitive data in the wrong place. Clinical research data, investor applications, water entitlements, membership records and supplier performance data require controlled access and audit trails—not shared folders or ageing servers.
- Slow, manual processes. When data lives in spreadsheets, email threads or disconnected systems, reporting takes weeks and decisions wait.
- Vendor and skills risk. If only one supplier or one person understands the setup, you have a dependency rather than a capability.
- Decisions made without proof. Choosing a platform from marketing language alone is how organisations end up with rework, frustration and board-level questions.
Australian organisations also operate under the Privacy Act and Notifiable Data Breaches scheme. Data residency, access controls and auditability are commercial and regulatory requirements. Real project examples cut through the noise by showing what was built, what it ran on, and what the client was trying to achieve.
What Cloud and Infrastructure Integration Means in Practice
In these projects, cloud and infrastructure integration meant connecting four practical elements:
| Element |
Plain-English meaning |
Examples from the case studies |
| Hosting |
Where the application and its APIs run |
Azure App Service / Cloud Services / VMs, AWS EC2, Heroku, Microsoft 365 / Power Platform, modern Windows Server + SQL environments |
| Storage |
Where files and documents are kept |
AWS S3 for large research files, SharePoint Online, controlled document repositories |
| Integration |
How the system talks to other systems |
Salesforce / Heroku Connect, HL7, wearable device APIs, SAP/ERP sync, Power BI, DocuSign, Able Baker, Xero, Active Directory |
| Security |
How access is controlled and recorded |
Multi-factor authentication, role- and company-scoped access, audit logging, directory- based authentication, controlled onboarding |
These are custom software solutions built or modernised by C9 and hosted on major platforms. They are not examples of large-scale cloud migration programmes or pure managed-hosting contracts. The infrastructure layer exists to support the business application.

Microsoft Azure, Microsoft 365 and Related Projects
Government and regulated environments
The Office of the Information Commissioner (Queensland) needed to replace email-driven, spreadsheet-tracked internal processes with structured, auditable digital workflows. C9 implemented Microsoft Power Platform solutions (Power Apps, Power Automate, Microsoft Approvals, Teams and SharePoint) entirely within the client’s Microsoft 365 environment. Key workflows included FTE change and business-case management, flexible working arrangements, procurement and related governance processes. Role-based security, SharePoint permissions and auditable approval histories were built in. The approach leveraged existing Microsoft investment, kept data under organisational control, and created a reusable framework for further process digitisation.
Tasmanian Irrigation required a secure, auditable Water Entitlements Register. C9 defined a web-based system on Azure App Service supporting historical “as-at” views, controlled change management, approval gating, document generation and mandatory audit capture. The platform strengthens registrar capability and supports future water-operating-system development.
Health, research and community
The Clinician Support System supports clinical research by capturing patient data from wearable devices (Fitbit, Garmin) and structured surveys. It delivers a mobile app for patients and a secure web portal for clinicians and project administrators, with multi-role access, project-scoped messaging, survey management, session scheduling and resource distribution. Controlled onboarding and project-scoped visibility provide governance. The platform reduces manual administration and improves visibility across concurrent research cohorts.
Brisbane Seniors Online replaced a legacy Microsoft Access MIS with a modern .NET application backed by SQL Server. The project included structured data migration, cleanup of obsolete tables, and a foundation designed for reputable modern infrastructure providers. Outcomes include elimination of Access dependency, improved stability and a scalable base for future phases.
For Life, OzeTriage / Southern Health and related health platforms continue to demonstrate Azure-hosted secure portals and workflow systems with strong role-based controls and auditability.
Other Microsoft-centric and hybrid examples
Studio Pilates and Fit Merchandising illustrate embedded Power BI analytics within secure portals. Atkins Global remains a clear quantified Azure example (C9-reported 92% reduction in invoicing backlogs after building a local data warehouse and portal synced with a UK ERP on Azure virtual machines).
Amazon Web Services, Heroku and Multi-Tenant SaaS Projects
City Finance extended its existing Salesforce-based loan platform with a native mobile application. The solution uses Heroku, Heroku Connect for bidirectional synchronisation with Salesforce, and PostgreSQL. Customers can view applications and loans, upload documents, accept contracts, request statements and manage payments from mobile devices, with secure authentication (including PIN and one-time password options). The architecture maintains data accuracy while adding always-on mobile accessibility.
HuddlePoint required production-ready SaaS subscription, trial and billing capability. C9 implemented end-to-end trial lifecycle management, upgrade/downgrade logic, prorata calculations, Stripe and PayPal integrations, and CRM visibility. The multi-tenant framework supports controlled free trials, automated lifecycle transitions and scalable monetisation without embedding core billing rules inside third-party payment platforms.
CSIRO Data61 projects continue to illustrate AWS strengths: extensive S3 integration for controlled release of sensitive research files (including multi-GB uploads with chunking and validation) and a secure Early Adopter Program portal designed for large datasets and company-scoped collaboration while remaining independent of internal CSIRO systems.
Legacy Modernisation and Critical Systems Resilience
Jago’s Classic ASP platform was redeveloped onto ASP.NET MVC, Web API and SQL Server with Entity Framework, version control, database migration tooling and centralised error logging. The work established modern development practices and a maintainable foundation for ongoing feature delivery.
Timberlink Australia’s Bell Bay Sawmill relies on tightly integrated supply systems that process tens of millions of dollars annually. C9 provided operational support, improved backup and resilience measures, documented critical workflows, and defined a formal modernisation roadmap. The engagement reduced exposure to data loss and system failure while establishing a structured path away from fragile legacy architecture and manual spreadsheet calculations.
These projects demonstrate that cloud and infrastructure work often begins with stabilisation, risk reduction and clean architecture before any large-scale migration.

Three practical lessons for executives
- Match the platform to the workload. Azure and Microsoft 365 appear frequently for hosted applications, workflow automation and analytics; AWS and Heroku are used for large-file storage, selected application hosting and Salesforce-centric mobile extensions. The choice follows requirements.
- Build security and governance into the application from day one. Multi-factor or directory authentication, role- or project-scoped access, audit logging and controlled onboarding appear repeatedly. Ask for them early.
- Start from a real business problem. Every project began with fragmented systems, manual processes, data risk or end-of-life technology—not with a technology preference.
What These Case Studies Do Not Show
To keep the material useful and trustworthy:
- No published uptime, cost-saving or performance figures for the cloud environments themselves.
- No large-scale on-premise-to-cloud migration programmes. The projects are custom software hosted or modernised on cloud platforms.
- Limited public detail on DevOps pipelines, DNS or certificate management.
- Some projects emphasise application and data design more than the specific cloud services used.
If any of those factors are critical to your decision, ask C9 directly for relevant experience and evidence.
Six Questions to Ask Before Choosing a Cloud Approach
- Which single system causes the most risk or delay in the business today?
- Where does the sensitive data live, and who can currently see it?
- How many users, organisations or cohorts will rely on this system in three years?
- Which systems must it integrate with, and are they cloud-friendly?
- What evidence will your board, auditors or regulators expect?
- Who will understand and maintain the solution after the build?
Why C9 Compares Differently
Australia has no shortage of software developers. What separates C9 is the breadth of work already delivered and the way knowledge is transferred.
| What separates C9 |
Why it matters |
| Custom software, integration and database expertise |
Cloud hosting sits alongside the applications and data it supports; C9 builds both |
| Documented projects across regulated and industry settings |
Health, research, government, agriculture, finance, franchise networks and industrial systems |
| Local presence with broader engineering capacity |
Oversight and communication that Australian executives expect |
| Knowledge transfer as part of delivery |
Your team understands what was built and is not locked into a single supplier |
| Track record |
C9’s website references 350+ projects and 19 years of delivery |
C9 designs, builds and hosts custom software and integrations on Azure, AWS, Microsoft 365 and related platforms. Claims about migration programmes, zero downtime, Google Cloud delivery, specific certifications or guaranteed savings should be confirmed directly with the team and supported by evidence relevant to your workload.
Frequently Asked Questions
What is a cloud infrastructure case study?
A written example showing how an organisation used cloud platforms to host, store, integrate and secure a business system, including the problem and the technology used.
Which cloud platforms do these C9 case studies use?
Microsoft Azure, Amazon Web Services, Microsoft 365 / Power Platform and Heroku appear most frequently. Several projects use hybrid patterns.
Do these case studies prove cost savings or uptime?
No. The documentation describes what was built and hosted. Quantified results (such as the Atkins Global backlog reduction) are clearly attributed as C9-reported.
Is Azure, AWS or Microsoft 365 better for my business?
It depends on your workload, existing integrations, team skills and data requirements. These projects show all three used successfully for different purposes.
Can C9 migrate our existing systems to the cloud?
Ask C9 directly. The case studies in this article describe custom software hosted or modernised on cloud platforms; they do not document large-scale migration programmes.
How do we get started?
Identify one system that is constraining the business, map its data and users, and book a scoping conversation to compare options before committing budget.
Conclusion and Next Step
Choosing cloud infrastructure becomes clearer when you can see what others actually built. These updated case studies demonstrate Azure, AWS, Microsoft 365 / Power Platform and modern hosting platforms used to host applications, store sensitive files, support multi-tenant and multi-role platforms, and embed security and governance controls across Australian organisations in health, research, government, agriculture, finance and industrial settings.
The consistent pattern is practical: start with a real business problem, match the platform to the workload, build security and auditability in from day one, and ensure your own people understand the result.
Have a system that is outgrowing its current hosting, or a project that needs a secure cloud home?
Talk to C9 about your Cloud & Infrastructure needs. We will help you scope one workload, review its data and integrations, and recommend whether Azure, AWS, Microsoft 365 or another approach suits the job.
