Cloud Native Application Development on Microsoft Azure

A lifted-and-shifted application runs in the cloud but is still built like an on-premises system — one deployable unit on a server you manage. A cloud-native application is built out of the platform: small independently deployable services, packaged as containers or run as serverless functions, communicating through events and messages, scaling automatically, with infrastructure defined as code and observability built in. The practical test is whether you can deploy one part without redeploying the whole thing, and whether scale is automatic or a project. If it isn’t, it’s hosted, not cloud-native.

Usually not. Our default for containerised services and APIs is Azure Container Apps — serverless containers that scale to zero, without the operational weight of running a Kubernetes cluster. Azure Functions handles event-driven work. AKS is the right answer only when there’s genuine orchestration complexity that justifies it. For most mid-market products and platforms, the honest answer is not AKS, and choosing it by default is a common and expensive mistake.

.NET Aspire is Microsoft’s opinionated stack for building cloud-native applications. It wires in service discovery, health checks, configuration and OpenTelemetry observability out of the box, with a developer dashboard and a local-to-Azure development loop that deploys to Azure Container Apps via the Azure Developer CLI. In plain terms, it removes weeks of plumbing that teams used to hand-build and get subtly wrong — so more of the budget goes to the application and less to the scaffolding around it.

By building the discipline in from day one rather than bolting it on later — infrastructure as code with Bicep, automated pipelines in GitHub Actions, identity through Microsoft Entra ID and Managed Identity so there are no secrets in code, and observability through Application Insights from the first commit. After go-live, our managed application service keeps a dedicated Technical Lead on the environment in fortnightly sprints. The moving parts are real; the point is that they’re monitored, automated, and owned — not left to surprise you.

That’s exactly what the assessment is for. We weigh what you’re building against how it needs to scale, the experience you need, and what you’ll run for years — then match it to the right platform. Cloud-native fits when there’s real scale, a differentiated experience, intellectual property worth owning, or genuinely complex logic. A form, an approval, an internal line-of-business app or a simple portal is often a better fit as a Power App, Power Pages site or managed service, inside your existing Microsoft licensing. If the need is chat or an agent over your data, reusing our Q Platform usually beats a bespoke build. We’d rather point you to the simpler option than sell you a platform you don’t need.

We default to Australian Azure regions — Australia East and Australia Southeast — and confirm data-sovereignty requirements before designing. Identity runs through Microsoft Entra ID with Managed Identity so credentials aren’t stored in code, and secrets sit in Key Vault. For government and some education and not-for-profit workloads, IRAP, the Essential Eight and WCAG accessibility are treated as first-class design constraints, not afterthoughts.
