Welcome to Azure Mission-Critical Online Reference Implementation

Azure Mission-Critical is an open source project that provides a prescriptive architectural approach to building highly-reliable cloud-native applications on Microsoft Azure for mission-critical workloads. This repository contains a Fully Functional Production-Ready Mission-Critical Reference Implementation, intended to provide a solution oriented basis to showcase mission-critical application development on Microsoft Azure, leveraging Azure-native platform capabilities to maximize reliability and operational effectiveness. More specifically, the reference implementation consists of:

• Design and implementation guidance to help readers understand and use the Azure Mission-Critical design methodology in the context of a particular industry scenario.
• Production-ready technical artifacts including Infrastructure-as-Code (IaC) resources and Continuous-Integration/Continuous-Deployment (CI/CD) pipelines (GitHub and Azure DevOps) to deploy an Mission-Critical application with mature end-to-end operational wrappers.

This repository contains the technical artifacts and in-depth documentation of the reference implementation for an Mission-Critical "online" scenario, i.e. a workload which does not require direct connectivity to other company resources (such as via a hub-and-spoke model). The pipeline deploys the application Azure Subscription security and compliance guardrails and has no network connectivity requirements. It will be used if the Mission-Critical application is access over a public endpoint without additional dependencies to other company resources.
