Building and Deploying Microservices on Azure Kubernetes Service

This guide provides a comprehensive walkthrough for building, deploying, and managing a microservices architecture on Azure Kubernetes Service (AKS). Explore best practices, common patterns, and essential tools for a successful microservices implementation.

Project Overview

The sample demonstrates a set of interconnected microservices, each handling a specific business capability. We cover aspects such as service discovery, inter-service communication, data persistence, and monitoring.

Key Technologies Used

Azure Kubernetes Docker .NET Core PostgreSQL Redis Nginx

Features

  • Containerization: All services are packaged as Docker containers.
  • Orchestration: Managed deployment and scaling using AKS.
  • Service Mesh (Optional): Integration with Istio for advanced traffic management and observability.
  • CI/CD Pipeline: Automated build, test, and deployment with Azure DevOps or GitHub Actions.
  • Observability: Integrated logging, metrics, and tracing using Prometheus, Grafana, and Jaeger.
  • Scalability: Horizontal Pod Autoscaler (HPA) for dynamic scaling.

Getting Started

Follow these steps to set up the sample environment:

Prerequisites

  • Azure Subscription
  • Azure CLI installed and configured
  • kubectl installed
  • Docker installed

Deployment Steps

  1. Create an Azure Kubernetes Service (AKS) cluster.
  2. Clone the repository: git clone https://github.com/Azure-Samples/aks-microservices.git
  3. Build and push Docker images to Azure Container Registry (ACR).
  4. Apply Kubernetes manifests: kubectl apply -f kubernetes/
