Voxxed Days SG - 2018

Repository for Code related to Voxxed Days Singapore 2018 talk on Modernize Application Developement with Highly Scalable Architecture using Docker and Azure.

The application showcases the journey of developer from containerizing application to testing locally using a single node Minikube cluster. It then goes into overdrive mode with deployment to managed Kubernetes cluster in Azure. Icing on the cake is the monitoring solution provided by Azure Container Monitoring.

The code structure is organized as

• src : contains the source code for the VDSG2018 solution
  • TechTalksWeb : Contains source code for the MVC web frontend named TechTalksWeb
  • TechTalksAPI : Contains source code for the backend API named TechTalksAPI. The API also acts as a producer of RabbitMQ messages.
  • TechTalksDB : Contains the initialization script for TechTalksDB database and the Dockerfile
  • TechTalksMQProcessor : Contains code for onsuming events and writing to the SQL database
  • TechTalksELKProcessor : Contains code for consuming events and writing them to a Elastic Search Index
• DotnetCLI : Contains the dotnet CLI commands for creating solution, projects and adding external packages
• Powershell : contains the Powershell scripts for managing Kubernetes deployments and AKS cluster
• k8s : Contains the Kubernetes Manifest files for Minikube, AKS with containerized SQL Server linux and AKS-ManagedSQL running a managed SQL Database in Azure.

Application deployment scenarios

The application with all the components deployed via containers will look as

Database persistance is handled by externalizing the SQL server state using Persistenet Volumes

The application uses queue based load levelling pattern

For a production grade scenario, the application uses managed SQL instance instead of a containerized version of SQL Server 2017

For monitoring, Prometheus and Grafana provide metrics collection and visualization
