I'd like to build a typical Todo List Application: a simple productivity tool that allows users to create, manage, and track tasks or to-do items. Key features of the Todo List application include the ability to add, edit, and delete tasks, set due dates and reminders, categorize tasks by project or priority, and mark tasks as complete. The Todo List applications also offer collaboration features, such as sharing tasks with others or assigning tasks to team members. Additionally, the Todo List application will offer offer mobile and web-based interfaces, allowing users to access their tasks from anywhere. Use C# as the language. The app needs to be deployed to Azure, be highly performant, cost effective and secure, following the rules of Well Architected Framework.

# Todo List Application

## Overview

The Todo List Application is a sophisticated productivity tool that assists users with task organization, management, and tracking. This application addresses the needs of a wide range of users, from individuals to large teams, providing a seamless experience across multiple platforms and leveraging cloud capabilities to ensure accessibility, performance, and security.

## Main Features

- **Task Management**: Create, edit, and delete tasks with ease.
- **Due Dates and Reminders**: Assign due dates and set reminders to never miss a deadline.
- **Categorization**: Sort tasks by project or priority for better organization.
- **Task Completion**: Check off completed tasks and visualize your achievements.
- **Collaboration**: Share and assign tasks to team members for effective teamwork.
- **Cross-Platform Accessibility**: Use the application on mobile devices and via web browsers.
- **Azure-Hosted**: Hosted on Azure for high performance, cost efficiency, and security in adherence to Well-Architected Framework principles.

## Architecture and Guidelines

Adhering to the architectural guidelines, the Todo List Application is designed with the following considerations:

### Health Modeling and Observability

The application implements a robust health model, with metrics and logging practices defined to ensure operational maturity. Azure Monitor and Application Insights are configured to provide real-time observability into the application's health and performance.

### Deployment and Testing

CI/CD pipelines are managed with Azure DevOps to facilitate zero-downtime deployments. Testing stages ensure that application health is maintained during updates, with automated rollback procedures in place if anomalies are detected.

### Security

The application is secured using Azure Active Directory for authentication, Azure Key Vault for managing secrets, and network security groups to control access. Regular security audits and adherence to Azure security best practices ensure the application's reliability against threats.

### Operational Procedures

The adoption of DevOps methodologies ensures consistent and effective operational procedures. Infrastructure as Code (IaC) using Azure Resource Manager (ARM) templates or Terraform scripts automate the provisioning and management of Azure resources.

### Baseline Architecture

The application follows the baseline architecture of an internet-facing application, providing a scalable, cloud-native solution on Microsoft Azure. The workload is accessible through a public endpoint with additional network controls to block unauthorized internet access.

## Security and Application Insights

Application Insights is configured with the following best practices to handle security and customer data:

- **Sensitive Data**: Review and minimize the capture of customer data within telemetry to comply with privacy policies.
- **Data Retention**: Configure data retention policies in Application Insights to manage the lifecycle of stored data.
- **Access Control**: Limit access to Application Insights data to authorized personnel using role-based access control (RBAC).
- **Audit Logs**: Enable and review audit logs to monitor for any unauthorized access or anomalies in usage patterns.

## Cost Optimization

To optimize costs while using Application Insights:

- **Data Volume**: Adjust the data sampling rate to balance between detail and cost.
- **Alerts**: Set up alerts to monitor for unusual spikes in resource usage that could indicate inefficiencies or potential cost overruns.
- **Usage Analysis**: Regularly review the Application Insights usage and performance reports to identify areas for cost optimization.

## Running the Application
