Infrastructure Deployment Plan

This document outlines a comprehensive plan for deploying a robust infrastructure that supports web applications across various environments. The plan focuses on setting up load-balanced web servers, configuring SQL databases with redundancy, and implementing advanced traffic management and security measures.

Steps for Deployment

Provision Load-Balanced IIS Servers

* The first step involves setting up two Internet Information Services (IIS) servers for each environment: development (dev), testing (test), and production (prod). These servers will be configured in a load-balanced setup to ensure high availability and reliability. Load balancing distributes incoming network traffic across multiple servers, preventing any single server from becoming a bottleneck and ensuring that the application remains responsive even under high load conditions.

Set Up SQL Databases

* Configure SQL databases with geo-redundancy to ensure failover capabilities. Geo-redundancy involves replicating data across multiple geographic locations, which enhances data availability and disaster recovery. In the event of a failure in one location, the system can automatically switch to a backup location, minimizing downtime and data loss. This setup is crucial for maintaining business continuity and ensuring that applications can access data without interruption.

Implement Azure Front Door

* Utilize Azure Front Door to manage and optimize traffic routing across the web application. Azure Front Door is a scalable and secure entry point for fast delivery of your global applications. It provides load balancing, SSL offloading, and application acceleration. Additionally, it includes a Web Application Firewall (WAF) to protect against common web vulnerabilities and attacks, enhancing both security and performance. This setup ensures that users experience fast and secure access to the application, regardless of their geographic location.
