|This architecture provides guidance for designing a carrier-grade solution for a telecommunication use case. The design choices focus on high reliability by minimizing points of failure and ultimately overall downtime using native Azure capabilities.
Deploy highly available applications
The following table includes articles that describe how to deploy your applications for high availability using a combination of Azure Networking services.
|Multi-region N-tier application)
|Describes a multi-region N-tier application that uses Traffic Manager to route incoming requests to a primary region and if that region becomes unavailable, Traffic Manager fails over to the secondary region.
|Multitenant SaaS on Azure
|Uses a multi-tenant solution that includes a combination of Front Door and Application Gateway. Front Door balances traffic across regions. Application Gateway routes and load-balances traffic internally in the application to the various services that satisfy the client business needs.
|Multi-tier web application built for high availability and disaster recovery
|Deploys resilient multi-tier applications built for high availability and disaster recovery. If the primary region becomes unavailable, Traffic Manager fails over to the secondary region.
|Application Gateway Ingress Controller (AGIC) with a multitenant Azure Kubernetes Service
|Protect your Azure Kubernetes Service (AKS) cluster with Application Gateway Ingress Controller (AGIC) and Web Application Firewall (WAF). AGIC is a Kubernetes application that makes it easy to manage an Application Gateway instance in your AKS cluster.
|IaaS: Web application with relational database
|Describes how to use resources spread across multiple zones to provide a high availability architecture for hosting an Infrastructure as a Service (IaaS) web application and SQL Server database.
|Sharing location in real time using low-cost serverless Azure services
|Uses Azure Front Door to provide higher availability for your applications than deploying to a single region. If a regional outage affects the primary region, you can use Front Door to fail over to the secondary region.
|Highly available network virtual appliances
|Shows how to deploy a set of network virtual appliances (NVAs) for high availability in Azure.
|Multi-region load balancing with Traffic Manager and Application Gateway
|Describes how to deploy resilient multi-tier applications in multiple Azure regions, in order to achieve availability and a robust disaster recovery infrastructure.
|Scalable and secure WordPress on Azure
|Describes how to deploy a scalable and secure WordPress application on Azure. The architecture uses Azure Cloud Delivery Network (CDN) to cache static content. The CDN uses an Azure Load Balancer as the origin to retrieve content from the WordPress application.
|Azure Firewall - Well-Architected Framework
|Architectural best practice for Azure Firewall. This guide covers the five pillars of architecture excellence: cost optimization, operational excellence, performance efficiency, reliability, and security.
|Expose Azure Spring Apps through a reverse proxy
|Describes how to use a reverse proxy service such as Azure Application Gateway or Azure Front Door to expose Azure Spring Cloud applications to the internet. By placing a service in front of Azure Spring Apps you can protect, load balance, route and filter requests based on your business needs.
|Oracle database migration to Azure
|Describes how to migrate an Oracle database to Azure using Oracle Active Data Guard. The architecture uses Azure Load Balancer to load balance traffic to the Oracle database.

|Discusses a collection of Azure best practices to enhance your network security.
|Azure Firewall Architecture Guide
|Provides a structured approach for designing highly available firewalls in Azure using third-party virtual appliances.
|Implement a secure hybrid network
|Describes an architecture that implements a DMZ, also called a perimeter network, between the on-premises network and an Azure virtual network. All inbound and outbound traffic passes through Azure Firewall.
|Secure and govern workloads with network level segmentation
|Describes the three common patterns used for organizing workloads in Azure from a networking perspective. Each of these patterns provides a different type of isolation and connectivity.
