Cross-Region Resiliency for Ecommerce Reference Application
Authors: Radu Dilirici (radudilirici@microsoft.com) Ioan Dragan (ioan.dragan@microsoft.com) Ciprian Amzuloiu (camzuloiu@microsoft.com) Introduction The initial Resilient Ecommerce Reference Application demonstrated the best practices to achieve regional resiliency using Azure’s availability zones. Expanding on this foundation, in the current article we aim to achieve cross-region resiliency, ensuring high availability and disaster recovery capabilities across multiple geographic regions. This article outlines the enhancements made to extend the application into a cross-region resilient architecture. The app is publicly available on GitHub and can be used for educational purposes or as a starting point for developing cross-region resilient applications. Overview of Cross-Region Enhancements The main architectural change needed to extend the application to a cross-region approach was to replicate the existing zonal resilient setup across multiple Azure regions and enable failover mechanisms for seamless operation during regional outages. Below is a visual representation of the new architecture: Component Details Networking Architecture The networking architecture has been extended to support cross-region traffic management. Azure Front Door serves as the global entry point, routing traffic to the primary region. In case of a disaster, the traffic is redirected to the secondary region. Global Virtual Network Peering is used to link together the virtual networks of the two regions. This enables the Redis Caches and SQL Databases to communicate with each other, keeping them in sync and allowing them to perform the switchover procedure. This change allowed us to remove the previous DNS zone groups. Service Endpoints provide secure and direct connectivity with the Azure Virtual Network for the SQL Databases and Key Vault. They allow access to these services without exposing them to the public internet, reducing the attack surface and enhancing security. Storage Architecture Azure SQL Database, Azure Cache for Redis and Azure Container Registry now employ geo-replication to ensure data availability across regions. Azure Key Vault is cross-region resilient by default as it automatically replicates the data to the Azure paired region. Read more about geo-replication for Azure SQL and Azure Cache for Redis. Compute Architecture The Azure Kubernetes Service (AKS) clusters are deployed across multiple regions , with each cluster running in a minimum of three Availability Zones. The autoscaling and load distribution mechanisms from the original setup are retained, ensuring optimal performance and high availability. Read more about multi-region AKS clusters. The application supports both Active-Active and Active-Passive states, determined by the AKS configuration. In an Active-Active state, the secondary AKS is always running, providing a faster switchover at the cost of higher expenses. Conversely, in an Active-Passive state, the secondary AKS is deployed but not started, reducing costs but resulting in a slower switchover. Additionally, the secondary AKS can be configured with fewer resources for further cost savings. Failover The failover procedure consists of migrating the compute, storage and networking services to the secondary region. Firstly, the AKS cluster is started in the secondary region. In an Active-Active configuration, this step is skipped as the cluster is already running. Then, the SQL Database and Redis Cache are synced with their replicas and the secondary instances are elevated to the primary role. The traffic is reconfigured through the Front Door profile to hit the services in the new region. Controlled failover is crucial for keeping systems running smoothly during a disaster. When things go wrong, an on-call engineer can start the failover process to quickly move operations to a backup system, minimizing any potential issues. Follow this guide to start experimenting with failover over the reference application.Automating End-to-End testing with Playwright and Azure Pipelines

This is typically achieved through using AI to provide data-driven insights that facilitate personalized or unique customer interactions, to enable customer access to a wider range of information, while improving search queries and making data more accessible. You can check out a sample architecture for building your copilot below. DocuSign, a leader in e-signature solutions with 1.6 million global customers, pioneered an entirely new category of agreement management designed to streamline workflows and created Docusign Intelligent Agreement Management (IAM). The IAM platform uses sophisticated multi-database architecture to efficiently manage various aspects of agreement processing and management. At the heart of the IAM platform is Azure AI, which automates manual tasks and processes agreements using machine learning models. "We needed to transform how businesses worked with a new platform. With Docusign Intelligent Agreement Management, built with Microsoft Azure, we help our customers create, commit to, manage, and act on agreements in real-time.” — Kunal Mukerjee, VP, Technology Strategy and Architecture, Docusign The workflow begins with agreement data stored in an Azure SQL Database and is then transferred through an ingestion pipeline to Navigator, an intelligent agreements repository. In addition, the Azure SQL Database Hyperscale service tier serves as the primary transactional engine, providing virtually unlimited storage capacity and the ability to scale compute and storage resources independently. Inspiration #4: Optimize employee workflows With AI-powered apps, businesses can organize unstructured data to streamline document management and information, leverage natural language processing to create a conversational search experience for employees, provide more contextual information to increase workplace productivity and summarize data for further analysis. Increasingly we have seen solutions such as employee chatbots for HR, professional services assistants (legal/tax/audit), analytics and reporting agents, contact center agent assistants, and employee self-service and knowledge management (IT) centers. It’s essential to note that adequate prompt engineering training can improve employee queries, and your team should examine the capability of integrating copilot with other internal workloads; lastly, make sure your organization implements continuous innovation and delivery mechanisms to support new internal resources and optimize chatbot dialogs. Improving the lives of clinicians and patients Medigold Health, one of the United Kingdom’s leading occupational health service providers, migrated applications to Azure OpenAI Service, with Azure Cosmos DB for logging and Azure SQL Database for data storage, achieving the automation of clinician processes, including report generation, leading to a 58% rise in clinician retention and greater job satisfaction.

"We knew with Microsoft and moving our AI workloads to Azure, we’d get the expert support, plus scalability, security, performance, and resource optimization we needed.” — Alex Goldsmith, CEO, Medigold Health Inspiration #5: Prevent fraud and detect anomalies Increasingly, organizations leverage AI to identify suspicious financial transactions, false account chargebacks, fraudulent insurance claims, digital theft, unauthorized account access or account takeover, network intrusions or malware attacks, and false product or content reviews. If your company can use similar designs, take a glance at a sample architecture for building an interactive fraud analysis app below. Azure Cosmos DB. Transactional data is available for analytics in real-time (HTAP) using Synapse Link. All the other financial transactions such as stock trading data, claims, and other documents are integrated with Microsoft Fabric using Azure Data Factory. This setup allows analysts to see real-time fraud alerts on a custom dashboard. Generative AI denoted here uses RAG, with Azure OpenAI Service of the LLM, and Azure AI Search as the retrieval system. Fighting financial crimes in the gaming world Kinectify, an anti-money laundering (AML) risk management technology company, built its scalable, robust, Microsoft Azure-powered AML platform with a seamless combination of Azure Cosmos DB, Azure AI Services, Azure Kubernetes Service, and the broader capabilities of Azure cloud services. "We needed to choose a platform that provided best-in-class security and compliance due to the sensitive data we require and one that also offered best-in-class services as we didn’t want to be an infrastructure hosting company. We chose Azure because of its scalability, security, and the immense support it offers in terms of infrastructure management.” — Michael Calvin, CTO, Kinectify With the new solutions in place, Kinectify detects 43% more suspicious activities achieves 96% faster decisions, and continues to champion handling a high volume of transactions reliably and identifying patterns, anomalies, and suspicious activity. Inspiration #6: Unlock organizational knowledge We have seen companies building intelligent apps to surface insights from vast amounts of data and make it accessible through natural language interactions. Teams will be able to analyze conversations for keywords to spot trends and better understand your customers. Common use cases can include knowledge extraction and organization, trend and sentiment analysis, curation of content summarization, automated reports, and research generation. Below is a sample architecture for enterprise search and knowledge mining. H&R Block, the trusted tax preparation company, envisioned using generative AI to create an easy, seamless process that answers filers’ tax questions, maintains safeguards to ensure accuracy, and minimizes the time to file. Valuing Microsoft’s leadership in security and AI and the longstanding collaboration between the two companies, H&R Block selected Azure AI Foundry and Azure OpenAI Service to build a new solution on the H&R Block platform to provide real-time, reliable tax filing assistance. By building an intelligent app that automates the extraction of key data from tax documents, H&R Block reduced the time and manual effort involved in document handling. The AI-driven solution significantly increased accuracy while speeding up the overall tax preparation process. "We conduct about 25 percent of our annual business in a matter of days.” — Aditya Thadani, Vice President, H&R Block Through Azure’s intelligent services, H&R Block modernized its operations, improving both productivity and client service and classifying more than 30 million tax documents a year. The solution has allowed the company to handle more clients with greater efficiency, providing a faster, more accurate tax filing experience. Inspiration #7: Automate document processing Document intelligence through AI applications helps human counterparts classify, extract, summarize, and gain deeper insights with natural language prompts. When adopting this approach, organizations are recommended to also consider prioritizing the identification of tasks to be automated, and streamline employee access to historical data, as well as refine downstream workload to leverage summarized data. Here is a sample architecture for large document summarization. Volve Group, one of the world’s leading manufacturers of trucks, buses, construction equipment, and marine and industrial engines, streamlined invoice and claims processing, saving over 10,000 manual hours with the help of Microsoft Azure AI services and Azure AI Document Intelligence.

Overview With the introduction of Azure AI Foundry, integrating various AI services to streamline AI solution development and deployment of Agentic AI Workflow solutions like multi-modal, multi-model, dynamic & interactive Agents etc. has become more efficient. The platform offers a range of AI services, including Document Intelligence for extracting data from documents, natural language processing and robust machine learning capabilities, and more. Microsoft Fabric further enhances this ecosystem by providing robust data storage, analytics, and data science tools, enabling seamless data management and analysis. Additionally, Copilot and GitHub Copilot assist developers by offering AI-powered code suggestions and automating repetitive coding tasks, significantly boosting productivity and efficiency. Objectives In this use case, we will use monthly electricity bills from the utilities' website for a year and analyze them using Azure AI services within Azure AI Foundry. The electricity bills is simply an easy start but we could apply it to any other format really. Like say, W-2, I-9, 1099, ISO, EHR etc. By leveraging the Foundry's workflow capabilities, we will streamline the development stages step by step. Initially, we will use Document Intelligence to extract key data such as usage in kilowatts (KW), billed consumption, and other necessary information from each PDF file. This data will then be stored in Microsoft Fabric, where we will utilize its analytics and data science capabilities to process and analyze the information. We will also include a bit of processing steps to include Azure Functions to utilize GitHub Copilot in VS Code. Finally, we will create a Power BI dashboard in Fabric to visually display the analysis, providing insights into electricity usage trends and billing patterns over the year. Utility Invoice sample Building the solution Depicted in the picture are the key Azure and Copilot Services we will use to build the solution. Set up Azure AI Foundry Create a new project in Azure AI Foundry. Add Document Intelligence to your project. You can do this directly within the Foundry portal. Extract documents through Doc Intel Download the PDF files of the power bills and upload them to Azure Blob storage. I used Document Intelligence Studio to create a new project and Train custom models using the files from the Blob storage. Next, in your Azure AI Foundry project, add the Document Intelligence resource by providing the Endpoint URL and Keys. Data Extraction Use Azure Document Intelligence to extract required information from the PDF files. From the resource page in the Doc Intel service in the portal, copy the Endpoint URL and Keys. We will need these to connect the application to the Document Intelligence API. Next, let’s integrate doc intel with the project. In the Azure AI Foundry project, add the Document Intelligence resource by providing the Endpoint URL and Keys. Configure the settings as needed to start using doc intel for extracting data from the PDF documents. We can stay within the Azure AI Foundry portal for most of these steps, but for more advanced configurations, we might need to use the Document Intelligence Studio. GitHub Copilot in VS Code for Azure Functions For processing portions of the output from Doc Intel, what better way to create the Azure Function than in VS Code, especially with the help of GitHub Copilot. Let’s start by installing the Azure Functions extension in VS Code, then create a new function project. GitHub Copilot can assist in writing the code to process the JSON received. Additionally, we can get Copilot to help generate unit tests to ensure the function works correctly. We could use Copilot to explain the code and the tests it generates. Finally, we seamlessly integrate the generated code and unit tests into the Functions app code file, all within VS Code. Notice how we can prompt GitHub Copilot from step 1 of Creating the Workspace to inserting the generated code into the Python file for the Azure Function to testing it and all the way to deploying the Function. Store and Analyze information in Fabric There are many options for storing and analyzing JSON data in Fabric. Lakehouse, Data Warehouse, SQL Database, Power BI Datamart. As our dataset is small, let’s choose either SQL DB or PBI Datamart. PBI Datamart is great for smaller datasets and direct integration with PBI for dashboarding while SQL DB is good for moderate data volumes and supports transactional & analytical workloads. To insert the JSON values derived in the Azure Functions App either called from Logic Apps or directly from the AI Foundry through the API calls into Fabric, let’s explore two approaches. Using REST API and the other Using Functions with Azure SQL DB. Using REST API – Fabric provides APIs that we can call directly from our Function to insert records using HTTP client in the Function’s Python code to send POST requests to the Fabric API endpoints with our JSON data. Using Functions with Azure SQL DB – we can connect it directly from our Function using the SQL client in the Function to execute SQL INSERT statements to add records to the database. While we are at it, we could even get GitHub Copilot to write up the Unit Tests. Here’s a sample: Visualization in Fabric Power BI Let's start with creating visualizations in Fabric using the web version of Power BI for our report, UtilitiesBillAnalysisDashboard. You could use the PBI Desktop version too. Open the PBI Service and navigate to the workspace where you want to create your report. Click on "New" and select "Dataset" to add a new data source. Choose "SQL Server" from the list of data sources and enter "UtilityBillsServer" as the server name and "UtilityBillsDB" as the DB name to establish the connection. Once connected, navigate to the Navigator pane where we can select the table "tblElectricity" and the columns. I’ve shown these in the pictures below. For a clustered column (or bar) chart, let us choose the columns that contain our categorical data (e.g., month, year) and numerical data (e.g., kWh usage, billed amounts). After loading the data into PBI, drag the desired fields into the Values and Axis areas of the clustered column chart visualization. Customize the chart by adjusting the formatting options to enhance readability and insights. We now visualize our data in PBI within Fabric. We may need to do custom sort of the Month column. Let’s do this in the Data view. Select the table and create a new column with the following formula. This will create a custom sort column that we will use as ‘Sum of MonthNumber’ in ascending order. Other visualizations possibilities: Other Possibilities Agents with Custom Copilot Studio Next, you could leverage a custom Copilot to provide personalized energy usage recommendations based on historical data. Start by integrating the Copilot with your existing data pipeline in Azure AI Foundry. The Copilot can analyze electricity consumption patterns stored in your Fabric SQL DB and use ML models to identify optimization opportunities. For instance, it could suggest energy-efficient appliances, optimal usage times, or tips to reduce consumption. These recommendations can be visualized in PBI where users can track progress over time. To implement this, you would need to set up an API endpoint for the Copilot to access the data, train the ML models using Python in VS Code (let GitHub Copilot help you here… you will love it), and deploy the models to Azure using CLI / PowerShell / Bicep / Terraform / ARM or the Azure portal. Finally, connect the Copilot to PBI to visualize the personalized recommendations. Additionally, you could explore using Azure AI Agents for automated anomaly detection and alerts. This agent could monitor electricity bill data for unusual patterns and send notifications when anomalies are detected. Yet another idea would be to implement predictive maintenance for electrical systems, where an AI agent uses predictive analytics to forecast maintenance needs based on the data collected, helping to reduce downtime and improve system reliability. Summary We have built a solution that leveraged the seamless integration of pioneering AI technologies with Microsoft’s end-to-end platform. By leveraging Azure AI Foundry, we have developed a solution that uses Document Intelligence to scan electricity bills, stores the data in Fabric SQL DB, and processes it with Python in Azure Functions in VS Code, assisted by GitHub Copilot. The resulting insights are visualized in Power BI within Fabric. Additionally, we explored potential enhancements using Azure AI Agents and Custom Copilots, showcasing the ease of implementation and the transformative possibilities. Finally, speaking of possibilities – With Gen AI, the only limit is our imagination!
