Ready to transform how your city plans and operates? Download the Trend Report 2025: Planning and operating thriving cities – innovation for smarter urban living to access the complete playbook on AI-powered urban innovation, complete with case studies from Bangkok, Singapore, Barcelona, and Manchester. Urban challenges aren’t slowing down. Populations are growing, climate pressures are intensifying, and residents expect seamless services, while budgets remain flat and workforces stretch thin. Traditional approaches can’t keep pace. The good news? Cities worldwide are showing that AI and digital innovation can drive meaningful improvements. Recent studies indicate that more than half of surveyed cities are already using AI to upgrade operations, and most plan to expand adoption in the next three years. For many leaders, the question is less about whether to act and more about how to act responsibly and effectively. After studying the latest research and real-world deployments, three strategic shifts stand out, each offering a different lens on how forward-thinking city leaders are turning pressure into progress. Shift One: From Fragmented services to unified citizen experiences Residents expect seamless problem-solving, not organizational complexity. Yet many cities operate in silos, transit systems, permitting offices, 311 reporting, and community engagement often run on separate platforms. The result? Multiple apps for residents, duplicated effort for staff, and missed insights locked in departmental databases. Leading cities are breaking this pattern through unified digital platforms powered by AI. Bangkok’s Traffy Fondue: Citizens report issues like broken streetlights or flooding via a mobile interface. AI categorizes each report and routes it to the right department. By mid-2025, the platform handled nearly one million citizen reports, improving engagement and reducing administrative overhead. The outcome? Reduced administrative overhead, and something harder to measure but equally important: residents who believe their government actually listens. Buenos Aires took a similar path with "Boti," a WhatsApp chatbot that evolved from a COVID-era tool into a citywide digital assistant. Citizens report issues, ask questions, and access services through the messaging app they already use daily. Technology that meets residents where they are improves efficiency and strengthens trust, when guided by principles of transparency and fairness. Shift Two: From reactive planning to predictive foresight Traditional urban planning relies on static models: masterplans, zoning maps, historical growth trends. These tools served their purpose. But they cannot capture the complexity of future risks, extreme weather, evolving mobility patterns, or the cascading effects of a single development decision. Digital twins complement human expertise by integrating geospatial data, climate models, and policy scenarios, helping cities make smarter decisions with limited budgets. Singapore's Digital Urban Climate Twin integrates geospatial data with climate models to simulate how different policies would affect temperature and thermal comfort across neighborhoods. These tools support informed decision-making while maintaining human oversight and accountability. The result? Strategic adaptation rather than reactive firefighting. Sydney built an urban digital twin that correlates environmental conditions with traffic accidents, using machine learning to predict crash risk on specific road segments. City planners can now test interventions virtually, what happens if we lower speed limits here? Add a bike lane there? Before committing resources. Even smaller cities are finding value. Imola, Italy uses a microclimate digital twin to model heat distribution street by street, guiding decisions about where to plant trees or specify cool pavement materials. The paradigm shift is profound: instead of planning based on what happened, cities can now plan based on what's likely to happen. This is how you make smart bets with limited budgets. Shift Three: From tech adoption to governance architecture Here's where many cities stumble. They invest in flashy pilots without building the institutional structures to sustain them. The cities getting this right treat governance as a strategic asset, not a compliance burden. Singapore's Model AI Governance Framework provides practical guidelines for transparency, fairness, and human-centric design. Its AI Verify toolkit lets organizations test their systems for resilience, accountability, and bias before deployment. Barcelona takes a different but equally rigorous approach, treating municipal data as a public asset under its Data Commons program. The city's procurement strategy favors open-source solutions, preventing vendor lock-in while supporting local innovation ecosystems. Both models share a common insight: rapid innovation doesn't automatically produce equitable outcomes. Governance creates the guardrails that allow experimentation without derailment. For city leaders, this means building cross-sector governance councils, adopting clear data strategies, creating ethical AI frameworks, and investing in workforce capability. These aren't obstacles to innovation; they're the foundation that makes sustained innovation possible. The Path Forward Cities that thrive in combine strategic vision with disciplined, responsible technology use. They embed digital capabilities into decision-making, supported by robust policies and cross-department collaboration.

Proactive Monitoring Made Simple with Azure SRE Agent
SRE teams strive for proactive operations, catching issues before they impact customers and reducing the chaos of incident response. While perfection may be elusive, the real goal is minimizing outages and gaining immediate line of sight into production environments. Today, that’s harder than ever. It requires correlating countless signals and alerts, understanding how they relate—or don’t relate—to each other, and assigning the right sense of urgency and impact. Anything that shortens this cycle, accelerates detection, and enables automated remediation is what modern SRE teams crave. What if you could skip the scripting and pipelines? What if you could simply describe what you want in plain language and let it run automatically on a schedule? Scheduled Tasks for Azure SRE Agent With Scheduled Tasks for Azure SRE Agent, that what-if scenario is now a reality. Scheduled tasks combine natural language prompts with Azure SRE Agent’s automation capabilities, so you can express intent, set a schedule, and let the agent do the rest—without writing a single line of code. This means: ⚡ Faster incident response through early detection ✅ Better compliance with automated checks 🎯 More time for high-value engineering work and innovation 💡 The shift from reactive to proactive: Instead of waiting for alerts to fire or customers to report issues, you’re continuously monitoring, validating, and catching problems before they escalate. How Scheduled Tasks Work Under the Hood When you create a Scheduled Task, the process is more than just running a prompt on a timer. Here’s what happens: 1. Prompt Interpretation and Plan Creation The SRE Agent takes your natural language prompt—such as “Scan all resources for security best practices”—and converts it into a structured execution plan. This plan defines the steps, tools, and data sources required to fulfill your request. 2. Built-In Tools and MCP Integration The agent uses its built-in capabilities (Azure CLI, Log Analytics workspace, Appinsights) and can also leverage 3 rd party data sources or tools via MCP server integration for extended functionality. 3. Results Analysis and Smart Summarization After execution, the agent analyzes results, identifies anomalies or issues, and provides actionable summaries not just raw data dumps. 4. Notification and Escalation Based on findings, the agent can: Post updates to Teams channels Create or update incidents Send email notifications Trigger follow-up actions Real-World Use Cases for Proactive Ops Here’s where scheduled tasks shine for SRE teams: Use Case Prompt Example Schedule Security Posture Check “Scan all subscriptions for resources with public endpoints and flag any that shouldn’t be exposed” Daily Cost Anomaly Detection “Compare this week’s spend against last week and alert if any service exceeds 20% growth” Weekly Compliance Drift Detection “Check all storage accounts for encryption settings and report any non-compliant resources” Daily Resource Health Summary “Summarize the health status of all production VMs and highlight any degraded instances” Every 4 hours Incident Trend Analysis “Analyze ICM incidents from the past week, identify patterns, and summarize top contributing services” Weekly Getting Started in 3 Steps Step 1: Define Your Intent Write a natural language prompt describing what you want to monitor or check. Be specific about: - What resources or scope - What conditions to look for - What action to take if issues are found Example: > “Every morning at 8 AM, check all production Kubernetes clusters for pods in CrashLoopBackOff state. If any are found, post a summary to the #sre-alerts Teams channel with cluster name, namespace, and pod details.” Step 2: Set Your Schedule Choose how often the task should run: - Cron expressions for precise control - Simple intervals (hourly, daily, weekly) Step 3: Define Where to Receive Updates Include in your prompt where you want results delivered when the task finishes execution. The agent can use its built-in tools and connectors to: - Post summaries to a Teams channel - Send email notifications - Create or update ICM incidents Example prompt with notification: > "Check all production databases for long-running queries over 30 seconds. If any are found, post a summary to the #database-alerts Teams channel." Why This Matters for Proactive Operations Traditional monitoring approaches have limitations: Traditional Approach With Scheduled Tasks Write scripts, maintain pipelines Describe in plain language Static thresholds and rules Contextual, AI-powered analysis Alert fatigue from noisy signals Smart summarization of what matters Separate tools for check vs. action Unified detection and response Requires dedicated DevOps effort Any SRE can create and modify The result? Your team spends less time building and maintaining monitoring infrastructure and more time on the work that truly requires human expertise. Best Practices for Scheduled Tasks Start simple, iterate — Begin with one or two high-value checks and expand as you gain confidence Be specific in prompts — The more context you provide, the better the results Set appropriate frequencies — Not everything needs to run hourly; match the schedule to the risk Review and refine — Check task results periodically and adjust prompts for better accuracy What’s Next? Scheduled tasks are just the beginning. We’re continuing to invest in capabilities that help SRE teams shift left—catching issues earlier, automating routine checks, and freeing up time for strategic work. Ready to Start?

TOC Introduction Local Environment Deployment Conclusion 1. Introduction Anthropic, the company behind Claude, recently acquired the JavaScript runtime startup Bun, marking one of the most significant shifts in the modern JavaScript ecosystem since the arrival of Node.js and Deno. This acquisition signals more than a business move, it represents a strategic consolidation of performance-oriented tooling, developer ergonomics, and the future of AI-accelerated software development. At the center of this momentum lies a powerful trio: Bun, Hono, and Vite. Bun is a next-generation JavaScript runtime that reimagines everything from dependency installation to HTTP servers, bundling, and execution speed. On top of Bun, frameworks like Hono provide an elegant, lightweight approach to building APIs and full web applications. Hono embraces the Web Standard API model while optimizing for speed and minimal footprint. For front-end development, Vite completes the trio. Vite provides lightning-fast local development through native ES modules and an optimized build pipeline. When paired with Bun, the developer experience becomes even smoother, as Bun accelerates not only the dev server but also the entire build process. The result is a full-stack workflow where front-end and back-end both benefit from a consistent, high-performance environment. This article will guide you through deploying a Bun + Hono + Vite application to an Azure Linux Web App. 2. Local Environment The development environment used in this example is a Docker container. All project creation, modification, and testing will take place inside this environment. We will build an application using Bun + Hono + Vite, containing three endpoints: / : The root endpoint, which displays Hello Bun Hono Vite /api/hello : A static endpoint /api/backend : A runtime endpoint executed on the server, returning computed results for the frontend to display Create the Docker development environment This command generates a Bun + Hono + Vite project. docker run --rm -it -v "$PWD":/app -w /app oven/bun:latest bunx create-vite . --template vanilla-ts Follow the prompts as shown in the image and make the appropriate selections. After completing the prompts, the corresponding project files will be created. At this point, you may press Ctrl + C to stop the running Bun server. Next, install Hono: docker run --rm -it -v "$PWD":/app -w /app oven/bun:latest bun add hono Create 4 files and edit 2 files Create .vscode/settings.json This file serves two purposes: To prevent the large node_modules folder from being uploaded during deployment. Uploading it wastes bandwidth and may cause compatibility issues between local and production environments. To disable ORYX BUILD from interfering in the deployment process. We will use a custom startup script to handle all build tasks instead. { "appService.zipIgnorePattern": [ "node_modules{,/**}", ".git{,/**}", ".vscode{,/**}" ], "appService.showBuildDuringDeployPrompt": false } Create vite.config.ts This file configures Vite’s base path to use relative paths instead of absolute paths. Although this does not affect the production environment, it is essential locally when URLs and ports may differ. import { defineConfig } from 'vite'; export default defineConfig({ base: './', }); Create server.ts This file configures backend routing using Hono and sets up the Bun server. It includes several test endpoints, some static, and some executed at runtime. import { Hono } from 'hono'; import { serveStatic } from 'hono/bun'; const app = new Hono(); app.get('/api/hello', (c) => { return c.text('this is api/hello'); }); app.get('/api/backend', (c) => { const result = 1 + 1; return c.json({ message: "this is /api/backend", calc: `1 + 1 = ${result}`, value: result, }); }); app.use('/assets/*', serveStatic({ root: './dist' })); app.use('/*', serveStatic({ root: './dist' })); app.get('/', serveStatic({ path: './dist/index.html' })); const port = Number(process.env.PORT ?? 3000); export default { port, fetch: app.fetch, }; Create startup.sh This script serves several important roles: Remove any node_modules folders or tar archives created by ORYX during deployment Install the Bun runtime Fully take over the ORYX build process Start the Bun server as the final step #!/bin/bash set -e echo "===== Startup script running =====" cd /home/site/wwwroot echo "Cleaning up Oryx-generated node_modules..." if [ -d /node_modules ]; then echo "Removing /node_modules ..." rm -rf /node_modules fi if [ -f node_modules.tar.gz ]; then echo "Removing node_modules.tar.gz ..." rm -f node_modules.tar.gz fi echo "Oryx cleanup complete." export BUN_INSTALL=/home/site/wwwroot/.bun export PATH="$BUN_INSTALL/bin:/home/site/wwwroot/node_modules/.bin:$PATH" export NODE_PATH="/home/site/wwwroot/node_modules" if [ ! -f "$BUN_INSTALL/bin/bun" ]; then echo "Bun not found. Installing..." curl -fsSL https://bun.sh/install | bash else echo "Bun already installed at $BUN_INSTALL" fi echo "Using Bun version:" bun --version echo "Running bun install ..." bun install echo "Running bun run build ..." bun run build echo "Starting server with bun run start ..." bun run start Modify src/main.ts Simplify the default welcome page so it only displays our test text. // src/main.ts document.querySelector<HTMLDivElement>('#app')!.innerHTML = ` <h1>Hello Bun Hono Vite</h1> `; Modify package.json Update the scripts section so that the project uses the newly created server.ts as the server entry point. { "name": "app", "private": true, "version": "0.0.0", "type": "module", "scripts": { "dev:vite": "vite", "build": "vite build", "preview": "vite preview", "start": "bun server.ts" }, "devDependencies": { "typescript": "~5.9.3", "vite": "^7.2.4" }, "dependencies": { "hono": "^4.10.7" } } Build the project locally This command generates a dist directory containing all Vite-built static assets. docker run --rm -it -v "$PWD":/app -w /app oven/bun:latest bun run build Run the server locally for testing docker run --rm -it -v "$PWD":/app -w /app -p 3000:3000 -e PORT=3000 oven/bun:latest bun run start You can press Ctrl + C to stop the server when finished. http://127.0.0.1:3000/ http://127.0.0.1:3000/api/hello http://127.0.0.1:3000/api/backend 3. Deployment We create a Linux Web App with a minimum SKU of Premium. Add Environment Variables SCM_DO_BUILD_DURING_DEPLOYMENT=false Purpose: Prevents the deployment environment from packaging during publish. This must also be set in the deployment environment itself. WEBSITE_RUN_FROM_PACKAGE=false Purpose: Instructs Azure Web App not to run the app from a prepackaged file. ENABLE_ORYX_BUILD=false Purpose: Prevents Azure Web App from building after deployment. All build tasks will instead execute during the startup script. Add Startup Command bash /home/site/wwwroot/startup.sh After that, we can return to VS Code and deploy the project. Once the deployment is complete, wait about five minutes for the build process to finish, and then you can begin testing. / /api/hello /api/backend 4. Conclusion Bun + Hono + Vite form a cohesive ecosystem that embodies the next era of JavaScript development: fast, compact, ergonomic, and deeply aligned with modern infrastructure needs. It is particularly well-suited for AI applications, where latency, concurrency, and rapid iteration matter more than ever. From streaming inference endpoints to vector database integrations, this stack offers the responsiveness and scalability essential for AI-powered systems.Common Misconceptions When Running Locally vs. Deploying to Azure Linux-based Web Apps
TOC Introduction Environment Variable Build Time Compatible Memory Conclusion 1. Introduction One of the most common issues during project development is the scenario where “the application runs perfectly in the local environment but fails after being deployed to Azure.” In most cases, deployment logs will clearly reveal the problem and allow you to fix it quickly. However, there are also more complicated situations where "due to the nature of the error itself" relevant logs may be difficult to locate. This article introduces several common categories of such problems and explains how to troubleshoot them. We will demonstrate them using Python and popular AI-related packages, as these tend to exhibit compatibility-related behavior. Before you begin, it is recommended that you read Deployment and Build from Azure Linux based Web App | Microsoft Community Hub on how Azure Linux-based Web Apps perform deployments so you have a basic understanding of the build process. 2. Environment Variable Simulating a Local Flask + sklearn Project First, let’s simulate a minimal Flask + sklearn project in any local environment (VS Code in this example). For simplicity, the sample code does not actually use any sklearn functions; it only displays plain text. app.py from flask import Flask app = Flask(__name__) @app.route("/") def index(): return "hello deploy environment variable" if __name__ == "__main__": app.run(host="0.0.0.0", port=8000) We also preset the environment variables required during Azure deployment, although these will not be used when running locally. .deployment [config] SCM_DO_BUILD_DURING_DEPLOYMENT=false As you may know, the old package name sklearn has long been deprecated in favor of scikit-learn. However, for the purpose of simulating a compatibility error, we will intentionally specify the outdated package name. requirements.txt Flask==3.1.0 gunicorn==23.0.0 sklearn After running the project locally, you can open a browser and navigate to the target URL to verify the result. python3 -m venv .venv source .venv/bin/activate pip install -r requirements.txt python app.py Of course, you may encounter the same compatibility issue even in your local environment. Simply running the following command resolves it: export SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True We will revisit this error and its solution shortly. For now, create a Linux Web App running Python 3.12 and configure the following environment variables. We will define Oryx Build as the deployment method. SCM_DO_BUILD_DURING_DEPLOYMENT=false WEBSITE_RUN_FROM_PACKAGE=false ENABLE_ORYX_BUILD=true After deploying the code and checking the Deployment Center, you should see an error similar to the following. From the detailed error message, the cause is clear: sklearn is deprecated and replaced by scikit-learn, so additional compatibility handling is now required by the Python runtime. The error message suggests the following solutions: Install the newer scikit-learn package directly. If your project is deeply coupled to the old sklearn package and cannot be refactored yet, enable compatibility by setting an environment variable to allow installation of the deprecated package. Typically, this type of “works locally but fails on Azure” behavior happens because the deprecated package was installed in the local environment a long time ago at the start of the project, and everything has been running smoothly since. Package compatibility issues like this are very common across various languages on Linux. When a project becomes tightly coupled to an outdated package, you may not be able to upgrade it immediately. In these cases, compatibility workarounds are often the only practical short-term solution. In our example, we will add the environment variable: SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True However, here comes the real problem: This variable is needed during the build phase, but the environment variables set in Azure Portal’s Application Settings only take effect at runtime. So what should we do? The answer is simple, shift the Oryx Build process from build-time to runtime. First, open Azure Portal → Configuration and disable Oryx Build. ENABLE_ORYX_BUILD=false Next, modify the project by adding a startup script. run.sh #!/bin/bash export SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True python -m venv .venv source .venv/bin/activate pip install -r requirements.txt python app.py The startup script works just like the commands you run locally before executing the application. The difference is that you can inject the necessary compatibility environment variables before running pip install or starting the app. After that, return to Azure Portal and add the following Startup Command under Stack Settings. This ensures that your compatibility environment variables and build steps run before the runtime starts. bash run.sh Your overall project structure will now look like this. Once redeployed, everything should work correctly. 3. Build Time Build-Time Errors Caused by AI-Related Packages Many build-time failures are caused by AI-related packages, whose installation processes can be extremely time-consuming. You can investigate these issues by reviewing the deployment logs at the following maintenance URL: https://<YOUR_APP_NAME>.scm.azurewebsites.net/newui Compatible Let’s simulate a Flask + numpy project. The code is shown below. app.py from flask import Flask app = Flask(__name__) @app.route("/") def index(): return "hello deploy compatible" if __name__ == "__main__": app.run(host="0.0.0.0", port=8000) We reuse the same environment variables from the sklearn example. .deployment [config] SCM_DO_BUILD_DURING_DEPLOYMENT=false This time, we simulate the incompatibility between numpy==1.21.0 and Python 3.10. requirements.txt Flask==3.1.0 gunicorn==23.0.0 numpy==1.21.0 We will skip the local execution part and move directly to creating a Linux Web App running Python 3.10. Configure the same environment variables as before, and define the deployment method as runtime build. SCM_DO_BUILD_DURING_DEPLOYMENT=false WEBSITE_RUN_FROM_PACKAGE=false ENABLE_ORYX_BUILD=false After deployment, Deployment Center shows a successful publish. However, the actual website displays an error. At this point, you must check the deployment log files mentioned earlier. You will find two key logs: 1. docker.log Displays real-time logs of the platform creating and starting the container. In this case, you will see that the health probe exceeded the default 230-second startup window, causing container startup failure. This tells us the root cause is container startup timeout. To determine why it timed out, we must inspect the second file. 2. default_docker.log Contains the internal execution logs of the container. Not generated in real time, usually delayed around 15 minutes. Therefore, if docker.log shows a timeout error, wait at least 15 minutes to allow the logs to be written here. In this example, the internal log shows that numpy was being compiled during pip install, and the compilation step took too long. We now have a concrete diagnosis: numpy 1.21.0 is not compatible with Python 3.10, which forces pip to compile from source. The compilation exceeds the platform’s startup time limit (230 seconds) and causes the container to fail. We can verify this by checking numpy’s official site: numpy · PyPI numpy 1.21.0 only provides wheels for cp37, cp38, cp39 but not cp310 (which is python 3.10). Thus, compilation becomes unavoidable. Possible Solutions Set the environment variable WEBSITES_CONTAINER_START_TIME_LIMIT to increase the allowed container startup time. Downgrade Python to 3.9 or earlier. Upgrade numpy to 1.21.0+, where suitable wheels for Python 3.10 are available. In this example, we choose this option. After upgrading numpy to version 1.25.0 (which supports Python 3.10) from specifying in requirements.txt and redeploying, the issue is resolved. numpy · PyPI requirements.txt Flask==3.1.0 gunicorn==23.0.0 numpy==1.25.0 Memory The final example concerns the App Service SKU. AI packages such as Streamlit, PyTorch, and others require significant memory. Any one of these packages may cause the build process to fail due to insufficient memory. The error messages vary widely each time. If you repeatedly encounter unexplained build failures, check Deployment Center or default_docker.log for Exit Code 137, which indicates that the system ran out of memory during the build. The only solution in such cases is to scale up. 4. Conclusion This article introduced several common troubleshooting techniques for resolving Linux Web App issues caused during the build stage. Most of these problems relate to package compatibility, although the symptoms may vary greatly. By understanding the debugging process demonstrated in these examples, you will be better prepared to diagnose and resolve similar issues in future deployments.Microsoft Defender for Cloud Customer Newsletter
