How to Ensure Seamless Data Recovery and Deployment in Microsoft Azure
Overcoming Cosmos DB Backup and Restore Challenges with Azure Databricks The Challenge of Backing Up and Restoring Azure Cosmos DB One of the significant pain points when working with Azure Cosmos DB is the lack of instant, self-service backup restoration. While Cosmos DB is engineered for global scalability and high availability, its backup and recovery process introduces a crucial bottleneck for organizations that demand agility. Backups in Cosmos DB are created automatically, but restoring them isn’t a seamless, on-demand operation. Instead, it often involves lengthy procedures and sometimes requires intervention from Microsoft support, causing delays that can stretch from hours to even longer—depending on the size and complexity of your data. Downtime Risks: During the drawn-out restore process, your applications might face downtime or reduced performance, impacting end-users and business operations. Deployment Delays: The inability to rapidly roll back or restore data can turn even minor deployment hiccups into major headaches. Lack of Flexibility: Developers and DevOps teams miss the control of instant, self-service restores, limiting their ability to efficiently manage data recovery. Compliance Hurdles: Industries with strict regulatory requirements may struggle to meet recovery time objectives due to slow data restoration. Why Instant Restore Capabilities Matter As cloud-native environments thrive on speed and reliability, the ability to restore data instantly is more than a convenience—it’s essential for: Rapid recovery from accidental data loss or corruption. Enabling safe, confident deployments with a reliable rollback plan. Supporting dynamic test and staging environments using current data snapshots. Without instant restore, organizations face heightened risks and operational slowdowns, which can stifle innovation and erode customer trust. How Azure Databricks Offers a Solution Azure Databricks steps in as a powerful ally for teams looking to bypass these backup limitations. Combining the flexibility of Apache Spark with seamless Azure integration, Databricks allows you to automate data exports, transformations, and—most importantly—restoration workflows customized to your exact needs. Restoring Data Before Deployment: A Practical Approach Automated, Periodic Backups: Databricks notebooks can regularly export Cosmos DB collections into Azure Data Lake or Blob Storage, providing you with up-to-date data snapshots. On-Demand Restoration: When it’s time to deploy or test, Databricks can efficiently restore backup data into a separate Cosmos DB container, preserving production data and minimizing risk. Deployment Safety Net: With a fresh container ready, teams can proceed with confidence, knowing that any deployment misstep can be instantly rolled back—no more waiting for time-consuming support escalations. Seamless Automation: Databricks workflows can be integrated with CI/CD pipelines, customized for various environments, and scheduled or triggered as needed. A Sample Workflow Set up Databricks to regularly back up Cosmos DB data to Azure storage. Before deployment, launch a Databricks job to restore the latest backup into a separate Cosmos DB container. Test and verify the deployment using the restored container, ensuring maximum safety and the ability to roll back instantly if needed. Once deployment is confirmed, switch over or merge as appropriate, with minimal risk to production data. The Benefits at a Glance Minimal Downtime: Quick restoration helps avoid business disruptions during incidents or rollbacks. Operational Agility: Teams can move faster, knowing that data can be restored whenever needed. Enhanced Data Protection: Using separate containers ensures production data remains shielded from accidental changes. Efficiency Gains: Automated processes reduce manual workload and the need for direct intervention. Conclusion Azure Cosmos DB’s backup and restore limitations present real challenges for organizations seeking agility and reliability.

Why this article? To remove the vulnerability of exposing the data base connection string in Databricks notebook directly, by using Azure key vault. Database connection strings are extremely confidential/vulnerable data, that we should not be exposed in the DataBricks notebook explicitly. Azure key vault is a secure option to read the secrets and establish connection. What do we need? Tenant Id of the app from the app registration with access to the azure key vault secrets Client Id of the of the app from the app registration with access to the azure key vault secrets Client secret of the app from the app registration with access to the azure key vault Where to find this information? Under the App registration, you can find the (application) Client Id, Directory (tenant) Id. Client secret value is found in the app registration of the service, under Manage -> Certificate & secrets. You can use an existing secret or create a new one and use it to access the key Vault secrets. Make sure the application is added with get access to read the secrets. Verify the key vault you are checking and using in Databricks is the same one with read access. You can verify this by going to the Azure key vault -> Access Policies and search for the application name. It should show up on search as below, this will confirm that the access of the application. What do we need to setup in Databricks notebook? Open your cluster and install azure.keyvault and azure-identity (installing version should be compatible with you cluster configuration, refer: https://docs.databricks.com/aws/en/libraries/package-repositories) In a new notebook, let’s start by importing the necessary modules. Your notebook would start with the modules, followed by tentatId, clientId, client secret, azure key vault URL , secretName of the connection string in the azure key vault and secretVersion. Lastly, we need to fetch the secret using the below code Vola, we have the DB connection string to perform the CRUD operations. Conclusion: By securely retrieving your database connection string from Azure Key Vault, you eliminate credential exposure and strengthen the overall security posture of your Databricks workflows. This simple shift ensures your notebooks remain clean, compliant, and production‑ready.Learn how to build MCP servers with Python and Azure

From “waiting” to “instant”- without sending data away AI is everywhere, but speed, privacy, and reliability are critical. Users expect instant answers without compromise. On-device AI makes that possible: fast, private and available, even when the network isn’t - empowering apps to deliver seamless experiences. Imagine an intelligent assistant that works in seconds, without sending a text to the cloud. This approach brings speed and data control to the places that need it most; while still letting you tap into cloud power when it makes sense. Windows AI Foundry: A Local Home for Models Windows AI Foundry is a developer toolkit that makes it simple to run AI models directly on Windows devices. It uses ONNX Runtime under the hood and can leverage CPU, GPU (via DirectML), or NPU acceleration, without requiring you to manage those details. The principle is straightforward: Keep the model and the data on the same device. Inference becomes faster, and data stays local by default unless you explicitly choose to use the cloud. Foundry Local Foundry Local is the engine that powers this experience. Think of it as local AI runtime - fast, private, and easy to integrate into an app. Why Adopt On‑Device AI? Faster, more responsive apps: Local inference often reduces perceived latency and improves user experience. Privacy‑first by design: Keep sensitive data on the device; avoid cloud round trips unless the user opts in. Offline capability: An app can provide AI features even without a network connection. Cost control: Reduce cloud compute and data costs for common, high‑volume tasks. This approach is especially useful in regulated industries, field‑work tools, and any app where users expect quick, on‑device responses. Hybrid Pattern for Real Apps On-device AI doesn’t replace the cloud, it complements it. Here’s how: Standalone On‑Device: Quick, private actions like document summarization, local search, and offline assistants. Cloud‑Enhanced (Optional): Large-context models, up-to-date knowledge, or heavy multimodal workloads. Design an app to keep data local by default and surface cloud options transparently with user consent and clear disclosures. Windows AI Foundry supports hybrid workflows: Use Foundry Local for real-time inference. Sync with Azure AI services for model updates, telemetry, and advanced analytics. Implement fallback strategies for resource-intensive scenarios. Application Workflow Code Example using Foundry Local: 1. Only On-Device: Tries Foundry Local first, falls back to ONNX if foundry_runtime.check_foundry_available(): # Use on-device Foundry Local models try: answer = foundry_runtime.run_inference(question, context) return answer, source="Foundry Local (On-Device)" except Exception as e: logger.warning(f"Foundry failed: {e}, trying ONNX...") if onnx_model.is_loaded(): # Fallback to local BERT ONNX model try: answer = bert_model.get_answer(question, context) return answer, source="BERT ONNX (On-Device)" except Exception as e: logger.warning(f"ONNX failed: {e}") return "Error: No local AI available" 2. Hybrid approach: On-device first, cloud as last resort def get_answer(question, context): """ Priority order: 1. Foundry Local (best: advanced + private) 2. ONNX Runtime (good: fast + private) 3. Cloud API (fallback: requires internet, less private) # in case of Hybrid approach, based on real-time scenario """ if foundry_runtime.check_foundry_available(): # Use on-device Foundry Local models try: answer = foundry_runtime.run_inference(question, context) return answer, source="Foundry Local (On-Device)" except Exception as e: logger.warning(f"Foundry failed: {e}, trying ONNX...") if onnx_model.is_loaded(): # Fallback to local BERT ONNX model try: answer = bert_model.get_answer(question, context) return answer, source="BERT ONNX (On-Device)" except Exception as e: logger.warning(f"ONNX failed: {e}, trying cloud...") # Last resort: Cloud API (requires internet) if network_available(): try: import requests response = requests.post( '{BASE_URL_AI_CHAT_COMPLETION}', headers={'Authorization': f'Bearer {API_KEY}'}, json={ 'model': '{MODEL_NAME}', 'messages': [{ 'role': 'user', 'content': f'Context: {context}\n\nQuestion: {question}' }] }, timeout=10 ) answer = response.json()['choices'][0]['message']['content'] return answer, source="Cloud API (Online)" except Exception as e: return "Error: No AI runtime available", source="Failed" else: return "Error: No internet and no local AI available", source="Offline" Demo Project Output: Foundry Local answering context-based questions offline : The Foundry Local engine ran the Phi-4-mini model offline and retrieved context-based data. : The Foundry Local engine ran the Phi-4-mini model offline and mentioned that there is no answer. Practical Use Cases Privacy-First Reading Assistant: Summarize documents locally without sending text to the cloud. Healthcare Apps: Analyze medical data on-device for compliance. Financial Tools: Risk scoring without exposing sensitive financial data. IoT & Edge Devices: Real-time anomaly detection without network dependency. Conclusion On-device AI isn’t just a trend - it’s a shift toward smarter, faster, and more secure applications. With Windows AI Foundry and Foundry Local, developers can deliver experiences that respect user specific data, reduce latency, and work even when connectivity fails. By combining local inference with optional cloud enhancements, you get the best of both worlds: instant performance and scalable intelligence. Whether you’re creating document summarizers, offline assistants, or compliance-ready solutions, this approach ensures your apps stay responsive, reliable, and user-centric.

Over the past several months, I’ve spent hundreds of hours working directly with teams—from small startups to mid-market innovators—who share the same aspiration: “We want to use AI, but where do we start?” This question comes up everywhere. It crosses industries, geographies, skill levels, and team sizes. And as developers, we often feel the pressure to “solve AI” end-to-end—model selection, prompt engineering, security, deployment pipelines, integration…. The list is long, and the learning curve can feel even longer. But here’s what we’ve learned through our work in the SMB space and what we recently shared at Microsoft Ignite (Session OD1210). The first mile of AI doesn’t have to be complex. You don’t need an army of engineers, and you don’t need to start from scratch. You just need the right path. In our Ignite on-demand session with UnifyCloud, we demonstrated two fast, developer-friendly ways to get your first AI workload running on Azure—both grounded in real-world patterns we see every day. Path 1: Build Quickly with Microsoft Foundry Templates Microsoft Foundry gives developers pre-built, customizable templates that dramatically reduce setup time. In the session, I walked through how to deploy a fully functioning AI chatbot using: Azure AI Foundry GitHub (via the Azure Samples “Get Started with AI Chat” repo) Azure Cloudshell for deployment And zero specialized infra prep With five lines of code and a few clicks, you can spin up a secure internal chatbot tailored for your business. Want responses scoped to your internal content? Want control over the model, costs, or safety filters? Want to plug in your own data sources like SharePoint, Blob Storage, or uploaded docs? You can do all of that—easily and on your terms. This “build fast” path is ideal for: Developers who want control and extensibility Teams validating AI use cases Scenarios where data governance matters Lightweight experimentation without heavy architecture upfront And most importantly, you can scale it later. Path 2: Buy a Production-Ready Solution from a Trusted Partner Not every team wants to build. Not every team has the time, the resources, or the desire to compose their own AI stack. That’s why we showcased the “buy” path with UnifyCloud’s AI Factory, a Marketplace-listed solution that lets customers deploy mature AI capabilities directly into their Azure environment, complete with optional support, management, and best practices. In the demo, UnifyCloud’s founder Vivek Bhatnagar walked through: How to navigate Microsoft Marketplace How to evaluate solution listings How to review pricing plans and support tiers How to deploy a partner-built AI app with just a few clicks How customers can accelerate their time to value without implementation overhead This path is perfect when you want: A production-ready AI solution A supported, maintained experience Minimal engineering lift Faster time to outcome Why Azure? Why Now? During the session, we also outlined three reasons developers are choosing Azure for their first AI workloads: 1. Secure, governed, safe by design Azure mitigates risk with always-on guardrails and built-in commitments to security, privacy, and policy-based control. 2. Built for production with a complete AI platform From models to agents to tools and data integrations, Azure provides an enterprise-grade environment developers can trust. 3. Developer-first innovation with agentic DevOps Azure puts developers at the center, integrating AI across the software development lifecycle to help teams build faster and smarter. The Session: Build or Buy—Two Paths, One Goal Whether you build using Azure AI Foundry or buy through Marketplace, the goal is the same: Help teams get to their first AI solution quickly, confidently, and securely. You don’t need a massive budget. You don’t need deep ML experience. You don’t need a full-time AI team. What you need is a path that matches your skills, your constraints, and your timeline. Watch the Full Ignite Session You can watch the full session on-demand now also on YouTube: OD1201 — “Unlock Your First AI Solution on Azure” It includes: The full build and buy demos Partner perspectives Deployment walkthroughs And guidance you can take back to your teams today If you want to explore the same build path we showed at Ignite: ➡️ Azure Samples – Get Started with AI Chat https://github.com/Azure-Samples/get-started-with-ai-chat Deploy it, customize it, attach your data sources, and extend it. It’s a great starting point. If you’re curious about the Marketplace path: ➡️ Search for “UnifyCloud AI Factory” on Microsoft Marketplace You’ll see support offerings, solution details, and deployment instructions. Closing Thought The gap between wanting to adopt AI and actually running AI in production is shrinking fast. Azure makes it possible for teams, especially those without deep AI experience, to take meaningful steps today. No perfect architecture required. No million-dollar budget. No wait for a future-state roadmap. Just two practical paths: Build quickly. Buy confidently. Start now. If you have questions, ideas, or want to share what you’re building, feel free to reach out here in the Developer Community. I’d love to hear what you’re creating. — Joshua Huang Microsoft AzureBackground tasks in .NET
What is a Background Task? A background task (or background service) is work that runs behind the scenes in an application without blocking the main user flow and often without direct user interaction. Think of it as a worker or helper that performs tasks independently while the main app continues doing other things. Problem Statement - What do you do when your downstream API is flaky or sometimes down for hours or even days , yet your UI and main API must stay responsive? Solution - This is a very common architecture problem in enterprise systems, and .NET gives us excellent tools to solve it cleanly: BackgroundService and exponential backoff retry logic. In this article, I’ll walk you through: A real production-like use case The architecture needed to make it reliable Why exponential backoff matters How to build a robust BackgroundService A full working code example The Use Case You have two APIs: API 1 : called frequently by the UI (hundreds or thousands of times). API 2 : a downstream system you must call, but it is known to be unstable, slow, or completely offline for long periods. If API 1 directly calls API 2: * Users experience lag * API 1 becomes slow or unusable * You overload API 2 with retries * Calls fail when API 2 is offline * You lose data What do we do then? Here goes the solution The Architecture Instead of calling API 2 synchronously, API 1 simply stores the intended call, and returns immediately. A BackgroundService will later: Poll for pending jobs Call API 2 Retry with exponential backoff if API 2 is still unavailable Mark jobs as completed when successful This creates a resilient, smooth, non-blocking system. Why Exponential Backoff? When a downstream API is completely offline, retrying every 1–5 seconds is disastrous: It wastes CPU and bandwidth It floods logs It overloads API 2 when it comes back online It burns resources Exponential backoff solves this. Examples retry delays: Retry 1 → 2 sec Retry 2 → 4 sec Retry 3 → 8 sec Retry 4 → 16 sec Retry 5 → 32 sec Retry 6 → 64 sec (Max delay capped at 5 minutes) This gives the system room to breathe. Complete Working Example (Using In-Memory Store) 1. The Model public class PendingJob { public Guid Id { get; set; } = Guid.NewGuid(); public string Payload { get; set; } = string.Empty; public int RetryCount { get; set; } = 0; public DateTime NextRetryTime { get; set; } = DateTime.UtcNow; public bool Completed { get; set; } = false; } 2. The In-Memory Store public interface IPendingJobStore { Task AddJobAsync(string payload); Task<List<PendingJob>> GetExecutableJobsAsync(); Task MarkJobAsCompletedAsync(Guid jobId); Task UpdateJobAsync(PendingJob job); } public class InMemoryPendingJobStore : IPendingJobStore { private readonly List<PendingJob> _jobs = new(); private readonly object _lock = new(); public Task AddJobAsync(string payload) { lock (_lock) { _jobs.Add(new PendingJob { Payload = payload, RetryCount = 0, NextRetryTime = DateTime.UtcNow }); } return Task.CompletedTask; } public Task<List<PendingJob>> GetExecutableJobsAsync() { lock (_lock) { return Task.FromResult(_jobs.Where(j => !j.Completed && j.NextRetryTime <= DateTime.UtcNow).ToList()); } } public Task MarkJobAsCompletedAsync(Guid jobId) { lock (_lock) { var job = _jobs.FirstOrDefault(j => j.Id == jobId); if (job != null) job.Completed = true; } return Task.CompletedTask; } public Task UpdateJobAsync(PendingJob job) => Task.CompletedTask; } 3. The BackgroundService with Exponential Backoff using System.Text; public class Api2RetryService : BackgroundService { private readonly IHttpClientFactory _clientFactory; private readonly IPendingJobStore _store; private readonly ILogger<Api2RetryService> _logger; public Api2RetryService(IHttpClientFactory clientFactory, IPendingJobStore store, ILogger<Api2RetryService> logger) { _clientFactory = clientFactory; _store = store; _logger = logger; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { _logger.LogInformation("Background retry service started."); while (!stoppingToken.IsCancellationRequested) { var jobs = await _store.GetExecutableJobsAsync(); foreach (var job in jobs) { var client = _clientFactory.CreateClient("api2"); try { var response = await client.PostAsync("/simulate", new StringContent(job.Payload, Encoding.UTF8, "application/json"), stoppingToken); if (response.IsSuccessStatusCode) { _logger.LogInformation("Job {JobId} processed successfully.", job.Id); await _store.MarkJobAsCompletedAsync(job.Id); } else { await HandleFailure(job); } } catch (Exception ex) { _logger.LogError(ex, "Error calling API 2."); await HandleFailure(job); } } await Task.Delay(TimeSpan.FromSeconds(5), stoppingToken); } } private async Task HandleFailure(PendingJob job) { job.RetryCount++; var delay = CalculateBackoff(job.RetryCount); job.NextRetryTime = DateTime.UtcNow.Add(delay); await _store.UpdateJobAsync(job); _logger.LogWarning("Retrying job {JobId} in {Delay}. RetryCount={RetryCount}", job.Id, delay, job.RetryCount); } private TimeSpan CalculateBackoff(int retryCount) { var seconds = Math.Pow(2, retryCount); var maxSeconds = TimeSpan.FromMinutes(5).TotalSeconds; return TimeSpan.FromSeconds(Math.Min(seconds, maxSeconds)); } } 4. The API 1 — Public Endpoint using System.Runtime.InteropServices; using System.Text.Json; [ApiController] [Route("api1")] public class Api1Controller : ControllerBase { private readonly IPendingJobStore _store; private readonly ILogger<Api1Controller> _logger; public Api1Controller(IPendingJobStore store, ILogger<Api1Controller> logger) { _store = store; _logger = logger; } [HttpPost("process")] public async Task<IActionResult> Process([FromBody] object data) { var payload = JsonSerializer.Serialize(data); await _store.AddJobAsync(payload); _logger.LogInformation("Stored job for background processing."); return Ok("Request received. Will process when API 2 recovers."); } } 5. The API 2 (Simulating Downtime) using System.Runtime.InteropServices; [ApiController][Route("api2")] public class Api2Controller: ControllerBase { private static bool shouldFail = true; [HttpPost("simulate")] public IActionResult Simulate([FromBody] object payload) { if (shouldFail) return StatusCode(503, "API 2 is down"); return Ok("API 2 processed payload"); } [HttpPost("toggle")] public IActionResult Toggle() { shouldFail = !shouldFail; return Ok($"API 2 failure mode = {shouldFail}"); } } 6. The Program.cs var builder = WebApplication.CreateBuilder(args); builder.Services.AddControllers(); builder.Services.AddSingleton<IPendingJobStore, InMemoryPendingJobStore>(); builder.Services.AddHttpClient("api2", c => { c.BaseAddress = new Uri("http://localhost:5000/api2"); }); builder.Services.AddHostedService<Api2RetryService>(); var app = builder.Build(); app.MapControllers(); app.Run(); Testing the Whole Flow #1 API 2 starts in failure mode All attempts will fail and exponential backoff kicks in. #2 Send a request to API 1 POST /api1/process { "name": "hello" } Job is stored. #3 Watch logs You’ll see: Retrying job in 2 seconds... Retrying job in 4 seconds... Retrying job in 8 seconds... ... #4 Bring API 2 back online: POST /api2/toggle Next retry will succeed: Job {id} processed successfully.

What is Dapr? Dapr is an open-source runtime developed by Microsoft that is used in building resilient, event-driven, and portable applications. It works using the sidecar pattern, meaning every microservice gets a small companion container — the Dapr sidecar — which handles communication, retries, secrets, state, and more. What is Sidecar ? A sidecar is a helper process that runs beside your app, handling system tasks so your code can focus on business logic. Lets see some offerings from Dapr along with examples. #1 . Bindings Connects your app to external systems (like queues, email, or storage) with zero SDK or protocol handling. Without Dapr ❌ var httpClient = new HttpClient(); await httpClient.PostAsJsonAsync("https://api.sendgrid.com/send", email); * Manage HTTP endpoints & credentials * Change provider → rewrite logic With Dapr ✅ await daprClient.InvokeBindingAsync("send-email", "create", email); * One call, no SDK * Replace SendGrid → SMTP → Twilio just by editing config * No code change, no redeploy How to enable binding in for a Azure Container App Open Azure Portal → go to your Container App Environment. From the left pane, click on Container Apps, and choose your desired app (e.g., orders-api). In the Settings section, select Dapr. Enable Dapr toggle → switch it ON. Provide the basic Dapr settings: App ID: A unique name (e.g., orders-app). App Port: The internal port your API listens on (e.g., 8080). App Protocol: Choose HTTP or gRPC (usually HTTP). Click Save to apply. Now, under the same Container App Environment, go to Dapr Components. Click Create → select Binding → choose the type of binding (e.g., azure.storagequeues). #2 . Configuration Centralizes app settings, allowing live configuration updates without redeploying services. Without Dapr ❌ var featureFlag = Configuration["FeatureX"]; * Requires redeploys for every config change * No centralized versioning or dynamic update With Dapr ✅ var config = await daprClient.GetConfiguration("appconfigstore", new[] { "FeatureX" }); * Use Azure App Config, Consul, or any provider * Centralized updates — no redeploys * Consistent access via Dapr SDK How to enable configuration in for a Azure Container App Open Azure Portal → go to your Container App Environment. From the left pane, click on Container Apps, and choose your desired app (e.g., orders-api). In the Settings section, select Dapr. Enable Dapr toggle → switch it ON. Provide the basic Dapr settings: App ID: A unique name (e.g., orders-app). App Port: The internal port your API listens on (e.g., 8080). App Protocol: Choose HTTP or gRPC (usually HTTP). Click Save to apply. Now, under the same Container App Environment, go to Dapr Components. Click Create → select Configuration→ choose the type of configuration (e.g., configuration.azure.appconfig). #3 . Pub/Sub Enables event-driven communication between microservices without needing to know each other's endpoints. Without Dapr ❌ var client = new ServiceBusClient("<connection-string>"); var sender = client.CreateSender("order-topic"); await sender.SendMessageAsync(new ServiceBusMessage(orderJson)); * Tied to Azure Service Bus * Must manage SDKs, connections, retries * Hard to switch to another broker (Kafka, RabbitMQ) With Dapr ✅ await daprClient.PublishEventAsync("pubsub", "order-created", order); * pubsub component defined in YAML (can be Kafka, Redis Streams, etc.) * No SDK, no broker dependency * Just publish the event — Dapr handles transport & retries How to enable pub/sub in for a Azure Container App Open Azure Portal → go to your Container App Environment. From the left pane, click on Container Apps, and choose your desired app (e.g., orders-api). In the Settings section, select Dapr. Enable Dapr toggle → switch it ON. Provide the basic Dapr settings: App ID: A unique name (e.g., orders-app). App Port: The internal port your API listens on (e.g., 8080). App Protocol: Choose HTTP or gRPC (usually HTTP). Click Save to apply. Now, under the same Container App Environment, go to Dapr Components. Click Create → select Pub/Sub→ choose the type of configuration (e.g., pubsub.azure.servicebus.topics). #4 . Secret Stores Securely retrieves credentials and secrets from vaults, keeping them out of configs and code. Without Dapr ❌ var connString = Configuration["ConnectionStrings:DB"]; * Secrets stored in configs or env vars * Risk of leaks and manual rotation With Dapr ✅ var secret = await daprClient.GetSecretAsync("vault", "dbConnection"); * Fetch directly from Azure Key Vault, AWS Secrets, etc. * No secrets in configs * Secure by default, consistent across services How to enable Secret Stores in for a Azure Container App Open Azure Portal → go to your Container App Environment. From the left pane, click on Container Apps, and choose your desired app (e.g., orders-api). In the Settings section, select Dapr. Enable Dapr toggle → switch it ON. Provide the basic Dapr settings: App ID: A unique name (e.g., orders-app). App Port: The internal port your API listens on (e.g., 8080). App Protocol: Choose HTTP or gRPC (usually HTTP). Click Save to apply. Now, under the same Container App Environment, go to Dapr Components. Click Create → select Secret stores→ choose the type of configuration (e.g., secretstores.azure.keyvault). #5 . State Provides a consistent way to store and retrieve application data across services using a simple API. Without Dapr ❌ var cosmosClient = new CosmosClient(connStr); var container = cosmosClient.GetContainer("db", "state"); await container.UpsertItemAsync(order); * Direct dependency on Cosmos DB * Manual retry logic * Tight coupling to storage type With Dapr ✅ await daprClient.SaveStateAsync("statestore", "order-101", order); var data = await daprClient.GetStateAsync<Order>("statestore", "order-101"); * Plug any backend (Redis, Cosmos, PostgreSQL) * Dapr handles retries and consistency * Same code, different backend — total flexibility How to enable State in for a Azure Container App Open Azure Portal → go to your Container App Environment. From the left pane, click on Container Apps, and choose your desired app (e.g., orders-api). In the Settings section, select Dapr. Enable Dapr toggle → switch it ON. Provide the basic Dapr settings: App ID: A unique name (e.g., orders-app). App Port: The internal port your API listens on (e.g., 8080). App Protocol: Choose HTTP or gRPC (usually HTTP). Click Save to apply. Now, under the same Container App Environment, go to Dapr Components. Click Create → select State → choose the type of configuration (e.g., state.azure.cosmosdb). 🧩 Summary Think of Dapr as your invisible co-pilot for building distributed apps. It abstracts away all the repetitive plumbing — state management, pub/sub messaging, secret handling, and external bindings — letting you focus on writing features that matter. With Dapr, you don’t just write code that runs locally; you write code that just works across clouds, containers, and environments, without having to worry about wiring up retries, event delivery, or service-to-service communication manually. 🧰 Demo Source Code I've prepared complete sample on .Net core that touches all major Dapr features: * State Store * Pub/Sub * Bindings * Configuration * Secret Store You can explore it from Github-Dapr-Api Clone, run locally, and experiment — the project uses in-memory storage to keep things lightweight for testing and learning. 📚 References for Deep Dive Official Dapr Docs Dapr for .NET Developers — Microsoft Learn Dapr .NET SDK GitHubPython + IA: Resumen y Recursos
Acabamos de concluir nuestra serie sobre Python + IA, un recorrido completo de nueve sesiones donde exploramos a fondo cómo usar modelos de inteligencia artificial generativa desde Python. Durante la serie presentamos varios tipos de modelos, incluyendo LLMs, modelos de embeddings y modelos de visión. Profundizamos en técnicas populares como RAG, tool calling y salidas estructuradas. Evaluamos la calidad y seguridad de la IA mediante evaluaciones automatizadas y red-teaming. Finalmente, desarrollamos agentes de IA con frameworks populares de Python y exploramos el nuevo Model Context Protocol (MCP). Para que puedas aplicar lo aprendido, todos nuestros ejemplos funcionan con GitHub Models, un servicio que ofrece modelos gratuitos a todos los usuarios de GitHub para experimentación y aprendizaje.
