Get more CPU, memory, disk space, and extra features. This article includes information about how to increase limits along with maximum values. A web application ought to scale quite well in terms of concurrency because each request can be handled in parallel - but I am seeing that even with a low It is not per replica but for the entire Azure container app itself. I have a Consumption Plan, Overview Azure Functions integrates with Azure Service Bus via triggers and bindings, allowing you to build event-driven applications that react to queue and topic messages. Concurrency in Azure Functions In Azure Functions, a single function app instance allows for multiple events to be processed concurrently. When you host your functions in a Dedicated (App Service) plan, you must manually configure your instances or [set up an autoscale Conclusion To limit concurrency and control scaling in Azure Functions with queue triggers, you must limit your Azure Function to use one queue trigger per function app and use the Examples include Microsoft products and services such as Azure Monitor, and Playfab. Custom: Based on custom metrics like: CPU Memory Supported event-driven data sources: Azure Service Target-based scaling introduces faster scaling, and uses defaults for target executions per instance. md).

When using Service Bus, Storage queues, or Kafka, you can also enable dynamic The Azure Storage client libraries don't support concurrent writes to the same blob, with the exception of append blobs if the write order doesn't matter. In the portal, you can review quotas Become familiar with concurrency behavior of event-driven triggers in Azure Functions. You can specify the number of parallel python processes (workers) by having In May, dynamic concurrency(denoted as DC in this blog) in Azure Functions became generally available. To enable your Service Bus trigger to use Here is a test result (web app with S1 app service plan, 250 concurrent customers, URL point to a static html page) CPU and Memory usage How to deploy a Flex Consumption Function App using Terraform, including VNet integration, via the AzAPI provider — before native AzureRM support arrived. In addition to batching behaviors, you can manage concurrency for a number of triggers. Azure App Service provides built-in monitoring functionality for web, mobile, and API apps in the Azure portal. Learn about fundamental orchestration patterns for AI agent architectures, including sequential, concurrent, group chat, handoff, and magentic patterns. The Azure storage service supports all three strategies, although it is distinctive in its ability to provide full support for optimistic and pessimistic concurrency because it was designed to Hi There, in our environment we have a Function App (isolated dotnet 8) with 5 Service Bus Triggers. In What is the recommended way to limit an Azure Service bus trigger concurrent message processing when the Azure function is set to an App Service plan? I know one can do it using "Max Azure Monitor alerts have several throttling limits to protect against users making an excessive number of calls. 1 Hosted as Azure App Service I wish to restrict the total number of concurrent HTTP requests to the We will learn how to configure Gunicorn to efficiently handle multiple concurrent requests for a Flask App on Azure App Service Linux. How can I enable concurrent (parallel) HTTP requests for the Azure web service app?

My customer wants to run 1-2 M concurrent req on App Service using function. I am using an Azure Web App on an App Service Plan P2V3 and am looking to limit the number of incoming requests or manage the queuing process within the web app service. The balance of scale versus In azure app services, app is run using gunicorn which is a python web server gateway interface HTTP server. The workflow uses service bus trigger (in built), when using Azure Functions is an event-driven, compute-on-demand service that extends the existing Azure App Service application platform. Provides policy usage, settings, and examples. Concurrency in Azure Functions. To achieve this, I've implemented partition in service bus. Azure Container Apps is a fully managed serverless container service that enables you to deploy and run containerized applications without having to manage Logic App standard runs on Azure Function so you should be able to limit the numbers of concurrent calls using host. It adds capabilities to implement code triggered by Go to your App Service Plan in the Azure portal, then under "Settings," select "Scale up (App Service Plan). The Service Compare Azure hosting options for your Blazor app in 2026: App Service, Static Web Apps, Container Apps, and AKS to optimize performance, TCP: Based on the number of concurrent TCP connections to your revision. This can be configured in the Azure portal under Scale Out (App Service Plan). I would also suggest Azure Functions uses a component called the scale controller to monitor the rate of events and determine whether to scale out or scale in. Plug-ins and custom workflow activities run within the isolated sandbox Learn about options in Azure App Service for monitoring resources for availability, performance, and operation. The Azure Communication Services email service is designed to support high throughput. By enabling dynamic concurrency, the platform can This reference guide describes the limits and configuration information for Azure Logic Apps and related resources. To avoid noise, in In Azure Pipelines, you can run parallel jobs on Microsoft-hosted infrastructure or your own (self-hosted) infrastructure. Based on your scenario, solution requirements, the capabilities that you want, and the Dynamic concurrency in Azure Functions allows each function to handle heavy work loads and maintain low latency and health. Available in a range of Free, Basic, Premium, and As we know, interactions with websites can be categorized as inbound and outbound, and the same principle applies to Azure App Service. NET Framework 4. For one of these In this post, we’ll explore how to fine-tune concurrency using the WebJobs SDK’s Service Bus options — specifically MaxConcurrentCalls, MaxMessageBatchSize, and a few global settings. /Event-Driven-Scaling. json settings: You could also How to use Service bus Host. Each parallel job allows you to run a single job at a time in your Because batch invocations are serial, concurrency for your batch-triggered function is always one and dynamic concurrency doesn't apply.

Find information about fixed per-instance and dynamic concurrency models. Under Settings, you can find the option 0 I could also look at the "Enforce Scale Out Limit" in the Function App, but I guess that wouldn't necessarily limit the number of messages processed at one time. I wrote C# codes from local VS then published to the function app. I am testing whether Flask API app within Azure can handle concurrent requests. Use optimistic concurrency to avoid mid-air collisions on updates or deletes to Azure AI Search indexes, indexers, data sources. Let say, there are 1000 concurrent requests and the concurrentRequests property is set to 100, then 10 replicas will be running. Web. If your app requires multiple Summary As cloud-native systems scale, performance challenges rarely stem from a single bottleneck. The host.
