The Azure event provider distributes events across load-balanced Optimizely Content Management System (CMS) 13 instances through Azure Service Bus. Use it to keep caches, content, and configuration in sync without managing server or network details.

:::hint{type="info"}
**Note**
Add the `EPiServer.Azure` package to your solution. This package provides the `AddAzureEventProvider` extension method on the `IServiceCollection` interface.
:::

Register the Azure event provider in `Startup.cs` and supply your Service Bus connection details. The following example shows the required configuration:

```csharp
using Microsoft.Extensions.DependencyInjection;
using EPiServer.DependencyInjection;
using System;

namespace SampleBlob;

public class Startup {
  public void ConfigureServices(IServiceCollection services) 
  {
    services.AddAzureEventProvider(o => {
      o.ConnectionString = "AZURE_EVENT_CONNECTION_STRING";
      o.TopicName = "TOPIC_NAME";
      o.SubscriptionName = "SUBSCRIPTION_NAME";
    });
  }
}
```

**Note**
This article does not apply to Optimizely Digital Experience Platform (DXP) CMS 12.

For DXP with CMS 12, follow the steps in [Create and deploy a CMS site](docId\:RIn0cobbPnEmEafa16av8). Use the `EPiServer.CloudPlatform.Cms` package and the associated startup code to connect to the event system in Azure.
