Azure Service Bus

Overview

Azure Service Bus is a fully managed enterprise message broker for decoupling applications and services.

Real-life Use Cases

• Cloud Architect: Design event-driven microservices architectures.

• DevOps Engineer: Buffer jobs for background processing.

Terraform Example

resource "azurerm_servicebus_namespace" "main" {
  name                = "myservicebusns"
  location            = azurerm_resource_group.main.location
  resource_group_name = azurerm_resource_group.main.name
  sku                 = "Standard"
}

Bicep Example

resource sbNamespace 'Microsoft.ServiceBus/namespaces@2022-10-01-preview' = {
  name: 'myservicebusns'
  location: resourceGroup().location
  sku: {
    name: 'Standard'
    tier: 'Standard'
  }
}

Azure CLI Example

az servicebus namespace create --resource-group my-rg --name myservicebusns --location westeurope --sku Standard

Best Practices

• Use topics and subscriptions for pub/sub.

• Enable geo-disaster recovery.

Common Pitfalls

• Not setting message TTLs.

• Ignoring dead-letter queues.

Joke: Why did the Service Bus message get lost? It missed its queue!
