Azure Logic Apps Standard: Single Tenant & VS Code

Historically, Logic Apps were a shared SaaS offering. Logic Apps “Standard” creates a single-tenant runtime (on top of Azure Functions), enabling local development, VNET integration, and reliable performance without “noisy neighbors.”

Local Development in VS Code

Since it’s built on the Functions runtime, you can run workflows locally!

// workflow.json - The definition
{
  "definition": {
    "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
    "actions": {
      "HTTP": {
        "type": "Http",
        "inputs": {
          "method": "GET",
          "uri": "https://api.example.com/data"
        }
      }
    },
    "triggers": {
      "Recurrence": {
        "type": "Recurrence",
        "recurrence": {
          "frequency": "Minute",
          "interval": 5
        }
      }
    }
  }
}

Stateful vs Stateless

• **Stateful**: Default. Checkpoints every action to storage. High reliability, lower throughput.
• **Stateless**: Runs in memory. High throughput, low latency. Great for request/response APIs.

Key Takeaways

• Use **Standard** for enterprise integration requiring VNETs.
• Use **VS Code** to treat workflows as code (Git versionable).
• Stateless workflows are a game changer for high-volume processing.
