0.09 ms latency using Azure Proximity Placement Groups

Reducing network latency for critical apps running on Azure IaaS has become easier since Microsoft’s announcement of General Availability for Proximity Placement Groups (PPG) on Dec 2019.

Today I’ll give you a quick intro to Proximity Placement Groups demonstrating how to deploy a test environment into your Azure Subscription using one of my favourite tools AzureCLI. I’ll also test network latency with a PPG and without to show you the difference.

If you’re undecided about using AzureCLI or ARM templates for your Azure deployments have a look @ Pascal Naber’s post https://pascalnaber.wordpress.com/2018/11/11/stop-using-arm-templates-use-the-azure-cli-instead/

Automating the creation of Azure IoT Hubs and the registration of IoT Devices with PowerShell and VS Code

The creation of an Azure IoT Hub is quick and simple, either through the Azure Portal or using PowerShell. But what can get more time-consuming is the registration of IoT Devices with the IoT Hub and generation of SAS Tokens for them for authentication.
In my experiments with micro-controllers and their integration with Azure IoT Services I often find I keep having to manually do tasks that should have just been automated. So I did. In this post I’ll cover using PowerShell to;

  • create an Azure IoT Hub
  • register an Azure IoT Device
  • generate a SAS Token for the IoT Device to use for authentication to an Azure IoT Hub from a Mongoose OS enabled ESP8266 micro controller

IoT Integration

Prerequisites

In order to fully test this, ideally you will have a micro-controller.… [Keep reading] “Automating the creation of Azure IoT Hubs and the registration of IoT Devices with PowerShell and VS Code”
