Configuring the Web Application Firewall with PowerShell.

A quick guide on how to connect and work with the Azure WAF from PowerShell.

Microsoft Azure Application Gateway is a Layer 7 application delivery controller (ADC) offered as a service in Azure. It provides load balancing, SSL termination, end-to-end SSL, URL path-based routing, and basic web application firewall (WAF) functionality.

My Journey to the Internet of Things

While preparing to use the NodeMCU, Reminiscing IoT evolution after 20 Years

In a previous post, I referred to an embedded device which is called a NodeMCU. This device is a developer kit, designed to make it easy to develop and test programs for the embedded ESP8266 System on a Chip. Many manufacturers are offering both developer and production kits which leverage this SoC; including the Wemos D1, Lolin, and in my case the NodeMCU. The function of these developer kits is to add some supporting features, for example, a USB to serial converter which makes programming a lot easier, in addition to a couple of buttons, and maybe an LED or two, for testing some simple scenarios with.

Over the last number of years I have deployed various Raspberry PI’s around my home, to add more features to how we interact in the house. However, as wonderful as the PI is, there are alternative options available which are more appropriate to the various tasks which I need to address.
