Azure Application Gateway Anatomy

Back in May, we talked about Azure Application Gateway.

In this article, we’re going to look at its anatomy, i.e. its internal component as exposed in the Azure Resource Manager (ARM) model.

A lot of Azure Resource has an internal structure.  For instance, a Virtual Network has a collection of subnets.

Azure Application Gateway has a very rich internal...

Hypersphere Volume

In our last article we looked at how the dimension of data space impacts Machine Learning algorithms.  This is often referred to as the curse of dimensionality.

At the heart of the article we discussed the fact that an hypersphere hyper-volume trends to zero as dimension increases.

Here...

Hyperspheres & the curse of dimensionality

I previously talked about the curse of dimensionality (more than 2 years ago) related to Machine Learning.

Here I wanted to discuss it in more depth and dive into the mathematics of it.

High dimensions might sound like Physics’ string theory where our...

URL Routing with Azure Application Gateway

Update (13-06-2017):  The POC of this article is available on GitHub here.

I have a scenario perfect for a Layer-7 Load Balancer / Reverse Proxy:

• Multiple web server clusters to be routed under one URL hierarchy (one domain name)
• Redirect HTTP traffic to the same URL on HTTPS
• Have reverse proxy...

Automating Role Assignment in Subscriptions & Resource Groups

Azure supports a Role Based Access Control (RBAC) system.  This system links identity (users & groups) to roles.

RBAC is enforced at the REST API access level, which is the fundamental access in Azure:  it can’t be bypassed.

In this article, we’ll look at how we can automate the role...
