IO Performance in Azure Explained
I recently had a customer ask several questions about what IOPS and max throughput mean and how they could increase throughput so that their backup restore process in Azure would take less time. In this post we’ll look at how we can estimate our max throughput and IOPS based on VM size and disk configuration. Additionally, we’ll also look at ways to improve performance without increasing costs.
Migrating a non-HyperV VM to Azure
Let’s have some fun in this post moving a virtual machine from VirtualBox on MacOS to Azure. This can be a little tricky because not only do you have to prep the VM as you normally would for Azure but you also have to package up the HyperV modules so you can be used at boot time once moved. Personally, I would recommend Infrastructre as Code (IaC) and configuration management software typically for this kind of thing, however, sometimes that’s not an option so in this post we’ll look at moving a VM from MacOS (no HyperV) to Azure (HyperV) and what it takes to get there.
AKS with cert-manager and Prometheus
In this post we’ll take a look at a new script that I wrote to quickly build a Kubernetes (AKS) cluster with several core components preconfigured and installed out of the box. As a CSA for Microsoft I sometimes need to create an AKS cluster that goes beyond the cluster you get with the az command and I got tired of installing ingress controllers, cert-manager, and the like over and over. If your use case is similar to mine you should get some usefulness from this.
Azure Hub and Spoke Network with Terraform
In this post we’ll take a look at using Terraform to setup an Azure environment that implements a Hub and Spoke network topology using Linux as a Virtual Network Appliance (ie router). This post will setup the custom route tables that allow the individual spoke networks to communicate through the Hub VNet as well as provision an NVA in the Hub VNet.
Using SSH Tunnel with RDP
In this post we’ll take a look at what it takes to connect to an Azure DevTest Lab when you only have outbound access to connect to resources on port 443. I was recently working with a customer who could only connect outbound on port 443 and they wanted to use Remote Desktop Protocol (RDP) to connect to a Windows VM running in a DevTest Lab. There are a few different ideas that we came up with but using SSH was a quick and dirty solution that got them connected quickly.
Publish a Jekyll Website with Azure DevOps
Haven’t you always wanted to setup your website so that every change you make to your repo produces the cooresponding change in production automatically? Well in this post we’ll look at how to setup Azure DevOps to monitor a GitHub repository that contains a Jekyll website and compile and publish on every commit to master.
Query Log Analytics from the Command Line
I’ve been doing some work with Azure Log Analytics lately and found the az tool limiting as it relates to querying Log Analytics. So like anyone who gets an itch and needs to scratch it, I decided to put something together myself to help make it a bit easier for me. So using Python and some awesome modules I wrote a little utility that could query Log Analytics and provide data back in a few different formats.
