I recently overhauled a script that I wrote to take advantage of the parallel processing functionality that is included in Microsoft Powershell 7. The results have been excellent with script runtimes being reduced from over an hour down to roughly 5 minutes. Learning the ins-and-outs of using parallel processing was a bit of a chore that I will discuss in a later article, however the first hurdle that had to be mounted was simply getting Powershell 7 installed and figuring out how to make use of it. Quickly getting up and running with Powershell 7 is what this article seeks to address. (more…)

I periodically review Azure PaaS resource edge security. As a part of that process I examine and cleanup AzureSQL firewall rules. Once you have more than a handful of subscriptions and AzureSQL databases, doing this manually starts becoming unfeasible. To that end, Azure Powershell is your friend…

As is typical, you need to install the Powershell AZ module on your workstation, after that you need to run.

Connect-AzAccount

Then supply your Azure credentials (preferably creds that have the ability to view and manage all of your AzureSQL databases and firewall rules, otherwise the rest is moot.

Continuing on my journey up the Azure Automation mountain, I recently completed a simple AZ PowerShell script that takes several input parameters and scales UP or scales DOWN a given AzureSQL database instance depending on what time of day it is.

Before I go any further, if you are just getting started in Azure Automation, I wrote another article here which may help you avoid some of the headaches I ran into as part of my initial foray:
Azure Automation – Powershell – Getting it Working – Authentication the “Easy” Way -and- Ditching AzureRM

BACKGROUND
Azure has excellent auto-scaling parameters built-in for scaling App Services horizontally (i.e. “out” and “in”… adding or decreasing instance count). However for vertical scaling of AzureSQL services, you are pretty much left to your own devices.

I have an “okay” amount of experience using AZ Powershell to script and get things done in my Azure Subscriptions and with that in mind and the task set in front of me of auto-scaling our AzureSQL databases based on time of day (scale up before the busy hours, scale down when the quiet hours start) I turned to Azure Automation to get the work done.

Being an IT professional of several years, I did what we all do… I turned to Google and searched for scripts I could just steal, modify, and use (I am nodding at you right now…). However, if your want to use “AZ” Powershell instead of the deprecated “AzureRM”… I think the term is… “forgetaboutit.” The templates and examples that I found were either based on Powershell “Workflows” which I didn’t want to mess with and/or used the old AzureRM Powershell syntax. So I then turned to… Powershell ISE… and started writing.

I have been using Powershell to manage pieces of Azure on and off for about a year and half now. I had heard tell of Azure Automation but never really had a good reason to justify spending the time climbing that particular mountain (hill really…).

Then the request came through… let’s scale AzureSQL databases up and down based on time of day for a given project… If you have worked in Azure you know Microsoft has built in a fairly robust and relatively easy to use auto scale-out configuration interface for Azure App services. Not so for “up/down” scale operations (increasing/decreasing the size of a single-instance). Hence, my foray into Azure Automation.

I have done a fair bit of Azure Powershell scripting just using the ISE interface and keeping scripts on my desktop. I started out with “AzureRM” and migrated to “AZ” as Microsoft starting a couple of years ago pretty much said “AZ” is the future… switch now.

With that background in place, I will state that I found starting out on Azure Automation to be a bit of a bumpy ride. I wanted to hopefully save you the reader some of the time I spent chasing my tail…
