Operations Management Suite / Log Analytics: What is it?

This blog post will start off a series of blog posts about Operations Management Suite (OMS or Log Analytics) which is as the latter name suggests is a log analytics engine that ingests events from data sources that you provide and provides a very nice searchable interface where you can do auditing on your infrastructure where ever it is.

Backing up your Azure Resource Manager VMs

Azure Backups has been GA for a long time now but not long ago, the folks at Azure just removed the preview tag from the service that handles backing up Resource Manager VMs. I’ve been testing Azure Backup on RM deployments since it was announced in preview and I can say that almost all my tests showed promising results. I’ve encountered a couple of quirk during tests but those were ironed out fast and now that the service is out of preview I can say that Resource Manager VM deployments are the way to go.

In this blog post I will show you how to configure the Azure Recovery Services to back up your Azure VMs and recover them when required.

Using PowerShell DSC in Azure

Most of my DSC blog posts target on-premise or remotely accessed VMs which most of the times are in Azure. While everything is fine and dandy when you’re running PowerShell / PowerShell DSC on your local infrastructure, but when it comes to Azure, you might need to rethink your strategy a bit.

ARM Templates for creating custom image VMs in Azure

If you worked with Azure for a long time, you know that when you wanted to upload your own custom VM image to Azure, it was an easy thing. You prepared the VM, you sent it to Azure using PowerShell and after that you tagged it as an OS disk and that was it. Well that was the old way using the Azure Service Manager which I must say it was quite an easy procedure. With Azure Resource Manager, things changed quite a bit. You still have the possibility of uploading the VHDs to Azure but the deployment requires a little more work. You have to write code for that deployment to happen, be it in PowerShell or JSON. In this blog post I’m going to give you two ARM templates which you can use to deploy your freshly uploaded VHDs.

PowerShell Scripts to add / remove data disks on Azure VMs

First things first. Happy New Year!

So after I finished a long waking up cycle I remembered working on a project that involved migrating some SQL workloads to Azure and those workloads required a high amount of IOPS in order to perform optimally. Now after testing the storage system of the on-premise servers I found that they were capable of delivering about 2000 IOPS which is not much and that was with 15K RPM spindles configured in a RAID 5. Now achieving 2000 IOPS in Azure is very easy from a hardware perspective. On a Standard type of VM, one data disk can offer 500 IOPS so you would need four data disks and then configure a software RAID to stripe the data across all disks. This can be done on Windows using Storage Spaces or MDADM if the operating system is Linux.
