Using Ultra SSD Storage with Azure Kubernetes Service

In a previous post, I performed a storage performance benchmark of Azure Managed Disks and Azure Files for Azure Kubernetes Service. The testing included the now generally available Ultra SSD class of Managed Disk. The process for using Ultra SSD with AKS was fraught with peril, caveats, and an assist from the AKS product group to get it all working. I thought I would detail how I went about enabling Ultra SSDs with AKS in case someone else was struggling with the same.

Storage Showdown at the AKS Corral

This is a follow-up post to my analysis of using Azure NetApp Files for AKS storage versus the native solutions. After I wrote the post, with some surprising findings about Azure File performance, a number of people from Microsoft reached out to bring up a few key facts. In this post I will review the points that they brought up and include an updated analysis of the native Azure storage solutions for the Azure Kubernetes Service. Hold on to yer butts everyone!

Azure NetApp Files Performance with Azure Kubernetes Service

In April of 2018, I was delegate for Cloud Field Day 3. One of the presenters was NetApp, and they showed off a few different services they had under development in the cloud space. In a previous post I went over the services in some detail, so I won’t regurgitate all that now. One of the services that was still in private preview at the time was NetApp Files for Azure. The idea was relatively simple, NetApp would place their hardware in Azure datacenters and configure the hardware to support multi-tenancy and provisioning through the Azure Resource Manager. That solution is now generally available, and I was curious how it would perform in comparison with the other storage options for the Azure Kubernetes Service (AKS). In this post I will detail out my testing methodology, the performance results, and some thoughts on which storage makes the most sense for different workload types.

Demystifying Azure AD Service Principals

Anyone who’s worked with Azure for a bit has encountered the need to create a service principal. If you are an IT Ops person, you probably equate an SP with a service account in local Active Directory. If you’re more of an application developer, then you may have created an SP as part of your application in Azure, because you want to give that application permissions to Azure resources. The purpose of this post is to tease apart what service principals are, how they interact with application objects, and all the myriad ways to create an SP on Azure.

Cloud Field Day – Kemp

I will be a delegate for Cloud Field Day 5 on April 10-12. During the event we will be attending presentations from several vendors, which will be livestreamed. Before I leave on this grand adventure, I wanted to familiarize myself with each of the presenters and consider how their product/solution integrates with cloud computing. I’m also interested to hear from you about what questions you might have for each vendor, or topics you’d like me to bring up. As a delegate, I am meant to represent the larger IT community, so I want to know what you think! In this post I am going to consider Kemp and what a load balancer company can do in the cloud better than the native tooling.
