Change the replication type of an Azure storage account

Last year I wrote a blog post about migrating an Azure storage account from LRS to ZRS replication. -> https://www.danielstechblog.io/migrate-an-azure-storage-account-from-lrs-to-zrs-replication-without-downtime/ Back then, this procedure required the involvement of Azure support via a support ticket. Things have changed since then, and now you can initiate the migration yourself. Select Read more [...]

Migrate an Azure storage account from LRS to ZRS replication without downtime

This is a rather short blog post about a hidden gem in the Azure documentation. You have two options today migrating an existing Azure storage account from the LRS (locally redundant storage) to ZRS (zone-redundant storage) replication option. A manual migration or live migration. Choosing the manual migration option requires a new target storage account with ZRS and might imply an application Read more [...]

Conditions with for_each in Terraform

Conditions in Terraform are well-known and can provide in combination with the for_each argument a lot of flexibility. In today’s blog post I walk you through an example storage module I have created to showcase the topic. The module consists of three resources a resource group, a lock, and a storage account. As I am using conditions with for_each for the resource group and the lock I can decide Read more [...]

Automate taking backups from Azure disks attached to Azure Kubernetes Service

At the beginning of 2019 I wrote a blog post about taking backups from Azure disks attached to an Azure Kubernetes Service cluster. -> https://www.danielstechblog.io/taking-backups-from-azure-disks-attached-to-aks-via-azure-automation/ Since then, some things changed. Azure Function PowerShell support went into public preview in April 2019 and the AzTable (AzureRmStorageTable) module I use Read more [...]

Taking backups from Azure Files attached to AKS via Azure Backup

In one of my last articles I showed you how to automate the backup process for Azure Disks attached to AKS. -> https://www.danielstechblog.io/taking-backups-from-azure-disks-attached-to-aks-via-azure-automation/ Today we look at the process for the second natively supported Azure storage option in Kubernetes on Azure, Azure Files. The good news is that we can use Azure Backup with its support Read more [...]

Taking backups from Azure Disks attached to AKS via Azure Automation

When you followed the Azure docs on how to dynamically create Azure Disks via a Kubernetes PVC, you saw the instructions to create a backup of the disk. Snapshots are leveraged for this. But it is a manual task you must accomplish. -> https://docs.microsoft.com/en-us/azure/aks/azure-disks-dynamic-pv#back-up-a-persistent-volume It would be nice to have an automated solution which also take Read more [...]

Using dysk in Azure Kubernetes Service – AKS cluster upgrade and its learnings from it

In one of my previous blog posts I have explained how to use dysk in Azure Kubernetes Service as persistent storage option. -> https://www.danielstechblog.io/using-dysk-in-azure-kubernetes-service-as-persistent-storage-option/ Today we have a look how a Kubernetes version upgrade of an AKS cluster effects dysk in operations and may force you to rethink your chosen Azure VM and OS disk SKU. First Read more [...]

Using dysk in Azure Kubernetes Service – updated deployment templates

In one of my last blog posts I have explained how to use dysk in Azure Kubernetes Service as persistent storage option. -> https://www.danielstechblog.io/using-dysk-in-azure-kubernetes-service-as-persistent-storage-option/ Since then some of the dysk parts have been moved to the official Azure GitHub repository. -> https://github.com/Azure/kubernetes-volume-drivers Comparing the deployment Read more [...]

When you are running stateful microservices on your AKS cluster and you are looking for a persistent storage options beside native Azure PaaS services like Cosmos DB, Azure SQL Database, Azure Database for MySQL or Azure Database for PostgreSQL, then you have two options. Per default Kubernetes supports Azure Disk and Azure File as storage classes natively. -> https://kubernetes.io/docs/concepts/storage/storage-classes/#azure-disk -> Read more [...]

Does have ADE or SSE a performance impact on Azure IaaS VMs?

Before I begin to write about this topic, I want to clarify that the results are not an official statement by Microsoft. The opinions expressed herein are my own personal opinions and do not represent my employer’s view in anyway.
