What Happened? Hey folks, Let me share a real incident we faced in production on Azure Kubernetes Service (AKS). Our workloads were behaving oddly — pods getting evicted, app downtime alerts, and our monitoring tools screaming DiskPressure on some nodes. We didn’t make any infra changes recently, so the obvious question was: What’s going on inside the AKS nodes? Root Cause Analysis We dug into the node metrics using Azure Monitor and kubectl describe node. Here’s what we found: ...

In one of my recent automation projects, I came across a real-time scenario: An Azure Alert once condition met (example:VM’s C:\ drive crosses 80% usage), and boom — the alert triggers, gets routed to Moogsoft, and creates an incident in ServiceNow. But before it even hits the L1 queue, I wanted to give automation a shot. Why assign alert/incident (disk cleanup) to an engineer when a bot can do it better — and faster? Real Scenario Here’s what happens traditionally: ...

Azure Bicep is a domain-specific language (DSL) that simplifies ARM templates. If you’re used to Terraform or ARM JSON, Bicep offers a cleaner, more concise syntax — tailor-made for Azure. Why Bicep? Native to Azure Simplified syntax No state files (unlike Terraform) Excellent tooling in VS Code Install Bicep CLI az bicep install Verify installation: az bicep version 🏗️ Sample Bicep Template: ------------------------- resource storageAccount 'Microsoft.Storage/storageAccounts@2022-09-01' = { name: 'kasdevstorage${uniqueString(resourceGroup().id)}' location: resourceGroup().location sku: { name: 'Standard_LRS' } kind: 'StorageV2' } 📦 Deploy using Azure CLI: -------------------------- az deployment group create \ --resource-group kasdevtech-rg \ --template-file main.bicep Next Steps Use modules to reuse code Integrate Bicep in DevOps pipelines Combine with Azure Policy for compliance ...

In this post, we will cover: Setting up Terraform CLI Writing your first Terraform configuration Deploying resources on Azure Steps Install Terraform CLI Configure your Azure credentials Write main.tf with Azure provider Run terraform init, plan, and apply Conclusion Terraform allows you to automate cloud infrastructure — making deployments reproducible, version-controlled, and consistent. ...

Resizing an Azure Virtual Machine (VM) allows you to adjust the size (CPU, Memory, Disk) of the VM as your application needs change — for cost optimization, performance scaling, or seasonal traffic. In this guide, we’ll walk through how to resize an Azure VM in 2025 using both the Azure Portal and CLI. Why Resize VMs? Scale Up: Handle more traffic or workload Scale Down: Reduce costs for low-traffic periods Change Type: Move to different series (ex: from DSv2 to B series for dev/test) Pre-requisites Azure Subscription Owner / Contributor permissions on the VM VM must be in a Stopped (Deallocated) state to resize Resize via Azure Portal 1️ Navigate to Virtual Machines 2️ Select your VM 3️ Click Size under the “Settings” section 4️ Select a new size (you will see estimated cost/month) 5️ Click Resize ...
