This video goes over two Azure IP addresses used for Azure VM’s. The WireServer IP of 188.8.131.52 and the Azure Instance Metadata Service (IMDS) IP address 169.254.169.254. In the video, I go over what each is used for and then give a demonstration on using the WireServer IP address to query DNS. After that, I use the IMDS REST Endpoint to pull metadata including the Azure environment and scheduled events.Continue reading “Two Azure IP Addresses You Need to Know About”
Azure Spot Virtual Machines are an IaaS server option offered at a deep discount compared to pay-as-you-go and Reserved Instance pricing. This video walks through deploying the new Azure Spot VM’s with the Azure Portal. The video also gives an overview of what Azure Spot VM instances are and some considerations to using them.Continue reading “New! Azure Spot Virtual Machine”
Reserved Instances offer significant savings for IaaS Servers, SQL Databases, Cosmos DB and other Azure and third party services. I have mentioned Reserved Instance in a couple other videos and posts. One on Saving money in Azure and once on Azure Cost Management. LINKS. This article and the accompanying video go into details on how Azure Reserved Instances worth.
Video version, including a demo can be found below.Continue reading “Reserved Instances in Azure”
My first article posted at 4sysops on setting up an Azure Monitor workspace in Log Analytics and onboarding Servers.
Azure Automation Update Management is part of Azure Automation. In this video, I’m going over updating servers using Azure Automation Updates. Topics covered include: Continue reading “Update Management in Azure Automation”
ARM Templates are written with JSON and are at the core of Azure Resource Manager deployments. I have used and developed templates for months. Although successful, I ran into issues with formatting and syntax this week and decided to take a step back and get a better understanding of the underlying JSON used in these templates. In this post, I start from the beginning, exploring JSON as it relates to ARM templates. Continue reading “JSON and ARM Templates”
This week I noticed an issue with no data showing in the Azure Network (Total), Network Out (Sum) and Network In (Sum) tile in the Azure Virtual Machine Overview. I recall noticing this before but couldn’t remember how long ago that was. Looking at other VM’s, most of my them were missing the Network Total information. The only servers that were showing data are virtual firewall appliances. Continue reading “No Data in Network Overview Tile”
I took some time off to chase fish on Lake Minnetonka this week and missed Microsoft’s announcement of Azure B-Series are now in preview. The fish were not cooperating so I’m posting about Azure instead. The B-Series VM significance is their ability to “bank” CPU credits during time of low CPU usage and to use these credits during CPU spikes. This will be helpful for test servers that may be idle during off hours or applications servers that have bursty work loads. Any opportunity to save money without impacting performance is good news to my ears.
Next, maybe dynamic RAM allocation???
