Low-usage virtual machines can quickly skyrocket your cloud computing costs. You can save significant money by identifying low-usage virtual machines and reducing their size. Show
Azure provides various instance types to cater to different workload requirements and resource types. By allocating VMs according to their specialized purpose and workload requirements, you can avoid idle or unused VM resources and, in turn, significantly save your cloud computing costs. Calculating and optimizing the costs of your VMs is easier with the right tools and services. Microsoft provides Azure Cost Management, Azure Advisor, and Azure Pricing Calculator. Defining Low CPU UsageAzure Advisor identifies underutilized virtual machines by monitoring your virtual machine's usage for seven days. Virtual machines have low usage if their network usage is 7 MB or less and CPU utilization percentage is 5% or less averaged over four or more days. You can configure the average CPU utilization rule on a per subscription basis. It can be set to 5%, 10%, 15%, or 20% — 5% is the default setting. Blink Automation: Find Azure VMs with Low CPU Usage and Send Report to Slack Azure + Slack Try This Automation View Utilization of an Azure VMTo access a virtual machine's performance or utilization insights, perform the following steps.
The page shows performance utilization charts, CPU Utilization, Available Memory, Logical Disk Space Used, Logical Disk IOPS, Logical Disk MB/s, Max Logical Disk Used, and Bytes Sent and Receive Rate for each logical disk. Resizing Azure Virtual Machines with Low CPU UsageThere are multiple ways to resize Azure virtual machines. Virtual machines restart while resizing, so scheduling the restart can reduce disruptions caused by the unavailability. Resizing a Virtual Machine in Azure AdvisorAzure Advisor provides various cost optimization recommendations.
A notification appears when the VM resizes effectively. Resizing a Virtual Machine in Azure Portal
If the new size is unavailable on the hardware cluster hosting the virtual machine, deallocate the VM before resizing it. Note: Choose the s version of the virtual machine size that uses premium storage. Resizing a Virtual Machine in CLITo resize a VM using the Azure CLI, use the script below. You can also consider switching to a low-code platform like Blink to perform these tasks in a few clicks. 1. You can view the current size of a VM with az vm show. This script lists the VM size of "blinkVM" in the "blinkResourceGroup" region:
2. View the available VM sizes on the hardware cluster hosting the VM using az vm list-vm-resize-options. This script displays VM sizes for "blinkVM" in the "blinkResourceGroup" region:
3. If the desired VM size is listed, resize the VM with az vm resize. This script resizes "blinkVM" to the "Standard_D3_v2" size:
After the VM restarts, your data disks and OS are remapped. Data on the temporary disk is erased. 4. If the VM size you want is not listed, first deallocate the VM with az vm deallocate. Afterward, you can resize the VM to any available size supported by the region. The following steps deallocate, resize, and start the VM:
Any dynamic IP addresses assigned to the VM are released during deallocation. The OS and data disks are unaffected. Automate the Resizing Process with BlinkAs your business and engineering requirements evolve against internal operational needs and external market developments, your resizing efforts should be just as agile. Whether you want to aggregate reports on your CPU usage or navigate instance migrations, having an easy way to navigate the steps is critical. With Blink, you can automate this usage check and use no-code/low-code automations to manage and customize your resizing process. Get started and create your free Blink account today. Which of the following methods can be useful to reduce service costs using Azure advisor?Optimize virtual machine (VM) or virtual machine scale set (VMSS) spend by resizing or shutting down underutilized instances. Although certain application scenarios can result in low utilization by design, you can often save money by managing the size and number of your virtual machines or virtual machine scale sets.
