As more businesses rely on Azure Virtual Machines (VM) for their operations, managing costs effectively has become a common concern. Recently, several clients have reached out asking how to reduce Azure usage costs, especially for VMs. This guide provides a straightforward overview of the factors that drive Azure VM expenses and practical steps users can take to minimize unnecessary charges. Whether you’re new to Azure or looking to refine your current setup, this text will give you an understanding of what’s involved in optimizing usage costs and how to make the most of your resources.
What is an Azure Virtual Machine?
An Azure Virtual Machine is a service provided by Microsoft that allows users to create and use a “virtual” computer in the cloud. Think of it as a computer you can access online instead of having it physically in front of you. This virtual computer can run programs, store data, and handle various tasks, just like a physical one. Businesses use Microsoft Azure VMs for everything from testing software to running applications, as they offer flexibility, scalability, and don’t require buying or maintaining physical hardware.
Why Use Azure Virtual Machines?
Azure Virtual Machines offer a powerful, flexible solution for businesses looking to run applications, store data, and support various workloads without the need for on-premises hardware. VMs in Azure allow organizations to create and manage virtualized environments at scale, adapting to changing business needs with ease.
Managing Azure VM Costs: Key Considerations
Effectively managing costs in Azure Virtual Machine usage involves understanding what drives expenses—even when VMs aren’t actively used. Below are key factors that can impact billing and strategies to minimize unnecessary charges, helping you make the most of your Azure resources.
Cost-Driving Factors in Azure VM Usage
Idle Running VMs
- Even if a VM is not actively used (i.e., no one is logged in, or there are no active processes running), it will still incur compute costs as long as it is running. This is because Azure bills based on runtime status, not actual usage or activity within the VM.
Unnecessary Resource Allocation
- Resources like CPU and memory are still allocated to the VM, regardless of if they’re being fully utilized. This reserved allocation of Azure’s hardware resources results in compute charges.
- If the VM size (CPU, RAM) is higher than required for the workload, costs may be higher than necessary, even for light use.
Continuous Disk Storage Charges
- Much like RAM and CPU, Disk storage charges are based upon GBs allocated to the machine – not how much “Stuff” you have stored on the VM. Deleting items from your VM won’t reduce charges but reducing the total available disk space will.
- If you want to reduce your overall disk space Professional Computer Concepts can make these adjustments for you on the back-end.
Network Egress Charges
- Data transferred out of Azure (network egress) to the internet incurs charges. For example, if applications on the VM are configured to regularly sync, backup, or transfer data outside of Azure, this activity will contribute to monthly costs.
- Internal network transfers (within Azure regions) are usually free or low-cost but should still be monitored if users are generating significant traffic.
Automatic Backups and Snapshots
- If the VM has automated backup or snapshot policies in place, each backup or snapshot creates a storage footprint. Over time, these snapshots or backups can accumulate, leading to higher storage charges.
Running Services or Processes in the Background
- Certain background services, especially those that communicate externally (e.g., database syncing, data analytics, or batch processing tasks) may continue consuming resources and network bandwidth, even if users aren’t actively using the VM. These background activities can indirectly increase Azure bills by contributing to resource usage.
While users cannot shut down the VM, optimizing storage use, managing background processes, and limiting unnecessary data egress can help control Azure costs.
Understanding the Impact of Cost-Saving Changes
While optimizing Azure Virtual Machine usage can help control costs, the actual impact of these adjustments varies depending on your usage level. For businesses or users with high-intensity workloads or large numbers of VMs, implementing these strategies can lead to substantial savings. However, if your Azure usage is lighter, some of these optimizations may have a more limited impact on your overall charges.
Unless you’re a power user managing significant resources, smaller adjustments—such as reducing storage or right-sizing VMs—may result in only modest savings. For users with basic or moderate needs, focusing on core strategies like reviewing storage use, selecting appropriate VM sizes, and monitoring network egress can help you avoid unnecessary costs without significant complexity.
