Azure Infrastructure-as-a-service (IaaS) offers significant benefits over traditional virtualization. With benefits like the possibility to quickly spin up a couple of virtual machine in any Azure region around the world whenever you need it, is pretty powerful. There are a lot more benefits to Azure IaaS virtual machines. However, that’s not part of this blog. This blog post is focused on helping you saving money by reducing the costs when you are using Azure IaaS virtual machines (VM). Some of the tips here will help everyone out there; some tips only apply in specific cases.
Pick the right Azure VM series and the right Azure VM size.
First of all, obviously, you pay more for larger virtual machines. Something I realized by working with a lot of customers is that they take the on-premises VM size and use the equivalent size in Azure. Not realizing that the VM size they had was way to oversized. But since they had the static capacity on-prem, they didn’t’ care. Now when you pay for more capacity in the cloud, the story is different. So make sure you realize that the Azure VM sizes are not oversized. You can still change the size later to a larger virtual machine if needed. And if you are looking at tools like Azure Migrate to migrate your existing VMs to Azure IaaS, you will have some additional advantages. Azure Migrate assess your environment and helps you pick the right Azure VM size depending on performance data history. Azure Migrate works with Hyper-V and VMware virtual machines. If you want to know more about Azure Migrate, check out my blog post. If you are already running the virtual machine in Azure, Azure Advisor can be helpful to figure out that your virtual machine is underutilized. Picking the right size will help you to save money and reduce the cost of Azure IaaS VMs.
