How do I reduce the cost of a VM in Azure?
Over the last 5 years or so, many organizations have moved their infrastructures and additional resources to Microsoft Azure. According to InfoClutch, over 280,000 companies use Azure worldwide, which made cloud costs (and their optimization) a large part of most businesses’ IT budgets. Show
There are various built-in pricing models to help you with your Azure cost management and numerous tools to assist you with optimizing your budget, but the process of focused cost optimization that can truly make a difference comes with experience and expertise. Reducing waste and unnecessary overheads can come in handy when you seek new ways to maximize your utilization of existing resources. In this blog post, we’ll tackle seven cost-saving best practice options that can help you make the most out of your Microsoft Azure architecture and optimize your monthly spendings. 1. Move to Elastic Databases (from Traditional Database Servers)Running MS SQL or other database servers on Azure can turn into quite an expensive perk, and the increase in costs can happen rather quickly. Virtual Machines could be expensive, while database instances are often not utilized in an optimal way, which makes database VMs inappropriate and not the most straightforward way to distribute loads between instances, especially if you are looking to cut your overall Azure costs. This is why transitioning to PaaS is the best solution for many organizations. Most companies that move to the Azure SQL service report a substantial reduction in costs. This reduction is mainly due to a more dynamic payment method in which you are paying only for the database resources you are actually using at that given moment, allowing for the cost-effectiveness on a more granular level. Best Practice Tip: Use SQL Elastic PoolsUsing SQL elastic pools beats the practice of reserving a certain amount of resources for a single database instance as the utilization of this model allows you to reserve a number of resources that can be shared across hundreds of databases. SQL elastic pools provide all the advantages of Azure SQL while enabling you to handle spikes in usage patterns across multiple databases more effectively. This solution has proven to be very reliable and popular among businesses with multi-tenanted applications. On the other hand, in a scenario where you have a database with dramatically higher usage compared to other databases in your elastic pool, you may need to purchase a more expensive elastic pool tier so it can properly withstand usage peaks. In this situation, the most cost-effective solution is to take the high-usage database out of the pool by splitting it out into single database offerings. This will allow you to pay for a less expensive elastic pool tier you will use for low-usage databases. We recommend you to check the database DTU usage and if you notice that a single database has 40% or more of usage in your DTUs at any given time, it almost certainly means that there’s room for a significant saving in costs. However, as DTU can be somewhat unreliable, we highly suggest checking the database metrics regularly to make data-driven choices accordingly. Best Practice Tip: Use Serverless Azure SQL This single database compute tier in Azure SQL Database is designed to automatically scale the computing power and usage according to the workload demand. Serverless databases bill their users for the amount of computing power used per second, while it can also automatically pause the database when inactive and resume activity when necessary, during which periods you only pay for storage. 2. Use Storage TieringSince storage is often among the largest portions of ongoing Azure costs, optimizing this aspect of Azure deployment can bring significant reductions in overheads. Azure Blob Storage model offers Premium, Hot, Cool and Archive storage tiers, each with appropriate pricing per GB a month. Using the right storage tier for the right type of data can be very cost-effective. For example, storing the data you access less frequently on a lower-cost tier is a good automation practice as it decreases monthly costs and allows a substantial cost reduction in the long run. 3. Shift Workloads to ContainersContainers account for a more lightweight workload architecture when compared to VMs. Depending on your workflow and resources, businesses can run numerous containerized applications on a single physical host, and in certain cases manage dozens of containers per host. Companies that repackage their applications as containers are able to reduce the utilization of virtual machines and therefore reduce costs even further. Important Note: |
