Microsoft Azure is the go-to cloud computing service for companies small, large, and everything in between. In fact, by Microsoft’s own estimations, Azure has over 68,000 partners and is the platform of choice for 95% of Fortune 500 companies, which is testament to its trustworthiness, reliability, and ease. And with Azure being the first choice for so many businesses worldwide, the costs of Azure now account for a large proportion of organizations’ IT budgets.
Of course, these costs depend on the type of Azure products you opt for. According to our very own Nigel Frank Salary Survey 2020/21, 71% of respondents were using Compute services, while 67% were using Databases and Storage; all of which can add up and really bulk out your organization’s expenses. So, it’s only to be expected that so many businesses are looking at cost-saving practices that can help them make the most out of their Azure architecture while optimizing their monthly spending.
Generally, Azure has various built-in pricing models to help you with the management of the products you’re using, as well as tools to optimize your choices to fit your budget, however with added expertise and experience, you can truly see the difference from focused cost optimization strategies.
Here, we will be taking a look at the top 8 ways you can make Azure cost savings when investing in and implementing it into your company’s IT strategy.
Using traditional databases like MS SQL and others can rack up your Azure expenses pretty quickly. To add to this, Virtual Machines (VMs) are often expensive and database instances are frequently used in a less than optimal way, meaning database VMs aren’t always appropriate way to distribute loads between instances.
For many organizations, transitioning to a PaaS is the best solution. By using PaaS infrastructure, you remove the need to perform low-level work or hire more people to set it up and maintain it that usually requires considerable amount of money to do. And, you’ll only be paying for the database resources you’re using at any given moment.
If your company is really looking to optimize your Azure costs, an SQL elastic pool might just be the answer. Doing this allows you to reserve many resources that can be shared across hundreds of databases, rather than reserving resources to use across a single database—your resources (and your money) will be able to stretch further, hence elastic. If you’re working with a database where the usage is much higher than that in your other databases, you may need to purchase a more expensive elastic pool tier to ensure your infrastructure can fully withstand the usage peaks.
To make really effective cost savings, consider using a serverless Azure SQL. This is designed to automatically scale computing power and usage according to the workload amount, meaning you are billed for computing power used per second and therefore only for what you use. On top of this, serverless SQLs can automatically pause the database when it’s inactive and resume when necessary, so you’re only paying for periods in which you actually used it.
Azure Virtual Machines (Virtual Machines) are designed with a range of hardware and performance capabilities, so finding the right one for your workload is important, to ensure you’re getting maximum performance while optimizing your Azure costs. It can take a while to find the right combination suitable for your unique projects, but once you’ve got it figured out be sure to keep it in place and use auto-scaling features to automatically adjust the number of VMs according to your actual workloads.
Containers are a much more lightweight way of storing your workloads, especially compared to Virtual Machines. Depending on your workflow and resources, you may be able to run numerous containerized applications on a single host, and sometimes manage many containers per host. Companies that can repackage their applications as containers will reduce the need for Virtual Machines, meaning their Azure cost optimization efforts will be even more effective.
Before you shift your workloads into containers, it’s important to note that doing this can sometimes increase your costs. So, make sure you’re speaking to an Azure expert about your unique project before you make any changes.
Although it’s not always possible, you should always aim for 100% VM utilization to ensure your costs are optimal. But how do you do this? By monitoring your metrics with Azure Monitor and using auto-scaling features to add and delete machines as and when you need them, according to your utilization percentage at any one time.
Because of the sheer amount of it needed for many businesses, storage can be one of the costliest parts of using Azure, so taking the time to consider how best to optimize this aspect can mean you greatly reduce your overheads.
Implementing a tiered storage model means you can keep costs lower depending on your project requirements. For example, the Azure Blob Storage model offers Premium, Hot, Cool, and Archive storage tiers with pricing to match, so you can discover what’s right for you. For example, if you’re looking to make quite significant Azure cost savings, storing your data on a lower-cost tier can decrease your monthly costs and can create a substantial reduction further down the line for you, as well.
To optimize your Azure costs properly, it’s highly recommended that you perform an analysis of your usage patterns and availability so you can create a VM stop/start schedule that is optimal for your individual business. Combine your custom scheduling with autoscaling and you’re sure to reap benefits including added elasticity, and better cost-effectiveness in the long run.
So, how can you do this? Azure Automation Runbooks gives you the tools needed to implement automatic stop/start functions. Scheduling your usage in this way can be effective, particularly in a test environment where you don’t always need to be operating. Alternatively, using autoscaling in VMSS is a great solution if your applications need to be run on VMs because of its inner mechanism which makes it easy to add or remove instances according to the autoscaling rule.
Currently Azure doesn’t have the option to automatically delete virtual disks when you delete a virtual machine from your infrastructure, because of this your costs can continue to go up without you knowing. To tackle this and better optimize your Azure costs, you’ll need to locate your unused virtual disks via the Disks screen in your Azure portal. Here, you’ll find all active managed virtual disks in your current storage account, and identify any without an owner which would imply it’s empty.
Should a disk have no VM, it’s likely you can then delete it to ensure you’re managing your Azure costs and not overpaying for parts you don’t need.
As well as your SQL server, it’s likely your app has further functionalities such as using queues and caching, other dependencies, and Azure features like CosmosDB and Azure Storage. But what can you use to track these app dependencies, and make further Azure cost savings down the line?
To make the most of your Azure cost optimization efforts, be sure that all your dependencies can be scaled well and performing optimally.
