Azure SQL database cost optimization to maximize savings

Azure SQL is a versatile and powerful database service, and it is an increasingly popular choice for storing and managing application data due to its scalability, high availability, security, and simplicity of integration. A common demand for cloud workloads is cost optimization. To maximize cloud savings, this article discusses Azure SQL Database Cost Optimization.

Azure SQL Database pricing tiers

Azure SQL Database offers several services and compute tiers with different pricing options. It involves a vCore-based purchasing model and a DTU-based purchasing model.

vCore-based purchasing model

This purchasing model chooses between a provisioned compute tier, billed per hour, and a serverless compute tier, billed per second. You can also select the hardware configuration. The model includes three service tiers: General Purpose, Hyperscale, and Business Critical.

DTU-based purchasing model

This model offers a straightforward approach to provisioning and managing compute resources. It provides three service tiers: Basic, Standard, and Premium. The pricing is determined by the selected tier and the number of DTUs allocated to the database.

How to optimize Azure SQL Database cost?

Azure SQL Database (except for serverless) is billed at a predictable hourly rate. You are charged for the highest service tier chosen, provisioned storage, regardless of consumption or if the SQL database was active for less than an hour.

It is essential to monitor and optimize your database usage regularly. Here are some ways to save costs when using Azure SQL Database:

Right-size your resources

Choose the appropriate service tier and performance level for your workload. Consider the required computing and storage resources and select the most cost-effective options based on your application’s performance needs.

Monitor and optimize resource utilization

Regularly monitor your Azure SQL databases’ performance and resource utilization. Identify any underutilized or overprovisioned resources and make necessary adjustments to optimize costs. Azure Monitor and Azure SQL Analytics can provide insights into resource utilization.

Consider reserved capacity

Azure SQL offers reserved capacity pricing, where you can pre-purchase compute capacity for a one- or three-year term. This can result in significant cost savings compared to on-demand pricing, especially for long-running workloads.

Implement auto-pause and auto-scale

Azure SQL databases can be configured to pause during periods of inactivity automatically and automatically scale up or down based on workload demands. This allows you to pay only for the needed resources, reducing costs during idle periods.

Use serverless options

Azure SQL Database serverless is cost-effective for sporadic or unpredictable workloads. It automatically scales compute resources based on demand and charges you based on the actual compute used per second.

Optimize data storage

Evaluate the data storage requirements of your Azure SQL databases. Remove any unnecessary data and implement data compression techniques to reduce storage costs. Additionally, consider using Azure Blob Storage for storing large, infrequently accessed data to save costs.

Implement query and index optimizations

Review and optimize your database queries to reduce resource consumption. Ensure that appropriate indexes are in place to improve query performance and reduce the need for excessive computing resources.

Consider database consolidation

If you have multiple databases with low utilization, consider consolidating them into fewer databases to save costs. However, be mindful of performance considerations and ensure that consolidation does not impact your application’s performance.

Additionally, the Cost Analyzer can clone views and compare them. The comparison view allows you to select two different time ranges for cost analysis. You can utilize the Table chart type to ascertain the cost differences of your databases between these time ranges. The analysis also allows you to monitor a specific view of your desired time range.

Monitoring in Turbo360 Cost Analyzer

Gain visibility into the Azure cost trend and set up monitoring with proactive alerts to manage and mitigate the potential spikes in your Azure cost. In Cost Analyzer’s monitoring, you can create monitors with specific intervals and define rules based on the needed subscriptions and filters.

Keep track of the cost of your SQL Database and get notified whenever the spending exceeds a particular budget. The Budget section within the rule configuration provides a cost trend for the selected database, based on which you can define a budget for your rule. Alternatively, you can configure the budget difference based on the trend of cost differences.

Monitoring in Turbo360 Cost Analyzer

To ensure timely notifications, you can configure recipients and choose notification channels to receive alerts whenever your SQL database cost exceeds the predefined budget. This allows you to investigate the cause of increased expenses immediately. Utilize the calendar view that provides a historical summary of alert statuses, pinpointing the precise date and time of cost spikes.
