Azure SQL Cost Management and Optimization Guide

Managing costs in Azure SQL is a crucial aspect of database administration.

To minimize costs, Azure SQL offers a reserved instance pricing model, which can reduce costs by up to 33% compared to pay-as-you-go pricing.

Properly sizing your database is essential for cost optimization.

A database with a large data volume but low usage might be a good candidate for a reserved instance, where you pay a fixed fee for a committed usage level.

Regularly monitoring your database's performance and adjusting your pricing plan accordingly is key to cost management.

Azure SQL provides features like automatic tuning and query performance insights to help you identify areas for improvement.

To get a clear picture of the costs involved with Azure SQL Database, you can use the Azure pricing calculator to estimate costs for different configurations. This tool allows you to add Azure resources and review estimated costs.

You can also estimate how different Retention Policy options affect cost, and explore the vCore-based and DTU-based purchasing models to compare pricing. For example purposes, you can refer to the Azure SQL Database pricing calculator example for storage.

To get the most out of the pricing calculator, be sure to commit to a reservation for compute resources for one to three years to save money. This can help you scale resources up or down to control costs based on your application needs.

To plan and manage costs for Azure SQL Database, you can start by using the Azure pricing calculator to add Azure resources and review the estimated costs. This will give you a clear understanding of the costs associated with your Azure SQL Database resources.

You can also use Cost Management features to set budgets and monitor costs. This will help you stay on top of your spending and make adjustments as needed.

One way to reduce costs is to scale resources up or down to control costs based on your application needs. You can also save money by committing to a reservation for compute resources for one to three years.

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

You can also use the Azure pricing calculator to estimate costs for different Azure SQL Database configurations.

Here are the different service tiers for single databases:

Outbound data transfers are charged at regular data transfer rates.

Azure SQL Database is billed on a predictable, hourly rate, unless you're using serverless options, which charges you based on the actual compute used per second.

In the vCore purchasing model, you can choose between a provisioned compute tier, billed per hour, and a serverless compute tier, billed per second. The way you get charged for each compute tier varies, so it's essential to understand what works best for your workload when planning and considering costs.

The SQL Database serverless compute tier optimizes price-performance and simplifies performance management for single databases with intermittent, unpredictable usage by auto-scaling compute and billing for compute used per second.

The Azure Hybrid Benefit is a cost-saving option that can reduce your Azure SQL costs by up to 55%. This benefit is available to all vCore-based options: SQL Database Managed Instance, Single Database, and Elastic Pool.

You can use your existing SQL Server licenses with active Software Assurance to pay a reduced rate, known as the base rate, on SQL Database. This means you can save money by leveraging your existing licensing investments.

To be eligible for the Azure Hybrid Benefit, you need to have active Software Assurance on your SQL Server licenses. You can activate the benefit via the Azure Portal by attesting that you have sufficient active licenses with Software Assurance.

The virtualization benefit is also available with the Azure Hybrid Benefit. You can convert 1 license core of SQL Enterprise Edition with active Software Assurance to get up to 4 vCores of General Purpose or Hyperscale tier at the base rate. This makes moving virtualized applications to vCore-based SQL Database options highly cost-effective.

Here's a quick rundown of the virtualization benefit:

Keep in mind that you can't use your SQL Server licenses on-premises and in the cloud at the same time, except during a 180-day grace period to facilitate migration. Also, the Azure Hybrid Benefit cannot be applied retroactively, so make sure to activate it before switching to Azure SQL Database.

Azure SQL Database offers two main purchasing models: vCore and DTU. These models have different pricing structures, so it's essential to choose the one that best fits your workload.

You can exchange existing licenses for discounted rates in the provisioned compute tier of the vCore-based purchasing model. This is made possible through the Azure Hybrid Benefit (AHB).

The vCore-based purchasing model gives you the flexibility to choose between a provisioned compute tier, billed per hour, and a serverless compute tier, billed per second. You can also select the hardware configuration.

The DTU-based purchasing model offers a straightforward approach to provisioning and managing compute resources, with three service tiers: Basic, Standard, and Premium. Pricing is determined by the selected tier and the number of DTUs allocated to the database.

You can save money by committing to a reservation for compute resources for one to three years.

Azure SQL Database offers two purchasing models: DTU and vCore. The DTU purchasing model is 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.

The Basic tier has 5 DTUs, 2 GB of included storage, and a max storage of 2 GB, priced at $0.0068 per hour. The Standard tier has varying DTUs, included storage, and max storage, priced at different hourly rates.

For example, the S0 tier has 10 DTUs, 250 GB of included storage, and a max storage of 250 GB, priced at $0.0202 per hour. The Premium tier also has varying DTUs, included storage, and max storage, priced at different hourly rates.

In the DTU purchasing model, an initial set of storage for data and backups is provided at no additional cost. The size of the storage depends on the service tier selected. Extra data storage can be purchased in the standard and premium tiers.

Azure SQL Database also offers a way to manage and reduce costs by scaling resources up or down to control costs based on your application needs. You can save money by committing to a reservation for compute resources for one to three years.

Choosing the right hardware type is crucial to optimizing your Azure spend. The vCore purchase model offers four different hardware types, each with its own unique characteristics.

The Gen 5 hardware type is a good all-around option, providing a balance between compute and memory resources. It's suitable for most data workloads that don't require higher memory or CPU.

The Fsv2-series is a compute-optimized option, delivering lower CPU latency and higher clock speeds. This makes it ideal for compute-intensive data workloads.

The M-series is memory-optimized, offering 29 GB per vCore, which is eight times more memory than the Gen 5. This makes it a great option for workloads that require a lot of memory.

The DC-series is ideal for secure workloads, using Intel processors with Software Guard Extension technology. It also offers a balance between compute and memory, similar to the Gen 5.

Here's a summary of the four hardware types and their prices per hour:

It's worth noting that the prices can vary significantly depending on the hardware type and vCore option chosen.

Optimizing resource utilization is crucial to reducing Azure SQL costs. Regularly monitor your Azure SQL databases' performance and resource utilization to identify underutilized or overprovisioned resources. This can be done using Azure Monitor and Azure SQL Analytics.

You can also implement auto-pause and auto-scale to pause your databases during periods of inactivity 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.

By regularly analyzing resource usage, you can make necessary adjustments to optimize costs. Consider using Azure SQL Database serverless, which automatically scales compute resources based on demand and charges you based on the actual compute used per second.

When planning and considering costs, it's essential to understand the difference between provisioned and serverless compute tiers.

Azure SQL Database supports two types of compute tiers: provisioned throughput and serverless. The way you get charged for each compute tier varies.

Provisioned compute is ideal for single databases and elastic pools with regular usage that cannot afford any delay in compute warm-up after idle usage periods.

Provisioned compute resources are provisioned in virtual cores (vCores) with an option to choose between compute generations.

In the vCore model, you can choose from various vCore sizes, ranging from 2 to 128 vCores, with corresponding memory sizes. For example, a 4 vCore instance comes with 20.4 GB of memory.

Here's a list of vCore sizes and their corresponding memory sizes:

On the other hand, serverless compute is ideal for sporadic or unpredictable workloads. It automatically scales compute resources based on demand and charges you based on the actual compute used per second.

Regularly monitoring your Azure SQL databases' performance and resource utilization is crucial to optimize costs. This helps identify underutilized or overprovisioned resources, allowing you to make necessary adjustments.

Azure Monitor and Azure SQL Analytics can provide valuable insights into resource utilization, enabling you to make informed decisions. By regularly monitoring your database's performance, you can identify areas where resources are being wasted.

To optimize resource utilization, consider implementing auto-pause and auto-scale features in Azure SQL databases. This allows you to pause the database during periods of inactivity and automatically scale up or down based on workload demands, reducing costs during idle periods.

The right-sizing feature in Turbo360 Cost Analyzer can help you analyze resource usage and provide recommendations to downsize or upgrade resources, reducing unnecessary cost expenses.

By monitoring and optimizing resource utilization, you can significantly reduce costs and improve the efficiency of your Azure SQL databases.

Exporting your cost data is a great way to retrieve datasets for further analysis. You can export your costs on a daily, weekly, or monthly schedule and set a custom date range.

Exporting cost data is the recommended way to retrieve cost datasets. This is especially helpful for finance teams who want to analyze the data using Excel or Power BI.

Exporting your cost data to a storage account is a convenient option. It allows you to access your data from anywhere and at any time.

The Hybrid Server Benefit offers a great way to maximize the value from your current licensing investments and accelerate your migration to the cloud. You can save up to 55% off the costs of running workloads in the cloud.

To be eligible, you need to have active Software Assurance on your SQL Server licenses. This benefit is available to all vCore-based options: SQL Database Managed Instance, Single Database, and Elastic Pool.

You can activate the Azure Hybrid Benefit via the Azure Portal by attesting you have sufficient active licenses with Software Assurance. The benefit works as follows: it's not available in the serverless compute tier of SQL Database.

The virtualization benefit is applicable to virtualized workloads on vCore-based Azure SQL Database. You can use it to convert 1 license core of SQL Enterprise Edition with active Software Assurance to get up to 4 vCores of General Purpose or Hyperscale tier at the base rate.

Here's an example of how this works: if you have 4 core licenses of SQL Enterprise Edition, you can receive up to 16 vCores of General Purpose at the base rate.

You have a 180-day grace period during which you can use licenses both on-premises and in the cloud to facilitate migration. This allows you to transition to the cloud at your own pace.

However, it's essential to note that Azure Hybrid Benefit cannot be applied retroactively. You'll need to activate it before you start using the benefit.

To effectively manage and reduce costs for Azure SQL Database, start by using the Azure pricing calculator to estimate costs. This tool helps you review the estimated costs of adding Azure resources.
