The cheapest Azure database depends on what you mean by “database.”
If you mean the lowest possible ongoing cost for a small relational application, Azure SQL Database can be extremely inexpensive because Microsoft currently offers a free Azure SQL Database offer with up to 10 General Purpose databases per subscription. Each eligible database includes 100,000 vCore seconds of serverless compute, 32 GB of data storage, and 32 GB of backup storage per month. The free offer has no time limit, subject to its monthly limits. (Microsoft Learn)
If you mean the cheapest standard paid managed database with continuously available compute, Azure Database for MySQL Flexible Server has a particularly low-cost Burstable option. Microsoft’s current India pricing page lists a B1s configuration with 1 vCore and 1 GiB of memory at approximately $6.205 per month on pay as you go, before applicable storage, backup, networking, taxes, and other charges. A B1ms configuration with 1 vCore and 2 GiB is listed at approximately $12.41 per month. (Microsoft Azure)
If you need PostgreSQL, Azure Database for PostgreSQL Flexible Server has a B1ms Burstable configuration listed at approximately $12.41 per month before storage, backup, networking, and other applicable charges. It also supports Stop/Start, meaning compute charges can be eliminated while the server is stopped, leaving storage and applicable backup costs. (Microsoft Azure)
If you need a NoSQL database with unpredictable or intermittent traffic, Azure Cosmos DB Serverless can be attractive because it bills according to request-unit consumption and storage without a provisioned-throughput minimum. Microsoft specifically describes the serverless model as suitable for low-traffic and intermittent workloads. (Microsoft Azure)
Therefore, there is no universally cheapest Azure database.
The practical answer is:
The most important lesson is that the database service with the lowest advertised compute price is not necessarily the database with the lowest total cost of ownership.
Azure has several database technologies, purchasing models, service tiers, deployment options, and billing dimensions.
Two databases that appear similar can have very different monthly bills because of:
This means asking “What is the cheapest Azure database?” without describing the workload is similar to asking “What is the cheapest car?”
A compact city car may be cheapest for commuting.
A larger vehicle could be cheaper for moving equipment.
An electric vehicle might have a higher purchase price but lower operating expenses.
The same principle applies to Azure databases.
A database that looks inexpensive per hour can become expensive if it requires permanent compute, high I/O, backups, replication, and substantial data transfer.
Conversely, a service with a higher unit price can be cheaper for a small application if it allows you to pay only when the application actually uses it.
Before comparing Azure database products, it is important to understand the major Azure billing models.
Provisioned databases have a defined compute capacity.
You select resources such as:
The database generally continues running whether the application is busy or idle.
This model is often appropriate for:
The advantage is predictable performance.
The disadvantage is that you can pay for capacity even when application traffic is low.
Serverless changes the economics.
Instead of paying for a fixed amount of compute continuously, the platform can dynamically allocate compute according to demand.
Azure SQL Database serverless, for example, bills compute on a per-second basis according to actual resource usage, subject to minimum compute while the database is online. When the database is paused, compute charges stop and storage-related charges remain. (Microsoft Azure)
This can be particularly attractive for:
Serverless is not automatically cheaper.
If your database is busy most of the day, provisioned compute can be more economical.
Some cloud databases use a consumption model.
Azure Cosmos DB Serverless is an important example.
Instead of maintaining provisioned throughput, serverless Cosmos DB charges according to request-unit consumption and storage. Microsoft states that serverless has no minimum operations or request units and is designed for workloads with low or intermittent traffic. (Microsoft Azure)
This can be powerful for applications where traffic is:
However, a request-based model can become expensive if the application performs large numbers of database operations continuously.
Compute is only one part of database pricing.
You may also pay for:
For example, Azure Database for PostgreSQL Flexible Server separates compute, storage, and backup charges. Microsoft explains that compute is billed per vCore-hour, while storage and applicable backup storage are billed per GiB-month. (Microsoft Azure)
This is why comparing only compute prices can produce misleading conclusions.
Azure SQL Database deserves special attention because of Microsoft’s current free offer.
The free offer provides up to 10 General Purpose Azure SQL databases per subscription, with each database receiving monthly allowances of:
The free offer is not merely a trial that expires after a short period. Microsoft currently describes it as free indefinitely within the applicable monthly limits. (Microsoft Learn)
That makes Azure SQL Database one of the most compelling choices for:
For eligible workloads, the answer to “Which Azure database is the cheapest?” can therefore simply be:
Azure SQL Database can be free.
But there are important conditions.
The free database offer is based on monthly consumption limits.
Microsoft currently specifies:
Once the applicable free allowance is exhausted, additional usage depends on the billing choice and configuration. Microsoft also provides an option to stop the database until the next month when the free allowance is exhausted. (Microsoft Learn)
This makes monitoring important.
A database that is technically “free” can still become a billing concern if the application exceeds its included limits and is configured to continue consuming paid resources.
Azure SQL Database serverless is specifically designed for databases with variable or intermittent utilization.
Microsoft states that serverless compute can automatically scale based on workload and bill compute per second. It can also automatically pause after inactivity, depending on the configuration. (Microsoft Azure)
Imagine a small business application used mainly from 9 AM to 6 PM.
During the night, the database may have almost no activity.
With conventional provisioned compute, the database can continue consuming compute capacity.
With serverless, the database can reduce compute consumption and eventually pause when the configured inactivity period is reached.
That can materially change the monthly economics.
This distinction is important.
Suppose you have:
A serverless database that remains active almost continuously may not provide the cost advantage you expect.
Microsoft explicitly notes that provisioned compute can be less expensive for databases with more uniform and substantial compute utilization. (Microsoft Azure)
Therefore:
Intermittent workload + serverless = potentially excellent economics.
Constant workload + provisioned compute = often better economics.
Azure Database for MySQL Flexible Server is another strong candidate when cost is the priority.
Microsoft currently lists a Burstable B1s configuration with:
The B1ms configuration provides:
These figures are based on the pricing currently displayed on Microsoft’s India pricing page and should be treated as indicative rather than universal. Actual pricing depends on region, agreement, currency, configuration, and additional resources. (Microsoft Azure)
MySQL is widely used for:
If your application already uses MySQL, moving to another database merely because its headline price is lower can create development and migration costs.
The cheapest database is often the one that meets your requirements with the least operational and application change.
Azure Database for MySQL Flexible Server includes Burstable compute configurations designed for workloads with flexible compute requirements.
This makes them particularly relevant for:
The B1s option is especially notable because of its low advertised compute price. (Microsoft Azure)
But remember that the monthly compute figure is not necessarily the final Azure invoice.
You may also have:
For PostgreSQL workloads, Azure Database for PostgreSQL Flexible Server is generally the obvious managed Azure choice.
Microsoft’s current pricing page lists the B1ms Burstable configuration at approximately $12.41 per month on pay as you go. (Microsoft Azure)
PostgreSQL Flexible Server is designed to provide:
Microsoft specifically highlights Stop/Start as a cost optimization capability because compute charges stop while the server is stopped, leaving storage and applicable backup costs. (Microsoft Azure)
Consider a development database used by a team only during working hours.
If it runs continuously for 24 hours a day, the organization pays for compute throughout the day.
If the team works approximately eight hours a day and the database can be stopped outside those hours, compute consumption can be substantially reduced.
The exact savings depend on the configuration and operational schedule.
This is one of the most practical ways to reduce the cost of a managed PostgreSQL database on Azure.
Azure Cosmos DB is fundamentally different from traditional relational database services.
It is a globally distributed NoSQL database platform supporting multiple APIs and data models.
Its Serverless model is especially relevant when discussing the cheapest Azure database.
Microsoft describes Cosmos DB Serverless as a pay-per-request model with no minimum operations or provisioned request units. It is intended for low-traffic applications and intermittent workloads. (Microsoft Azure)
That makes it potentially attractive when:
Suppose you have an application that receives:
Provisioning a constant throughput level may result in paying for capacity you do not use.
Serverless allows consumption to track actual database operations more closely.
This is one reason there is no single “cheapest Azure database.”
The correct answer depends on how the application behaves.
Cosmos DB also has a free-tier option.
Microsoft currently states that the free tier provides the first:
for the lifetime of one Azure Cosmos DB account per Azure subscription, when the free tier is enabled on a new account. (Microsoft Azure)
This can make Cosmos DB highly attractive for development and small workloads.
However, the free tier and serverless model are not identical.
Microsoft notes that the free tier does not apply to serverless. (Microsoft Azure)
Therefore, you should select the billing model based on workload characteristics rather than assuming that “Cosmos DB free tier” and “Cosmos DB serverless” are interchangeable.
The following comparison is more useful than simply asking which service has the lowest advertised hourly rate.
| Azure database option | Best cost scenario | Typical reason to choose it |
| Azure SQL Database Free Offer | Small eligible relational workloads | Free monthly allowance |
| Azure SQL Database Serverless | Intermittent SQL workloads | Per-second compute and auto-pause |
| Azure Database for MySQL Flexible Server B1s | Small MySQL applications | Very low burstable compute price |
| Azure Database for MySQL Flexible Server B1ms | Small applications needing more memory | Low-cost managed MySQL |
| Azure Database for PostgreSQL Flexible Server B1ms | Small PostgreSQL workloads | Low-cost managed PostgreSQL |
| Azure Cosmos DB Serverless | Low-volume NoSQL workloads | Pay for consumed operations |
| Azure Cosmos DB Free Tier | Small provisioned NoSQL workloads | Free throughput and storage allowance |
| Provisioned Azure SQL Database | Consistent workloads | Predictable performance |
| PostgreSQL Flexible Server with Stop/Start | Non-production workloads | No compute billing while stopped |
| MySQL Flexible Server | Small to medium MySQL systems | Managed MySQL with flexible scaling |
The important point is that these are not interchangeable database technologies.
For a startup, the cheapest Azure database depends on the application’s architecture.
A startup with a conventional relational application might choose:
Azure SQL Database Free Offer
if the workload fits its limits.
A startup using Laravel, WordPress, or another MySQL-based platform might prefer:
Azure Database for MySQL Flexible Server
because compatibility and migration simplicity can outweigh small price differences.
A startup building a PostgreSQL-based application might choose:
Azure Database for PostgreSQL Flexible Server
because PostgreSQL is already part of its application architecture.
A startup developing an event-driven or document-oriented application may consider:
Azure Cosmos DB Serverless
when its request pattern makes consumption-based billing economical.
Development environments are often the easiest place to reduce database costs.
Developers frequently leave resources running when nobody is using them.
That creates unnecessary cloud expenditure.
For development databases, consider:
The right option depends on what the development environment is intended to reproduce.
Testing has different requirements from development.
Some automated tests may require:
Other tests may only need:
Cloud database costs can therefore be reduced by matching the test environment to the actual testing objective.
Do not automatically run a production-sized database for unit tests.
For a small website, there are several possible answers.
MySQL Flexible Server is a natural candidate.
The current Azure India pricing page shows a B1s Burstable option at approximately $6.205 per month for compute before other charges. (Microsoft Azure)
Azure SQL Database may be the better fit.
If the workload is small and eligible, the free Azure SQL Database offer can be particularly compelling. (Microsoft Learn)
PostgreSQL Flexible Server is the obvious managed PostgreSQL choice.
Cosmos DB Serverless may be worth evaluating when database operations are low and intermittent.
Ecommerce workloads deserve more caution.
An ecommerce database commonly stores:
Relational integrity is often important.
That makes SQL Server, MySQL, or PostgreSQL suitable depending on the application’s architecture.
Cost should not be the only selection criterion.
A database failure can cost considerably more than the monthly database bill.
For ecommerce, evaluate:
Choosing the absolute cheapest SKU can be a false economy.
SaaS products introduce another variable: tenant growth.
At the beginning, a SaaS product may have:
Later, it might have:
A database architecture that is inexpensive at launch may become inefficient at scale.
Therefore, SaaS teams should optimize for:
low initial cost + predictable scaling + manageable operational complexity.
Azure SQL Database serverless can be attractive for early-stage applications with intermittent activity.
PostgreSQL Flexible Server can be attractive for teams that need PostgreSQL compatibility.
MySQL Flexible Server can be appropriate for MySQL-based SaaS systems.
Cosmos DB can be valuable when the application’s data model and access patterns fit a distributed NoSQL architecture.
For a personal project, the Azure SQL Database free offer is particularly interesting if the application fits SQL Server requirements and the free allowance. Microsoft currently provides up to 10 eligible free databases per subscription, subject to the stated limits. (Microsoft Learn)
This can be useful for:
Another option is Cosmos DB’s free tier, which provides a free allowance for provisioned throughput and storage on an eligible new account. (Microsoft Azure)
Students should focus on minimizing both direct cost and operational complexity.
A free Azure SQL Database allowance can be useful for learning relational database concepts.
Students learning PostgreSQL can use PostgreSQL Flexible Server and stop the server when it is not needed.
Students learning MySQL can similarly use a low-cost Burstable MySQL Flexible Server.
Students learning NoSQL can explore Cosmos DB’s free tier or emulator.
The best choice is therefore strongly related to the technology the student wants to learn.
For a small REST API, the database does not necessarily need substantial capacity.
A typical low-traffic API might require:
Possible choices include:
For a relational API, Azure SQL serverless is particularly attractive when periods of inactivity are common. Microsoft specifically positions serverless for variable usage and intermittent workloads. (Microsoft Azure)
A database bill can be broken into multiple dimensions.
Compute is usually the most obvious cost.
It can be measured through:
Storage charges may apply based on:
Managed databases generally provide backup functionality, but backup storage beyond included allowances or configured retention can create additional costs.
Some database platforms charge for I/O or include certain I/O capabilities within the service tier.
This matters particularly when applications perform:
Moving data out of Azure can result in networking charges.
Microsoft’s PostgreSQL pricing documentation explicitly notes that standard networking charges apply for network egress. (Microsoft Azure)
Therefore, a database located in Azure can still generate networking costs if applications or users consume data across applicable network boundaries.
Suppose Database A costs $7 per month.
Database B costs $12 per month.
At first glance, Database A appears better.
But if your application is written specifically for PostgreSQL, using Database A might require:
If those activities cost hundreds or thousands of dollars, saving $5 per month is meaningless.
This leads to an important cloud-finance principle:
Optimize total cost, not just database SKU price.
Total cost of ownership includes more than the Azure invoice.
A useful framework is:
TCO = infrastructure cost + operations cost + development cost + migration cost + downtime risk + scaling cost
Each component matters.
This includes:
Managed databases reduce operational responsibilities.
You still need:
But Azure manages significant portions of the underlying infrastructure.
The database must integrate with:
Compatibility matters.
Moving from one database technology to another can be expensive.
Migration may involve:
Because your Azure subscription may be billed in India, regional pricing deserves special attention.
Microsoft’s Azure pricing pages allow customers to select region and currency, and Microsoft states that displayed prices are estimates rather than formal quotations. Pricing can vary according to agreement, purchase date, currency conversion, and other factors. (Microsoft Azure)
For that reason, never publish an Azure database price as if it were a permanent worldwide price.
Instead, describe it as:
This is particularly important for SEO content because cloud pricing changes.
Selecting the cheapest service is only the first step.
The biggest savings often come from optimizing how the database is used.
Do not automatically select a large production tier.
Start with measured requirements.
Monitor:
Then scale according to evidence.
Azure SQL serverless can be a strong cost-saving mechanism for variable workloads.
It bills compute according to usage and can pause during inactivity when configured appropriately. (Microsoft Azure)
PostgreSQL Flexible Server supports Stop/Start.
When stopped, compute billing stops, while applicable storage and backup charges remain. (Microsoft Azure)
This can be highly effective for:
Burstable compute is designed for workloads that do not require sustained maximum CPU performance.
It can be particularly useful for:
Database storage can grow silently.
Implement:
Poor SQL can increase resource consumption.
Examples include:
Improving a query can sometimes save more money than changing database SKUs.
This is one of the most useful comparisons.
Best when:
The free offer makes it exceptionally attractive for qualifying small workloads. (Microsoft Learn)
Best when:
The B1s configuration currently listed by Microsoft is approximately $6.205 per month for compute in the relevant pricing view. (Microsoft Azure)
Azure SQL is usually attractive to Microsoft-centric application stacks.
PostgreSQL Flexible Server is attractive for open-source PostgreSQL applications.
Choose PostgreSQL when you need:
Choose Azure SQL when you need:
Cost should be evaluated only after technical compatibility is established.
MySQL and PostgreSQL can both be cost-effective.
The difference is often less about the raw database engine and more about:
If the application already uses MySQL, changing to PostgreSQL purely to save a small monthly amount usually does not make financial sense.
Likewise, a PostgreSQL application should not be migrated to MySQL simply because one SKU looks cheaper.
Cosmos DB can be cost-effective for the right workload, but it should not be considered a direct replacement for SQL databases.
Cosmos DB is designed around distributed NoSQL access patterns.
Relational databases provide:
Cosmos DB offers a different model.
Therefore, choosing Cosmos DB solely because it can be cheap under light traffic can create architectural problems if the application fundamentally requires relational behavior.
Cosmos DB Serverless becomes particularly interesting when:
Microsoft specifically identifies low-traffic and intermittent workloads as suitable for Cosmos DB Serverless. (Microsoft Azure)
Azure SQL is particularly attractive when:
The free offer can significantly change the economics of small applications. (Microsoft Learn)
MySQL Flexible Server is compelling when:
The currently listed B1s compute price is approximately $6.205 per month in the relevant Microsoft pricing view. (Microsoft Azure)
PostgreSQL Flexible Server is attractive when:
Microsoft currently lists B1ms Burstable compute at approximately $12.41 per month in the relevant pricing view. (Microsoft Azure)
Azure Database for MariaDB should not automatically be considered when starting a new architecture.
Microsoft’s Azure database portfolio and service lifecycle should always be checked before committing to a database technology.
For new projects, organizations should generally prioritize currently supported, actively developed Azure database offerings rather than selecting a platform simply because it appears inexpensive.
The key lesson is:
Never optimize price before verifying service lifecycle and support status.
Azure SQL Managed Instance is powerful but generally not the first choice when the objective is the lowest database cost.
It is designed for workloads requiring broader SQL Server compatibility and instance-level capabilities.
It can make sense when you need:
But for a tiny application, it is usually unnecessary complexity and cost.
You can theoretically run PostgreSQL on Azure compute.
That may reduce the database service premium.
However, you become responsible for more operational work, including:
A self-managed database may have a lower infrastructure bill while having a higher operational cost.
This is why managed database pricing should not be compared directly with raw virtual machine pricing without accounting for labor.
For qualifying use under Microsoft’s current free offer, Azure SQL Database can be free within the monthly limits.
The current offer provides:
Microsoft says the free database offer has no time limit, provided usage stays within the monthly allowances and applicable conditions. (Microsoft Learn)
However, “free” does not mean unlimited.
If your application requires more compute, storage, or backup capacity, additional charges can apply depending on your configuration.
100,000 vCore seconds is approximately:
27.78 vCore-hours
That is an important figure when evaluating the free offer.
For example, a continuously active 1-vCore workload for approximately 27.78 hours would consume around 27.78 vCore-hours.
The actual Azure SQL serverless billing calculation is more nuanced because billing depends on resource usage and the configured minimum compute capacity. Microsoft explains that the billed compute can depend on CPU or memory consumption, with minimum compute resources applying while the database is online. (Microsoft Azure)
Therefore, developers should monitor actual consumption instead of assuming that the free allowance corresponds directly to a fixed number of hours.
Practical steps include:
Microsoft specifically recommends monitoring remaining free vCore seconds and notes that open connections from tools such as SQL Server Management Studio can continue consuming resources by preventing auto-pause. (Microsoft Learn)

A $6 database is not necessarily a $6 monthly bill.
Always consider:
A cheap database that cannot efficiently support your application is not cheap.
If a database is used only a few hours per day, serverless or Stop/Start may dramatically improve economics.
Development databases should not automatically use production-level capacity.
A low-cost SKU can become expensive if the application outgrows it and requires major redesign.
A familiar database can be cheaper overall even if its infrastructure price is slightly higher.
Backup retention can increase the total bill.
Applications that move significant data across networks can incur additional charges.
A simple model is:
Monthly Database Cost = Compute + Storage + Backup + I/O or Requests + Networking + HA/Replication + Other Applicable Charges
For provisioned databases:
Compute Cost = hourly compute price × hours used
For consumption-oriented databases:
Consumption Cost = actual database operations × applicable unit price
For serverless databases:
Compute Cost = billed compute consumption × applicable rate
plus storage and other charges.
The exact formula depends on the service.
Imagine a small application with:
If it qualifies for the current Azure SQL Database free offer, the database can remain within the free allowance.
This makes Azure SQL potentially unbeatable on price for that particular scenario.
Imagine a small MySQL application requiring:
Microsoft’s current pricing page lists B1s Burstable compute at approximately $6.205 per month before other applicable costs. (Microsoft Azure)
If the application needs more memory, B1ms is listed at approximately $12.41 per month.
This can be an attractive option for lightweight MySQL workloads.
Suppose a PostgreSQL application requires:
The B1ms PostgreSQL Flexible Server configuration is currently listed at approximately $12.41 per month in Microsoft’s pricing view. (Microsoft Azure)
If this is a development environment, Stop/Start can further reduce compute consumption.
Suppose an application receives unpredictable requests and has long periods of inactivity.
Instead of provisioning constant throughput, Cosmos DB Serverless may allow the application to pay according to actual request-unit consumption and storage.
Microsoft specifically positions Serverless for low-traffic and intermittent workloads. (Microsoft Azure)
This can make it more economical than a continuously provisioned database for the right access pattern.
Azure pricing varies by:
The same database configuration can have different pricing in different Azure regions.
Therefore, always check the Azure pricing page or Azure Pricing Calculator using your actual:
Microsoft explicitly warns that pricing displayed on its database pricing pages is an estimate and that actual prices can vary according to agreement, purchase date, currency exchange rates, and other factors. (Microsoft Azure)
If a database runs continuously, pricing optimization does not stop at choosing a cheap SKU.
Azure provides purchasing options that can reduce long-term costs.
For example, Microsoft currently describes savings plans for databases and reservations as mechanisms for reducing costs when customers make qualifying commitments. PostgreSQL Flexible Server pricing documentation also describes discounts associated with longer-term commitments. (Microsoft Azure)
However, commitments should only be purchased after the workload is understood.
Do not reserve a resource simply because a discount appears attractive.
A savings plan can make sense when:
It may be inappropriate for:
Reservations can be useful when:
Again, the cheapest database configuration today may not be the cheapest long-term architecture.
For production systems, “cheapest” should be interpreted as:
lowest sustainable cost while meeting reliability, performance, security, backup, and availability requirements.
That definition changes everything.
A production ecommerce database may require:
The absolute smallest database may be inappropriate.
High availability introduces additional infrastructure considerations.
Depending on the service, you may need:
These features can increase costs.
The right approach is to determine the business’s actual availability requirement.
A personal project may tolerate downtime.
A payment platform may not.
A development environment may not need zone redundancy.
A mission-critical application may.
For ordinary business applications, the decision often comes down to:
Azure SQL Database is especially compelling for Microsoft-centric organizations.
PostgreSQL Flexible Server is compelling for organizations using PostgreSQL.
MySQL Flexible Server is compelling for MySQL-based applications.
Cosmos DB is compelling for applications that genuinely need its NoSQL and distributed capabilities.

Azure SQL can be the cheapest option for a qualifying small relational workload because of Microsoft’s current free offer.
But MySQL Flexible Server has very low Burstable compute pricing.
PostgreSQL Flexible Server can be inexpensive for PostgreSQL workloads and offers Stop/Start.
Cosmos DB Serverless can be economical for intermittent NoSQL workloads.
Therefore, the correct answer depends on workload type.
Azure SQL Database Free Offer

Azure Cosmos DB Serverless
Azure Cosmos DB Free Tier
Azure SQL Database Serverless
PostgreSQL Flexible Server with Stop/Start
There is no single cheapest database for every workload. For eligible small relational workloads, Azure SQL Database can currently be free within Microsoft’s monthly free allowance. MySQL Flexible Server has very low-cost Burstable configurations, while Cosmos DB Serverless can be economical for low-volume NoSQL workloads. (Microsoft Learn)
Microsoft currently offers an Azure SQL Database free offer with up to 10 General Purpose databases per subscription. Each database includes 100,000 vCore seconds, 32 GB of data storage, and 32 GB of backup storage per month under the offer. (Microsoft Learn)
Yes. Azure Database for MySQL Flexible Server has low-cost Burstable configurations. Microsoft’s current pricing page lists B1s at approximately $6.205 per month for compute in the relevant pricing view, before other applicable charges. (Microsoft Azure)
It can be. PostgreSQL Flexible Server includes Burstable configurations, and Microsoft’s current pricing page lists B1ms at approximately $12.41 per month in the relevant pricing view. Stop/Start can also eliminate compute charges while the server is stopped. (Microsoft Azure)
Not universally. Cosmos DB Serverless can be cheaper for low-volume, intermittent NoSQL workloads, while Azure SQL can be substantially more economical for relational workloads, particularly when the Azure SQL free offer applies. (Microsoft Azure)
For a SQL Server-based application, Azure SQL Database may be the most economical, especially if the workload fits the free offer. For a MySQL website, MySQL Flexible Server is a natural low-cost choice. For PostgreSQL, PostgreSQL Flexible Server is appropriate.
For a managed Azure database, MySQL Flexible Server is generally the natural choice because WordPress commonly uses MySQL-compatible relational databases. A low-cost Burstable configuration can be appropriate for a small site.
Azure SQL Database is often the natural choice for .NET applications using Microsoft SQL Server technologies. For very small workloads, the current Azure SQL free offer can make it particularly attractive.
Azure Database for PostgreSQL Flexible Server is the managed Azure PostgreSQL option to evaluate first. The Burstable B1ms configuration is currently listed at approximately $12.41 per month before other applicable costs. (Microsoft Azure)
Azure Database for MySQL Flexible Server has a B1s Burstable configuration currently listed at approximately $6.205 per month for compute in the relevant pricing view. (Microsoft Azure)
The answer depends on workload and architecture. Azure Cosmos DB Serverless can be particularly attractive for low-volume and intermittent NoSQL workloads because it bills based on consumed operations and storage without a provisioned throughput minimum. (Microsoft Azure)
Yes, certain Azure database offers can be used within their applicable free limits. Azure SQL Database currently has a free offer with monthly limits, and Cosmos DB has a free tier with applicable throughput and storage allowances. (Microsoft Learn)
Microsoft currently states that the Azure SQL Database free offer is free indefinitely, subject to the monthly usage limits and applicable conditions. (Microsoft Learn)
It depends on workload. Serverless is generally suited to variable and intermittent workloads. Microsoft notes that provisioned compute can be less expensive for databases with consistently high utilization. (Microsoft Azure)
No. Pricing depends on region, configuration, billing model, currency, agreement, and other factors. Microsoft’s pricing pages describe displayed prices as estimates rather than formal quotations. (Microsoft Azure)
Yes. Azure Database for PostgreSQL Flexible Server supports Stop/Start. Microsoft states that when the server is stopped, compute charges stop, while applicable storage and backup charges continue. (Microsoft Azure)
Microsoft describes Cosmos DB Serverless as having no minimum operations or request units, with billing based on consumed database operations and storage. (Microsoft Azure)
If the question is asking for one universal answer, the most accurate response is:
There is no universally cheapest Azure database.
However, the current Azure pricing landscape makes several options stand out.
For an eligible small relational workload, Azure SQL Database can be the cheapest because Microsoft currently provides a free offer with monthly compute, storage, and backup allowances. (Microsoft Learn)
For a small MySQL application that needs a continuously available managed database, Azure Database for MySQL Flexible Server Burstable is one of the lowest-cost conventional managed database options, with Microsoft’s current pricing page listing B1s compute at approximately $6.205 per month before additional charges. (Microsoft Azure)
For PostgreSQL, Azure Database for PostgreSQL Flexible Server Burstable provides a low-cost managed PostgreSQL option, while Stop/Start can further reduce compute costs for non-production workloads. (Microsoft Azure)
For intermittent NoSQL applications, Azure Cosmos DB Serverless can be highly cost-effective because it charges based on consumed operations and storage rather than requiring provisioned throughput. (Microsoft Azure)
The best cost-saving strategy is therefore not simply to search for the lowest price displayed on an Azure pricing page.
Instead:
For most small projects, the strongest starting point is Azure SQL Database Free Offer for qualifying relational applications, MySQL Flexible Server Burstable for MySQL applications, PostgreSQL Flexible Server Burstable for PostgreSQL applications, and Cosmos DB Serverless for genuinely intermittent NoSQL workloads.
The cheapest Azure database is ultimately the one that delivers the required functionality and reliability with the lowest total cost of ownership, not necessarily the one with the smallest advertised compute number.
