This article covers the top 9 serverless cloud databases on the market and their pros&cons. Plus, a bit of our experience and how we recommend selecting one.

Before starting with serverless databases, let's begin with a short recap of serverless computing. In a nutshell, it's a cloud computing model where developers focus on writing code without managing servers. In this paradigm, cloud providers dynamically handle server resources, automatically scaling them as needed, and bill customers based on actual usage.

It's cost-efficient, as you pay as you go, and amazingly scalable, as the system automatically tunes to handle varying workloads. And, of course, it reduces operational complexity, allowing developers to focus solely on delivering value. It offers a server-free development experience with tons of advantages.

And serverless databases further enhance this approach. They offer a database-as-a-service (DBaaS) model, allowing access to fully managed and scalable databases without addressing the underlying infrastructure.

Now, let's go deeper and explore the top databases for serverless applications on the market, their benefits, and key features.

Benefits of Using Serverless Databases for Modern Applications

But before we go into discussing separate serverless database systems and their providers, we want to walk you through a range of benefits that make them an ideal choice for modern application development.

Here are some of the key advantages of using serverless databases:

Auto-scaling and Geographical Distribution

No more worries about traffic spikes. Serverless databases automatically scale resources based on demand, ensuring seamless handling of fluctuating workloads. Whether your application experiences sudden surges in traffic or needs to accommodate growing data, serverless databases can quickly scale up or down to meet your requirements without any manual intervention.

Moreover, a serverless database also scales geographically, moving and storing your data worldwide to provide a better experience to your users across the globe.

Fully Managed Service

Serverless databases are managed by cloud providers, meaning there’s no need for your team to worry their heads about infrastructure maintenance, backups, or updates. This unties the hands of your developers to focus solely on building and improving applications, streamlining the development process, and reducing operational overhead.

Plus, have you seen their security precautions? Serverless databases ensure that every app that interacts with the same database goes through the same security access protocol. Meaning that it reduces the attack surface, taking that worry off your shoulders.


Serverless databases give you the ability to reduce latency. They are designed for high availability, ensuring data is accessible and protected from failures.

Cloud providers provide robust replication and redundancy mechanisms, ensuring data is stored across multiple locations, reducing the risk of data loss and downtime.

Simplified Backup and Recovery

Your data won’t suddenly vanish if things go awry. Cloud providers will handle automated backups and provide simple recovery options, so you won’t have to add data backup strategies to your already full plate.

Shorter GTM

By using serverless databases, you can rapidly prototype and deploy apps, shortening the time-to-market for new features and updates. This agility is crucial if you want to outdo your competitors and bring new features to users asap,

With their scalability, cost-effectiveness, managed nature, high availability, and seamless integration, serverless databases make them an excellent choice for building and deploying applications that must be efficient, flexible, and responsive to changing user demands.

Drawbacks of Serverless Databases

Of course, serverless databases are it if you want to reduce the operational burden to maintain the health and capacity of the database properly. However, in our experience, despite a lot of benefits mentioned earlier, serverless databases have their own downsides.

Here are the 4 major drawbacks that can be dealbreakers for your particular case:

Cold Start

Serverless databases can experience delays when responding to the first request after a period of inactivity. It’s commonly referred to as a 'cold start'. This can affect the performance of the app, which makes them impractical for some types of solutions.

Lower Customizability

Typically, serverless databases offer less control and customizability compared to traditional ones. This might not suit apps with specific needs.

Guaranteed Vendor Lock-in

Using serverless databases most often ends up in a vendor lock-in, which makes it super hard to switch providers (but not impossible).

Tough Designing Process

Some databases like DynamoDB have outstanding performance yet require specific knowledge to set up, and the design process can be quite demanding.

Of course, it doesn't mean you have to forget about serverless databases for good. Just pay attention to what's most important to your particular project.

Our Opinion

Managing databases yourself is hard. Using managed and serverless services allows you to focus on delivering value rather than getting bogged down in operational details. This is crucial for small-to-medium businesses and startups. But before you dive head-in, here is a list of things to always keep in mind:

  1. Look closely at the services you’re using: understand their limitations and the cost structure.
  2. Design for failure because things will fail, and that's okay. Create your systems to be resilient to these failures. Always use multi-AZ deployments to protect against the failure of a single availability zone.
  3. Constantly monitor your systems closely and react to feedback quickly. This way, new access patterns and an increased volume of data will affect your billing less likely.


Let’s wrap it up. Serverless databases are the future of modern app development. And it’s already here. By offering fully managed and scalable solutions, cloud providers ease the burden of infrastructure maintenance so that you can pay attention to more important stuff. The benefits of serverless databases include auto-scaling capabilities to handle varying workloads, global accessibility through geographical distribution, and simplified backup and recovery options.

Can I migrate an existing database to a serverless database?

Sure, migrating an existing database to a serverless database is possible. However, it requires careful planning and consideration. Since serverless databases often have different architectures and configurations, you must ensure your data schema and queries are compatible with the new environment. Additionally, take note of any data transfer and migration costs that might be involved in the process. It's a good idea to thoroughly test the migration process in a staging environment to identify and address any potential challenges before making the final move.

Are there any limitations or considerations to consider when using serverless databases?

While serverless databases offer numerous advantages, there are a few limitations and considerations to cover.

Firstly, performance can be affected by the shared nature of serverless environments, so ensure that your apps can handle potential fluctuations in response times. Plus, some serverless databases may have limitations on the size of individual data items or the maximum storage capacity, so make sure your data fits within those constraints. Keep an eye on scaling limits as well, as sudden spikes in traffic might lead to throttling.

Lastly, consider the operational costs, as serverless databases might become more expensive for high-traffic applications than traditional databases.

How can I get started with a serverless database for my modern application?

Getting started with a serverless database is simpler than you might think! First, identify your application's requirements and specific use cases for which you need a serverless database.

Once you've selected the suitable serverless database that suits your needs, sign up for the service with your cloud provider. Next, set up your database instance and configure it according to your application's requirements. And ensure your database is secure with appropriate access controls and authentication mechanisms to protect your data.

Finally, test your application thoroughly in the serverless environment to ensure everything works as expected. And if you need help setting up all of that, get in touch at hello@serverless.direct, and we'll lend you a hand.
