Top 7 Serverless Databases to Use in 2024

Technology keeps evolving with time, and the same is true for databases. First came the traditional databases, where the users had to set up the database server and manage it themselves. Then came managed databases, where the cloud providers manage the servers, but the users can still configure and tune the behavior of the database. Then came serverless databases, where the cloud providers control most of the server management tasks and the database can be auto-scaled. Here, the user can access the database through an interface and focus on their own code without worrying about database management tasks.

However, there are several serverless databases out there from which businesses can choose, and these databases provide multiple features. This makes it harder for businesses to compare each one of them and select the most optimal one based on their requirements. This article discusses what a serverless database is, its various features, and the top 7 serverless databases that users can use in 2024. Let’s get started.

What is a serverless database?

A database using the concept of serverless computing is called a serverless database. What is serverless computing? Basically, “serverless” means that the application is deployed on the server, but the developers who deploy it do not need to manage it. In other words, complex tasks such as database maintenance, scaling, data backup, and security are managed by the service provider.

Moreover, a serverless database can scale automatically based on demand and optimize computing costs as customers pay only for the resources used.

Features of a serverless database

In order to know more about a serverless database, we need to go through some of its features, such as:

1. Fully managed service: From tasks like database maintenance, storage, scaling, security, and data monitoring to performance optimization and service failures, all are handled by the vendor. Therefore, customers can focus on their own work without worrying about the database.
2. Instant access to data: Users can access their data at any time, as a serverless database quickly spins up the resources in no time. Similarly, creating a new database cluster is a matter of a few seconds to a few minutes. Overall, the latency is reduced as data can be easily accessed with functions.
3. High on-demand scalability: In the event of a spike in demand, a serverless database can automatically scale up. If the demand becomes low, computing resources are allocated and the database scales down, which saves resources and thereby reduces costs.
4. Optimized costs: By using a consumption-based model for billing customers, a serverless database reduces costs to a high degree, as the customers only pay for the resources that they use. It is worth mentioning that the users already save a lot as they don’t pay for the servers, data centers, network, etc.

Top 7 Serverless Databases to Use in 2024

There are a bunch of serverless databases that a customer can choose from but here is a list of 7 best serverless databases.

1. Fauna

Fauna is a relational database, and with the help of its document-relational model, it can be used as a NoSQL database combined with some of the functionalities present in relational databases, such as relations, joins, and foreign keys. It is fast, consistent, and reliable.

Features of Fauna

• Easy access to the database: Users can access the Fauna database through drivers in languages such as Go, JavaScript, Python, etc. The same task can be achieved by using the GraphQL API. Moreover, users can interact with the database through Fauna’s own query language called FQL (Fauna query language), which can execute complex business logic. This makes this serverless database very flexible.
• Ease of development: Fauna provides a web shell, which is a web IDE where users can write queries to manipulate data. It also has an extension for Visual Studio Code where users can run FQL queries inside the code editor, and it has been downloaded by more than 5000 users.
• High data security: With attribute-based access control (ABAC), Fauna allows users to establish a strategy for managing identity-based operations. It is an authorization model that protects data and other IT resources from unauthorized users. ABAC extends role-based access control (RBAC), where permissions can be assigned to users based on their roles.

2. PlanetScale

PlanetScale is a MySQL database that supports globally distributed apps with read-only regions. This database does not compromise on scalability, reliability, or performance. Therefore, it brings solid developer experience. It also allows horizontal sharding and schema changes that are non-blocking.

Features of PlanetScale

• Version control of the database: Just like how code can be kept in different branches, PlanetScale provides the feature of branching a user’s database. This enables high productivity, as developers can work on different versions of the database simultaneously. Moreover, developers can merge databases without any downtime.
• Reduced load on a database: PlanetScale offers horizontal scaling via sharding that reduces the overall load on a database. This process is hard to manage, so PlanetScale has kept most of the logic of sharding out of the application.
• CLI and API for interaction: pscale CLI offers developers the ability to perform almost any operation that is possible on the dashboard of PlanetScale. That includes commands for backups, branding, and requests for deployment. Developers can also interact with PlanetScale using the API for faster development workflows.

3. MongoDB Atlas

MongoDB Atlas is a NoSQL database on the cloud that can be hosted on AWS, Google Cloud, and Microsoft Azure and is available in over 90 regions around the world.
