11 Serverless Databases for Modern Scalable Applications: A Comprehensive Guide

Introduction to Serverless Database

Serverless databases are a type of cloud-based database that can automatically scale and provision additional resources as needed when in demand. There will not be any overhead of managing the underlying infrastructure, such as servers, storage, and backups. These databases offer a variety of features, such as support for different data models (SQL, NoSQL, document, etc.), ACID transactions, and geo-replication.

Serverless databases have become a chosen option for the applications that have unpredictable workloads or that need to scale quickly. Serverless databases are becoming more popular in the recent years after the adoption of Serverless technologies among the organizations.

The main features of serverless databases are:

  • Automatic scaling: Serverless databases automatically scale up or down based on demand, so you never have to worry about provisioning or managing capacity.
  • On-demand billing: You only pay for the resources that you use, so serverless databases can be very cost-effective.
  • Simplicity: Serverless databases are easy to use and manage, so you can focus on developing your applications instead of managing your database infrastructure.
  • Reliability: Serverless databases are highly reliable and available, with built-in redundancy and disaster recovery.

In addition to these core features, serverless databases often offer other features such as:

  • Real-time data synchronization: This feature allows you to keep your data synchronized across multiple devices in real time, making it ideal for building mobile and web applications.
  • Geographically distributed databases: This feature allows you to store your data in multiple regions around the world, improving performance and reliability for global users.
  • Managed backups and restore: Serverless databases typically offer managed backups and restore, so you don’t have to worry about backing up your data or restoring it in the event of a failure.
  • Security features: Serverless databases offer robust security features, such as encryption, access control, and auditing.

Serverless Databases are the best choice for applications as given below:

  • Web applications
  • Mobile applications
  • IoT applications
  • Big data applications
  • Real-time data applications
  • Mission-critical applications
  • Enterprise applications

Below given are some the mostly used Serverless databases by the organizations.

1.Amazon Aurora Serverless

Amazon Aurora is a powerful relational database offered by Amazon that supports both PostgreSQL and MySQL compatibility. It combines the accessibility and performance of traditional databases with the reliability and simplicity of commercial databases, all at a fraction of the cost—only 1/10th of traditional database solutions.

One of the key features of Amazon Aurora is its innovative clustered approach to data replication, leveraging AWS’ availability zones for efficient and robust data availability. This ensures that your data is highly accessible and reliable, with built-in redundancy and fault tolerance.

Amazon Aurora incorporates high-performance subsystems, utilizing the fastest distributed storage for both MySQL and PostgreSQL engines. This results in impressive throughput improvements, with a 5x boost for MySQL and a 3x enhancement for PostgreSQL, compared to existing systems. This performance optimization contributes to a more responsive and efficient database experience for users.

In terms of scalability, Amazon Aurora provides substantial support for enterprise-level implementations by allowing databases to scale up to an impressive 64 terabytes. This scalability ensures that the database can grow with the evolving needs of your organization, accommodating large datasets and demanding workloads.

An additional advantage of Amazon Aurora is its seamless integration with Amazon Relational Database Service (RDS), providing a fully managed environment. This means that administrative tasks, including hardware provisioning, data organization, maintenance, backups, and more, are automated by Amazon RDS. This automation not only simplifies database management but also enhances overall system reliability.

In summary, Amazon Aurora stands out as a cost-effective, highly performant, and scalable relational database solution, fully managed by Amazon RDS, making it a compelling choice for enterprises seeking a robust and efficient database infrastructure.

2.Azure SQL Serverless

Azure SQL Serverless is a serverless compute tier for Azure SQL Database that automatically scales compute based on workload demand and bills for the amount of compute used per second. It is a good option for applications with unpredictable workloads or that need to scale quickly.

Azure SQL Serverless offers a number of features, including:

  • Automatic scaling: Azure SQL Serverless automatically scales up and down based on your workload demands. This means that you don’t have to worry about provisioning or managing additional servers.
  • Pay-as-you-go pricing: Azure SQL Serverless uses a pay-as-you-go pricing model, so you only pay for the resources that you use. This can be a significant cost saving for applications with unpredictable workloads.
  • Reduced operational overhead: Azure SQL Serverless eliminates the need to manage the underlying infrastructure, such as servers, storage, and backups. This can save you a lot of time and money.
  • High availability: Azure SQL Serverless is highly available, meaning that your data is always accessible.
  • Security: Azure SQL Serverless is designed with security in mind. It offers features such as encryption, authentication, and authorization.

Azure SQL Serverless is a good option for a variety of applications, including:

  • Web applications with unpredictable workloads
  • Mobile applications
  • IoT applications
  • Data warehousing applications
  • Machine learning applications

To get started with Azure SQL Serverless, you can create a new Azure SQL Database instance and select the serverless compute tier. You can also migrate an existing Azure SQL Database instance to the serverless compute tier.
