Which AWS service is the best option to use if you need a NoSQL database that is serverless?

Serverless is the future! It is the next-generation approach that lowers the efforts needed to manage and streamline development operations while delivering massive value for business applications. Serverless databases scale automatically based on requests and do not require a lot of capacity planning. In today’s digital age, enterprises need to integrate data reliably into applications that require a secure and highly scalable data infrastructure. This is what serverless databases are trying to solve.

The serverless approach has been adopted worldwide due to its high transparency, faster performance, cost-effectiveness, instant availability, and operating infrastructure support at a large scale. In today’s post, we will talk about the modern database solutions that will help you to streamline database deployment and management. 

Earlier developers needed specific hardware to process the database when they had to build and deploy applications. It was a time-consuming process because a developer had to wait to receive the server first, followed by the prolonged process of unboxing, installing, cabling, configuring, and deploying applications manually. Traditional database systems launched 20+ years ago require complex sharding and heavy operational management, which ultimately increases costs to develop critical applications. 

However, today, the scenario has changed, thanks to the serverless infrastructure. Now, developers do not need to go through this lengthy process to maintain the database; they can do the same in just a few minutes securely in a public cloud. 

Embracing the New Serverless Paradigm: Serverless Database

A Serverless database enables developers to build applications utilizing infrastructure without a specialized hardware platform. It is designed to manage the unpredictable and rapidly changing workloads of developers. A service provider runs the server and automatically allocates the required resources to developers. 

The serverless database platform is scalable and charged based on the requirements, i.e., it is based on the pay-as-you-use model to maintain the database by third-party service providers. They continuously work to meet the fluctuating demand of developers by providing the database-as-a-service. 

The ultimate goal of the serverless database is to simplify the management of the database by providing automated scaling and low ops requirements. 

With the serverless database, you can avoid issues associated with traditional environments such as cost, security, time, troubleshooting, and maintenance. A Serverless database can be used to develop applications in industries like retail, eCommerce, telecommunications, and finance.

Key Elements of a Serverless Database

Let’s have a look at key elements of a Serverless Database:

• Automated Elastic Scale

  The scalable serverless database meets the unexpected demands of developers worldwide, i.e., it scales down to zero when there’s no demand, and it spins up automatically when any requirement comes in from any region. Some of them are capable of moving data all around the world, enabling users a frictionless experience. 

• Simplicity 

  The serverless database is simple and easy to use for developers and beginners as well. For them, it is as simple as working with an API. Simplistic features like self-service start and REST APIs with fully manageable operations make the serverless database the first choice for developers to manage and control the app database.

• Speed of Deployment

  The serverless database management system is faster as compared to the traditional system and easy to use. You can create a new cluster of databases in a few minutes. You do not need to spend your time installing, capacity planning, scaling, and configuring your database like a traditional system.

• Consumption-based Billing

  As discussed above, the serverless database is the cost-effective model as it is charged based on consumption, i.e., it follows the pay-as-you-use model. You do not need to pay for storage; you have to pay for the resources you use. You can also set a spending limit in case you look forward to avoiding budget overrun. 

Why You Should Use A Serverless Database

Ideally, the serverless database is a great fit for small companies or companies with limited staff members. It requires very little maintenance and infrastructure support with fewer man-hours. Besides, it has other advantages as mentioned below:

• Cost-effective and High Scalability

  With the serverless database, you can save your time and avoid operational overhead costs that include license, installation, cabling, configuration, maintenance, and support. Operators or developers do not need to set up scaling computing systems manually. In addition, you can optimally utilize resources based on your requirements to build applications. You do not need to pay more for underutilized resources, just pay for what you use and focus on what matters the most to build high-quality applications. 

• Improved Operations, Scalability, and Performance

  Rely on, always available, and easy to handle serverless databases to improve your digital product development operations. Instead of hassling efforts related to database management, your developers can use time, memory, or resources efficiently to build, deploy, and maintain applications. Because the database-as-a-service provider is responsible for scaling the capacity to meet your new product development needs. Furthermore, developers or development teams do not need to depend on a separate infrastructure support team. They can focus on coding and run the code independently and deliver applications faster. Adopting the serverless paradigm has enabled developers to shorten the product development life cycle by weeks, offering faster market launches for their products. 

• Highly Secure

  Keeping your database secure is important when it comes to rapid application development in today’s digital world. Because applications are more exposed to cyber risks nowadays. And database-as-a-service providers are responsible for securing all the cloud components and OS vulnerabilities. However, serverless brings new security challenges for developers as they are responsible for developing applications by writing application logic, code, data, and security-related layered configurations. When using the serverless database, the platform handles resources, monitors all the running servers, manages OS patches, eliminates any compromised server automatically, and copes with its negative equivalent. 

Let’s Explore Top 6 Serverless Databases To Use For Your New Project in 2022

Various types of databases are available for developers, such as centralized databases, distributed databases, relational databases, object-oriented databases, non-relational databases, semi-structured and unstructured databases, time-series databases,  hierarchical databases, etc. To develop a great application, you, as an enterprise, should choose a suitable database management system as the type of database affects your development life cycle and market launch. So, let’s get started with one of the most popular and highly effective serverless databases you can use in 2022 which can accelerate your product development life cycle. 

[A] Relational Serverless Databases

2. PlanetScale DB Serverless
3. Amazon Aurora Serverless

[B] NoSQL Serverless Databases

1. Amazon DynamoDB
2. Google FireStore
3. Fauna DB

Let’s understand these serverless databases in detail.

[A] Relational Serverless Database

A relational database is a type of database that collects and organizes data based on predefined relationships of key data points. It structures data in such a way that makes it easy for multiple users to find and sort without affecting the logical data categorization. It eliminates the data deduplication in storage procedures. The application program interface (API) of a relational database is Structured Query Language (SQL). 

In this system, data is presented in a tabular form. And this table represents an entity e.g., a product/mobile app. Whereas each row represents the actual value with a unique identifier which is an instance of that type of entity,  that’s why it’s called records. On the other hand, the columns hold the attributes of that data, i.e., the actual value attributed to that entity; that’s why they are called attributes. You can access the data without reorganizing the database table. 

Examples:

• Standard relational databases include MySQL, Microsoft SQL Server, Oracle Database, and IBM DB2
• Cloud relational databases include Google Cloud SQL, Amazon Relational Database Service, IBM DB2 on Cloud, SQL Azure, and Oracle Cloud
