Serverless Databases in the Era of Edge Computing

In the computing-edge realm, serverless computing has become widely popular. This specific paradigm shift provides a bunch of advantages and benefits, thereby reshaping the way in which apps are deployed and developed. Edge computing has become the need of the hour as it provides a bunch of benefits, such as decreased operational complexity and streamlined scalability.

What is edge computing?

Edge computing happens to be the approach to the different backend services, which function on a usage-driven model. As you opt for the serverless service provider, the potential users develop and deploy the code without involving the complications of managing and handling the underlying infrastructure.

As the developers opt for the setup, they can opt for the backend services, along with the pay as you go approach. It indicates that they will be charged for the used resources only. Hence, the developers will be able to focus on the work without worrying about server-related concerns.

Features of edge computing

The features of edge computing include:

Automatic scaling

The cloud service provider allows you to handle the scaling of different resources, which are essential to running the application code in response to different incoming events. It reduces the need for the developers to handle the scaling manually, depending on different traffic fluctuations.

Event-driven execution

The different serverless apps get triggered by different events, such as database changes, HTTP requests, timers, and file uploads. Once the event occurs, the cloud service providers scale up different resources automatically, which help handle the event and run the associated code.

Decreased administrative overhead

The developers do not need to worry about networking configurations, OS updates, managing the servers, or different infrastructure-related tasks. Thus, they can concentrate on code writing and delivering the latest features.

Why go for edge computing?

Edge computing allows you to create services and applications without thinking about the underlying servers. At its core, it is regarded as an architectural movement that helps boost agility through a reduced TCO, or total cost of ownership.

CDNs, medical devices, IoT devices, and smart CCTV cameras are recognized as use cases of edge computing. Edge computing is not without its risks. It is difficult to go a single day without worrying about the different security problems of smart devices, with the faster adoption of the Internet of Things across different sectors. Edge computing scalability helps mitigate different security threats.

These are some of the major challenges that serverless databases face:

  • The developers do not need to control the hardware. Hence, abstraction happens to be the key.
  • The edge world happens to be an untrusted environment. Hence, you need rigid sandboxing.
  • Edge computing developers process unpredictability in real-time data at scale. Hence, you need the scalable elastic model for computing.
  • The typical computers that are used at different edge locations should be affordable and small. Hence, they function in a low-resource environment when it comes to RAM, CPU, and disk. So, it is important to have smaller memory and storage footprints and compute efficiency.

Serverless has been maturing since its inception. The tooling improves massively in the open-source and vendor-side spaces. Thus, the practitioner develops the mental models and best practices to work in a serverless environment. Such advances allow the rise of edge computing.

The developers use the coding in the stateless and abstract runtime environment, integrating with third parties and serverless databases with an elegant design pattern. Such a paradigm shift occurs from the Serverless Application compute model to the edge compute model and is marginal.

Serverless happens to be the enabler for the edge. In the distributed, event-driven, pay-per-use and stateless mindset, the serverless paradigm is triggered. Such a paradigm shift happens to be the key that allows the adoption of edge computing.

Benefits of serverless databases in edge computing

Here are some of the primary benefits of serverless databases in edge computing:

Reduced operational costs

Serverless databases play an integral role in significantly decreasing operational costs. Hence, you need to pay any amount for the servers, data centers, cooling, power, networks, and human resources.

Thus, the cloud service providers will be capable of accommodating several tenants that share similar services and infrastructure, leading to lower costs for every individual tenant. Henceforth, the serverless backend databases will pay for the specific usage, like the requests executed and the consumed space.

Simpler operations and higher productivity

If there is no capacity planning, infrastructure management, or manual scaling, operations can be simplified. Thus, the developers will spend the time they have saved on business logic, application design, and coding. The result happens to be a faster time to market and higher productivity.

Auto-scaling and elasticity

Automatic scaling, along with going up and down with demand, is regarded as an integral feature of serverless databases. It decreases the costs with the scaling as the demand becomes low. Moreover, it boosts availability and throughput with the scaling up as demand increases. Auto-scaling and elasticity happen to be the core parts of the serverless database design.

Effortless scalability

Serverless architecture plays an integral role in streamlining scalability. Thus, the developers do not need to handle the scaling priorities. Hence, the serverless service provider can take the prerequisite care of different dynamically scaling resources, catering to the needs.

Boosting the development

The server architecture boosts the time to market. In place of complicated deployment processes for the updates, the developers will be able to implement the changes incrementally, rolling out different bug fixes faster.

Simplifying backend coding

Through function as a service, the developers create different straightforward functions that can execute single tasks independently. Such a modular approach decreases the complications of coding.


Serverless databases have become the need of the hour owing to their budget-friendliness. Here, the users are charged according to their actual usage. Thus, the serverless mobile backend helps reduce the wastage of space and idle processing power.

Though serverless databases come with their own challenges, the benefits they offer make them a better choice than other approaches. Thus, it helps to save an ample amount of money.
