The global serverless architecture market, valued at over USD 9 billion in 2022, is projected to burgeon at a CAGR of over 25% from 2023 to 2032​. Similarly, the global serverless computing market is estimated to grow at a CAGR of 20.8% from 2022 to 2028​.

The statistics we mentioned above testify to the significant strides the serverless approach is making. It's (kind of) evident that if you haven't done so already, now is the time to delve deeper and enumerate serverless benefits, check real-world use cases, discuss technical considerations, and understand best practices for businesses eyeing a transition to this modern eCommerce paradigm.

But before all that we've got some term explaining first.

Serverless Explained

The term serverless might evoke a notion of a system operating without servers, which is a misnomer. Serverless refers to an architecture model where developers can build and run applications and services without managing server infrastructure.

The cloud service provider (such as AWS, Google Cloud, Azure, Vercel, Cloudflare, etc.) automatically manages the provisioning of servers and, in most cases, just executes your server-side code, letting developers focus more on building the applications.

What About Serverless eCommerce?

Serverless eCommerce is an evolution in eCommerce development that leverages serverless computing. Unlike traditional setups requiring dedicated servers and hefty management, serverless eCommerce abstracts away much of the server management and operational responsibilities. This abstraction allows for automatic scaling, reduced operational overhead, and a pay-as-you-go pricing model.

A Simple Example of Serverless Architecture

A classic serverless eCommerce architecture setup can hold the following components (and more):

  1. The User Interface (UI) is where customers interact with the eCommerce platform. It typically includes a web application but could also have mobile applications. A UI most likely does not need a server, and a browser can execute the code as it is served by the Content Delivery Network (CDN). There is no computation to be executed here. This may include HTML, CSS, and JavaScript.
  2. Content Delivery Network (CDN) will also deliver users the static content of the eCommerce platform, such as images, videos, fonts, sounds, etc.
  3. An Optional API Gateway handles routing requests from the UI to the appropriate serverless functions or services. It acts as a front door to manage and analyze REST, HTTP, and WebSocket traffic to back-end services.
  4. Serverless Functions (e.g., AWS Lambda, Azure Functions) execute code in response to events triggered by the UI or other services. They handle business logic, read from or write to databases, and interact with other services. They are the ones computing; they execute the code and die.
  5. A database, often a managed service, stores data related to the eCommerce platform, including product catalogs, customer data, and order history. Many serverless databases exist (Aurora, DynamoDB, MongoDB Atlas, PlanetScale, Neon, etc.), and they are bringing serverless abstraction to the data: the computation unit to mutate or query data in the DB is serverless as well.
  6. Event sources trigger serverless functions. These can include changes to data in a database, new files in a storage bucket, or custom events. Your browser hitting the home page is also a trigger!
  7. Identity and Access Management (IAM) controls who can access various resources and services within the architecture, including both human users and automated processes. There is most likely a JWT Token here, but not only.
  8. Third-party services and APIs include payment processing systems, shipping services, and other external services with which the eCommerce platform interacts.
  9. Monitoring and logging services collect metrics, logs, and trace data to ensure the system operates correctly and provides insights into its performance and usage.

Finally, storage services hold static and dynamic files, images, and other necessary assets for the eCommerce platform.

A Simple Example of Serverless Architecture vs. Traditional

Benefits of Serverless eCommerce

The migration towards an eCommerce platform that relies on serverless architecture is driven by myriad benefits that address the conventional challenges of managing online retail platforms. Here are some of the key advantages.


Serverless architectures are designed to scale resources automatically based on incoming traffic and workload. This auto-scaling feature ensures the system can handle traffic surges during peak times, such as sales events, without requiring manual intervention to provision or de-provision resources. This is particularly beneficial for eCommerce platforms where traffic can be highly variable.

Cost Efficiency

Serverless eCommerce operates on a pay-as-you-go pricing model, where businesses are billed based on the actual usage of resources rather than having to pay for pre-allocated server capacities. This model significantly reduces operational costs, making it a cost-effective solution for small to medium-sized enterprises. It’s very similar to automatically bootstrapping a machine but way more efficient and cheap. For instance, Cloudflare worker charges on CPU time; if the CPU is idle waiting for another resource, you don’t pay!

Operational Simplification

With server management abstracted away, businesses can focus more on core functionalities and innovate on the customer experience. The reduced operational burden accelerates the development cycle, enabling faster deployment of new features and improvements. No more never-ending Terraform configuration, or at least a much simpler one!

Real-Time Event Processing

Serverless eCommerce platforms can process events in real time, enabling dynamic and interactive user experiences. This real-time processing capability is essential for features like inventory updates, price adjustments, and personalized recommendations, which are crucial for maintaining an up-to-date and engaging eCommerce platform.

Enhanced Performance

The on-demand allocation of resources in serverless architectures ensures that the system operates at optimal performance levels. Resources are made available precisely when needed, minimizing latency and enhancing the user experience, which is critical in the competitive eCommerce space. Moreover, code execution can happen on the Edge. The code is executed close to your users, and the latency is reduced drastically, which is crucial in eCommerce.
