Microservices Architecture Implementation on eCommerce

Manju Naglapur | 4 min read

Ecommerce companies often struggle to woo their online consumers due to the friction of decade-old traditional slow-moving platforms that are monolithic architecture. These architectures have components that are interconnected and interdependent, opposite to a microservices architecture, that acts as standalone applications, as well as are sophisticated versions of a modular architecture.

Microservices have numerous individual services that can be swapped out with ease to keep an e-commerce business current, more agile, and able to deploy faster.

An e-commerce company that has a microservices-based architecture can build and deploy whatever it wants, whenever it wants and as much as it wants, unconstrained by fixed deployments. The microservices-based e-commerce platform brings flexibility to the enterprise by making it easier to implement new features and capabilities, even during massive growth phases.

What is an e-commerce Microservices Architecture?

This kind of architecture contains separate services that have individual code bases. The communication of these separate services is accomplished using serverless events and is connected to frontend shopping experiences with APIs. Overall this architecture gives the ability to design a world-class e-commerce platform by selecting the best possible services.

Why are brands adopting Microservices for e-commerce?

Microservices for e-commerce can deliver code within a service independently, without impacting other pieces, and without restarting the entire platform. Adding and testing new site features becomes easy and it also allows developers and brand marketers to think more creatively.

Use Cases of Microservices in eCommerce

Leading eCommerce giants eBay, Etsy, Gilt, and Zalando transformed their infrastructures into microservice to create flexible, global systems and a whole new working culture, which is easy-to-enter and motivating for developers.

eBay: Back in 2011, eBay dealt with massive traffic as they had about 97 million active users and 62 billion gross merchandise volume. eBay implemented microservice architecture to answer the arising challenges of the growing complexity of the codebase and improving developers’ productivity while maintaining site stability.

Gilt: Gilt adopted the microservice architecture in 2011 and recreated 156 services, rebuilt their system, and also rearranged their teams. This shift resulted in fewer dependencies between teams, running initiatives in parallel, supporting multiple technologies, and promoting ease of innovation.

Etsy: Etsy developers redesigned their microservice architecture and made it compatible with the change, continuous experimentation, and frequent deployments.

Characteristics of Microservices Architecture that are great for eCommerce

Flexibility: It provides flexibility in adding new functionality that allows the use of specific services tailored to specific business needs. The unique services give a competitive advantage and help add value to the customer needs.

Scalability: The architecture is designed to extendability to scale the front end and back end individually. This results in the high performance required for a perfect customer experience. Scalability for specific services can be extended as needed without having to modify the entire platform.

Agility: Facilitates faster implementation that brings rapid change and alignment with the business digital commerce strategy. Its decentralized development process enables easy code adjustments and brings a new customer experience.

Cost efficiency: In the microservice approach, you add functionality and pay only for the microservice you use. This helps create a more compact and efficient technology stack.

Benefits of Microservices for eCommerce

1.Microservices prepare eCommerce platforms for traffic peaks, implement and test out the latest trends, like new payment methods and voice assistants, without significant risks.

2.It assists in setting up omni-channels to enable syncing and uniformity of every piece of information about products, shipments, stocks, and orders and keep it all up to date – across all channels.

3.It enables the use of API gateways to integrate POS, ERP, or WMS solutions that are best-in-category, and synchronize them with existing processes.

4.Reduces the complexity of software and makes their maintenance and updating easier.

5.Helps choose the right tool for the right task and enables the use of best-suited language, framework, or ancillary services.

6.Builds a cross-functional connection which reduces synchronization efforts between teams and allows significantly faster deployment.

7.Creates interdependence for cases when one service no longer responds, the rest of the application still functions and doesn’t break the whole application. It has no single point of failure and maintenance and failure, if any, do not affect the customers.

8.These allow the ease of scaling up and increase the overall performance of the whole business application.

Should you consider microservices for your eCommerce platform?

Microservices no doubt improves the performance of eCommerce platforms but you need to pay attention to vast containerized hosting clusters, deploying new code needs advanced orchestration, and make sure you don’t get lost in the sea of small codes!


eCommerce businesses should rejoice as incorporating microservices doesn’t require a full re-platforming effort right away. Well-crafted API’s connect you to your services and allow you to tackle the most critical parts of your platform. If you want to extend independently to new touchpoints, such as in-store digital experiences, mobile apps, and shoppable content then consider components that have an immediate need to scale.
