Microservice eCommerce architecture is key to rapidly building and optimize the eCommerce experience

Several crucial features and components enhance a user’s overall experience. The parts need to be regularly updated and modified to meet changing user needs or rebranding criteria. Allows for rapid deployment and scalability by using Microservices architecture for ecommerce. Constructing independent modules that aren’t intertwined is a common strategy for B2-B companies like Concord Commerce. 

APIs connect individual microservices, then assembled into a single platform using Microservices architecture for ecommerce. The same microservices on the back end can be used to build many user interfaces. There are various advantages for organizations in using this architectural style, even though developers are more interested in learning about its quirks.

  • A monolithic Ecommerce platform’s rigid technology stack does not limit the development of new features. Ecommerce applications that are both beautiful and speedy can be created using this method.
  • Small development teams can work on multiple services for rapid application deployment and market entrance.
  • Ecommerce architecture migration is an investment that should be done in stages. You may upgrade and rebuild the modular eCommerce solution using an ecommerce microservices architecture step by step. Custom workflow and design can significantly impact the Ecommerce customer experience.
  • Scaling an Ecommerce platform built on microservices is simpler and less expensive because each service has its life cycle, which includes creation, modification, testing, and removal (if necessary). It’s a win-win situation for companies looking to expand their online presence over the long term.
  • ecommerce microservices architecture (and thus online sales) are more stable because a single microservice fault doesn’t affect the entire application. This makes online sales more resilient.
  • Each service can be hosted on a distinct cloud instance based on its bandwidth needs, which reduces infrastructure costs.

What is ecommerce microservices architecture, and Why does it matter?

The cloud-native design provides self-contained discrete business functionality that may be invoked over a network utilizing widely available protocols if you’re not familiar with the technology. Functionality components are segregated from the user interface and may be utilized across channels (UI). Headless commerce is a Microservices eCommerce architecture term for separating the ecommerce functionality from the user interface. The foundation of a scalable and flexible Ecommerce platform is a Microservices architecture for ecommerce.

Ecommerce platforms should ideally have a flexible microservices design, yet many businesses now have a monolithic ecommerce website. An all-out re-platform can be time-consuming, expensive, and unsafe for your organization. To ease the transition, you can consume microservices more gradually. Legacy services can be replaced with cloud-native microservices by adopting a strategic plan and retiring them over time. Integrating existing on-premise and third-party systems via an integration layer that supports APIs, flat files, batch feeds, and event alerts is possible. Overall, this method is more manageable and less harmful to your company.

Challenges posed by Microservice 

A cross-functional structure with vertical teams that operate independently is required for microservices instead of the traditional horizontal organization. The correct infrastructure and tools will be necessary for organisations to orchestrate and monitor their Microservices eCommerce Architecture. ” Choosing microservices presents the following difficulties:

Decentralized information

One set of data exists for each microservice. Managing several databases and transactions necessitates a higher level of care.


All dependent services must be tested during the testing of a microservices-based application. This makes end-to-end and integration testing more challenging, but it also makes them more vital because even a few hops away, one failure can trigger something else.


Deployment, especially in the beginning, takes careful attention. You’ll need to think about the order in which services are implemented. It will be required to invest in deployment automation.


To find bugs, you need a unified picture of the entire system. It’s not possible to use remote bugging on several services.

Additionally, new difficulties may occur because of the increased reliance on messaging by microservices. It can be difficult to communicate effectively if you don’t use automation and cutting-edge approaches like Agile. Network administrators will need DevOps tools like CI/CD servers, configuration management platforms, and APM tools to deal with this. To ensure that the services are deployed successfully and monitor if they function together as planned, you need a common container orchestration system, several tiers of load balancing, and service discovery. Ecommerce microservices architecture is a breeze to get started with for companies already employing these solutions. This can be a problem for smaller firms if these additional standards must be implemented.

Now, let’s take a look at some of the most important aspects of a modern Ecommerce platform.

As we’ve covered in this introduction to cloud ecommerce microservices architecture, it’s time to move on to the next step, deciding on an Ecommerce platform. The cloud-native microservices-based headless Ecommerce platform is an example of a future-proof design for merchants that can accommodate new and changing technologies while providing agility, flexibility, dependability, and scalability. When making your final decision on an Ecommerce platform, keep the following aspects in mind:

  • A wide range of pre-installed features
  • Quick deployment of new features and capabilities thanks to the ability to change course swiftly
  • Customer relationship management (CRM), enterprise resource planning (ERP), supply chain, inventory, payment systems, and the like can be seamlessly integrated to give a unified shopping experience.
  • The capacity to grow and contract on demand when client demand fluctuates.


Microservices Architecture features that make it ideal for eCommerce


It allows for the addition of new features to meet the demands of various types of businesses. Competitive advantage is gained by providing unique services that meet consumers’ needs.


The architecture is designed to be extendable to scale the front and back end independently. Customers will be satisfied with the high level of service they receive. Scalability can be added to certain services without changing the entire platform.


Thanks to speedier deployment, change and alignment with business can bring a Modular eCommerce Solution more quickly. Its decentralized development method makes it simple to change the code and offers a fresh Ecommerce customer experience.

Efficiency in terms of price

It is possible to add functionality and only pay for the microservice you use with the microservice strategy. As a result, the technology stack can be made smaller and more efficient.

Benefits to ecommerce using microservices

With microservices, organizations can adapt and expand their Ecommerce platforms far more quickly and easily than with monolithic systems. Innovative features, technology, and capacities are welcome in the workplace. Microservices eCommerce architecture has several advantages, including:


When troubleshooting issues, microservices can be isolated from the broader platform ecosystem because they run independently of one other. As a result, the overall system will be less affected by the failure of a single microservice. The platform’s stability is not jeopardized because each microservice may be built, tested, and launched individually.

To get to market in a short period.

You may swiftly experiment with new technologies, systems, and approaches to solving problems with decentralization. Because it doesn’t restrict developers to a single platform or programming language, it also allows them to work on their preferred platforms and languages. There is no need to rebuild the complete system (or take it offline for long periods) to test and apply the latest Ecommerce technology.

Scalability is better

The modularity and scalability of microservices are one of their greatest advantages. What you have is all that you need. For cutting-edge features that will make your company stand out from the competition, a modular “rollout” strategy means that new functionality can be introduced much more quickly, allowing you to have a faster time to market.

Downtime is reduced

Decoupling services reduces the time it takes to develop new features while also reducing the likelihood of the entire system failing if one of the services fails. The overall system can continue working while the faulty service is being fixed, resulting in a superior level of resilience for the overall system.

Streamlined codebase

Because microservices are separated from the rest of the system, they are easier to manage and upgrade. Major changes necessitate updating the entire codebase in a monolithic system. This isn’t the case with microservices, as they are separate systems within a system. Using microservices for e-commerce allows you a wide range of customization options.

Concerning disadvantages, what should be noted?

Organizations must consider both the benefits and drawbacks of using multiservice architecture before making a final decision. Complexity is one of the drawbacks.

Managing applications with a lot of moving elements can be a challenge. Because individual processes are easier to comprehend under a microservice design, there are a lot of processes. Each of these things needs time and attention. To construct a successful microservice-based platform, our highly competent tech teams recognize the importance of the interdependencies between the services.


Planning and communication must be crystal clear for an ecommerce microservices architecture to succeed. Architects and developers must carefully analyze the microservices required and construct them in a way that plans interdependencies and maximizes functionality as well as possible.


The benefits of microservice architecture are reduced if a project is too tiny. When the system grows too large, it becomes too difficult to maintain. To successfully design and maintain a product, it is critical to establish a balance between the features and capabilities of the development team.

Services Provided by Third Parties

Microservices are frequently outsourced to third-party vendors. The application has elements that the business does not have access to. Third-party developers can change their policies, causing the application to break down.

Microservices vs. Monolithic Software

Smaller firms may profit from a monolithic application despite its common use. There are fewer investment and proficiency requirements for the simple application development procedure. This makes it simpler for new businesses, particularly startups, to create and maintain.

Simple, static apps can be built with monolithic applications, which require nothing in the way of refactoring in the future. The monolithic structure is ideal for quickly validating business ideas and launching an app with minimal input needs.

Using a microservice architecture necessitates more capital. It’s imperative to hire a DevOps and container expert. A clear separation of duties is achieved by addressing the different functionalities of each one. The building becomes more difficult, but it is more complete when small teams are formed to tackle specific jobs.

When it comes to firms who plan on rebranding or developing new products in the future, microservice architecture is an excellent investment. If firms look at each microservice independently, they may determine which parts need updating and which parts can keep running. Microservice architecture is better suited to large-scale application development.

What framework is suitable for your firm depends on the available resources and the complexity of the application you’re developing.

In 2022, why is microservices-based e-commerce so crucial?

To stay up with the rapid speed of industry change and customer demands, retailers embrace microservices as part of a headless commerce strategy.

Decoupling the front-end (e.g., your online storefront) from the back-end of a headless Ecommerce platform is called “headless commerce” (your data and transactions layer).

As a result of their capacity to be customized and scaled infinitely, decoupled microservices offer headless operations. As your business grows, you can use only the goods, services, and capabilities you require.

Your customers can have a seamless buying experience across online and offline channels when using a microservices-based ecommerce strategy.

In light of the growing trend of hybrid buying techniques, such as buying online, picking up in-store, and clicking and collecting, this is critical (up 125 percent and 52 percent last year, per AdAge.)

In light of store closures and lingering pandemic concerns, consumers keep a close eye on their spending habits. Good shopping experiences are being rewarded by the retailers who can provide them. Customers are willing to pay up to 16% extra for goods and services when they are treated well, according to PwC.

Microservices allow merchants to meet customers’ expectations for seamless omnichannel experiences because of their flexibility and scalability. Using microservices, you can “future proof” your Ecommerce platform by adding new features and functionalities as they become necessary.

Connected retail experiences may be easily delivered using applications that increase functionality and personalize the buying experience with recommendations, reviews, and tailored offers.

Reasons for migrating to headless commerce  and microservices Architecture 

It’s no surprise that business brands are now looking for alternatives to monolithic systems. An ecommerce microservices architecture provides a flexible base for fast responding to consumer requests and market developments.

Using loosely connected microservice components to build a complete system is advantageous for developers and end-users.

Back-end performance is unaffected by high levels of front-end activity.

The front-end and back-end can be scaled independently of one other in a microservice architecture. Developers can add new features to the system without affecting the rest. Back-end activities will not be adversely affected by heavy traffic on the front-end.

Customization and individualization are now easier to achieve.

User interfaces can access one back end as long as they are all connected to the same headless system. The front-end can benefit from a slew of new touchpoints as a result.

It is possible to implement quickly.

A decentralized development process using microservices or headless systems makes it easier for developers from different teams to cooperate to alter the code base and go to market more quickly.

Only purchase what you require.

A monolith is a feature-rich, all-in-one system. Still, you may be forced to pay for and work around features and capabilities that your company does not want in the long run.. Each microservice in a microservices architecture is responsible for a specific business task or task set. You can only add what you need to your system, resulting in a more efficient and lighter technology stack.

Get the finest of the best.

Pick and choose the services and service providers that specialize in exactly what you need rather than depending on one system to do everything. This technique will help you zero in on the services that best suit your company’s unique requirements. On the other hand, Concord commerce offers greater flexibility at a lower cost.

Let’s dwell on how Headless Architecture is Different from Microservices Architecture?

Some aspects of the system are disconnected in headless mode (the front-end from the back-end). On the other hand, true microservices architecture decouples the platform and service-oriented architecture.

Both decoupled and headless platforms separate the content management and content delivery contexts. Rather, the content is actively pushed into the delivery environment in a decoupled system. In contrast, a headless CMS is passive and waits for a content request.

Third-party applications that publish content using a headless CMS can access its API for content generation and editorial purposes. With all the headless and decoupled CMS characteristics, the decoupled CMS is more proactive. Preparation and delivery are both covered by this service.



There are numerous aspects to take into account when developing an Ecommerce platform. An efficient back end and a flexible front end are essential for a successful online business model. We can keep the application’s development and operation simple by breaking this procedure into parts. These “trends” in digital commerce, from Omnichannel Commerce to headless architecture and other modular approaches via microservices architecture, reflect something larger: the growing demand for many companies to create seamless, multi-channel experiences that provide personalized convenience for each customer.

The Concord Commerce application uses an ecommerce microservices architecture first strategy to ensure that feature development is flexible and future-proof. The segmentation makes tracking and rebuilding components as needed an easy operation. Agility could be the key to keeping your rivals from overtaking you in speed and effectiveness in eCommerce. Our consumers will enjoy additional benefits from our SaaS platform if we migrate to a microservices architecture.
