How to build a scalable eCommerce
architecture with microservice

In recent years, microservices have been marketed as the following approach to designing flexible, easily scalable, and fast-to-deploy infrastructures. As online sales continue to evolve, they promise firms the ability to respond to new opportunities quickly.

There are many successful eCommerce platforms today, so it’s fair to say that the two terms are interchangeable. Mobile phones have fueled a meteoric rise in usage. People use mobile applications for a wide range of purposes because they are more user-friendly than desktop websites.

This has had a significant impact on how organizations communicate with their customers. Brand-consumer connections used to occur primarily through mass media, but today ads are personalized to your interests and purchasing behavior.

Let’s understand the definition of microservices architecture for eCommerce

It is possible to swiftly design large-scale, scalable, and complicated digital applications using a microservices architecture. Small (micro) independent services are gathered under the umbrella of this umbrella organization. These APIs allow these eCommerce microservices architecture to share resources and communicate data.

Using Microservices architecture for eCommerce, large, complicated software systems can be broken down into smaller, more manageable components. More minor separate services are stacked together to provide the overall functionality of the business.

Small teams typically build and maintain Ecommerce microservices designed to provide a single business capability. Development teams responsible for specific microservices can utilize technologies to build a particular Microservices eCommerce Architecture because they are independent.

Allows organizations to launch new features and speed up innovation without affecting the overall application architecture Microservices are well-suited to agile development because of their design. Feature development, testing, and deployment can occur continually for businesses. Decoupling redundant features and microservices from the overall application is as simple as adding new features.

Microservices have several distinct properties

eCommerce microservices architectures are modest in size, grouped around fine-grained business capabilities, and hence their footprint is less than services in SOA.

  • Independent development, testing, and deployment are all possible because microservices are designed to be self-contained and decoupled from the rest of the system.
  • One-off — Microservices are created to address a single, narrowly focused issue or business capability. As the size of a microservice increases, it should be divided up into smaller ones.
  • All microservices connect via well-defined APIs and do not exchange any code.
  • Using microservices, it is feasible to scale up only those that support the functions with resource limits, which provides extra resource and cost optimization.
  • Microservices are network-agnostic and can communicate with each other regardless of the technology used. They commonly use protocols like HTTP or a message bus to achieve this.
  • With their independence, microservices can be implemented using a variety of programming languages (including Java), databases (including relational databases), and hardware and software environments. However, no single microservice will be a jumble of multiple programming languages, regardless of the technology used to build it.


What does the term scalable mean?

As the number of users and load increases, the web application must be able to handle it without disturbing the user experience and activities of the end-users.

Modern frameworks and technologies like Microservice architecture for eCommerce, PWA, cache, and cloud storage create scalable web applications that maintain their performance over time.

Let’s gear up to understand the best practices for developing large-scale eCommerce applications?

Scalability is an application’s ability to increase performance as more resources are added to the system.

It’s also crucial that the added resources improve performance proportionally. The app should be able to handle more demand if it has a better performance. When datasets expand, they can also manage more extensive and more complex projects.

A quick look into the eCommerce microservices architecture flow on significant platforms is provided here. The customer first logs into their account on the app. Customizable homepages for every single customer. This is because the website adapts to the user’s browsing and purchasing habits.

For apps to give a unique experience, ML algorithms understand the user’s patterns. When customers make a purchase decision, they add the item to their shopping cart. They are then taken to a page where they must submit their shipping and billing information. Final step: click “Confirm Order” to finish the transaction.

As well as increasing the capacity of servers and databases, scalability applies to application technologies. They must ensure that the technologies they utilize in developing their applications can be scaled and have a strong support network.

The application’s architecture is responsible for the overall structural order. The architecture is composed of: the frontend, backend, data, and the infrastructure it runs on. 

Moreover, scalability is a significant advantage of designing web apps

As your organization grows, you need to ensure that your apps handle it. From the start, prioritizing it offers numerous advantages, including increased business agility, lower maintenance costs, and a better Ecommerce customer experience.


Making the software scalable serves a variety of purposes. Let’s get started now!

Ensure the long-term success of your technology investment

You can keep using the same software for a longer time if you choose a scalable solution. This is because the program was built to expand with your organization.

Improve the overall experience for your app’s users

Your customers don’t like sluggish apps, as was previously stated. When it comes to purchasing, reserving a ticket, or looking for information online, they merely want to get the job done as soon as possible. They are also great for creating a positive Ecommerce customer experience because of their high-scalability architecture.

Performance improvements for the app

Web programs that can withstand sudden increases in users or workload are scalable. Conventional apps slow down when there is a spike in traffic, but not this one.

Continued expansion of the company

Long-term planning is out of the question in today’s quickly changing business and market environments. Scaling your web apps is the only way forward in today’s fast-changing business ecosystems.

Save money

It’s cost-effective in the long run to scale business-critical systems since it ensures company continuity even in the most unusual circumstances.

For eCommerce, what are the advantages of microservices?


Decoupled and headless techniques turn every microservice into an independent, powerful entity that can be easily integrated or removed from the Ecommerce platform and updated without affecting the entire Ecommerce microservices.

The ability to stay current and a focus on a specific subject

A dedicated dev team is responsible for the module’s testing, debugging, and asynchronous deployment for each Ecommerce microservices.


The usage of eCommerce microservices architecture enables rapid and effective data processing, timely updates, faster delivery to the market, and a quality user experience across all consumer interaction channels.

Maintenance expenditures are reduced

Smaller modules in Microservices eCommerce Architecture codebases save both development and maintenance expenses compared to monolithic design.

How is microservices architecture implemented for eCommerce applications?

Microservices architecture for eCommerce is a good fit for cloud-native eCommerce platform development. The eCommerce landscape and retail business, in general, are evolving quickly. New features are continuously introduced to drive engagement, sales, and customer loyalty. During the festive seasons, merchants face scalability challenges for exponential traffic spikes. eCommerce microservices architecture is a painkiller for all these challenges; for the omnichannel effective eCommerce platform exploiting microservices, serverless, beacon, AI, and data would be the right approach.

A not-so-complex multi-vendor eCommerce microservices architecture would consist of the independent product catalog, Modular eCommerce Solution, inventory microservices, cart, checkout and transaction microservices, and customer profiles microservices, ratings and reviews, and Vendor profile microservices. The client-facing UI interface itself could be an independent microservice and can be interfaced with an eCommerce microservices architecture to dynamically load UI elements and data via restful APIs.
