Picking ecommerce architecture: Fundamental decision you need to make right

The type of your ecommerce architecture can define your online store’s success. What essential elements create a robust ecommerce infrastructure, and how do they impact your business’s growth and customer satisfaction? We tackle these questions by analyzing the critical elements: frontend, backend, and data storage, revealing their combined role and place in the bigger structure.

Key takeaways

  • Ecommerce architecture consists of frontend presentation, backend business logic, and data storage, with each playing a critical role in providing a seamless and scalable customer experience.
  • Modern ecommerce architectures like microservices, composable, and headless commerce allow businesses to be more agile and innovative, moving away from the limitations of traditional monolithic structures.
  • Utilizing modern tools that embrace headless and composable architectures enables businesses to create customizable, efficient, and future-ready ecommerce systems that adapt to market changes and integrate new technologies quickly.

Building blocks of ecommerce architecture

At the heart of every successful ecommerce store is a solid ecommerce site architecture, the critical framework that supports every customer interaction, transaction, and experience. Solution architects understand that the architecture is more than a design; it’s the foundation that enables an ecommerce store to function effectively.

Comprising frontend, backend, and data storage components, this ecommerce project architecture is a trio of functionalities that work together to create a seamless customer experience. Each element, from the user interface to the business logic and data repositories, is essential in the ecommerce operation.

The frontend: The role of user interface in ecommerce

The frontend is where customers first interact with an ecommerce store. It’s the presentation layer that provides visual appeal and ease of navigation, playing a vital role in customer experience and sales. The frontend is where the user experience unfolds, inviting customers to engage with the store.

A quality user interface is crucial for creating an experience that helps customers easily find and purchase products. It involves using ecommerce software architecture to streamline processes such as inventory management and optimizing for search engines. The balance between appearance and usability is what makes an online store effective.

The backend: Business logic

The backend is where the ecommerce website's core functions operate. It's where data processing and transactions take place, inventory levels are managed, and orders are processed efficiently. The backend is the support system of the ecommerce operation, ensuring that all functions, from payment processing to order fulfillment, run smoothly.

A robust ecommerce architecture design improves the platform’s performance, scalability, and security. It allows for adjustments to the system to meet changing business needs and market conditions, keeping the backend reliable and innovative.

Data Storage: Keeping customer data safe and accessible

In ecommerce, data is crucial. Data storage is responsible for safeguarding customer information and business insights. It ensures sensitive data is protected and only accessible to authorized users, maintaining customer privacy.

For example, Alokai Cloud offers the following features:

  • Scalability and security
  • Geofencing
  • DDoS protection
  • Automatic daily backups
  • Compliance with security standards such as ISO & GDPR
  • Alokai Cloud ensures your ecommerce store’s data is secure and efficiently managed.

Exploring different ecommerce platform architectures

There are several common ecommerce architectures, each with its own set of strengths and weaknesses. The choice between a monolithic ecommerce architecture, agile microservices, or adaptive composable architecture can significantly influence the trajectory of an online business. This decision hinges on factors like scalability, customizability, and cost-effectiveness, which guide businesses toward the architecture that best matches their vision and strategy.


Transitioning from monolithic systems

Shifting away from monolithic architecture means recognizing the limitations that have historically restricted businesses to a single, cumbersome codebase. Such traditional systems can inhibit innovation and slow a business's ability to adapt to the evolving ecommerce environment. Monolithic structures can act as barriers to growth, locking companies into a single service provider and hindering rapid response to market demands.

Embracing more flexible and scalable architectures is a strategic move that has become essential for survival in a marketplace where customer experiences and operational agility are crucial.

Microservices and composable architecture

The adoption of microservices architecture represents a new direction for ecommerce businesses. This approach involves breaking down the ecommerce system into small, independent services that communicate through APIs. Microservices and composable architectures offer the flexibility to quickly respond to market changes and develop new services based on customer needs, supporting a resilient digital commerce ecosystem.

Businesses adopting these architectures can enjoy the freedom to expand and innovate, ensuring their ecommerce platforms stay competitive.

Headless commerce architecture

Headless commerce architecture separates the frontend from the backend, allowing developers to create user experiences without the constraints of traditional systems. This architecture enables a more responsive platform customized to the needs of today's consumers.


Headless commerce is a significant shift that enables businesses to redefine customer engagement. By supporting flexible frontends and omnichannel sales strategies, headless architecture places ecommerce ventures at the leading edge of the market.

Benefits of headless commerce

The separation of frontend and backend in headless commerce provides several advantages:

  • It enables brands to innovate and try new customer experiences.
  • It offers the agility to update the frontend without impacting backend operations.
  • It fosters rapid innovation and helps businesses stay competitive.

Additionally, the robust infrastructure of a headless system, focusing on fault tolerance and service availability, contrasts with the challenges of monolithic systems. It serves as a foundation for resilience, ensuring that ecommerce platforms can meet the demands of the digital age while delivering outstanding customer experiences.

Success stories with headless solutions

Examples of successful headless commerce implementations can be more illustrative than theoretical discussions. Brands like White Stuff and Zadig & Voltaire have transformed their ecommerce platforms using technologies like Alokai, improving extensibility and overcoming performance challenges.

White Stuff has streamlined customer experiences through digital transformation, while Zadig & Voltaire achieved a 72% increase in mobile conversions, demonstrating the effectiveness of headless commerce.

Crafting a scalable ecommerce architecture

In the competitive world of ecommerce, scalability is a key factor, ensuring that an online store can adapt to a growing audience. A scalable ecommerce architecture is crucial to a business’s ability to innovate and expand without being hindered by performance limitations or outdated systems. It is vital for long-term success and avoiding future system bottlenecks.

Evaluating an ecommerce site’s architecture for scalability is important in planning for growth and expansion without affecting the performance of the digital storefront. It involves choosing an architecture that aligns with long-term business goals and allows continuous improvement.

Selecting the best architecture for your needs

Choosing the right ecommerce architecture requires careful consideration of the business’s needs and objectives. The decision should be based on finding a solution that fits the company's requirements and strategic plans. It is important to avoid unnecessary complexity and expense while ensuring that the architecture meets non-functional requirements and supports sustained success.

While headless architecture is modern, it is not suitable for every business. To ensure a successful outcome, it is essential to evaluate the company's digital maturity and development capabilities before adopting headless commerce.

Ensuring room for expansion

As the ecommerce landscape grows, scalable architectures like headless and composable commerce become important for businesses exploring new markets. These architectures allow for growth and the ability to adapt to market changes without being constrained by monolithic systems.

Modern ecommerce systems, whether two-tier, three-tier, or composable architectures, provide security and performance while allowing for easy integration with other technologies. Scalability is an integral part of a well-designed ecommerce architecture.
