About Client

As a leading e-commerce platform in the fashion industry, Modivo has experienced rapid growth, bringing significant challenges in terms of scalability, system performance, and the speed at which new features could be delivered to the market. The existing monolithic architecture, which had initially supported the platform well, began to show its limitations as the user base expanded and the complexity of operations increased.

About the project

The primary goal of this project was to overhaul the existing architecture, focusing initially on the shopping cart module—an essential component of the Modivo platform that directly impacts customer experience and revenue generation. The objective was to transition this critical part of the system to a distributed architecture, allowing for better scalability, improved performance, and more agile development processes.

Technologies

Challenges

The architectural transformation posed several significant challenges:

1. Technological Adaptation: Transitioning to a distributed architecture required the team to adopt and master new tools and technologies. This included containerization, microservices architecture, orchestration tools like Kubernetes, and advanced monitoring systems. The team needed to ensure that these technologies were seamlessly integrated with existing systems and that all stakeholders were adequately trained to manage and develop within this new environment.
2. Process Overhaul: The shift from a monolithic to a distributed architecture required a complete redesign of the development and deployment processes. The team had to move from a central, linear development process to a more decentralized, iterative approach that allowed for independent development and deployment of microservices. This required not only technical adjustments, but also a culture change within the development team to embrace new workflows and methods of collaboration.
3. Scalability and Performance: One of the main drivers of this transformation was the need to improve the scalability and performance of the Modivo platform. The shopping cart module, being a high-traffic component, had to cope with increasing load without compromising performance. The new architecture had to ensure that the system could scale horizontally to manage peaks in traffic, especially during sales events or promotional periods.
4. Legacy System Integration: A significant challenge was the need to integrate new, distributed components with existing legacy systems. Ensuring compatibility and seamless data flow between new microservices and legacy parts of the system was crucial to avoid service disruptions.

Solution and Implementation

The transformation was carried out in several phases, with an experienced IT team taking the lead on the shopping cart module:

1. Microservice Design: The first step was to split the monolithic shopping cart module into independent microservices. Each microservice was designed to handle a specific function, such as product selection, price calculation, stock check, and payment processing. This modular approach allowed each service to be developed, tested, and deployed independently, increasing agility and reducing the risk that errors would impact the entire system.
2. Containerization and Orchestration: The microservices were configured as containers using Docker, enabling consistent and portable environments from development to testing to production. Kubernetes was implemented for orchestration, providing automation for deploying, scaling, and managing containerized applications. This configuration ensured that the system could dynamically adapt to changing workloads, maintaining high performance even during peak periods.
3. Continuous Integration and Continuous Deployment (CI/CD): A robust CI/CD pipeline was established to support the new development process. This enabled rapid iteration, with automated testing and deployment processes, ensuring that new features were delivered to production quickly and reliably. The CI/CD pipeline also facilitated frequent updates and improvements to the shopping cart module without downtime.
4. Advanced Monitoring and Analysis: With the move to a distributed architecture, monitoring and analysis became essential. The team implemented advanced monitoring tools to track the performance of each microservice, identify bottlenecks, and ensure system health. Real-time analytics provided insights into user behavior and system performance, allowing for proactive tuning and optimization.
5. Integration with Legacy Systems: The new microservices were integrated with legacy systems using APIs and middleware solutions that facilitated seamless communication between the old and new components. This ensured platform continuity without interruption during the transition period.
6. Increased Scalability: The platform can now scale horizontally to support an increasing number of users without compromising performance. This is especially important during high-traffic periods, such as sales events, where the shopping cart module plays a key role in generating revenue.
7. Performance Improvements: The distributed architecture and microservice approach have improved the performance of the entire platform. The shopping cart module now operates much more efficiently, providing faster response times and a smoother user experience.
8. Accelerated Feature Delivery: The implementation of CI/CD practices has significantly reduced the time it takes to develop and deploy new features. This agility allows Modivo to respond faster to market needs and continuously improve the customer experience.
9. Operational Resilience: The new architecture has improved the overall resilience of the platform. By isolating microservices from each other, problems in one component do not affect the entire system, reducing the risk of downtime and improving the stability of the platform.
10. Prepared for the Future: The transformation has enabled Modivo to be better prepared for future developments and technological advances. The platform is now more adaptable, able to integrate new technologies and scale as the business grows.

Challenges

Integration with an external partner for the purpose of settling affiliate transactions. Due to the long time needed to implement our own solution, a decision was made to use a product from an external company.

The product license assumed settlement based on the actual generated turnover, so it was necessary to generate and send lists of sold offers using an external company’s product.

Soltions

The team delivered a solution that periodically sent reports based on transaction events to an external partner.

The solution was independent, consistent with the accepted practices and technologies used in Allegro and did not involve other Allegro teams.

As a result, the team quickly produced and took over maintenance of an automatic solution that replaced the manual work of accounting departments.
