At ABCloudz, we specialize in helping businesses modernize their legacy applications to improve performance, scalability, and user experience. This month, we’re excited to showcase how we transformed an outdated payment platform and a legacy marketing system into modern, scalable solutions.
From revamping frontends for better usability to implementing DevOps best practices and transitioning to microservices, these projects highlight our expertise in application modernization.
Modernizing a legacy payment platform
Phase 1: Re-platforming the frontend for faster value realization
The first step in modernizing a legacy payment platform was enhancing the user experience without disrupting backend operations. We replaced the outdated WebForms-based UI with a React-powered frontend, improving usability and merchant-facing tools. This strategic approach allowed our client to start generating revenue from modernization efforts early on, rather than waiting for a full-scale system overhaul while continuing to invest without returns. A Proxy API was introduced to seamlessly connect the new frontend with the legacy backend, laying the foundation for future architectural upgrades.

Phase 2: Building CI/CD pipelines for micro-frontend and microservice deployment
With the frontend re-platformed, the next step was transitioning to micro-frontends and microservices for greater flexibility and scalability. To support this transformation, we introduced a CI/CD pipeline built on Kubernetes, Rancher, and GitLab CI/CD. This pipeline automated deployments, reduced downtime, and provided a seamless transition to a distributed architecture.

Phase 3: Breaking the monolith into micro-frontends and microservices
This phase focused on transforming the tightly coupled architecture into independently deployable frontend modules and backend microservices. Using Webpack Module Federation, Shadow DOM, and Kubernetes-based microservices, we created a scalable, future-ready platform that accelerates development cycles while ensuring operational stability.

Modernizing a legacy marketing system
For another client, we rebuilt an outdated marketing system using a modern architecture based on microservices, real-time inventory tracking, and automated workflows. The result? A scalable, high-performance system that optimizes campaign management and boosts efficiency.
