High-availability telecom eCommerce platform for product sales and account services

The Need

Robi Axiata, one of Bangladesh's largest mobile network operators serving millions of subscribers, needed a robust online store to manage telecom product sales and account services at massive scale.

Their existing digital commerce infrastructure couldn't handle the demanding requirements of telecom eCommerce—where product offerings change rapidly with new devices and plans launching frequently, promotional campaigns drive massive traffic spikes, and customers expect 24/7 availability for purchasing devices, activating services, and managing accounts.

Robi required a high-availability eCommerce platform capable of supporting 1,000,000+ monthly active users with 100% platform uptime guaranteed, as even brief outages would result in significant revenue loss and customer dissatisfaction.

The challenge was to build a telecom eCommerce platform that could handle concurrent users during flash sales and campaign launches, adapt quickly to evolving offers and marketing needs through customized back-office tools, provide integrated analytics for real-time insights into platform performance, and maintain seamless operation under heavy load while supporting both product sales (smartphones, modems, accessories) and account services (plan activations, recharges, upgrades).

With telecom customers expecting instant gratification and competitors just a click away, Robi needed an enterprise-grade platform that would never go down and always perform.

The Solution

We developed a high-availability telecom eCommerce platform that has become the cornerstone of Robi Axiata's digital sales strategy, reliably serving over 1,000,000 monthly active users with guaranteed 100% uptime.

The Telecom eCommerce Platform delivers a high-availability online store specifically built for Robi Axiata to manage telecom product sales and account services.

The platform handles diverse product categories including smartphones from multiple manufacturers, mobile broadband modems and routers, SIM cards and starter packs, accessories like chargers and cases, and digital products like plan activations and service upgrades.

Account services enable customers to view and manage their Robi accounts, check usage and billing, recharge prepaid accounts, upgrade to new plans, activate add-on services, and access customer support—all integrated within the eCommerce experience.

The high-availability architecture ensures customers can purchase products and manage accounts 24/7 without interruption, critical for maintaining competitive advantage in Bangladesh's highly competitive telecom market.

The Scalable Performance component implements robust system architecture designed to support high numbers of concurrent users with seamless uptime.

The platform employs load balancing distributing traffic across multiple servers to prevent any single point of failure, database replication ensuring data availability and query performance even under heavy load, caching strategies reducing database load and accelerating page load times, auto-scaling capabilities automatically adding resources during traffic spikes, and redundant infrastructure with failover mechanisms ensuring continuous operation even if individual components fail.

This architecture enables the platform to handle normal operations comfortably while scaling seamlessly during promotional campaigns that drive traffic surges—flash sales, new device launches, or major marketing events—without performance degradation or downtime.

The Customized Back Office provides tailored inventory and admin tools enabling Robi's team to quickly adapt to new offers, marketing campaigns, and operational changes.

The back-office system includes inventory management tracking stock levels across warehouses and retail locations, product catalog administration for adding new devices, updating specifications, and managing variants, pricing and promotion engines for configuring discounts, bundle offers, and flash sales, order management workflows for processing purchases, coordinating deliveries, and handling returns, customer service tools for managing accounts, resolving issues, and tracking support tickets, and content management for updating banners, landing pages, and product descriptions.

This flexibility ensures Robi can respond rapidly to market opportunities—launching new device offers within hours, adjusting pricing in response to competition, or creating targeted promotions for specific customer segments—without requiring technical development cycles.

The Integrated Analytics feature provides built-in usage tracking and reporting for real-time insights into platform performance.

Dashboards show key metrics including transaction volumes and values, conversion rates by product category, traffic sources and user journeys, popular products and search terms, cart abandonment rates and friction points, and system performance metrics.

These analytics enable data-driven decision-making, helping Robi optimize product offerings, improve user experience, identify technical issues proactively, and measure campaign effectiveness.

The platform's success is demonstrated by its massive scale and reliability: serving 1,000,000+ monthly active users while maintaining 100% platform uptime guaranteed, ensuring Robi's digital commerce operations never falter even as the business grows and customer expectations rise.

The Challenge

The primary challenge was architecting a platform that could guarantee 100% uptime while serving 1,000,000+ monthly active users—a reliability requirement that demands sophisticated infrastructure, redundancy, monitoring, and operational practices.

Even brief outages would impact revenue, damage brand reputation, and drive customers to competitors, making high availability non-negotiable rather than aspirational.

Building scalable performance that could handle massive traffic spikes during promotional campaigns required careful capacity planning and elastic architecture.

Telecom flash sales for popular devices can drive traffic surges of 10x or more within minutes, and the platform needed to scale smoothly without crashes, slowdowns, or transaction failures. Balancing cost-efficiency during normal operations with over-provisioning for peak load scenarios presented significant architectural challenges.

Creating a customized back office that was flexible enough to accommodate rapidly changing telecom offers while remaining user-friendly for non-technical staff required sophisticated admin interface design.

Telecom products involve complex attributes (device specifications, network compatibility, plan terms), dynamic pricing (promotional rates, bundle discounts, loyalty pricing), and frequent updates (new devices, plan changes, regulatory requirements). The back office needed to support this complexity without becoming overwhelming or error-prone.

Implementing integrated analytics that could provide real-time insights from massive transaction volumes while maintaining platform performance required careful data architecture.

Analytics queries on large datasets can impact application performance if not properly isolated, yet business users needed current data for decision-making. Building analytics infrastructure that delivered timely insights without compromising customer-facing performance required technical sophistication.

Ensuring seamless account services integration connecting the eCommerce platform with Robi's billing systems, customer databases, and service provisioning platforms required robust API design and careful handling of sensitive customer data.

Account management operations needed to be secure, reliable, and instant, as service activation delays or billing errors directly impact customer satisfaction.
