Premise

In today’s fast-paced e-commerce world, scaling an online store to handle millions of dollars in sales daily requires more than just subscribing to a platform like Magento or Shopify. While these services offer convenience, their costs and limitations become apparent as the business grows. Our client in Mexico City needed a robust, cost-effective, and scalable solution to support their rapidly expanding e-commerce operations.

Challenge

The client’s e-commerce platform faced significant hurdles as their sales volume skyrocketed. They needed to:

• Handle high traffic during peak sales events like Black Friday and Christmas.
• Improve database performance without excessive downtime.
• Scale seamlessly without causing session management issues.
• Optimize checkout processes to prevent payment failures.
• Develop a mobile app for an enhanced shopping experience.

Building a system that could efficiently manage these challenges while keeping costs under control was the primary goal.

Solution

To ensure a smooth and scalable experience, we implemented a step-by-step approach:

Step 1: Deploying Magento 2 Community Edition

• We launched a Magento 2 community edition on AWS as a foundation.
• Amazon CloudFront was used to cache static assets like images, videos, and scripts.
• A Java microservice was added to handle OTP-based authentication.

Step 2: Enhancing Database Performance

• The high CPU load on MySQL required us to migrate the database to Amazon RDS.
• This transition, completed in under 30 minutes, ensured high availability and automatic backups.
• The move helped the platform handle its first Black Friday seamlessly.

Step 3: Improving Session Management

• To allow scaling beyond a single Magento instance, we migrated session management to Amazon ElastiCache.
• Elasticsearch was introduced for optimized search and indexing.
• An auto-scaling AWS architecture was deployed to dynamically adjust resources based on demand.

Step 4: Streamlining Checkout with Microservices

• A Node.js-based checkout service was developed and hosted on a secure subdomain.
• Multiple payment gateways were integrated based on success rates and transaction fees.
• This reduced payment failures and improved user experience.

Step 5: Launching a Mobile Application

• A React Native mobile app was built using Magento 2 APIs.
• The app was developed and launched within one month, expanding customer accessibility.
