Overview
Transnet Cloud partnered with Food Online to modernize its cloud infrastructure on AWS, enabling reliable real-time order processing, secure payment handling, and scalable delivery operations across Lagos, Abuja, Port Harcourt, and Enugu.
The Challenge
Food Online's existing infrastructure struggled with real-time order processing, dynamic restaurant listings, and secure data management. Core challenges included payment transaction reliability during peak lunch and dinner windows, securing payment credentials and customer financial data, reliably managing multi-vendor settlement workflows, and delivering transactional communications at scale — all in a market where a single outage could send customers to a competing app.
Proposed Solution & Architecture
Transnet Cloud designed a containerized, security-first AWS architecture purpose-built for high-volume, real-time food ordering and payment processing.
Compute & Containerization
Amazon EC2
Docker container hosts across two Availability Zones within a custom VPC with public/private subnet separation
Amazon ECR
Private container image registry with native IAM-based access control, selected over ECS/EKS to match team size and operational familiarity
Database & Storage
Amazon RDS for PostgreSQL
Managed database for orders, users, and delivery logistics with Multi-AZ failover, automated backups, and point-in-time recovery
Amazon S3
Storage for restaurant menus, images, logs, and order archives with KMS encryption and lifecycle transition to Standard-IA after 90 days
Amazon EBS (gp3)
Storage volumes for the EC2 container host instances
Payment Reliability & Communications
Amazon SQS
Durable asynchronous queuing decoupling order submission from payment processing during peak lunch and dinner windows
Amazon SES
Transactional email delivery for order confirmations, payment receipts, and delivery notifications
Security & Monitoring
AWS Secrets Manager
Automatic rotation for payment gateway credentials, integration keys, and database passwords, eliminating hardcoded secrets
AWS KMS
Customer-managed keys encrypting financial data at rest across EBS and S3
Amazon CloudWatch
Monitoring of container health, SQS queue depth, and API response metrics
Amazon SNS
Operational alerting to the engineering team on infrastructure and application events
Amazon Route 53
DNS routing with health checks for automatic failover
Outcomes & Success Metrics
Measurable reliability and security gains for a high-volume food delivery and payment platform.
Zero payment transactions lost due to processing layer failures during peak ordering periods since deploying SQS-based asynchronous processing
100% of payment credentials managed in AWS Secrets Manager with automatic rotation, with zero credentials stored in code or container images
Transactional order confirmation emails achieve over 95% delivery rate to Nigerian consumers via Amazon SES
Reliable multi-vendor settlement and order processing supporting operations across Lagos, Abuja, Port Harcourt, and Enugu
TCO Analysis
Transnet Cloud modelled cost across compute, container management, payment processing, communication, security, and monitoring services, sized around a two-AZ container deployment.

Lessons Learned
The initial architecture used a self-managed database on EC2 rather than a managed RDS service, introducing manual maintenance overhead for a payment platform where database availability is critical. Transnet Cloud documented a migration roadmap to Amazon RDS for PostgreSQL, providing automated Multi-AZ failover, point-in-time recovery, and managed patching.
The initial Amazon ECR setup did not have image scanning enabled. This was remediated by enabling ECR enhanced scanning with Inspector integration to automatically scan container images for vulnerabilities on push — now a day-one configuration item for future engagements.
