The client

Invoice.me, an online accounting software catering to SMBs, wanted to modernize their legacy monolith application. Their current Ruby on Rails codebase struggled with scalability and deployment complexity. They required an agile development approach and a robust cloud infrastructure to support their growing user base and feature demands.

The challenge

Invoice.me’s monolithic architecture hampered efficient development cycles. Feature deployments were cumbersome due to code dependencies, delaying time-to-market. Additionally, scalability limitations on their on-premise infrastructure couldn’t accommodate projected growth. They needed a solution that fostered faster development, improved scalability, and reduced infrastructure management overhead.

What was done

Ralabs completely refactored Invoice.me’s application into a microservices architecture. The codebase was divided into independent, self-contained services, each with its own API and database schema. This modular approach enabled parallel development and independent deployments, streamlining the development process and accelerating feature delivery. The application was migrated to a modern cloud infrastructure on AWS using Kubernetes for container orchestration. This shift provided elastic scalability, allowing Invoice.me to seamlessly scale resources to meet user demands.

Implemented features:

Microservices Architecture

Divided the application into independent, fault-tolerant services like “user management,” “invoicing,” and “payment processing,” enabling faster development and deployment.

Reactive API Gateway

Implemented a serverless API gateway built with AWS API Gateway to manage API calls and distribute them to the appropriate microservices.

Cloud-Native Infrastructure

Migrated the application to a cloud-based infrastructure on AWS for scalability, resilience, and cost-efficiency. Containerization with Kubernetes ensured smooth scaling and deployments.
