Use Case

PoC to Production for a CSV Processing App

A real-life scenario of taking a client's PoC/Staging application to a production-ready state on DigitalOcean.

The Challenge

A client had a working Proof of Concept application for manipulating large CSV files for a niche market. While the application was functional, it was running in a staging environment and lacked the robust infrastructure, automation, and reliability needed for a production launch. The goal was to move to a production-safe environment without incurring massive costs or complexity.

The Solution

M3tech was brought in to design and implement a production-ready environment on DigitalOcean. The solution focused on leveraging managed services, implementing Infrastructure as Code (IaC), and setting up CI/CD pipelines for seamless deployments.

Tech Stack & Architecture:

  • Frontend: React
  • Backend: Python
  • Database: Managed MariaDB (DigitalOcean)
  • Cache: Redis
  • Object Storage: Minio S3
  • Queue/Messaging: RabbitMQ
  • Notifications: Websocket events
  • Orchestration: Docker Swarm (3 nodes)
  • Log Centralization: Graylog7

Project Highlights:

  • Cost-Effective Orchestration: Docker Swarm was chosen over Kubernetes to meet the client's needs without the overhead of a complex orchestration system.
  • Infrastructure as Code (IaC): Full infrastructure provisioning and deployment automation, ensuring consistency and reliability.
  • CI/CD: Two distinct CI/CD pipelines were set up to automate the build, test, and deployment processes.
  • Centralized Logging: Graylog7 was implemented for efficient log centralization and monitoring of containerized services.

Infrastructure Cost

The project was successfully delivered within the 4-week timeline and under budget. The client received:

  • A production-ready, scalable, and cost-effective environment on DigitalOcean.
  • Complete documentation of the infrastructure and deployment processes.
  • All infrastructure code and deployment scripts in a GitHub repository.
  • A training session for their senior developer to ensure a smooth handover and operational ownership.
