Infrastructure & Database Migration to AWS

Migrated legacy systems to AWS with secure API integrations and optimized cloud architecture.

SaaS Client Overview

SaaS Management Provider

The client provides resource management software for international logistics companies. Their legacy infrastructure was struggling with high maintenance costs and unpredictable downtime.

They sought a complete transition to a modern, cloud-native environment to support their expanding global user base.

Challenge

The transition faced several technical hurdles:

  • Legacy monolithic database that was difficult to shard.

  • Highly sensitive customer data requiring strict encryption and compliance.

  • The need for a 'zero-downtime' migration strategy to avoid disrupting global logistics.

  • Lack of automated deployment pipelines in the existing setup.

Migration Challenge
Cloud Goals

Main Goals

We targeted resilience and scalability:

  • Migrate all services to AWS with 100% data integrity.

  • Implement a containerized architecture using Docker and ECS.

  • Enable auto-scaling to handle variable traffic loads.

  • Build a fully automated CI/CD pipeline for rapid software updates.

Project Overview

We re-architected the monolith into a microservices-friendly structure. Using AWS RDS for the database and S3 for storage, we ensured that the application was decoupled and highly available.

Security was baked in using IAM roles, VPC subnets, and AWS Shield for DDoS protection.

Solution

Our solution involved a staged migration approach:

    Key Features

  • Infrastructure-as-Code (IaC) setup using Terraform.

  • Blue-Green deployment strategy to ensure zero downtime during cutover.

  • Centralized logging and monitoring via CloudWatch and ELK stack.

  • Enhanced security protocols for data-at-rest and data-in-transit.
