Migrated legacy systems to AWS with secure API integrations and optimized cloud architecture.
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.
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.
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.
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.
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.
To satisfy strict regulatory requirements and establish stable processing under extreme transaction loads, we selected the following technologies:
