How a growing technology platform moved from a shared default VPC to a secure, production-ready AWS architecture
As the company’s containerized workloads and data-intensive services grew, its shared default VPC created security, isolation, monitoring, and scalability constraints. Flentas migrated the platform into dedicated AWS environments, separating staging and production while modernizing compute and databases and strengthening security controls—all in just three weeks with minimal business disruption.

The Challenge
A shared AWS environment creating security and scalability risks
The company's default VPC had become a constraint as the platform grew, making it harder to separate environments, secure workloads, and gain visibility into infrastructure performance.
No environment isolation
Staging and production workloads shared the same network environment.
Security gaps
Web protection, secrets management, threat detection, and configuration monitoring were not comprehensively implemented.
Limited observability
The absence of centralized dashboards and enhanced database monitoring made performance issues harder to identify.
Scalability constraints
The existing architecture wasn't designed to support the platform's longer-term growth.
The Approach
A dedicated AWS architecture built for isolation, security, and scale
Flentas redesigned the environment around clear separation between workloads while modernizing the underlying infrastructure.
- 01
Created dedicated VPCs for staging and production, providing complete network isolation and environment-specific controls.
- 02
Migrated containerized applications to Amazon ECS Fargate and upgraded PostgreSQL to Amazon Aurora PostgreSQL for greater scalability and availability.
- 03
Implemented layered security using AWS WAF, GuardDuty, AWS Config, VPC Flow Logs, least-privilege IAM, and AWS Secrets Manager.
- 04
Centralized observability through CloudWatch dashboards, database monitoring, and SNS alerts, while optimizing content delivery through CloudFront and S3.
