Case Study

Challenge: Modernizing Federal IT Infrastructure

The Office of Child Support Services (OCSS) operates several mission-critical federal systems and databases that assist Child Support Agencies and key stakeholders, including federal and private partners. To enhance operational efficiency and reduce costs, OCSS developed an IT Roadmap to migrate its legacy mainframe systems to a modern cloud infrastructure. This migration aimed to leverage emerging technologies, ensure scalability, and optimize system performance while maintaining compliance and security.

Corteq Solutions & AWS Collaboration: Enabling a Secure Cloud Transition

Corteq Solutions partnered with OCSS to facilitate a phased cloud migration strategy, transitioning core applications and databases to Amazon Web Services (AWS). Our approach focused on enhancing system resilience, securing data, and optimizing cloud resources for cost-effective and scalable operations.

To ensure a seamless transition, Corteq Solutions deployed a multi-tier cloud architecture with:

Management Virtual Private Cloud (VPC): Overseeing security, governance, and operational controls.
Production VPC: Hosting mission-critical applications with redundant architecture for high availability.
Transit VPC: Optimizing network performance, minimizing latency, and directing traffic efficiently.

All AWS infrastructure components were replicated across multiple Availability Zones, ensuring continuous operations even in the event of an outage. Applications were hosted within private subnets with controlled ingress and egress, safeguarding OCSS systems from external threats.

Technology Stack: Cloud Security, Resilience, and Performance Optimization

To support OCSS’s modernization goals, Corteq Solutions leveraged advanced cloud-native tools and security frameworks:

Cloud Security & Compliance

AWS GuardDuty & Security Hub – Continuous monitoring for threats and compliance adherence
AWS Key Management Service (KMS) – Encrypted data protection and secure access control
AWS Config & Secrets Manager – Policy enforcement and secure credential management

Cloud Infrastructure & Automation

Amazon S3 & Kinesis – Scalable storage and real-time data streaming
AWS Lambda & API Gateway – Serverless automation and secure API management
Amazon DynamoDB – High-performance data processing for OCSS applications
AWS CloudTrail & CloudWatch – Centralized logging, monitoring, and incident response

Customer Benefits: Scalable, Secure, and Cost-Effective IT Operations

The Corteq Solutions cloud migration framework provided OCSS with significant operational improvements, including:

High Availability & Disaster Recovery: Multi-Availability Zone replication ensures continued system uptime, even in case of infrastructure failures.
Enhanced Security Posture: Applications hosted in private subnets with firewall-protected access mitigate cybersecurity risks.
Optimized Network Performance: A Transit VPC reduces latency and enables efficient routing for federal agency users.
Operational Efficiency & Cost Savings: Automated cloud management reduces infrastructure overhead while improving system scalability.

Conclusion: Driving IT Modernization for Government Agencies

By integrating cloud-based automation, AI-powered security, and scalable AWS infrastructure, Corteq Solutions successfully modernized OCSS’s IT environment—reducing operational costs, strengthening security, and enhancing service delivery. Our federal cloud solutions empower agencies to transition from legacy systems to modern, resilient cloud architectures with minimal disruption.
