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.
The Migration Math Most Programs Get Wrong
Cloud migrations do not fail in the datacenter. They fail in the spreadsheet, when everything is marked lift-and-shift and the hard decisions are deferred to a future that never gets funded. Our migration discipline front-loads the math:
- Ruthless 6R triage: retire and retain are real answers, and saying them early is where the savings live.
- Landing zones before workloads: identity, networking, logging, and guardrails exist before the first server moves.
- FinOps from day one, with unit costs per workload visible weekly, because cloud waste compounds like interest.
- Exit criteria per wave: a wave is done when performance, cost, and security baselines are green, not when the cutover call ends.
We measure a migration by one question: is the organization more AI-ready at the end than the start? If not, it moved servers, not capability.
A disciplined migration is the difference between cloud spend and cloud advantage. Our modernization work builds the AI-ready foundation first, so every later initiative ships faster.
