R&T Deposit Solutions, a leading innovator in financial services specializing in multi-bank deposit sweep networks, partnered with Caylent to migrate its existing systems to a modern, cloud-native AWS architecture designed for scalability and resilience. The transformation replaced constrained on-premises infrastructure with a flexible, cloud-native platform supporting 10x transaction growth, multiregion disaster recovery, and fully automated CI/CD operations. By incorporating synthetic data generation and containerized workloads on Amazon ECS, R&T built a high-performance foundation capable of scaling the number of participating banks by 3–5x while upholding regulatory rigor and enabling AI-driven innovation in deposit management.
→ Cloud-Native Platform Modernization: Migrated existing systems to a scalable AWS-based architecture designed to support exponential transaction volume increases.
→ Multi-Region Resiliency & Automation: Implemented infrastructure as code, CI/CD automation, immutable data copy, and multi-region disaster recovery to ensure high availability and regulatory-grade reliability.
→ Synthetic Data & Scaled Testing Engine: Built a generative AI-powered synthetic data framework to model client growth scenarios and stress test the platform at 10x workload levels.
→ Unified Post-Merger Architecture: Consolidated and standardized two technology stacks into a harmonized, enterprise-grade cloud-native environment.
→ 30% Performance Improvement: Increased database and application server performance by 30% through optimized cloud-native architecture and synthetic workload modeling.
→ Strengthened Security & Governance Posture: Leveraged AWS-native tooling to modernize infrastructure management and improve security controls.
→ 15x Customer Growth Capacity: Positioned the platform to support adoption by 10–15 times more institutions while maintaining compliance and resiliency.
→ Access to Expanded Federal Deposit Insurance Corporation (FDIC) Coverage for Customers: Enabled institutions to offer access to expanded, multi-million-dollar FDIC deposit insurance coverage with greater efficiency, transparency, and faster onboarding.
“Caylent has exceeded our expectations as a partner. They understand and believe in our mission, bring high-caliber engineers and project managers to the table, and match our sense of urgency. The quality of their work and governance has been outstanding.”

Founded in 1974, R&T Deposit Solutions is a leading innovator in financial services, specializing in multi-bank deposit sweep networks that help financial institutions optimize liquidity and maximize FDIC deposit insurance coverage for retail customers. They are a trusted partner to more than 350 financial institutions, providing resilient deposit and funding solutions that help institutions grow, optimize capital management, and safeguard customers’ funds.
Banks today face mounting pressure in managing uninsured deposits, particularly in the wake of recent financial crises. Large balances that exceed FDIC insurance limits increase liquidity risk and attract heightened regulatory scrutiny. At the same time, the acceleration of digital banking has fundamentally changed deposit behavior, making bank runs faster and customer confidence more fragile. Institutions must protect client relationships while managing balance sheet pressures, rising compliance expectations, and persistent cybersecurity threats. Together, these forces are reshaping the deposit landscape, driving the need for greater transparency, resiliency, and operational agility.
As demand for access to expanded FDIC deposit insurance coverage increased, regulatory expectations for enhanced reporting intensified, and the competitive landscape shifted toward technology-enabled financial services, the limitations of the existing infrastructure became clear. R&T needed to modernize its platform to handle substantially higher transaction volumes, enable real-time, multi-region processing, and unlock advanced analytics, all while maintaining the highest standards of customer data privacy and regulatory compliance.
R&T needed far more than a lift-and-shift migration. It required a strategic modernization effort that balanced scalability with governance and innovation with compliance.
Caylent partnered with R&T to migrate its existing systems to a cloud-native AWS architecture designed for scale, resiliency, and operational agility. Two post-merger technology stacks were consolidated into a standardized, enterprise-grade environment powered by elastic compute and automated infrastructure.
Development and testing leveraged Amazon EC2 instances accessed via SSM tunnels, enabling on-demand changes in memory and processor resources by restarting machines—a flexibility that physical workstations did not offer. Multi-region disaster recovery was established with advanced CI/CD automation and immutable data copy. These changes eliminated existing tooling, simplified infrastructure management, and unlocked a faster pace of iteration.
A key accelerator in the transformation was the development of a synthetic data generation engine powered by generative AI. This solution enabled R&T to simulate realistic client portfolio scenarios and validate system performance under extreme growth conditions. Instead of relying solely on historical data, the organization can now proactively model future scale and regulatory complexity.
The performance impact was immediate. Database and application server performance improved by 30% during daily operations, and the platform was successfully stress-tested at 10 times the normal workload. This validated readiness for exponential institutional growth and gave leadership confidence that the system could scale to support 10-15 times more customers without compromising reliability.
The architecture also enabled AI innovation, including smarter deposit allocation and optimization, predictive liquidity and cash management, and personalized client insights and digital experiences.
By migrating to AWS, R&T unlocked a pace of innovation that was not achievable with on-premises technology. Institutions now benefit from faster onboarding, access to expanded FDIC deposit insurance coverage with greater efficiency and transparency, and self-service access to real-time data. Internally, R&T turned regulatory and liquidity complexity into a data-driven advantage, positioning the organization to anticipate growth rather than react to it.
R&T’s modernized platform runs on AWS-native infrastructure using Amazon EC2, Kubernetes, and Kafka to support rapid iteration and flexible development. Development environments use EC2 instances accessed via AWS Systems Manager (SSM), enabling on-demand changes in memory and processor resources by restarting machines. As the platform evolves, R&T is expanding its use of Amazon ECS, Amazon EventBridge, and AWS Lambda to reduce operational costs and deliver improved product scaling and compute agility. Amazon S3 underpins the application's storage needs, and for AI-driven capabilities, R&T leverages Amazon Q Developer with Claude models for data format analysis and synthetic data generation, and it uses Claude on Amazon Bedrock to validate data outputs against strict specifications—ensuring a scalable, AI-ready foundation.
