The demand for virtual therapy sessions has surged in recent years, prompting OBS to architect a native, scalable video solution to enhance Theracuity’s capabilities and solidify its market leadership.
The Challenge
OBS was tasked with embedding real-time video therapy within the Theracuity platform, a critical enhancement that came with a stringent set of requirements:
- Unwavering HIPAA Compliance: Handling sensitive patient data necessitated an architecture that not only met but exceeded healthcare regulatory standards.
- Minimal Operational Overhead: The goal was to eliminate the burden and prohibitive costs associated with provisioning and managing traditional video conferencing servers.
- Robust Session Control: The system demanded sophisticated mechanisms for securely creating, joining, monitoring, and concluding sessions.
- Comprehensive Data Capture: The ability to record sessions and meticulously capture metadata (attendance, join/leave times, duration) was crucial for clinical documentation and future analytical insights.
- Elastic Cost-Effective Scaling: The solution had to scale seamlessly and efficiently to accommodate unpredictable demand fluctuations without escalating operational expenditures.
Existing third-party telehealth vendors presented significant limitations, including restrictive customization options, inflexible licensing models, and integration complexities that fundamentally clashed with OBS’s vision for a deeply integrated, intelligent EHR. This necessitated OBS’s deep expertise to engineer a bespoke, fully serverless, and AWS-native solution, aligning perfectly with our commitment to innovation and client-centric development.
The Solution
OBS engineered and implemented a fully serverless video session framework, leveraging the power of the Amazon Chime SDK. This innovative core solution combines Amazon Chime for real-time communication with a robust, custom-built backend utilizing AWS Lambda, SQS, and S3 for comprehensive session management, recording, and intelligent post-processing.
The architecture ensures that upon every appointment creation within Theracuity, a serverless function dynamically provisions a dedicated Chime meeting instance. This sophisticated backend orchestration enables therapists and patients to seamlessly join secure video sessions directly through Theracuity’s intuitive user interface, delivering a truly integrated experience.
The OBS development team, renowned for its expertise and led by Akinsola Oluwole, the visionary Lead Developer who spearheaded this groundbreaking module solution, meticulously ensured that this solution adhered to the most robust cloud-native patterns. His leadership and technical prowess were instrumental in seamlessly integrating this complex system into Theracuity’s existing backend microservices and frontend components, a testament to our commitment to architectural excellence and comprehensive integration.

Security and Compliance
At OBS, security and HIPAA compliance were not merely requirements but fundamental pillars guiding every design and implementation decision. Our approach ensures the highest standards of data protection:
- End-to-End Encrypted Communication: All video, audio, and metadata transfers within Amazon Chime are rigorously encrypted in transit using industry-standard protocols like TLS/SSL, safeguarding sensitive patient interactions.
- Precisely Scoped Credentials: Attendees are authenticated via dynamically generated tokens, meticulously scoped to each specific session. This ensures that access is strictly limited and temporary, minimizing potential vulnerabilities.
- HIPAA-Ready Infrastructure: The entire infrastructure and all data handling processes are meticulously aligned with HIPAA best practices. Recording storage leverages encrypted S3 buckets, and access policies are stringently enforced through fine-grained AWS IAM controls, providing an uncompromised secure environment.
- Robust Role-Based Access Control: Theracuity’s inherent role-based access control extends seamlessly to all telehealth features, guaranteeing that only authorized users can access specific functionalities and sensitive patient data, upholding the principles of least privilege.
