The Client
Jamsan Management is New England based hotel & asset management company, which is recognized by its investors, franchisers and clients as quality intensive. Jamsan owns & manages a wide variety of properties in the North East United States. They work with all the leading national brands such as Hilton, Marriott International, Choice Hotels, Best Western International and Intercontinental Hotel Group to provide a unique lodging solution for the greater New England region.
Problem Statement
Prior to modernizing their backend systems, Jamsan faced persistent infrastructure challenges. The organization experienced frequent application downtimes, slow request handling, and performance issues tied to their legacy infrastructure. These shortcomings led to service unavailability, delayed responses to both internal users and external partners, and mounting operational costs. The need for a highly available, fault-tolerant, and cost-effective system became imperative—especially in light of the company’s need to process growing volumes of backend operations including guest media management, reservation triggers, session cleanup, and real-time data updates.
Furthermore, Jamsan, as one of the region’s most prominent property managers, was increasingly becoming a target for potential cybersecurity threats. Their digital ecosystem required a hardened, resilient architecture with strict adherence to security best practices and regulatory compliance. Manual infrastructure provisioning and monitoring were no longer feasible. The company sought a way to embrace cloud-native practices, reduce its operational footprint, and deliver consistent, high-quality service across all its properties.
Solution Provided by Hallmark (Powered by AWS Lambda):
To address these pain points, Hallmark designed and implemented a comprehensive, serverless architecture using AWS Lambda. By transitioning to an event-driven, stateless compute model, Jamsan was able to eliminate the burden of server management entirely. All critical backend processes were reimagined as modular, scalable Lambda functions.
The new solution integrates several AWS services including Amazon S3 (for file uploads and media management), Amazon DynamoDB (for session and file metadata), Amazon API Gateway (for secure access and request routing), and AWS Lambda (as the core compute service). Functions were built and deployed using AWS SAM (Serverless Application Model), enabling infrastructure-as-code, consistency across environments, and ease of deployment.
The following key workloads were migrated to Lambda:
- Image processing and tagging for uploaded media (e.g., hotel photos)
- Scheduled session cleanup tasks to free resources
- Real-time updates for internal property management dashboards
- Handling reservation system hooks and confirmation flows
Each Lambda function automatically scaled based on incoming traffic, whether invoked by an API request, an S3 PUT event, or a scheduled CloudWatch rule. No idle compute was required—Jamsan only paid for what they used, optimizing costs while improving responsiveness.
Security Architecture and Operational Visibility: Security was embedded throughout the solution. IAM roles were designed with least-privilege permissions for each Lambda function. Sensitive environment variables were encrypted and stored in AWS Systems Manager Parameter Store. Logs and performance metrics were routed to Amazon CloudWatch, enabling near real-time monitoring and anomaly detection.
IAM Access Analyzer helped detect overly permissive policies
All data stored in S3 was encrypted using AWS KMS.
Logging and alerting were established through CloudWatch and SNS
Runtime monitoring and debugging were supported with AWS X-Ray (in future plans).
Business Impact and Outcomes:By adopting this Lambda-powered serverless infrastructure, Jamsan realized significant and measurable improvements:
90% reduction in infrastructure maintenance — server provisioning, patching, and scaling were no longer required.
Near-zero downtime — as Lambda automatically scaled with traffic.
Cost savings — due to usage-based billing at millisecond granularity.
Accelerated development — teams were able to push updates faster using AWS SAM.
Improved observability — through native AWS logging and monitoring tools.
Most importantly, the new platform allowed Jamsan to serve its hotel guests, investors, and franchise partners more efficiently by focusing on core business innovation rather than IT overhead. The solution was robust, scalable, secure, and aligned with AWS Well-Architected Framework principles. It positioned Jamsan to rapidly respond to future needs with confidence in their cloud infrastructure.
This Lambda-first approach was not just a technical success but a strategic milestone in Jamsan’s broader digital transformation journey.
