Amazon DynamoDB–Based Architecture for a Property Management Platform
Case Study Short Description
KTM One partnered with a renowned property management platform to modernize its core application using AWS. By implementing a serverless architecture with DynamoDB, Lambda, API Gateway, S3, and CloudFront, the platform now handles high volumes of property, tenant, and billing data with low latency, strong transactional integrity, and minimal operational overhead.
Client Overview
The customer is a Nepal-based property management platform that helps property owners and managers streamline day-to-day operations. From tracking tenants and billing to managing maintenance requests, the platform provides a unified view of all property-related activities. As the number of managed properties and active users grew, the platform required an architecture that could scale efficiently while maintaining data consistency, performance, and security.
The Challenge
As adoption increased, the platform began facing several infrastructure limitations. Legacy relational databases struggled to handle high read and write volumes, particularly during peak periods such as rent collection cycles or maintenance request surges. Manual processes for updating property, tenant, and transaction data slowed feature delivery and increased the risk of errors. In addition, monitoring, scaling, and maintaining servers consumed valuable engineering time, limiting the team’s ability to focus on product innovation.
The Solution
KTM One worked closely with the customer to design a modern, AWS-native architecture focused on scalability, security, and operational efficiency. The solution replaced traditional infrastructure with a serverless, high-performance system:
- Centralized Data Management: A single DynamoDB table stores property, tenant, and billing records, simplifying access patterns and ensuring transactional integrity even under heavy usage.
- Serverless Microservices: AWS Lambda functions handle all business operations and are triggered through API Gateway, eliminating manual server management and enabling automatic scaling.
- Secure, Global Access: Amazon API Gateway exposes secure endpoints for web and mobile applications, while static assets and property images are stored in Amazon S3 and delivered globally via CloudFront.
- Monitoring and Observability: Amazon CloudWatch and AWS CloudTrail provide full visibility into logs, metrics, and audit trails, supporting operational insight and security monitoring.
- Automation and Repeatability: Infrastructure is deployed using CloudFormation, ensuring consistent environments and reducing the risk of human error during updates and feature rollouts.
How It Works
When users interact with the platform, requests are routed through API Gateway to the appropriate Lambda functions, which efficiently read from and write to DynamoDB. Static content such as property images is served from S3 and cached through CloudFront for fast delivery. Logs, metrics, and audit events are continuously captured, enabling quick issue detection and maintaining data integrity across the system.
Outcomes & Business Impact
The modernization delivered clear and measurable improvements:
- Sub-10 millisecond latency for accessing property, tenant, and billing data, even during peak traffic
- High availability through Multi-AZ managed services, minimizing downtime
- Significant operational efficiency gains by eliminating manual scaling and server maintenance
- Strong data consistency through DynamoDB transactions, preventing conflicts during concurrent updates
- Cost optimization using on-demand pricing for compute and database operations, reducing idle resource spend
Lessons Learned
Adopting a single-table DynamoDB design was critical in simplifying data access and improving performance at scale. The move to a serverless architecture allowed the engineering team to focus on product development rather than infrastructure management. Comprehensive monitoring through CloudWatch and CloudTrail enabled proactive issue resolution and full auditability. KTM One’s AWS expertise ensured that the solution was secure, scalable, and designed to support long-term growth.
Conclusion
With its new AWS-based architecture, the platform now operates a highly scalable, resilient, and low-latency property management system. The combination of DynamoDB, Lambda, API Gateway, S3, and CloudFront enables efficient handling of growing volumes of properties and tenants. By partnering with KTM One, the customer has established a strong foundation for future expansion, operational excellence, and an improved user experience.
