Customer Challenge
The client required a robust and scalable cloud platform to support the continued operation and growth of its impact measurement and reporting solution—a web-based system used to capture, process, and analyse SME performance data across multiple programmes and cohorts.
While the platform was already operational, increased adoption and expanding programme scope placed growing pressure on the underlying infrastructure. The system needed to reliably support structured data capture and reporting workflows while maintaining high availability, strong security controls, and operational stability.
Key challenges included ensuring consistent availability as platform usage increased, supporting event-driven data capture and processing workflows, protecting sensitive SME performance data, establishing operational visibility and monitoring, and providing a scalable foundation for future feature expansion. Without a stable and scalable cloud environment, the platform risked performance bottlenecks, reduced resilience, and increased operational overhead as adoption continued to grow.
Partner Solution
Tati Software partnered with the client to design and implement a secure, scalable AWS-based platform that stabilised the existing solution while enabling future growth.
The solution was built using cloud-native and event-driven design principles, leveraging managed AWS services to improve reliability, scalability, and operational visibility while reducing infrastructure management effort. The architecture supports asynchronous processing, modular service components, and elastic scaling to handle peak reporting cycles without performance degradation.
By introducing a resilient cloud foundation with built-in monitoring, automated scaling, and security controls, the solution established a sustainable SaaS operating model aligned with the client’s long-term platform roadmap.
Primary AWS Services Used in the Solution and How They Were Delivered
The platform was implemented using AWS Well-Architected principles, with a focus on security, reliability, and operational excellence.
The following AWS services were used:
- Amazon ECS on AWS Fargate: Runs containerised application services with automatic scaling and high availability
- Amazon RDS for PostgreSQL: Stores structured SME performance data with encryption, backups, and high availability
- Amazon SQS: Enables asynchronous, event-driven data processing and prevents bottlenecks during peak usage
- AWS Lambda: Supports lightweight, event-driven processing tasks such as data validation and notifications
- Amazon S3: Durable storage for historical data, exports, and audit artefacts
- Amazon CloudWatch: Centralised logging, monitoring, and alerting for operational visibility
- Amazon VPC: Network isolation and secure service-to-service communication
Partner Support Services (Pre and Post Implementation)
Tati Software provided end-to-end support across the solution lifecycle. Pre-implementation, Tati Software designed the cloud architecture and deployment model to support both current operational demands and anticipated growth.
During implementation, Tati delivered the AWS infrastructure, established CI/CD pipelines, configured monitoring and alerting, and optimised the platform for resilience and scalability. Post-implementation, Tati Software continues to provide managed operational support, including performance optimisation, monitoring, and ongoing platform enhancements to support evolving business requirements.
Results and Benefits
The AWS-enabled platform delivered measurable improvements aligned with the client’s operational and strategic objectives.
Key outcomes include:
- Achieved greater than 99.9% platform availability, ensuring consistent access for programme stakeholders
- Supported up to three times higher concurrent data submissions during reporting cycles without performance degradation
- Reduced infrastructure and operational management effort by approximately 40% through the use of managed AWS services
- Strengthened data security through encryption, network isolation, and controlled access
- Enabled 30–50% faster delivery of new features due to a modular, cloud-native architecture
The solution established a stable SaaS foundation that allows the client to scale its impact measurement platform confidently while maintaining data integrity, transparency, and stakeholder trust.
