This is how Temus helped a public sector client reduce case processing time from months to weeks, reducing operational costs by up to 30% and achieving up to 50% in cost savings for investments in hardware and software.
A Singapore statutory board responsible for managing core citizen residential services sought to transform their digital infrastructure on one of their core applications to meet rising citizen expectations and enable future innovation. The organisation faced mounting pressure to improve user experience for both public users and staff, whilst simultaneously reducing operational costs.
The mission-critical application encompassed both front-end citizen portal and back-end processing services. With the existing legacy monolithic architecture, case processing would take as long 6 months and individual staff tasks requiring one or more weeks to complete. The organisation recognised that incremental improvements would no longer suffice.
The organisation focused on addressing three critical objectives:
Temus partnered with them to successfully migrate this citizen service application from a three-tier monolithic on-premises architecture to a cloud-native microservices platform on AWS. We helped established the technical patterns, security frameworks, and organisational confidence for broader digital transformation in the future.
Legacy monolithic applications, whilst functional, can create significant constraints for modern public service delivery. These applications typically bundle all functionality into a single deployable unit, making it difficult to update individual features, scale specific components, or adopt new technologies without extensive regression testing and system-wide deployments.
The importance of application modernisation lies in enabling organisations to respond rapidly to policy changes, scale efficiently during peak demand, and eventually leverage modern capabilities like AI/ML for enhanced citizen services. Cloud-native microservices architectures allow independent scaling, faster deployment cycles, and technology flexibility—critical capabilities for organisations serving millions of citizens with evolving needs. In this case, a modernised cloud-native architecture would help to streamline specific workflows or automate routine processes that would directly impact both staff productivity and citizen satisfaction.
We applied the AWS Migration Framework’s to conduct a comprehensive infrastructure assessment. Working with the organisation, we gathered detailed as-is application and server data, then developed a TCO analysis. We evaluated both lift-and-shift and rearchitecting approaches, ultimately recommending microservices architecture based on analysis of existing and potential future business requirements, like scaling to meet a growth in the volume of citizen transactions on the application, or integration with other platforms and applications.
Adopted Infrastructure-as-Code using Terraform from day one, ensuring consistent, repeatable deployments and enabling rapid environment provisioning. Employed sprint-based execution with structured work breakdown to deliver predictable, low-risk transformation outcomes. The iterative approach enabled continuous learning and adaptation whilst maintaining minimum downtime, with progressive team upskilling through hands-on involvement in each sprint phase. Our security-first foundation maintains Government-grade protection whilst accelerating service delivery, so continuous compliance monitoring could be performed.
Transformed the application from monolithic architecture to cloud-native microservices, fundamentally reshaping how services could be delivered and scaled. Decomposed the front-end portal and back-end processing services into discrete, independently deployable components using Amazon ECS with AWS Fargate for serverless container orchestration. Implemented containerisation with optimised image sizes to improve application start-up time and system responsiveness during peak demand from end users. This architectural shift freed development teams from monolithic constraints, allowing the team the ability to enhance individual services without full system regression testing.
We redesigned backend workflows to make case management more seamless and efficient for staff, then employed cloud-native task automation tools including AWS Lambda for event-driven processing, dramatically improving coordination across case processing steps. The streamlined architecture reduced typical task completion time from one or more weeks to just a few hours, whilst cutting overall case processing time from up to 6 months to 2-4 weeks. These efficiency gains enabled the organisation to achieve its target in time-savings without compromising service quality.
We built a data foundation that would open up opportunities future data analytics initiatives previously constrained by legacy infrastructure. While maintaining data integrity, we seamlessly migrated data to managed database services on AWS Aurora, providing improved performance, availability, and automated management capabilities. Amazon S3 was deployed for scalable object storage, especially as a large volume of images were involved in citizen transactions, thus eliminating future capacity planning concerns.
The cloud-native microservices architecture and automated workflows delivered measurable transformation across operations and costs. By streamlining case processing coordination through event-driven automation and eliminating manual handoffs, we reduced processing time from as long as 6 months to 2-4 weeks. Staff productivity improved significantly, with typical tasks that took one or more weeks now completed in hours, reducing operational costs by 30% without compromising service quality, whilst cloud economics and infrastructure optimisation achieved 50% reduction in hardware and software costs.
Temus can review how your organisation approaches cloud transformation and application modernisation.
