Technology Stack Definition

Overview

Laya Healthcare engaged SevTech to deliver a proof of concept (PoC) for a new technology stack and application architecture.

SevTech worked closely with Laya’s IT development team to evaluate technologies, define a scalable architecture, and implement a vertical slice of the application. The PoC validated the feasibility of the new stack while informing a phased migration plan for full-scale adoption.

Challenge

Laya Healthcare sought to modernise its technology stack while ensuring minimal disruption to operations.

 A key challenge was selecting the right stack and designing an application architecture that could support long-term scalability. Additionally, the PoC needed to demonstrate how the new stack would integrate with existing systems, allowing a dual-run transition from legacy to modern technology with minimal risk.

Results

• Validated Technology Stack: The PoC demonstrated the feasibility of the selected stack.

• Proven Architecture Design: Ensured scalability, security, and performance.

• Risk-Managed Migration: A clear plan for a smooth transition from legacy to modern systems.

• Confidence in Implementation: Real-world testing confirmed the stack’s viability.

• Stronger IT Collaboration: Strengthened alignment between SevTech and Laya’s IT development team.

Solution

SevTech collaborated with Laya’s IT development team to:

Select the Technology Stack – Evaluated and chose a modern, scalable stack.

• Design the Application Architecture – Defined a flexible, future-proof architecture.

• Develop a Proof of Concept – Built an end-to-end vertical slice to validate performance, integration, and scalability.

• Plan the Migration Approach – Outlined a phased strategy allowing old and new systems to run in parallel during the transition.
