Customer Overview
The customer is a T`hailand-based provider specializing in employee benefits management for organizations operating under self-insured models. The business delivers digital platforms that support benefits administration, customer servicing, and licensed insurance personnel training accredited by Thailand’s Office of Insurance Commission (OIC).
Business Challenge
The customer’s core production workloads—including customer portals, internal operations systems, training platforms, and policy-related services—were originally hosted in the AWS Asia Pacific (Singapore) Region.
As the majority of users, customers, and licensed insurance personnel are based in Thailand, the organization identified increasing latency for business-critical workflows that directly impacted customer experience. Cross-border network paths to Singapore introduced avoidable delays in customer self-service, benefits processing, and staff training systems.
At the same time, the customer saw an opportunity to optimize infrastructure costs by migrating workloads closer to its primary user base. With the AWS Asia Pacific (Thailand) Region available, the organization aimed to reduce application latency, simplify regional architecture, lower inter-region network dependency, and improve overall cost efficiency while maintaining business continuity. The customer required a structured migration approach with minimal downtime, secure landing zone governance, and measurable performance and cost improvements.
What Was Built and How
SiS Distribution designed and delivered a region-to-region migration from AWS Singapore to the AWS Asia Pacific (Thailand) Region using a phased migration framework aligned with AWS best practices.
The engagement started with workload discovery, dependency mapping, and migration wave planning across web applications, APIs, databases, training systems, and customer-facing portals. A new AWS multi-account landing zone was deployed in the Thailand Region using AWS Organizations, separating production, non-production, shared services, logging, and security domains to strengthen governance and operational control.
The network architecture was redesigned using a hub-and-spoke VPC model connected by AWS Transit Gateway, enabling optimized domestic traffic routing for users, branch offices, and insurance agents across Thailand. This significantly shortened the network path between users and applications.
Application workloads were migrated using infrastructure-as-code redeployment patterns for application services, while databases and supporting data layers were transitioned through controlled backup, restore, and replication workflows to ensure business continuity. The migration was executed in phased waves to reduce business risk:
customer portal and training services
internal employee benefits operations
policy and claims platforms
Operational visibility and governance were standardized using Amazon CloudWatch, AWS CloudTrail, AWS Config, and AWS Security Hub.
This migration established a scalable Thailand-based cloud foundation that improves local performance while maintaining enterprise-grade security, governance, and operational resilience.
