Client Context
A major government ministry in Singapore managed national-scale educational and administrative platforms.
Business Challenge
- Rapidly growing instance count of 100+ lacked standardized, repeatable provisioning.
- Complex networking requirements needed secure tunnels and segmented VPCs.
- Manual changes to API Gateways and Lambda functions caused environment inconsistency.
Helius Approach
Terraform was implemented for VPCs, subnets, route tables, and API Gateways.
100+ EC2 instances were provisioned and configured across diverse OS platforms.
11+ VPN tunnels were facilitated and managed for secure cross-departmental access.
Business Outcome
- Terraform integration reduced environment spin-up time from days to hours.
- 11+ VPN tunnels were managed with 200+ CloudWatch alarms for connectivity health.
- VPC and subnet isolation was enforced via code, reducing manual configuration errors.
Capabilities and Technologies
- Skill Sets: Platform Automation (IaC), Large-Scale Cloud Provisioning, Hybrid Cloud Networking (VPN), Standardized VPC Architecture, Serverless Component Configuration
- Technologies: AWS / Terraform, AWS Lambda & API Gateway, Amazon S3 & DynamoDB, Site-to-Site VPN Tunnels, AWS ElasticCache
