Ozsnow Cloud Migration
A full-stack modernisation of legacy Java infrastructure — containerised, migrated to AWS, and equipped with enterprise-grade CI/CD and security for a leading ski travel company.
Project Overview
Ozsnow is an Australian ski and snowboard travel company offering curated snow trips, lift passes, and accommodation packages. Despite strong market positioning, their technology stack was holding them back — outdated Java applications, no CI/CD pipeline, and infrastructure that couldn't scale to meet seasonal demand spikes.
Kurrajong Studio was brought in to modernise the entire stack: converting legacy applications to Spring Boot, containerising everything with Docker, and migrating to a robust, secure AWS cloud environment with automated deployment pipelines.
The Challenge
- Outdated Java applications with no modern framework structure, making updates slow and risky.
- Thread-unsafe DBCP connection pooling causing instability under load — critical during peak booking seasons.
- No containerisation — deployments were manual, inconsistent, and prone to environment-specific bugs.
- No CI/CD pipeline — code changes required manual deployment steps, slowing the development cycle.
- No cloud infrastructure — running on unmanaged servers with no backups, monitoring, or security hardening.
- Security gaps: no WAF, no VPN, no formalised access control for sensitive customer data.
The Solution
The migration was executed in four coordinated phases, ensuring continuity of service throughout.
Application Modernisation
Converted all Java applications to Spring Boot with Gradle. Replaced thread-unsafe DBCP with HikariCP — the fastest JDBC connection pool for Java. Refactored data sources as singleton services to eliminate concurrency issues.
Containerisation with Docker
Created Dockerfiles for every application, enabling consistent builds across all environments. Orchestrated deployments with Docker Compose and implemented Watchtower for automatic container updates.
CI/CD Pipeline with GitHub Actions
Automated the full build-test-deploy pipeline. Code merged to main triggers automated testing, Docker image builds pushed to Amazon ECR, and zero-touch deployments to production.
AWS Cloud Infrastructure
Provisioned EC2 instances, automated RDS backups, deployed a Web Application Firewall, configured a VPN for secure internal access, set up Nginx as reverse proxy, and configured DNS through cPanel.
The Outcome
Automated CI/CD reduced deployment cycles from manual hours to minutes.
WAF, VPN, and access controls protect customer and booking data.
AWS infrastructure scales to handle peak snow season traffic.
