Legacy reservation software replaced
with a modern, mobile-friendly AWS platform
Case study – Travel & Hospitality
GVM Sion – one of Switzerland's oldest flight schools – was running its whole operation on ageing aircraft-reservation software: hard to maintain, no mobile, and tied to a single club. 56k.Cloud rebuilt it as Aviator, a serverless platform on AWS that GVM Sion owns going forward – and now rents as a service to other flight schools too.
GVM Sion's reservation software had aged out. It wasn't mobile-friendly, it was slow to maintain, and as students and members grew it couldn't keep up with what a modern flight school needs: pilots pulling up-to-date aircraft documentation and checklists, instructors tracking student progress, and the club following flight hours and maintenance issues. Everything the system didn't cover fell back to manual admin – time taken away from flying.
The architecture
Business logic runs on AWS Lambda, so the backend scales with demand instead of sitting on servers someone has to keep alive. Amazon API Gateway fronts the API and authenticates requests with JWT tokens, Amazon DynamoDB is the primary database, and Amazon Cognito handles user identity and access. The whole environment is provisioned with Infrastructure-as-Code, and every application and infrastructure change is tested and deployed through CI/CD pipelines. On top sits a modern Next.js frontend – an interactive aircraft reservation calendar and analytics dashboards the school uses to watch aircraft activity. And because it's multi-tenant, a second, third, and further flight school can run on the same platform.
The outcome
with a modern, mobile-friendly AWS platform
pilots, instructors and admins working in one system – reservations, documentation, student progress, flight analytics
that scales with demand and only bills for what it uses
on managed infrastructure the school doesn't have to run
to other flight schools – a maintainable foundation GVM Sion owns going forward

It runs in production today – built with GVM Sion, owned by them and resold to other flight schools, and operated by us for as long as they want.
