Running an entire open-source data platform on Elestio

Who is Rezcomm

Rezcomm is a plug-and-play ecommerce marketplace platform built for airports, parking operators, venues and travel hubs. It gives them a single, scalable marketplace spanning travel, reservations, ecommerce, venue, customer, marketing, business and AI modules, the commercial engine behind how millions of travelers book parking, retail and services.

Rezcomm is “Uniquely Independent”: rather than reselling someone else's stack, it builds and refines its own technology continuously. It operates from dual headquarters in the UK (Exeter Science Park) and the USA (Wilmington, Delaware), and its platform is GDPR and PCI compliant.

The challenge: production-ready open source is expensive

Rezcomm's stack is open-source by choice, and the tools are best-in-class. The problem was never the software, it was everything around it. Running open source in production yourself means provisioning infrastructure, hardening security, configuring backups, and wiring up monitoring, for every service. Rezcomm's most valuable engineers were spending their time getting open-source software to a production-ready standard instead of building the product. Every new tool came with a hidden DevOps tax.

The turning point: one platform, one workflow

Rezcomm moved to Elestio and collapsed that entire problem into a single platform. Every service now follows the same deployment workflow: one platform, one way to deploy, one team to talk to. Time-to-production went from a project to a coffee break. Standing up a new open-source service is about five minutes, the same secured, backed-up, monitored, production-grade outcome, without diverting engineers from mission-critical work.

What Rezcomm runs on Elestio

This is not a single-app deployment. True to its “Built to Scale” philosophy, Rezcomm runs a broad open-source platform on Elestio, spanning data, analytics, identity, automation, messaging, and delivery.

The game changer: experimentation without risk

Spinning up a service is fast, isolated, and priced so a small test instance carries no risk of a surprise bill. The team can evaluate new open-source software the moment they are curious, a new AI tool, a new BI engine, a new database, as a five-minute experiment instead of a budgeted project. The pricing model made expanding into new open-source tooling something Rezcomm can do continuously, with no billing-overage risk and no impact on production.

Where it leaves them

Rezcomm gets the freedom and customizability of open source, without the operational weight of running it. One platform, one deployment workflow, and a pricing model that rewards curiosity. The infrastructure takes care of itself, and Rezcomm's engineers stay focused on building the product their customers actually pay for.
