How RentalReady eliminated a DevOps bottleneck and increased deployment capacity 17x

RentalReady (by GuestReady) is the leading European Property Management System (PMS) for short-term rentals. In 2025, during a phase of hyper-growth, the engineering team faced a classic scaling paradox: the more they grew, the slower they moved.

By partnering with Qovery to move from a rigid AWS ECS setup to a self-service Amazon EKS platform, RentalReady didn't just cut costs; they multiplied their deployment capacity by 17.

The Challenge: The "Single Point of Failure" Bottleneck

Following the migration from Heroku to AWS ECS, RentalReady found themselves dealing with an increasingly rigid infrastructure. While the system was technically functional, it couldn't keep pace with the needs of a fast-growing engineering team, leading to three critical issues:

• The DevOps Centralization: With 16 developers now on board, RentalReady identified an opportunity to modernize their deployment pipeline. By moving away from a single point of operational management, the team unlocked greater autonomy for its engineers and freed up senior leadership to focus exclusively on core architectural innovation.
• The ECS "Ceiling": The team hit technical limitations with ECS Fargate, particularly regarding complex orchestration and the inability to use cloud-native tools like KEDA for advanced autoscaling.
• Scaling Costs: As the business grew, the lack of granular control over compute resources led to inefficient cloud spend that didn't align with their actual usage.

The Solution: Abstraction without Limitation

RentalReady chose to migrate to Amazon EKS, but they knew that managing Kubernetes directly would only increase the burden on DevOps. They implemented Qovery as the Kubernetes management platform to act as the "easy button" for their new infrastructure.

Key Technical Pillars:

• KEDA Integration: By moving to EKS via Qovery, the team was able to implement KEDA (Kubernetes Event-driven Autoscaling). This allowed them to scale based on specific business logic and timings rather than just waiting for CPU spikes.
• Self-Service Onboarding: Deployment power was handed to the developers. Using Qovery’s interface, the onboarding for the 16-person dev team was completed in less than one week.
• "Private-First" Security: The migration was used to overhaul the VPC architecture, enforcing mandatory deployment on private subnets and moving to a cleaner, CNAME-based DNS setup for better ownership.

The Migration Process: 6 Weeks to Production

Speed was balanced with architectural stability. The migration focused on a "Private-First" networking overhaul.

• Weeks 1 & 2: Staging environment set up on Qovery (EKS cluster) and work on architecture diagrams for DNS setup.
• Weeks 3 & 4: Financial and technical validation, during which we validated the 30% cost-optimization proposition.
• Weeks 5 & 6: Production workloads migrated and the full engineering team onboarding.

Qovery worked closely with the team to assess the technical changes in their architecture, not only from ECS to EKS. 

Throughout the migration, Qovery provided hands-on technical support and remained available afterward via Slack. Infrastructure migrations don’t end at deployment; they require reassurance and partnership beyond go-live.

“The migration to Qovery was very fast, and the ROI for our teams was immediate.” François Lavie, CTO, RentalReady

The Results: 17x Deployment Capacity

The ROI was visible within the first month of the six-week migration.

1. Developer Autonomy (The Core Win)

The responsibility for deployments shifted from 1 person to 17 people. Developers now manage their own environments and services independently.

• Zero Friction: New developers are productive in days, not weeks, thanks to the abstracted environment management.
• Operational Autonomy: Engineering teams now manage their own service scheduling and environment variables independently. This has eliminated cross-team dependencies and "sync conversations," allowing the company to scale its service offerings without increasing team collaboration overhead.

2. Significant Cost Optimization

By moving to EKS and utilizing smarter scaling tools, RentalReady achieved:

• 30% reduction in EC2 compute spend through granular resource scheduling.
• 20% reduction in storage costs by migrating from GP2 to GP3 volumes.
• 10% additional savings via NAT Gateway optimization and KEDA-driven autoscaling.

3. Architectural Excellence

• Cloud-Native Ecosystem: The team now has native access to the full Kubernetes ecosystem (Helm, Ingress Controllers) without the operational overhead of managing them manually.
• Resilience at Scale: As RentalReady continues to dominate the European PMS market, their infrastructure now scales dynamically with business growth, not headcount.

4. High-Performance Elasticity: 

• Elastic Performance at Neutral Cost: By implementing Karpenter and Qovery, the cluster now scales dynamically between 60 and 90 nodes. This provides significantly higher performance and "burst" capacity without increasing the baseline budget.
• Zero-Downtime Reliability: The integration of advanced lifecycle jobs ensures that deployments are now completely transparent. The team has achieved zero downtime, with the system intelligently managing node transitions and service health.

Conclusion: From Infrastructure Debt to Market Leadership

The transition from AWS ECS to a Qovery-managed EKS environment marked a turning point for RentalReady’s engineering culture. By stripping away custom scripts and manual task orchestration, the team shifted their focus from infrastructure maintenance to product innovation.

As the first European "Scaling PMS," RentalReady is currently maintaining 100% year-over-year growth. Their infrastructure now operates on a platform that scales dynamically with their business growth. For RentalReady, the ROI was clear: 30% lower compute bills, a 17x increase in deployment capacity, and an engineering team that finally has the autonomy to build at the speed of their ideas.
