Cloud Engineering, DevOps Automation, Compliance Ready Infrastructure
THE TURNING POINT
As Hoi expanded its presence across major airports and onboarded new partners, the platform’s technology stack needed to match its growing ambitions. The business was evolving rapidly- new routes, new services, and a much larger traveler base, creating the need for a more flexible and resilient cloud setup.
The existing infrastructure had served its early growth phase well but now required modernization to handle higher traffic, faster rollouts, and tighter compliance standards. The goal wasn’t just to upgrade systems but to build a foundation that could keep pace with the brand’s expansion and evolving service portfolio.
That’s where Appinventiv came in. Together with the Hoi team, we set out to design a cloud environment that could scale seamlessly, recover instantly, and meet the rigorous data protection and reliability standards expected from global travel technology platforms.

PCI DSS and SOC2 readiness achieved with secure, encrypted environments.
With a modern AWS backbone, Hoi now delivers faster releases, lower costs, and uninterrupted travel experiences.
Project Challenges
Before writing a single line of code, we looked at how Hoi worked as a business, not just as an app. The idea was to understand where the bottlenecks really came from: slow releases, fragmented setups, and the absence of shared visibility across teams. Our role wasn’t to drop in new tools, but to rebuild confidence in the system from the ground up.
We began with a full infrastructure audit, mapping every dependency and risk area. Then, we designed a phased modernization plan, one that would let Hoi move fast without losing stability. The plan focused on three things that define our delivery approach:
We prioritize getting the base architecture right so scaling becomes effortless later.
Every workflow we automate still keeps a human in control, so teams never lose oversight.
Security & data protection & designed into the system, not patched later.
By the time implementation began, Hoi's team already had a clear view of timelines, outcomes, and risk safeguards. That alignment made the entire transformation smooth and set the stage for the challenges we solved next.
OUR PROCESS
The Hoi project involved solving several infrastructure and operational hurdles that were limiting the platform’s growth.
The platform relied on manual environment creation, which worked well in its early phase but became time-consuming as deployments increased. Maintaining consistency across environments required additional coordination, especially when new features were being introduced rapidly.
All workloads operated from a single availability zone. While this design had supported Hoi's launch, the growing user base demanded higher availability and resilience. Expanding capacity and introducing redundancy were critical steps to ensure continuous service during heavy travel hours.
With more partners and transaction volume, data protection and regulatory alignment became top priorities. The existing structure needed upgrades to meet PCI DSS and SOC 2 requirements, including better encryption, controlled access, and clear audit visibility.
Deployments involved several manual steps and required careful scheduling to avoid interruptions. As feature velocity increased, it became clear that automation would be essential to maintain speed and reliability across releases.
The system generated multiple data streams, but insights were fragmented. Our engineers needed unified monitoring to detect anomalies faster and give the operations team real-time visibility into application health and performance.
As usage grew, resource consumption rose with it. There was an opportunity to make the infrastructure more efficient - aligning costs with actual demand and improving overall resource utilization without affecting performance.
BEYOND OPTIMIZATION
Hoi needed to move away from a setup that was manual, expensive, and difficult to scale. Our goal was to create an automated, secure, and compliance-ready cloud backbone that could handle peak traffic, deliver features faster, and meet strict global standards without driving up costs.
THE IMPACT
Hoi’s transformation wasn’t about fixing one problem but about changing how the platform worked at its core. With automation now driving releases and recovery, the team doesn’t need to pause for maintenance windows or firefight breakdowns. What used to be an unpredictable environment is now stable and transparent, giving Hoi full control over every deployment and update.
The shift also changed the team’s focus. Instead of managing servers, they’re now improving traveller experiences, experimenting with new airport features, and expanding across regions with confidence. Every new partnership can be onboarded faster, every update goes live without risk, and every part of the system runs with built-in accountability.In short, Hoi’s cloud now scales the way the business does - quietly, reliably, and always ready for what’s next.
| Area | Before | After | Business Impact |
|---|---|---|---|
| System Availability | Hosted in a single zone with recurring outages. | Distributed across multiple zones for continuous uptime. | Steady performance during heavy traffic and flight peaks. |
| Deployment Speed | Manual releases that caused interruptions. | Fully automated rollouts with instant version control. | Faster feature launches and stable user experience. |
| Infrastructure Costs | Static servers consuming excess resources. | Auto-adjusting nodes and spot workloads managing real-time demand. | Major drop in monthly spending with higher utilization. |
| API Performance | Delayed responses due to overloaded servers. | Optimized compute and storage delivering quicker data fetches. | Smoother in-app navigation and quicker traveler actions. |
| Compliance | Limited visibility and missing audit structure. | Encrypted data flow with full traceability and access control. | Stronger partner confidence and global audit readiness. |
BEYOND THE NUMBERS
Hoi’s modernization unlocked more than just speed and uptime - it opened new possibilities for the business.

Our team helped Hoi redefine airport experiences through secure, automated, and scalable cloud systems. We can help your travel business reach the same standard of excellence.
Modernization of the Hoi travel companion app depended on several cost variables that were based on project scope, integration complexity, and compliance standards. Airport services app in India require careful consideration of real-time flight tracking systems, automation pipeline development, and AWS travel app architecture design - all factors that influence final budgets.
Project costs like these typically range from $60,000 to $250,000, though actual investment depends on specific technical requirements. A detailed proposal can offer you the most accurate cost projection for your modernization needs.
DevOps implementation for travel applications with automation and compliance requirements usually takes 6–9 months. This timeframe covers Infrastructure as Code setup, pipeline development, observability configuration, and compliant infrastructure rollout.
Timeline extensions occur when projects involve multiple airport connections or complex third-party system integrations that require additional coordination efforts.
Our development methodology uses a structured phase approach:
Working with us involves three straightforward steps:
Airport services platforms frequently experience downtime during peak usage and infrastructure that fails compliance requirements. Hoi faced both these problems before we stepped in.
We addressed these issues by building a multi-AZ AWS travel app architecture, integrating DevOps for travel apps to handle automated releases, and implementing PCI-DSS compliant infrastructure alongside SOC2-ready cloud infrastructure. The result is an airport services app that scales smoothly across features like lounge access, meet and assist, duty-free booking, and real-time flight tracking, reliable during traffic spikes and fully aligned with security standards.
