Harbers Group is a proud sponsor of the Bloemencorso Lichtenvoorde, one of the largest flower parades in the world. Every year, eighteen towering parade floats, adorned with thousands of dahlias and full of movement, music, and technology, make their way through the streets of Lichtenvoorde.
Behind the scenes, the parade is no longer just about the impressive number of flowers, but also about theater, innovation, and high-tech solutions such as hydraulics. It’s a breathtaking spectacle for the audience.
For the 2025 edition, Harbers Group developed a completely new voting site that allowed the public to easily vote for their favorite parade floats. The site was fully hosted in Harbers Group’s own Dutch data center and offered a secure, fast, and user-friendly experience for both visitors and the organization.
With the voting site, the public could select three favorites, leave their contact details for a prize draw, and vote in a separate CorsoKIDS category. Voting was only possible within a predetermined time slot. Immediately after the event, the jury received real-time insight into the results.
The solution consists of two applications: an API built with C# and .NET 9, and a modern Single Page Application (SPA) developed in Vue.js 3. The frontend communicates with the API for authentication, validation, and vote storage. For the management portal, Microsoft Entra ID was chosen, allowing administrators to log in securely and reliably with their existing Microsoft accounts.
Security was paramount. Device fingerprinting prevents and/or detects duplicate votes, geo-filtering restricts voting to permitted countries, and rate limiting protects against DDoS attacks. The site is hosted from our own geographically separated private cloud in the Netherlands, with load-sharing across multiple web servers to ensure optimal performance during peak times. During voting, a support team continuously monitored the site and immediately followed up on any suspicious activity.
The voting site was successfully deployed during the parade. The audience award went to VedutNogal with “Leedvermaak.” Harbers Group congratulates VedutNogal on this achievement. For Harbers Group, this was a great project where development, private hosting, and security came together in an innovative solution for a unique event.
