How Did We Manage Serving Terabytes of Data to Our Customers Worldwide
Building a high-performance 3D web application takes more than an advanced frontend. This article explains how backend technologies such as CDN and caching improve speed, scalability, availability and SEO. Using Vinode as an example, we show why efficient content delivery is essential to a smooth user experience in real estate 3D web applications.
Introduction
Developing a 3d web app is a complex process. By describing not only the platform's visible features - the frontend - but also what happens "behind the curtain" - the backend - we aim to make our solutions easy to understand.
This article covers how we achieve a fast web experience, focusing on caching and CDN.
At Prographers, we provide 3D web application solutions that let companies configure their products with high-quality content.
Vinode, our technology for the real estate business, is a complete marketing solution that combines state-of-the-art 3D visualization of properties and their environment with web platform operations. Customers configure a house with basic 3D in a web browser and render each view, but many technical elements have to be refined for that journey to run smoothly.
Web browser requests
When a user types a domain name - say "prographers.com" - the browser issues an HTTP request that goes to the DNS Server (Domain Name System), which finds the correct IP address for that site. The browser then uses this address to communicate with an origin server or CDN edge server to fetch the information it needs.
What is a CDN server and how does it work?
A CDN server, also known as a proxy server, is a distributed infrastructure of nodes - data centers and servers - that work together to deliver requested internet content to users based on their geographical location. This targeting is called CDN routing: directing a user's query to the most appropriate edge server.
For example, a request from someone in the US doesn't have to travel to our server in Europe; it reaches a nearby intermediary instead, which speeds up the process. That edge server occasionally checks with our European server whether the resource still exists, but the delay barely matters because the CDN usually already has what it needs, preventing latency. This gives the site better performance. Intermediation through a CDN also proved cost-effective, scalable, and robust, streamlining the client engagement process.
Caching / cache
Caching is the process of storing and accessing data from a cache, and it's a pivotal component of CDN architecture. So what is a cache? It's a software or hardware component dedicated to storing data so that future requests for the same data can be served faster - in effect, an efficient memory. There are different caching methods; ours is CDN caching, one of the most crucial parts of the backend of our applications.
Benefits of Caching
These benefits show the full scale of the method.
The advantages of CDN caching include:
IMPROVED PERFORMANCE
This mainly means offloading static content delivery from the source server, freeing resources for dynamic content generation and decreasing the load on the server.
REDUCED LATENCY
By delivering content from locally distributed edge servers, CDNs significantly shorten the time it takes for content to reach the user, leading to much faster page load times.
SCALABILITY
A CDN handles sudden traffic spikes and high volumes of simultaneous requests flawlessly, making it easy to scale our web application regardless of traffic. As a website grows and its traffic increases, the CDN scales rapidly to meet demand, so the site can serve more users without affecting speed or experience.
SECURITY
We will devote a separate blog post to this part, but our CDN also provides valuable features such as protection from DDoS (distributed denial-of-service) attacks, SSL/TLS termination at the edge, and Web Application Firewalls (WAF).
BETTER AVAILABILITY
Thanks to the different locations of servers and their error resilience, content delivery stays continuous. When one server becomes unavailable for any reason, requests are automatically redirected to another.
COST SAVING
Correctly configuring a CDN reduces the cost of transferring data. By optimizing bandwidth usage and lowering server load, a CDN cuts both bandwidth expenses and overall infrastructure costs.
CDN impact on SEO
Page load time has a significant impact on SEO - an essential part of any website.
Although Google maintains that CDNs don't directly affect a site's SEO, faster access is crucial: the longer a page takes to load, the more users abandon it, and that hurts your page's SEO.
Why caching is so important
Without caching, the best performance simply isn't possible.
As developers, we watch this factor closely, because deploying the leanest versions of our apps - and never leaving customers staring at a loading message - matters. More and more companies now use caching, so it pays to choose a method that works better than the rest to stand out.
Conclusions
CDNs are far more than a server network. In this article, we've covered why caching matters and why a CDN is the right tool for it.

FAQ
Why is caching crucial for 3D web applications? Caching allows frequently requested content to be delivered faster, reducing server load and improving overall application performance and user experience.
What role does a CDN play in website performance? A CDN distributes content across multiple geographically located servers, ensuring that users receive data from the nearest edge server, which minimizes latency and speeds up page loading.
Does using a CDN improve SEO? While CDNs do not directly influence SEO rankings, faster page load times reduce bounce rates and improve user experience, which indirectly supports better SEO performance.
How does CDN caching handle traffic spikes? CDNs are designed to manage sudden increases in traffic by distributing requests across multiple servers, ensuring stable performance even during peak usage.
Is caching only important for large websites? No. Caching benefits websites of all sizes by improving speed, reliability and scalability, regardless of traffic volume.
Can CDN solutions enhance website security? Yes. Many CDN providers offer additional security features such as DDoS protection, SSL/TLS termination and web application firewalls, helping protect applications from threats.
Core Web Vitals for property sites: how to actually measure a 3D tour's impact
One green desktop Lighthouse run on the tour page is not proof the tour is fine. Lab tools and field data answer different questions, and the metric a 3D tour is most likely to fail — INP — is one Lighthouse cannot score at all. Here is how to read the field data at the 75th percentile, and why a freshly launched development page shows "No Field Data" for weeks.
The asset budget is what breaks 3D at 500 units, not your polygon count
Grinding on the model has a hard ceiling at masterplan scale. LOD tiers, a texture memory budget, draw-call limits, and streaming order decide whether a 528-unit scene loads on a buyer's phone. Here is what that budget looks like at 25 buildings, and why no amount of tuning upgrades the device in their hand.
The real cost of streaming 3D per viewer: a worked GPU-and-CDN cost study
Two ways to serve an interactive 3D tour, two cost curves that point in opposite directions. This is the arithmetic worked out at dated public rates: what 100, 1,000 and 10,000 concurrent viewers actually cost on a GPU fleet versus a CDN, and the two numbers that decide where the lines cross.
