A Content Delivery Network is a network of distributed servers that delivers digital content to users as quickly and reliably as possible. Content includes not only text and images, but also videos, scripts, styles, documents, and archives. In other words, CDN is a technology for accelerating website loading, especially under high traffic loads and with a geographically distributed audience.

Modern users are not willing to wait. If a site takes longer than 3 seconds to load — 40% of users will leave. A slow resource negatively impacts sales, reputation, and SEO. CDN networks solve these problems.

A CDN integrates into IT infrastructure as an external service and addresses the following challenges:

• Reduces website loading time;
• Decreases hosting load;
• Increases fault tolerance;
• Ensures stable operation during traffic spikes;
• Provides DDoS attack protection.

How a CDN Server Works

Typically, a website is hosted on a single server (whether in the same country or abroad). With each request, users — even those from other regions — pull content from this server. This slows down loading, especially when traffic comes from mobile devices or from another country.

A CDN for websites solves this problem differently:

• Website content (images, videos, styles, scripts) is cached on CDN servers worldwide.
• When a user makes a request, data is delivered from the nearest CDN node, not from the origin server.
• Page loading speed increases significantly.

What Business Problems Does a CDN Solve?

Accelerated Website Performance

The faster the site — the higher the conversion rate, the longer users stay on the page, and the better the search engine rankings.

Hosting Cost Optimization

A CDN service offloads the origin server, reduces load, and allows for savings on scaling infrastructure.

High Traffic Support

Promotions, marketing campaigns, media publications — a CDN handles traffic spikes without downtime.

Security and Fault Tolerance

CDN providers offer malicious traffic filtering, DDoS protection, and automatic failover between servers.

Convenient Media Delivery

Video, graphics, large files — a CDN makes them accessible without delays or buffering.

Where CDN Is Applied

Possible use cases for the technology:

• E-commerce: faster loading of product pages, filters, and images.
• Media and blogs: quick loading of news, photos, and videos.
• Services and SaaS: stability with a large number of concurrent users.
• Financial sector: enhanced security and interface speed.
• Corporate websites: availability and resilience of brand resources.

Local Providers and Regional Solutions

Given the growing demands for data sovereignty and response speed in Russia and Uzbekistan, local CDN providers are increasingly being chosen. Such solutions comply with legal requirements, operate through data centers in Uzbekistan, and ensure high performance and SLAs.

Popular CDN services are part of the ecosystem of major telecom operators and data centers. They include CDN storage, analytics, cache control, APIs, and support for protocols such as HTTP/2, TLS 1.3, and others.

How to Connect a CDN to Your Website

Connection algorithm:

1. Select a CDN provider based on geography, traffic volume, content format, and security requirements.
2. Configure the delivery zone (domain, caching rules, TTL).
3. Integrate with the site: via DNS record changes or CMS integration.
4. Conduct testing — measure speed, response time, and stability.

CDN technology is becoming a standard for companies operating online. Whether you sell products, provide services, or publish content, a content delivery network helps make your business faster, more resilient, and more reliable.
