Cloud CDN

Accelerate Content Delivery. Optimize Performance. Bring Digital Experiences Closer to Users.

LTA Digital provides Cloud CDN solutions from leading global infrastructure providers — Alibaba Cloud, BytePlus, and CDNetworks.

Introduction

Cloud CDN is a content delivery solution that utilizes a global network of Points of Presence (PoPs) to deliver content to users from the nearest available location.

Instead of routing every request back to the origin server, CDN caches copies of content at distributed PoPs and delivers them directly to users. This helps businesses reduce latency, minimize origin server load, optimize bandwidth utilization, and improve user experience.

As a reseller and implementation partner of multiple leading CDN infrastructure providers, LTA Digital helps businesses select the most suitable CDN solution based on their user demographics, geographic coverage, and operational requirements — without being restricted to a single provider ecosystem.

How Does CDN Work?

Bringing Content Closer to Users

When users access websites, videos, images, or other digital resources, the CDN system identifies the most appropriate PoP based on their location and network conditions.

Step 1 User Sends a Request — The user accesses a website or digital resource through a CDN-enabled domain.
Step 2 CDN Selects the Optimal PoP — The routing system selects the most suitable delivery point based on the user's location and network conditions.
Step 3 Cache Lookup — If the requested content is already cached at the PoP, it is delivered directly to the user.
Step 4 Origin Server Retrieval — If the content is not cached or has expired, the PoP retrieves it from the origin server.
Step 5 Content Caching and Delivery — The content is delivered to the user and cached at the PoP to serve subsequent requests.

Result: Fewer requests to the origin server, reduced infrastructure load, and faster content delivery.

Global CDN Network

LTA Digital provides CDN solutions from three leading infrastructure providers, each offering distinct strengths in geographic coverage and use cases. This allows businesses to select the most suitable solution based on their specific requirements.

Architecture

From Users to Origin — Through an Intelligent Edge Layer
01. Routing System Monitors PoP availability and route quality in real time.
02. Route Quality System theo dõi tình trạng PoP và chất lượng tuyến trong thời gian thực
03. Caching System Checks content availability at the PoP. Cache hits are served directly, while cache misses trigger retrieval from the origin server before the content is cached.
04. Support & Monitoring Provides system monitoring, data analytics, and configuration management.
General Flow: User → DNS/Routing → Edge PoP → Cache → Origin Server
