Overview
Akamai, founded in 1998, operates one of the largest global Content Delivery Networks (CDNs), serving high-traffic websites, media streaming, and enterprise applications. The company delivers content through its Intelligent Edge Platform, which also provides security and edge computing capabilities. Akamai serves major clients like Kuaishou Technology and iQiyi, handling up to 30% of global web traffic. Its solutions cater to industries requiring low-latency content delivery, robust cybersecurity, and scalable cloud services. While historically focused on CDN, Akamai has shifted toward security and cloud computing, with these segments now driving two-thirds of its revenue.
CDNSun, founded in 2012, is a content delivery network provider based in Prague, Czech Republic. It offers services like website acceleration, video streaming, and software delivery through a network of over 50 points of presence (PoPs) worldwide. Its customer base includes businesses seeking cost-effective CDN solutions, particularly small to medium-sized enterprises. CDNSun emphasizes affordability with a pay-as-you-go model and a 15-day free trial. The service supports HTTP/2 and provides free shared SSL on its *.r.worldssl.net domain.
Network & Architecture
Akamai maintains over 325,000 servers across 4,100+ points of presence (PoPs) in more than 135 countries, offering extensive global coverage. Its network leverages advanced routing and peering for low-latency delivery, with strong presence in North America, EMEA, APAC, and a licensed operation in China. Regional limitations include the planned cessation of CDN services in mainland China by June 30, 2026, with transitions to partners like Tencent CDN and Wangsu Science & Technology. Akamai’s architecture supports high-throughput applications like gaming and video streaming, with optimized edge caching and load balancing.
CDNSun operates more than 50 PoPs across five continents, including locations in North America (e.g., Atlanta, Chicago, Dallas), Europe (e.g., Amsterdam, Frankfurt, London), Asia (e.g., Hong Kong, Singapore, Tokyo), South America (e.g., Sao Paulo), and Australia (e.g., Sydney). All edge servers use SSD drives for faster data access and have redundant connectivity to robust internet networks. The network supports global content delivery with a focus on reducing latency for websites and streaming services. Specific routing or peering details are not publicly disclosed, but the provider claims strong performance for global audiences.

Integrations & DevEx
Akamai supports API-first workflows with extensive REST APIs for configuration and management. Its DataStream and Log Delivery Service provide real-time logs and analytics for monitoring. While Terraform support is not natively offered, Akamai’s CLI and SDKs (Python, Java, etc.) enable integration with CI/CD pipelines. Migration tools are available for transitions, such as from Edgio or Lumen Technologies, as seen in recent customer contract acquisitions. Real-time analytics and RUM are supported through Edge Analytics and mPulse.
CDNSun offers an API-first approach for managing CDN services, including access to real-time logs. It provides integration support via a dashboard and API, with 24/7 technical support through email, phone, and live chat. No specific Terraform or CI/CD integrations are documented. The service includes tools for testing performance gains, such as ping tests and downloadable test files (1 MB and 20 MB).
