Overview
Azion Technologies offers a global edge computing platform and CDN, focusing on performance, security, and scalability for digital applications. Founded in 2011, the company serves industries like e-commerce, finance, and media with solutions for web acceleration, security, and serverless computing. Customers include enterprises and developers building mission-critical applications such as AI, IoT, and real-time streaming. The platform emphasizes programmability and automation, integrating with modern DevOps workflows. Azion operates a global network with a strong presence in Latin America.
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
Azion operates over 100 points of presence (POPs) across North America, Latin America, Europe, Asia, Africa, and Oceania, with notable strength in Latin America, particularly Brazil. Its edge network leverages intelligent routing and peering with major ISPs to optimize latency and reliability. The platform uses a distributed architecture to support edge computing and content delivery, with capabilities like Edge Functions for serverless processing. Limitations include less extensive coverage in certain APAC and Middle Eastern regions compared to larger competitors like Cloudflare or Akamai.
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.
