CDN Reviews

Zenlayer is a company that many people recognize first from its bare metal, global network or acceleration products, but CDN is not the most famous line. However, from the perspective of product structure, its CDN is more like an extension of its global network capability than a traditional CDN that sells cached traffic alone. Zenlayer's advantage lies in its own cross-regional backbone network and a large number of overseas nodes, especially in Southeast Asia, Latin America and the Middle East, where the network coverage is relatively dense. Zenlayer's advantage lies in its cross-regional backbone network and a large number of overseas nodes. This also determines that its CDN is more suitable for cross-border and overseas access optimization, rather than simply pursuing the low domestic limit ......

IO River is an emerging CDN and network acceleration service provider that has gradually gained attention within the tech community in recent years. Its overall positioning does not follow the “massive and comprehensive” approach of international cloud vendors, but rather leans toward providing controllable, transparent, and relatively flexible content distribution and foundational security capabilities for small and medium-sized global businesses. Judging from its official website and console design, IO River clearly prioritizes CDN, edge acceleration, and core security services themselves, rather than attempting to build a complete cloud ecosystem. In terms of regional coverage, IO River's node distribution spans North America, Europe, and parts of...

I. Why Choose VNG Cloud CDN for Evaluation VNG Cloud possesses a significant user base within the Vietnamese market and the Asia-Pacific region's cloud services landscape. Its CDN service (vCDN) is positioned as a solution offering high-availability acceleration + DDoS protection, with distinctive features in localized access and network link optimization. Unlike purely overseas CDNs, it functions more as an option tailored for “regional acceleration and optimized access for domestic + Southeast Asian users.” II. Test Environment and Real-world Access Scenarios Project Description Testing Party Our Network Security and Performance Team Business Type Static...

I. Why CDN07 Was Chosen for This Review If you're frequently involved in overseas business, cross-border projects, or more niche technical scenarios, you've likely heard of CDN07—yet genuine user-centric reviews remain scarce. My choice of CDN07 as the service provider is straightforward: its actual performance in the Asia-Pacific region is more stable than many mainstream CDNs, and it offers significant “freedom” in terms of service restrictions, payment methods, and privacy policies. This isn't a CDN for novice webmasters; it's for those who know exactly what they need. II. Test Environment and Actual Deployment Conditions...

I. Why Choose Bunny.net for CDN Evaluation If you've been following the CDN scene for a while, you'll notice Bunny.net often gets labeled as “too cheap to be a legitimate CDN.” This time, choosing Bunny.net isn't about proving whether it can compete head-to-head with Cloudflare or Fastly. Instead, we aim to answer a more practical question: Can such low pricing actually work for real-world business use? Especially for small and medium-sized sites, tool-based platforms, and content-focused websites, Bunny.net's pricing...

I. Why Azure CDN Must Be Tested Independently In real-world projects, Azure CDN rarely appears as a “standalone CDN solution.” It is more often integrated within the Azure ecosystem. This Azure CDN evaluation isn't about comparing its speed against Cloudflare. Instead, it addresses a more practical question: When your business is already running on Azure, is it necessary to add a third-party CDN? This review fundamentally answers an enterprise architecture decision. II. Test Environment and Access Background...

I. Why Gcore Was Chosen for This CDN Evaluation This evaluation of Gcore was not merely a matter of “it being Gcore's turn.” Rather, it stems from a very real issue encountered across multiple overseas projects: suboptimal access stability at certain European and Eastern European nodes, coupled with mainstream CDNs in this region offering poor price-to-performance ratios. Gcore's public materials emphasize its node coverage and network quality across Europe, Eastern Europe, and the CIS region—precisely the motivation for this evaluation. II. Test Environment and Baseline Information Project Description Testing Party Independent Network...

Choosing CacheFly for testing wasn't because it's “super popular”—quite the opposite. It's precisely because its presence in China's tech community is minimal, yet it consistently appears in streaming media, game downloads, and enterprise distribution scenarios. The purpose of this test is straightforward: When mainstream CDNs (Cloudflare/CloudFront) show instability in certain regions, can CacheFly still serve as an “engineering fallback option”? I. Actual Deployment Context and Test Environment CacheFly's integration process is straightforward, though notably...

When users access your website from different cities or countries, loading speeds feel like waiting for an “intercity elevator”: the farther the distance, the longer the wait. Behind the scenes, what truly determines the experience isn't the server itself, but the content delivery network (CDN)—that “intermediate warehouse.” This article focuses on Bunny.net CDN, a provider renowned for its “low-cost + global node” approach. Through 14 consecutive days of real-world testing, we compared direct origin server access with Cloudflare, using data tables to visually demonstrate Bunny.net's performance in speed, stability, download...

When we talk about the “infrastructure” of the internet, Akamai is a name that cannot be overlooked. Founded in 1998, the company's very origin is closely tied to an internet legend. That year, MIT professor Tom Leighton witnessed an embarrassing scene where Tim Berners-Lee, the inventor of the World Wide Web, experienced a server crash while releasing a popular video due to excessive traffic. This incident directly gave rise to a revolutionary idea: why not distribute content across the globe, allowing users to retrieve data from the nearest node? This idea laid the foundation for the modern Content Delivery Network (CDN….
