<\/p>\nZenlayer is a company that many people recognize first from its bare metal, global network or acceleration products, CDN is not the most famous line. But from the product structure, its CDN is more like an \u201cextension of the global network capabilities\u201d rather than a traditional CDN that sells cached traffic alone.<\/p>\n
Zenlayer's advantage is that it has 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. This also determines that its CDN is more suitable for cross-border and overseas access optimization, rather than simply pursuing the domestic extreme low latency.<\/p>\n
In terms of positioning, Zenlayer CDN is not like Cloudflare, a one-stop security platform, or Akamai, an ultra-heavy enterprise CDN, but is more geared towards providing a \u201cgood network foundation, uncomplicated rules, and cost-controlled\u201d acceleration solution to sites that already have some overseas business. It is also not like Akamai's super-heavy enterprise CDN.<\/p>\n
This test of the Zenlayer CDN was done for a couple of practical reasons:<\/p>\n
This test focuses on just three things:Whether the acceleration is obvious, whether the cache is stable, whether the source station can carry it when hit<\/strong>\u3002<\/p>\n The whole process is a real domain access, did not do any \u201clab optimization\u201d, caching rules are also used only the most basic configuration.<\/p>\n This model is more suitable for sites with relatively stable traffic, and less suitable for operations with particularly large daily fluctuations.<\/p>\n From the results, the cross-continental access latency is controlled in a more reasonable range, especially the emerging market node performs stably without significant jitter.<\/p>\n Zenlayer CDN is not an \u201call-in-one CDN\u201d, but it has its own advantages in terms of global network coverage and cross-region access. If your business is overseas oriented or you are already using Zenlayer's server system, adding a CDN is the way to go.<\/p>\n But if you're expecting a strong WAF, automated security policies, or extreme attack protection, it's not suitable as a sole line of defense. Overall, it's more like aA CDN with a solid network foundation, clear positioning, and no gimmicks<\/strong>\u3002<\/p>","protected":false},"excerpt":{"rendered":" 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.
