In this blog series, we’ve been looking inside Varnish to see what’s under the hood. There’s a lot more going on than meets the eye, beyond simple caching, beyond even Varnish Configuration Language.

The Core of Content Delivery: Varnish Private CDN

Content can’t be king without the CDN 

In mid-2021 a handful of catastrophic commercial CDN outages made the world take notice: the supposedly decentralized internet of the future has been centralized and served through an increasingly narrow set of CDN providers, making the entire internet more vulnerable to failure. Commercial CDNs offer scale and reach, but as these outages demonstrate, lengthy outages, revenue and productivity losses, and unhappy end-users aren’t great for business.

The Most Important Metric for Cleantech Content Delivery

Recently, Varnish Software and Intel announced a major step forward for streaming (and content) delivery, reaching almost 400 Gbps on off-the-shelf hardware. The Supermicro server was powered by 3rd generation Intel Xeon Scalable processors, running a new NUMA-aware version of Varnish Enterprise. Our performance benchmarks were featured in a demo at Mobile World Congress, available here.

Reaching almost 400 Gbps on a standard server is likely a new record for standard software, which may have a disruptive impact on existing hardware and software technologies that sometimes can only deliver a tenth of this capacity.

Being the fastest and most performant is in the DNA of Varnish Software, and our core engineers are obsessed with breaking boundaries like this (expect them to reach even higher). Working with amazing partners like Intel to achieve benchmarks like this is very exciting for us, but there is also an important reason behind it.
