Caching software specialist Varnish Software has announced native TLS support in the latest release of Varnish 6.0, providing what it says is an industry-first certified 150Gbps for each server. The ability to reach content delivery speeds in excess of 150Gbps from a single server/instance is considered a significant moment for content delivery as it will allow streaming services to serve more data without the need to invest in additional resources. The updated software solution is already used by Sky among others.
“Benchmark tests with customers reached 160Gbps and show that Varnish 6.0 with native TLS is now the fastest and most resource efficient content delivery solution available,” the vendor comments.
The previous iteration of Varnish 6.0 guaranteed that Varnish Software customers could deliver 100Gbps per server, but separated TLS and the core caching components into two processes, which required additional resource usage. By developing native TLS support into the core Varnish software, this additional network step has been removed, ensuring customers are now able to reliably serve more data with less resource usage.
High performance caching and edge computing is key to unlocking the potential of 5G for content delivery. Varnish 6.0 with native TLS support will help content owners manage as much traffic as possible at the network edge, relieving the burden on origin servers. This, in turn, will keep traffic flowing even under testing conditions. UHD video streaming will be one obvious beneficiary.
Espen Braastad, VP Engineering at Varnish Software, says: “The marriage between architectural efficiency and network scale is essential for the success of any modern content delivery platform. Achieving more than 150Gbps while still maintaining reliable, low-latency content delivery means our customers can stay ahead of the curve and have more than enough capacity for their current and future needs.”
