Zac Smith, managing director Equinix Metal, is sharing how Equinix Metal runs the best hardware and networking in the industry, why pairing magical software with the right hardware is the future, and what Open19 means for sustainability in the data centre. Think modular components that slot in (including CPUs), liquid cooling that converts heat into energy, and a few other solutions that minimise the impact on the environment.

But first, Zac tells us about the transition from Packet to Equinix Metal, his reasons for doing what he does, as well as the things that he is really passionate about, such as the most efficient data centres in the world and building for the love of it.

This is a great follow-up to episode 18 because it goes deeper into the reasons that make Gerhard excited about the work that Equinix Metal is doing. This conversation with Zac puts it all into perspective.

By the way, did you know that Equinix stands for Equality in the Internet Exchange?

Maddy Mail Server implements all functionality required to run an email server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).

It replaces Postfix, Dovecot, OpenDKIM, OpenSPF, OpenDMARC and more with one daemon with uniform configuration and minimal maintenance cost.

IMAP storage is still in beta, but this is one to watch as it could dramatically simplify your infrastructure.

This thing has a feature list a mile long including a REST API to manage users and quotas.

A million apps isn’t cool. You know what is cool? A billion apps! Per overwhelming request from language communities Passenger didn’t previously cater to, we introduce generic language support in Passenger 6. Launching in 3, 2, 1…

Passenger began as a Ruby application server, eventually adding support for Node.js, Python, and Meteor apps. Congrats to the relentless team at Phusion for bringing their much-beloved server to even more developer runtimes!

It is 100% compatible with HAProxy, and takes full advantage of the ACL functionality of HAProxy to provide fine-grained caching policy based on the content of request, response or server status.

The feature list is long. Click through to see ’em all.

Nuster is very fast, some test shows nuster is almost three times faster than nginx when both using single core, and nearly two times faster than nginx and three times faster than varnish when using all cores.

Here’s a detailed benchmark backing up these claims.
