CZ Podcast 136 — CDN77

For episode 136 we managed to snag Zdeněk Cendra and Veronika Miňovská from CDN77, and it made for a fascinating conversation. CDN stands for Content Delivery Network, which Zdeněk decided to build and run worldwide. Besides the technical difficulty (though Zdeněk will persuade you that it depends on how you look at it), you’re building a distributed system that has to scale on the internet and tackling the hardest problem in computing, cache invalidation. And you have to compete with big players like Akamai and the rest.
