It seems we’ve crossed the line from people talking about deploying Cassandra on top of Kubernetes in production to actually doing it. Patrick McFadin (<a href="https://twitter.com/patrickmcfadin?lang=en">@PatrickMcFadin</a>) interviewed several of these early adopters in <a href="https://www.datastax.com/accelerate/why-tomorrows-cassandra-deployments-will-be-on-kubernetes">this fascinating episode</a> from the Accelerate online series.

There was so much goodness we released the original conversations on the Distributed Data Show (<a href="https://open.spotify.com/show/4AGVf2NOLNunlurLalQGnE">Spotify</a> | <a href="https://soundcloud.com/datastaxdevelopers">SoundCloud</a> | <a href="https://www.youtube.com/playlist?list=PL2g2h-wyI4SrpqV0IlckCKnDFsSxSyjxm">YouTube</a>):&nbsp;

Speaking of a common Cassandra Kubernetes operator, there’s already a Special Interest Group (SIG) hard at work! Check out the draft specification on <a href="https://cwiki.apache.org/confluence/display/CASSANDRA/2020-05-07+Cassandra+Kubernetes+Operator+SIG">Apache Cassandra Wiki site</a>.&nbsp;
