title: App container to cassandra node - one to one or?
body: <p>I am using containers to run both app servers &amp; Cassandra nodes.</p>
  <p>When starting the app server container, I need to specify which Cassandra node(1..n) to connect to. How would you divide the workload?</p>
  <ol>
  <li>One app container to one or more Cassandra nodes(How many).</li>
  <li>One or more app container to one Cassandra node(How many).</li>
  <li>Many to many(How many).</li>
  </ol>
  <p>This is for a production setup, 100 % uptime. Each data load from cassandra is small but many.<br>
  <br>I should be scalable so I can put in more app containers - like in Kubernetes they have pods. Pods is a set of nodes that make up granules of the application.
  <br>Therefore I am looking for the best possible group of containers(Cassandra and App server) that will scale
  <br><br>
  Info: Kubernetes is a to expensive setup in the beginning. And while waiting for Docker Swarm to be in release state I will do this manually. Any insight is welcome?</p>
  <p>Regards</p>
