As noted in another comment, we, a growing starting with 5 people around software out of 15 people total, run a Mesos cluster with a couple of hundred machines. By FAR our largest challenge has been to adapt our thinking to break the "this machine is 'production', that machine is 'staging'" mindset. We have a production compute infrastructure and you're welcome to launch 'production', 'staging' or whatever jobs into it. The friction around "running Mesos" has mostly been the friction of the air from exhalatoins of joy buffeting our esophagi... We have a separate, much smaller cluster to test new Mesos (and Chronos and Marathon) versions. But the distinctions "production", "staging" and "dev" have become much more nuanced, so we've settled on discussing the "application" environment versus the "infrastructure" environment. Much as, as a startup on AWS, you wouldn't distinguish the RDS instance of your database (e.g. 9.3.1), you would distinguish the version of your database on an RDS instance, we distinguish the versions of our apps on the production cluster and not the version of the production cluster. One of the team was an ex-Googler and he said that Google did much the same. The one thing Marathon and Chronos currently lack is a prioritization mechanism so we're building that as a Chronos task that monitors and scales down/up Marathon tasks by their priority (as represented in their id or tag). |

Is there some common phrase relating belching and being happy that I haven't heard?
