> Mesos enables flexible deployment of tasks in a shared cluster. A task may
> run on any slave and even move between slaves based on resource availability,
> framework shares, slave failures, and other constraints. To make the most of
> this flexibility, we need an automatic way to discover where tasks are and
> how to connect to the services they provide. To address this need, a number
> of service discovery systems have been proposed, based on proxies, DNS, or
> consistent stores such as Zookeeper and etcd.
> Any service discovery system needs to draw information about currently
> running tasks, their location, and their configuration parameters (IP
> address, ports, etc). In a Mesos cluster with multiple frameworks, the only
> authoritative source of information about running tasks is the master itself.
> In order to automatically manage the service discovery system, the task
> information available in the master should include service discovery
> preferences and parameters.
> If service discovery information is not available in the Mesos master, Mesos
> users will likely have to build auxiliary systems that gather and serve this
> information. Keeping the information in such auxiliary systems consistent
> with the task information in the master will only cause complications in the
> long term. It is best to store service discovery information along with all
> the other task information in the Mesos master.
