Mysos – MySQL on Mesos 11 years ago
Mysos follows similar steps, it just automates them for you. Mesos gives the scheduler abstracted resources and finds the box to launch the MySQL task. The task still needs to install MySQL (possibly pull the package from HDFS) and recover the state (also possibly pull from DHFS). These things are specific to the organization's workflow and the MySQL task's behavior can be customized by implementing interfaces for these steps. Mesos bridges the central scheduler and the MySQL instances distributed across the datacenter so it can monitor them, make centralized decisions and communicate with the instances reliably.
