NOTE: The Apache Aurora project has been moved into theApache Attic.A fork led by members of the former Project Management Committee (PMC) can be found athttps://github.com/aurora-scheduler

Apache Aurora lets you use anApache Mesoscluster as a private cloud. It supports running long-running services, cron jobs, and ad-hoc jobs.Aurora aims to make it extremely quick and easy to take a built application and run it on machinesin a cluster, with an emphasis on reliability. It provides basic operations to manage servicesrunning in a cluster, such as rolling upgrades.

To very concisely describe Aurora, it is like a distributed monit or distributed supervisord thatyou can instruct to do things likerun 100 of these, somewhere, forever.

Aurora is built for usersand operators.

• User-facing Features:

  • Management oflong-running services
  • Cron jobs
  • Resource quotas: provide guaranteed resources for specificapplications
  • Rolling job updates, with automatic rollback
  • Multi-user support
  • SophisticatedDSL: supports templating, allowing you toestablish common patterns and avoid redundant configurations
  • Dedicated machines:for things like stateful services that must always run on the same machines
  • Service registration: announce services inZooKeeper for discovery byvarious clients
  • Scheduling constraintsto run on specific machines, or to mitigate impact of issues like machine and rack failure

• Under the hood, to help you rest easy:

  • Preemption: important services can 'steal' resources when they need it
  • High-availability: resists machine failures and disk failures
  • Scalable: proven to work in data center-sized clusters, with hundreds of users and thousands ofjobs
  • Instrumented: a wealth of information makes it easy tomonitorand debug

Aurora can take over for most uses of software like monit and chef. Aurora can manage applications,while these tools are still useful to manage Aurora and Mesos themselves.

However, if you have very specific scheduling requirements, or are building a system that looks like ascheduler itself, you may want to explore developing your ownframework.
