2. INTRODUCTION
 The CEO of Mesosphere, Inc., which he founded in 2013, Florian “Flo” Leibert
manages the Internet start-up’s recruiting, financing, and business operations. In
addition to his numerous achievements with Mesosphere, Florian Leibert
created Chronos while working with Airbnb.
A fault-tolerant scheduler that runs as part of the open-source Apache Mesos
software, Chronos is a replacement for the Cron command used in computing to
tell a server or operating system the specific time for execution of a task. It
supports a range of custom executors in Mesos, in addition to the default
command executor.
Further, Chronos is capable of interaction with systems like Hadoop, even in
cases where the Mesos agents related to task execution don’t have Hadoop
installed. Chronos uses asynchronous callbacks to provide notifications of task
completion or failure, in addition to being capable of transferring and executing
files on remote machines running in the background.
Chronos’ advantages over Chron include the ability to support long dependency
chains, increased flexibility in task scheduling, and the ability to define tasks
based on the completion of previous tasks.
