Description:

The tech talk is going to discuss Salt as a case study of an on going project at LinkedIn to evaluate Helix to manage clusters of Salt Masters to alleviate problems caused by a very lopsided salt master to salt minion ratio. The tech talk will use salt as a case study to demonstrate how high volume python applications can be written to be managed by Helix.

Apache Helix is a generic cluster management framework used for the automatic management of partitioned, replicated and distributed applications hosted on a cluster of nodes. Helix automates reassignment of resources in the face of node failure and recovery, cluster expansion, and reconfiguration. Apache Helix was originally developed at LinkedIn to manage some of our high volume applications

Saltstack's Salt is a remote execution and orchestration tool, counted in the company of other tools such as puppet, chef ansible etc. LinkedIn has one of the largest deployments of salt anywhere in the world.

Topics to be covered:

  • Covering basics of cluster management and traditional cluster management solutions
  • Introduction to Finite State Machines
  • Introduction to Apache Helix and Zookeeper and related concepts
  • Introduction to Python libraries used for Helix and Zookeeper
  • Real Code examples to demonstrate implementation
  • Potential use cases outside Salt

Prerequisites:

The talk assumes some familiarity or curiosity about high volume applications and general understanding of clustering, partitioning etc. Some reading of the following links might be helpful but is not necessary
