Who is this presentation for?

  • Developers, DevOps engineers, engineering managers, and engineering team leads

Prerequisite knowledge

  • Experience running a highly available service with an orchestration system, such as Docker Swarm or Kubernetes

What you'll learn

  • Explore the main challenges of running a distributed system (state management, scheduling, etc.)
  • Understand what quorum is, and how it is achieved, the right number of managers needed for your distributed system, the process of leader election, and task scheduling algorithms

Description

Orchestration systems attempt to take the complexity out of running highly available services, but in truth, they just abstract that complexity away from you as the user. Orchestration systems have two main areas of focus—maintaining consensus and scheduling tasks—from which many counterintuitive patterns emerge that can be disastrous in production if not treated with caution. (For example, running a cluster with two managers actually doubles your chance of losing quorum.) Unfortunately, these problems aren’t easily recognizable on the surface.

Laura Frank explores the algorithms that power all modern container orchestration platforms and shares actionable steps to keep your highly available services highly available. Instead of learning things the hard way in production, join Laura to gain a deeper understanding of the complex topics behind your production applications.
