Job Anti-Affinity in Action

Overview

This guide will walk you through creating and executing a job that will demonstrate Nomad's job anti-affinity rules and, in clusters with memory limited Nomad clients, filtering based resource exhaustion.

Sample Environment

• One Nomad Server Node
• Three Nomad Client Nodes
  • 768 MB RAM total (providing 761 MB RAM in nomad node-status -self)

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
