I use this OATS OpenScript technique for several advanced script control needs. This example only shows how to stop the "content length is zero" error, though this can be used as a template for any advanced control of virtual users.

Algo VPN with enhancements

ALGO VPN running in an AWS Spot instance

Given the highlights from the Alestic blog Feb-2018, now enhance the Algo VPN Ansible script to start a spot instance vs on demand instance.

Alestic blog highlights reason to enhance algo script

  • Can run an instance like you normally do for on-demand instances. One new parameter can make it a Spot instance
  • Spot price volatility has been significantly reduced
  • No longer have to specify a bid price
  • CloudWatch Events can now send a two-minute warning before a Spot instance is interrupted
