The Proxy Server load will vary over the day and over the week. We can save about 30% in server costs if we automatically scale the number of tasks. My initial idea is to scale based on CPU load, but that's something we could test with a load test.

Autoscaling has been added to the proxy server. Scaling activity will happen based on the following conditions:

  • Scaling up is based on breaching the average CPU alert threshold of > 51% for 2 consecutive periods of 60sec (120sec in total). If triggered, it will add 12 tasks to the current capacity.
  • Scaling down is based on breaching the average CPU alert threshold of < 40% for 2 consecutive periods of 300sec (600sec in total). If triggered, it will remove 6 tasks from the current capacity.

woo hoo! Thank you Hristo! \o/
