How do configure scaling based on latency in AWS Elastic Beanstalk?

Question

Latency of my application deployed to AWS Elastic Beanstalk is generally about 50 ms, I want another instance to start if average latency goes to 500ms (1/2 second). You can change the scaling Trigger in the configuration and select Latency , but the smallest Unit of Measurement is Second and Upper and Lower Scale Increments values must be an integer or percent.

So it doesn't seem possible to set a trigger as required.

Answer 1

The properties "Lower breach scale increment" and "Upper breach scale increment" is the number of EC2 instances to add or remove. This has to be an integer or a percentage.

For using subsecond latencies as triggers for scaling, set the values of UpperThreshold and LowerThreshold to "0.5" for 500 ms. The Unit of Measurement will be Second.
