Increasing Network Latency

We saw how we can deal with network failures. To be more precise, we saw one possible way to simulate network failures and one way to solve the adverse outcomes it produces. However, it’s not always going to be that easy. Sometimes the network does not fail, and requests do not immediately return 500 response codes. Sometimes there is a delay. Our applications might wait for responses for milliseconds, seconds, or even longer. How can we deal with that?

Let’s see what happens if we introduce a delay to requests’ responses. Is our application, in its current state, capable of handling this well and without affecting end users?

Inspecting the definition of network-delay.yaml

Let’s take a look at yet another chaos experiment definition.
