This increases hikari fetch size to 40 from 20 in order to decrease the
amount of round trips
This also sets lower CPU as we seem to have overshot CPU consumtion
This also set min replicas to 8 for EPP and max to 16 as we've been
running on 8-10 for the last week
Missing resource requests as well as metrics for when to evict resource
produced situation when under load k8s struggled to assign pods. This
adds default resource requirements based on 2 weeks metrics and
instructions when resource should be evicted.
From our investigation, the Monday night WHOIS storm does not cause any
strain to the backend system. The backend latency metrics are all well within
the limits. The latency measured from the proxy matches observed latency
by the prober, and we see that the "used" CPU is 1.5x of "requested" CPU
during the time when the latency is above the threshold.
Making this change hopefully removes the proxy as the bottleneck and
ameliorate the pages.
* Move terraform and kubernetes folder to be under proxy
There is no reason for them to be under proxy/src/... any more now that
we have a Gradle-idiomatic folder structure.
