For 100k Osquery hosts what are the recommend instance sizes for AWS Redis and RDS?

Elasticache:

cache.m5.large

RDS MySQL:

db.m5.12xlarge

(Estimated starting points -- this can vary quite a bit based on usage patterns)

Just trying to calculate a rough estimate with AWS calculator.

At most a few MB per host. Depends on how much you want to store for the hosts (if you enable software inventory, if you use the

host_additional

queries, etc.)
