Rate Limit : Product level vs App level vs KVM level

[JossySebastian]

Hello Team,

  I would like to know rate limiting behavior in APIGEE at product level vs app level vs kvm level. Appreciate your help to share any documents on the above 3 points.

Also what are the pros and cons of implementing product level, app level and kvm level?

Appreciated your response.

Many Thanks

Jossy
