the Ingress that passes all things to Cortex
will be scraping and pushing data to cortex

Ring organize how samples gets ditributed on ingesters

ingesters
we are running with replication factor of 3 which means that for a sample that is recieved it gets sent to all 3 all 3 cortex instances
if go to the cortex ring interface we can see that all cortex nodes are running and shares equal amount of data as we have set the replicaSet to 3 in our yaml file
we are running 2 prometheus replicas which means we are HA but cortex also allow to deReplicate which means when running 2 replicas ar erunning we can choose to only use one of 2 replicas and this is where consul is used
consul is only used for the HA
lets one promtheus to be scraped only when one of them is running
so for Common cluster it selects one of the replicas 8
