Diagram ¶
- Global DNS router build on Route53 in AWS, so the healthcheck need hit on the external ingress.
- EMS frontend, backend and Redis are deployed in Kube cluster, frontend have 1 replica, backend have 3 replicas in prod and 1 replica in bts. Redis has 6 replicas.
- EMS DB is PostgresSQL, deployed on dedicated DB servers outside kubed and use shareplex for data replication between primary and GSB side.
Deployment ¶
EMS is deployed on two Kube clusters in two different DCs, one is primary side in JFK, another is GSB side in DFW.
