TeamCity : Active-Passive
Hi Team,
We use TeamCity as our CI server. Right now TeamCity is a single point of failure in our infrastructure.
Working to have high availability. Can you please help with below queries ?
* At a time can we have both DB's on each datacenter as Read&Write ?
* Whats the suggested frequency of threshold to flip traffic via GSLB ?
* How can we keep build counter value in sync for both TC hosts ?
Any info would be really appreciated. ManyThanks!
Satish.

Hi Satish,
As of now, it's not posible to have multiple teamcity servers feeding from the same database and/or data directory. We are working on implementing an HA solution that will start as a main-node and read-only node in the upcoming 2018.1 release evolving in further releases to a more complete HA mode.
We have instructions in our documentation for replication environments: https://confluence.jetbrains.com/pages/viewpage.action?pageId=74845225#HowTo...-SetupTeamCityinReplication/ClusteringEnvironment
