High-Availability/Disaster Recovery Options
Currently my SW environment is running on single datacenter DC1 with (1 primary and 2 additional polling engine with 1 SQL server)
We are planning to create one HA in DC2 with 1 polling engine and 1 SQL server replica of primary SQL server and another polling engine in DC3
Is this possible to create above environment? Can my additional polling engine (DC2 & DC3) can also working normally to help divide load for other polling engines under DC1?
need to get recommendations from those who are familiar with the setup
