Single Connect Redundancy Testing
Health check control is done with http request to port 80 or 443. Receiving HTTP Code 200 OK as a response means that the service is up. The mentioned control is performed by the load balancer belonging to the company. Single Connect nodes do not load balancing within themselves. Requires independent load balancer for load balancing.
It will be sufficient to run the following commands in the cli with the authorized user. UI Service
Proxy Services
After the related services are stopped, the load balancer Health check will fail and all traffic should be forwarded to other nodes. After the load balancer directs the traffic, it is seen that the data in the Single Connect is up-to-date and there is no problem in receiving the traffic.
Single connect provides data redundancy with database. When the services at the application level are stopped, the database will continue to be redundant.
UI and Proxy Start command
After shutting down Single Connect server, the load balancer Health check will fail and all traffic should be forwarded to other nodes. After the load balancer directs the traffic, it is seen that the data in the Single Connect is up-to-date and there is no problem in receiving the traffic.
When server is turned on again, the difference between the database will be synchronized by the replication. During the synchronization process, the server will be actively available. Single Connect nodes will continue to provide up-to-date services.
In structures where load balancer is not used, Single Connect can continue to use and redundancy test by accessing the other node ip address.
