First of all let me describe the current architecture:
wM version 9.6
There are two different data Center:
First Data Center:
4 Intergration Servers in Clustered Environment.
Second Data center(trying to setup):
4 IS- Not Clustered yet
Each data Center has its own local load balancer. There is also a Geo Load Balancer which routes the requests across to the local load balancer.
Both first and the Second data Center is connected to the same database.
My questions are as follows:
Since client application is connecting to our integration server via the geo load balancer, do we need to have the Integration servers in cluster? I have tested that the schedule services works similar to a clustered setup while its connected to the same Database ie only one runs at a time.
I do not have much concepts in Clustering of Integration server. can someone please assist on the benefits of clustering given the load balancer setup specified above.
Please note we only use local publish.
