Load balancing across multiple clusters
Hi,
I am pretty new to load balancing technologies, so need some help here.
I am thinking of using LTM across two sites, situated about 500m apart. Since the distance is pretty short, especially with the use of fiber cables between the two sites, I think it might not be necessary to use the GTM. Part of my network design is attached, the distribution switch connects to other part of the server farm.
I have some doubts which i need to clarify:
1. The linkage between the two sites will span across the distribution switches. May I know if load balancing will work across the two sites? Or do I need to connect the load balancers from the two sites directly?
2. I am using load balancing between different applications - app, web and terminal server. Can i share the load balancers for these 3 clusters, or do i need a separate load-balancer for each application? Does configuring multiple pooling address this?
3. May I know what benefits do Layer 4 and layer 7 load balancing provide? And also for this configuration, what specifications do I need to look out for in the distribution switch? Layer 2? Layer 3?
