GTM Topology configuration
Hi,
I have a configuration dilema that I am not sure how to resolve.
Here is the scenario. I have 3 GTM's all in one location, so all queries will go the same geographic location. I need to load-balance (for lack of a better term) DNS queries between 4 different servers based on client-IP. The servers are located in:
Oklahoma
Colorado
Singapore
Korat
I have created 4 different data centers and placed the Singapore, Colorado, and Korat servers by themselves in their own datacenter. The Oklahoma servers already has a datacenter with several other IPs.
I need clients from Singapore to get handed back the server in Sinagapore, etc...
My question is this. Which would be better suited, topology or an iRule. There is 1 wideip and 1 pool that contains the 4 other servers (actually pools of servers. I created 1 pool for each location).
I could configure topology but I am not sure how to set it up so that I don't run into issues with any other future topology plans. IE: Should the destination be based on datacenter location of specific pool or regions?
Or should I just use an iRule. Any help or suggestions?
Thanks,
Kevin
