Best Practice Architecture for MID servers in an international corporate infrastructure

[curtisrowell]

Given the following geographical regions, EMEA, NA, Latin America, APAC; assuming there are corporate data centers for each of these areas, is it a reasonable assumption to place one or more MID servers in each geographical data center to handle the traffic which originates from that area?

If we have one DNS entry for the MID server cluster and use network routing rules to determine which data center cluster would be utilized so that someone in Dallas or Mexico City would go to the NA Cluster; Guatamala or Brazil would go to the Latin America Cluster, Ireland or Italy would go to the EMEA Cluster and Philippines or Japan would go to the APAC Cluster.

Hi Curtis,

placement in the regional DCs makes sense for me.

The real question you'd have to answer though is - what sort of information are you going to transfer by these MIDs?

Discovery? Integrations? Other data sources?

It's should place you MID Server(s) as near as possible to your data. Geographically. If you think about the amount of data a discovered server may produce, as such as other variables of your environment, like:

• Number of subnets being discovered at once
• Resources available on the MidServer
• Available bandwidth between MidServer and targets
• Resource availability (utilization) on the targets
• impact, throughput, caveats, warnings, impact
