Hi Billy. By core I mean your core data center(s). By edge I mean remote or branch offices where you don't have a full data center but you may have some data center equipment running. You can taking advantage of Big Data by having infrastructure designed for your big data solution. In the case of Cisco, we have design guides to help you choose and configure the right hardware to support big data solutions like Cloudera, MapR, Splunk, etc. You can find those design guides here: https://www.cisco.com/c/en/us/solutions/design-zone/data-center-design-guides/data-center-big-data.html
