18 SUPPORT AND PURCHASING

19 PURCHASING AND SUPPORT: SERVERS Server Support Ecosystem Has Evolved to Fit Business Needs By a show of hands Where do you buy your server hardware: Direct from hardware vendor? Partners? VAR? Where do you buy your server OS and applica5ons? Direct from soqware vendor(s)? Partners? VAR? Who do you call if there is a problem? or hardware supplier? Or a VAR? 2013 BIG SWITCH NETWORKS, INC. 19

25 SUPPORT PROGNOSTICATIONS Which support process will dominate? Rapidly evolving: our customers use all of these Depends on geographic region: Japan à VAR, EMEA à partner, US à direct Claim: Single throat to choke will transivon to VAR then direct sales. SoJware Licenses: subscrip8on versus perpetual plus support Depends on company size, internal accounvng Both may be the right long term answer Larger quesvon than networking soqware B I G S W I T C H N E T W O R K S, I N C.
