We do have around 150 branch offices with low bandwidth and low amount of clients (5-10 clients) there - Secondary site servers will be used at every branch office. To reduce the amount of traffic generated during updates deployment the follwoing question came up:
As every client will contact the WSUS database (SCCM distribution points are only used to get the updates content), would it be better to have a locally installed WSUS in every branch office which does mean that the WSUS database (up to 4GB) must be replicated from the central WSUS over the WAN. Or would it produce less traffic to have only a central WSUS where all clients connect to?
So amount of traffic generated by all branch office clients contacting the central WSUS versus amount of traffic for WSUS db replication (branch office WSUS from central WSUS).
Thanks
