I am in the process of designing SharePoint 2016 environment for our organisation. We have so many intranet web applications and also has many anonymous public facing sites existing in different Farms (WSS 3.0,MOSS,SharePoint 2010,SharePoint 2013 etc). We are planning to migrate all these sites to SharePoint 2016 platform.
I am thinking to create 2 separate Farms - One for Intranet and another one for internet sites.I am planning to use host named site collection approach to host intranet sites so that all the site collections can be created and managed under the same web application.
Still I am in a confusion whether it will be a better idea to host anonymous sites as host named site collections under the same web application or create separate web application for each site. Anonymous sites are accessed by our various vendors and each site is targeted to different set of users.
Request your suggestions.
