Multi-sites
Multi-site is a feature that allows you to run multiple sites off a single installation of your website. This is best suited for the type of website that needs to show a group of pages for a short period of time, such as a wedding business that will display a new wedding for clients but doesnt need a full site being built; or a marketing site that needs to host a marketing page for a short time.
Prior to version 9, the Domain Mapper add-on enabled a single Concrete installation to route multiple domains to different top level pages. In version 9 this feature is fully included, and allows content editors to set up different types of sites, default permission groups across sites, default site attributes per site type, and more.
With all sites under one shared set, Multi-site makes it easy to spin up clone sites which reduces the time needed to update Concrete, themes and packages.
Clearly this is a more expensive option but gives a lot more flexibility and also does have a higher build therefore maintainance cost.
When should you use multi-site?
Multi-site configuration can be beneficial in certain cases, but in others it can lead to administrative problems. It is important to understand what Multi-site is, therefore what problems it was designed to address before you make the decision to use it. Concrete Multiple Site Hosting is best to use when you are creating a network of sites sharing similar functionality. Ideally, this similar functionality has been added through Blocks and themes. If your sites consist of widely different sites and their functionality, then multi-site is not a good fit for you.
