Ashley Hazle Hogarth Worldwide, London, United Kingdom Config management (CM) is now commonplace, yet there are still people who are struggling to navigate the multitude of CM modules and with getting the basics right. We have gone from running dozens of D8 sites without any config management to well over 100, as a single multisite, running with shared config. This session would jump into getting 1 site running with CM, including relevant modules such as using split for environments and working with Webforms. Then show how to upscale your config to work with a large 100 sites multisite. Closing with showing how the learnings from a large multisite can help you structure you CM better, and make it more reusable and portable.
