// Key takeaways
- Edge Delivery and Document Authoring, end to end: what each piece actually does
- CDN and edge workers in front of EDS — where the seams are
- Authenticating DA and wiring it to GitHub
- Block-aware bulk search and replace across a content tree, without scripting
What we covered
Two sessions. The first walked the building blocks of a modern Edge Delivery / Document Authoring site — how EDS, DA, the CDN layer and AEM Cloud backends fit together, and which customisations are worth making. The second demonstrated safe bulk content updates in EDS/DA: finding content by block and property across a whole tree, versioning before changing anything, and undoing a bulk edit that went wrong.
