Hi @Hiba_B ,
The UiPath Automation Suite Installation course has been released as planned, In November 2021. It’s available here: https://academy.uipath.com/courses/uipath-automation-suite-installation.
As for the diagrams, some of them are available on the UiPath Documentation portal, for example here: Deployment architecture
And if you have specific questions about Automation Suite, I’d suggest to check the threads under the Automation Suite category and ask the questions there. The product managers and software engineers are regularly checking those threads and answer the queries.
