This looks great, and I am glad that there is a "Generic" set of nodes. I'm always a bit uncomfortable about architecture diagrams that lean too heavily into the names/icons of the specific cloud platforms that they use... i.e. describing WHICH AWS/Azure/GCP tech is being used rather than concern for WHAT or WHY those components are there for, which is much more important! It doesn't look like the edges between the nodes are labelled with any useful information either in this case.
Yeah, just about every diagram you see online commits these sins. Probably because companies that create detailed diagrams don't make them public. What's left is mostly diagrams by tech companies (e.g. cloud providers) created specifically to promote the technologies themselves.
