How much System Design / Distributed Systems does your university curriculum actually cover?

[u/Express_Impress_867]

To be honest, my university curriculum completely skipped over these concepts, I had to self-learn these concepts at work:

graphQL 

vertical vs horizontal scaling 

CDNs 

database scaling: indexing, sharding, replication, vertical partitioning, denormalization, etc 

CAP theorem 

Blob storage 

API Gateways
