I've started with simple application plus relational db example, like many startup companies from my experience start with. And started elaborate from this: 1. Adding nginx as a load balancer. 2. Adding blob storage for pictures/files. 3. Separating user likes and comments to different types of datastorage, like redis/document db 4. Creating master-master replication for relational DB in different regions
