You can scale HANA vertically and horizontally. Vertical makes sense for ERP workloads where you want low latency (avoiding communication). The ERP workloads of most companies can fit in RAM easily nowadays. Horizontal scaling is best for data warehousing/analytical workloads, which tend to be more CPU bound due to lots of calculations.

Horizonal scaling costs more in base licensing, not to mention whatever 3rd party stuff you're running in your Hana. Enough to encourage scaling up as far as you can before scaling out.

Nah, with scaling, I‘m more referring to approaches of eg Cassandra instead of „add another read replica“.

I wasn't talking about replicas either. HANA can distribute data over many clusters.

HANA's roots lie in BWA (SAP BW accelerator), whose main game was distributing large amounts of data across commodity clusters.
