SAP HANA One is an inexpensive, private cloud-based instance of the SAP HANA platform, hosted in the Amazon Web Services (AWS) cloud. SAP HANA is a data warehouse appliance for processing high volumes of operational and transactional data in real-time.
SAP HANA One includes roughly 30 GB of usable RAM per instance, making the cloud platform suitable for companies that want to conduct proof-of-concept projects, build and deploy HANA applications for production use or get started with in-memory applications. SAP also recommends SAP HANA One as a way for independent software vendors (ISVs) to build and deliver SAP HANA applications.
